Richardson’s Skua reaches its breeding-grounds in the British Islands early in May. Its haunts at this season are open moors, at no great distance from the sea. Although social at its breeding-places, it can scarcely be described as gregarious, and the nests are usually scattered up and down the moorland area. This Skua appears to pair annually, and the nest, always made upon the ground, is merely a hollow, carelessly lined with a little dry herbage, and sometimes nothing but a shallow cavity in the moss. The eggs, normally, are two, but sometimes three have been found, and occasionally but one. They range from olive to brown in ground colour, spotted and speckled with darker brown and grayish brown. Incubation is performed by the female, and lasts about a month. At its breeding-places Richardson’s Skua is very demonstrative, and often reveals the situation of the nest by its anxious movements above the intruder’s head. After the young are reared the moors are deserted, and for the remainder of the year this Skua is decidedly pelagic in its habits and haunts.
We now pass to the Terns. These pretty graceful birds—widely known as “Sea Swallows”—differ in many respects from the Gulls and Skuas. They most closely resemble the former in general appearance, but may be easily distinguished by their slender form, small size, and forked tail. Of the dozen species that have been regarded as“British,” no less than five breed within the limits of our islands. The Terns are far more locally distributed than the Gulls. Many miles of coast may be traversed without one ever seeing a Tern. They are all migratory birds with us, visiting Britain in summer to breed, and retiring south again in autumn. It is only during the season of passage, therefore, that they are at all widely dispersed, for the remainder of their sojourn on our coasts is spent at or in the near vicinity of their breeding-stations. The five indigenous British species follow.
This fine species—theSterna cantiacaof Gmelin, and theS. sandvicensisof Latham—is not only the largest of the indigenous British Terns, but one of the rarest. It was formerly much more widely dispersed along our coasts, but persecution has thinned its numbers, and the seaside holiday-maker has banished it from many of its old-time haunts. Special interest attaches to this bird, because it is one of the very few species that have been first made known to science from examples obtained in the British Islands. It was first discovered in 1784, at Sandwich, on the coast of Kent, and described by Latham three years later. Alas! no longer does this beautiful Tern breed in its early haunts on the Kentish coast; it has disappeared from there, as it has from many another locality, withouthope of return. The most important breeding-place of this Tern, and certainly the most accessible to the majority of observers, is situated on the famous Farne Islands; even here the bird is much less common than it used to be. There are small colonies on Walney Island, in Cumberland, in the Solway district, on Loch Lomond, in the Firth of Tay, and on the coast of Elgin. Its only known breeding-station in Ireland is in Co. Mayo.
The Sandwich Tern reaches the British coasts in April or early in May. But little is seen of this species whilst on passage, for it evidently keeps some distance from shore as a rule, or passes quickly and unobserved. The smaller Terns, for instance, are commonly seen on the coast of South Devonshire in Spring and Autumn, but I cannot recall a single strong migration of the present species in that locality. This Tern is seldom or never seen at any distance from the sea. Most of its waking time is spent in the air, flying about with easy, graceful motion, in quest of its finny prey. The Sandwich Tern, however, is nothing near so graceful looking on the wing as its smaller relatives, the heavier body, broader wings, and much less acutely forked tail giving it a heavier, more cumbersome appearance. Most of its food is obtained whilst it hovers above the sea. The way in which all the Terns feed is very pretty. They poise and hover above their finny victims, andevery now and then dart downwards like a stone into the water and capture a fish, fluttering up again, or remaining for a moment to swallow their capture. A flock of Terns (of any species) fishing is one of the prettiest sights imaginable. In addition to small fish the Sandwich Tern devours crustaceans of various kinds, whilst its young are fed largely upon sand-lice and beetles. The Terns are much cleaner feeders than the Gulls, and I have never known them touch carrion or refuse. I have, however, seen them pounce down upon scraps of food thrown from a vessel. The usual call-note of the Sandwich Tern is a somewhat shrill scream.
This Tern probably pairs for life, and returns regularly every season to its old-accustomed haunts to breed. These are by preference low, rocky, or sandy islands, covered with marine herbage, varied with barer patches, and with beaches of rough shingle. Similar conditions are sought on the mainland, in a secluded spot on the coast, but an island is always preferred. The Sandwich Tern is gregarious, but its colonies, with one exception, in our islands are nowhere very extensive. This one exception is at the Farne Islands, where it has been computed the birds number upwards of a thousand pairs. As the nesting-places are visited very regularly year by year this Tern probably pairs for life. I have noticed, however, that the birds shift their actual breeding ground from time to time,using several spots in succession. One year they will nest here, another year there, on the same small island perhaps, but sometimes removingen masseto another one of the group. The nests are always placed upon the ground, either amongst the sand shingle and drifteddebris, a short distance from high water mark, or amongst the sea campion, thrift, and coarse grass further inland; sometimes a bare mound on the highest part of the island is selected. Many nests are made within a small area, sometimes so close together as to render walking amongst them without treading on their contents a difficult matter. The nests are slight enough, mere hollows lined with a few bits of withered herbage, and in some cases even this simple provision is neglected. The eggs, which are laid from about the middle of May to the middle of June, are generally two in number, but sometimes three. These vary from creamy-white to rich buff in ground colour, handsomely blotched and spotted with various shades of brown and gray. During the hot June days the eggs seem to require little incubation, but there are always plenty of birds about the spot, ready to rise fluttering and screaming into the air when their breeding grounds are invaded by man. But one brood is reared in the season, yet if the first clutches of eggs be lost they will be replaced.
This Tern, known as theSterna hirundoof Linnæus, by most British ornithologists, although there can be little doubt that the great Swedish naturalist applied the term indiscriminately to this and the Arctic Tern, is one of the best known British species, especially round the English and Welsh coasts. It becomes rarer in Scotland, where it is largely replaced by the Arctic Tern. The Common Tern, distinguished by its white underparts from the Arctic Tern, is migratory and arrives on the British coasts towards the end of April, retiring south in Autumn. Its favourite haunts during the summer are the various groups of low rocky islands, and the more secluded portions of the coast where sandbanks and shingle occur. Save on passage, this Tern is seldom seen far from the vicinity of its nest colony. The flight of the Common Tern is exceedingly buoyant and graceful, the long slender wings and acutely forked tail assisting greatly in the general effect. Like the Swallows the tarsus of the Terns is remarkably short, so that on the ground the birds seem awkward, and rarely attempt to walk far; on the sea, however, they are quite at home and swim well. There are few prettier sights along the shore than a flock of Terns busy in quest of food. Where the beach is rocky, and the water somewhat deep inshore, thebirds may be watched with ease. In a serried throng they flutter to and fro; ever and anon a bird falls down like a fragment of white glittering marble into the sea with a loud splash, and in a moment rises again with its finny prey. Bird after bird keeps dropping so; now and then a bird remains swimming on the water; now and then two birds chase each other in rapid flight. And so for miles the Terns will continue to follow the shoal until hunger is satisfied, or the fish retire to greater depths. The food of this species is chiefly composed of small fish, but insects and crustaceans are also devoured. The note of the Common Tern is a shrillkrickorkree-ick, most frequently uttered when the bird is flying alarmed over its invaded nesting place.
The Common Tern is rather a late breeder, its eggs not being laid until the end of May or early in June. It breeds in companies of varying size, the suitability of the site being in some measure a determining cause. This Tern is equally capricious in the site selected for the nests; sometimes one spot is chosen, sometimes another; but there can be little doubt that the bird pairs for life, and evinces considerable attachment for its accustomed haunts. I have found almost invariably that the Common Tern habitually lays its eggs farther from the water than the Arctic Tern, and always prefers to conceal them amongst vegetation of some kind. Islands are always preferred to the mainland,doubtless because of their greater safety. We cannot class this bird as an elaborate nest builder, a mere hollow, scantily lined with a little withered grass or weeds, being the only provision. The two or three eggs vary from buff to grayish-brown in ground colour, blotched and spotted with several shades of rich brown and gray. But one brood is reared, and as soon as the young are strong upon the wing, the nesting places are deserted, and the movement south begins.
Terns migrate leisurely in autumn, often remaining a day or so here and there, on and off the coast, and are then seen in localities which they never frequent during summer.
This Tern, widely known to systematists as theSterna arcticaof Temminck, was unaccountably confused with the preceding species, until the German naturalist, Naumann, appears first to have pointed out their specific distinctness. The Arctic Tern ispar excellencethe Tern of our northern coasts, say from the Farne Islands and Lancashire onwards to the Orkneys and the Shetlands. I am not aware that it breeds anywhere on the English coast between Spurn and the Scilly Islands, but there are a few scattered colonies on the west coast of England and Wales. This pretty Tern may be distinguished from its near ally, the Common Tern(which it closely resembles in size and general appearance), by its grayer under parts and perceptibly longer outermost tail feathers. Like all its congeners, the Arctic Tern is a summer migrant to the British seas and coasts, arriving from the south late in April or early in May. It prefers very similar haunts to those of the preceding species—low rocky islands with sandy or shingly beaches, and with a fair amount of grass and other marine vegetation upon them. It is equally gregarious in its habits, breeding in colonies, and returning regularly to certain districts to rear its young. Its slenderer form, and proportionately longer wings and tail, make it even more elegant looking in the air than its congener. It catches its food in the same Hawk-like or Gannet-like manner, pouncing down into the water and seizing the tiny fish as they swim near the surface. No Tern dives, and it is certainly exceptional for the bird completely to immerse itself; usually it flutters on the surface for a moment, then rises again. Small fish and crustaceans form the principal food of this species. Its note is very similar to that of the preceding Tern—a shrill and monotonouskrick, often prolonged into two syllables.
The nesting season of this Tern begins in June, and fresh eggs may be found throughout that month. Rocky islands seem everywhere to be preferred for nesting places, and the same habit of changing the exact hatching ground prevails in thisas in the preceding species. The Farne Islands are, or used to be, a great breeding station of the Arctic Tern, and there I have taken great numbers of its eggs. The bird probably pairs for life. It differs somewhat in its nesting arrangements from the Common Tern, inasmuch that it never makes any nest. No lining of any kind is placed in the hollow which contains the eggs, and this hollow is generally selected ready made. Another peculiarity is that the eggs are far more generally laid nearer to the water; and this applies not only to the Farne Islands, but to every breeding place of this Tern that I have visited. The two or three eggs are laid in any little depression in the coarse sand or shingle on the line of drift, or amongst small pebbles, or even on the bare ground or rock. These eggs vary from buff to olive, and even pale bluish-green in ground colour, heavily blotched and spotted, especially at the larger end, with dark brown, paler brown, and gray. They are decidedly smaller than those of the Common Tern, more elongated in shape, and are much more olive in general colour. When disturbed from their eggs the Arctic Terns become very noisy, and rise in fluttering crowds above the sacred spot, continuing to fly to and fro, screaming anxiously until the intruder retires.
It is with some hesitation that I include this species, theSterna dougalliof Montagu, in the present work, because if it really does visit our coasts now to breed, it is so exceedingly rare and local, that any ordinary observer of bird life by the sea could scarcely hope to meet with it. It is interesting to remark that the Roseate Tern was first made known to science from a skin that was sent to Montagu, from the Cumbrae Islands, in the Firth of Clyde. It was subsequently found breeding on the Farne Islands by Selby; it formerly bred on the Scilly Islands, as well as on Foulney and Walney; but so far as I can ascertain there is no direct evidence that it breeds at any of these places now. It may be distinguished from the Common Tern by its rosy under plumage; but as this is very apt to fade, a still more infallible distinction, according to Mr. Saunders, is the white inner margin to the primaries.
The Roseate Tern is a very late migrant, not reaching its breeding places until towards the end of May. In its flight and habits generally, it very closely resembles those of the preceding species; but its note is hoarser than that of the Common Tern. The favourite breeding grounds of this Tern appear to be low rocky islets and—so far as our islands are concerned—it is partial to nesting among a larger colony of Arcticor Common Terns. It does not appear to make any nest, but deposits its two or three eggs on the bare ground, usually in a little hollow amongst the shingle. These eggs very closely resemble those of the Common Tern; so closely in fact that no reliable means of distinguishing them can be given.
This species (Sterna minuta) is by far the smallest of the Terns that visit the British coasts in summer to breed. It cannot be said to be anywhere common, and its breeding stations are few and far between. Curiously enough, it is not known to breed on that great resort of British sea fowl, the Farne Islands. There can be no doubt that this Tern is slowly becoming rarer, and in view of this fact I do not feel justified in assisting its extermination, by naming a single locality known to me where it now breeds. The bird-loving reader will, I am sure, appreciate this reticence. Small colonies of this pretty Tern are situated here and there round the British coasts, and in one or two more inland localities. The partiality of the Lesser Tern for the coast of the mainland, rather than for islands, as a nesting ground, contributes largely to the decrease in its numbers. It arrives on our coasts in May, and is readily distinguished from all its congeners by its small size. In its habits it is certainly gregarious, but nowhere are its gatheringsas extensive as in the other common British species. Like its congeners it is eminently a bird of the air, flying up and down in restless uncertain flight, living almost entirely on the wing during the daytime, only seeking the sands or the sea to sleep or to rest. It may be watched flying along the coast, a short distance from land, in a slow irregular way, every now and then poising for a second, and then dropping into the water with a tiny splash to seize a fish or a crustacean. Its note is not quite so harsh as that of the larger species, and may be described as a shrillpirr, most frequently uttered when its breeding places are invaded. Its food is composed of small fish, insects, sand-lice, and crustaceans, most of which is secured whilst the bird is on the wing.
The Lesser Tern begins breeding in June. Like all the other species it returns unfailingly to certain spots along the coast each summer, and may, therefore, be presumed to pair for life. Its favourite breeding-grounds are extensive stretches of sand, varied with slips and banks of coarser shingle. It makes no nest, not even so much as scratching a hollow for its eggs, but lays them on the bare ground. It is most interesting to remark that this Tern never lays its eggs on the fine sand, but always on the bits of rough beach—where the ground is strewn with little stones, broken shells, and otherdébrisof the shore—where their colour harmonises so closely with surrounding objectsthat discovery is difficult. The eggs are from two to four in number—I have on two separate occasions taken clutches of the latter—but three may be given as the average. They vary from buff to grayish-brown in colour, blotched and spotted with various shades of darker brown and gray. During the hottest hours of the day the female sits but little upon them, and it is remarkable how quickly these shore birds will rise from their nests at the first sign of impending danger—the alarm doubtless being given by the male bird from the air above. It is a most exceptional thing to see a conspicuously coloured bird rise from its nest in a bare situation; the eggs are generally coloured protectively, and resemble the objects around them; the presence of the showily attired parent would inevitably lead to their discovery. Early in autumn, when the young are strong upon the wing, the return journey to the winter home on the African coast begins, and it is during these migration journeys that the bird is, perhaps, most commonly observed along the British seaboard.
Allusion may here, perhaps, be permitted to theSterna nigraorHydrochelidon nigraof ornithologists. The Black Tern formerly bred commonly in our marshes and fens, but has long ceased to do so. The “Car Swallow,” as it used to be widelycalled in the fens, belongs to the group known as Marsh Terns—birds that rarely frequent the sea coast at all, so that its absence from our avi-fauna, although greatly to be deplored, could scarcely be remarked by the observer of marine species alone. The White-winged Black Tern and the Whiskered Tern complete this division, known as “Marsh Terns.” Both these latter are occasional wanderers to the British Islands.

In the present chapter we commence the study of an entirely different class of birds. The Gulls are for the most part seen flying in the air or swimming upon the sea, but the Plovers and the Sandpipers spend the greater part of their time on the ground. Again, Gulls, when adult, are remarkably showy birds, but the Plovers and allied species are just as inconspicuous. Many of the haunts frequented by Gulls are utterly unsuited to the Plovers and Sandpipers. These principally delight in low sandy coasts, mud-flats, slob-lands, and salt marshes. Rocks and ranges of cliff have no attraction for these little feathered runners of the shore; they obtain their food on the shallow margin of the sea, on the sand and shingle, themud and the ooze, or at low water among the weed-draped stones. They are emphatically beach birds. Such parts of the coast that have little or no beach uncovered at high water, on which they may rest whilst the tide is turning, or at low water on which they can seek for food, are but little frequented by these Limicoline birds. Consequently we find them much more abundant on the flat eastern coasts of England, and some parts of the southern coasts, with their miles of sand and mud and wide estuaries, than on the much more rock-bound north and west.
The Plovers, with their allied forms, the Sandpipers and Snipes, and between which no very pronounced distinction is known to exist, constitute a well-defined group of birds, perhaps on the one hand most closely allied to the Gulls, and on the other hand to the Bustards. There are more than two hundred species in this group, distributed over most parts of the world. The Limicolæ (under which term we include the Plovers, Sandpipers, and their allies) present considerable diversity in the colour of their plumage, and in a great many species this colour varies to an astonishing degree with the season. The most brilliant hues are assumed just prior to the breeding season; the winter plumage is much less conspicuous. To a great extent this colour is protective, the brighter plumage of summer in many species harmonising with the inland haunts the birds then frequent: theduller hues characteristic of winter assimilating with the barer ground—the sands and mud-flats. It is worthy of remark that the species which do not present this great diversity in their seasonable change of plumage—such as the Snipes and Woodcocks—confine themselves to haunts clothed with vegetation all the year round; or—as in the case of the Ringed Plovers—to bare sands and shingles. In their moulting the Limicolæ are most interesting. It is impossible to enter very fully into the details of this function in the present volume, nor is it necessary, for the purpose of this study of marine bird-life, to do so. A few of the most salient facts, however, may be mentioned. The young of all Limicoline birds are hatched covered with down, and are able to run soon after their breaking from the shell. They consequently spend little time in the nest, after they are hatched. This down varies considerably not only in the pattern of the colour, but in the colour itself. Some of these chicks, or young in down, are beautifully striped or spotted; others are sprinkled or dusted with darker or lighter tints than the general colour. In all, however, the colours are eminently protective ones, and harmonise so closely with the hues of surrounding objects that discovery is difficult; more especially so as the chicks possess the habit of crouching motionless to the ground when menaced by danger. The first plumage of the young bird in the present order, approaches more or less closely in colour that ofthe summer plumage of the adult. At the beginning of autumn, however, these bright colours begin to be changed for a dress which resembles the winter plumage of their parents. This is not effected, however, by a moult, but by a change in colour of the feathers, only the very worn and abraded ones being actually replaced. In the spring following, these immature birds moult into summer plumage, similar to that of the adults, although the wing coverts retain their hue, characteristic of summer or the breeding season, until the next autumn, when for the first time these feathers are changed for the gray or brown ones of winter. It should here be remarked that the wing coverts of the adults seem only to be moulted in the autumn, so that this portion of their plumage is always the same colour after the bird reaches the adult stage of its existence. The phenomenon of the alteration of colour in the plumage of birds, and especially in Limicoline species, without moulting or an absolute change of the feathers, is a profoundly interesting one. One of the most remarkable facts in connection with this phenomenon is the restoration of the worn and ragged margins of the feathers in some Limicoline species to a perfect condition without a change or moult of the notched and damaged feather. Schlegel was the first naturalist, apparently, to discover that this wonderful renovation took place, but his statements seem to have been doubted by naturalists. FortunatelySchlegel’s opinions have been fully confirmed by Herr Gätke; and the reader interested in the subject is referred to that great naturalist’s remarks thereon in his book on the birds of Heligoland.[1]This seasonal change of colour may be produced both by a moult and by actual transition, without cast of feather, even in the same bird: the restoration of ragged feathers and development of colour upon them may also be progressing at the same time. Thus the black markings on the head and neck of the Golden Plover are the result of colour alteration, but the black on the breast is attained by moult. The colour changes in the Sanderling, the Knot, the Dunlin, the Redshank, and numerous other allied birds, are perfectly astonishing: in the Redshank especially so, the profusely barred upper plumage being developed without change of feather, and the feathers reacquiring a pristine freshness and perfectness which seem almost incredible without a complete moult!
Comparatively speaking, the haunts frequented by Limicoline birds during summer, or the season of reproduction, are not, in the strict sense of the term, littoral ones. But few species breed on the actual coast—in our islands they are represented by such birds as the Oyster-catcher and the Ringed Plover; the vast majority rear their young in inland localities, on moors and downs, by the side of rivers, streams, and lakes, in swamps, and so on.As soon, however, as the duties of the year are over great numbers of species resort to the sea coasts, where, in all districts suited to their requirements, they form one of the most characteristic avine features. It is amongst birds of this order that the habit of migration is exceptionally pronounced, some species journeying every year many thousands of miles between their summer haunts, or breeding grounds, and their winter homes, or centres of dispersal. In the present group of birds the wings are generally long and pointed, a form best adapted for prolonged and rapid flight, whilst the legs are usually long—in some species, as, for instance, the Black-winged Stilt, exceptionally so—enabling the birds to wade through shallows and over soft mud and ooze. In some species the feet are semi-webbed, as in the Avocets, in others they are lobed, as in the Phalaropes. The bill varies to an astonishing degree amongst birds of this class, and seems specially modified to meet the varying methods by which food is obtained. Thus we have presented to us the decurved bill of the Curlew type, the recurved bill, characteristic amongst others of the Avocet or the Godwits, the nearly straight bill of such forms as the Oyster-catcher and the Phalarope, hard and chisel-like in the former, and finely pointed in the latter; then, again, the bill in many species is hard and horny, in others it is acutely sensitive, full of delicate nerves, as in the Snipes and many others. The bill of the typicalPlovers differs strikingly from that of the Sandpipers and Snipes, inasmuch that it tapers from the base to the end of the nasal groove, then swells towards the tip. It is utterly impossible in a work like the present, which only attempts a slight sketch of marine bird-life on British coasts, to deal adequately with the astonishing amount of variation, even in this single organ of Limicoline birds. We will, therefore, now proceed to notice the most characteristic species found on the tideways of our islands, either as resident species, as passing migrants, or as winter visitors. It will, perhaps, be most convenient, as well as most interesting, to deal first with those species that are resident on our coasts, as being the most characteristic forms of this group of shore birds.
During summer, this species (theHæmatopus ostralegusof Linnæus and other systematists) south of the Yorkshire and Lancashire coasts, is decidedly local and rare; but north of those localities it becomes one of the most common and characteristic birds of the shore, even extending to the Shetlands, the wildest of the Hebrides and St. Kilda. It is of interest to remark that in some parts of Scotland the Oyster-catcher drops its marine habits, and frequents the banks of rivers and lochs. There is, perhaps, no more conspicuous, no more handsome, no more noisy bird along the coast, than the Oyster-catcher.It is worthily named “Sea Pie,” its strongly contrasted black and white plumage recalling at once the Magpie of the inland fields and woods. The favourite haunts of this species are long stretches of low, rocky coast, relieved here and there by patches of shingle and long reaches of sand, broken with quiet bays, creeks, and lochs, where a large amount of beach is exposed at low water. One may generally find an Oyster-catcher about rocky islands; it is also very partial to resting on these, between the tides. Few birds look daintier or prettier than the present species, as it stands motionless on some weed-grown rock, its pied plumage, rich orange-coloured bill, and flesh-pink legs, coming out boldly against the olive-green masses of algæ. It is not often, however, that we can approach sufficiently close to see such details; as a rule the bird rises piping shrilly into the air, before it is actually seen, and long before unaided vision can distinguish colours distinctly. During summer the Oyster-catcher can scarcely be regarded as gregarious, but in winter, when its numbers are increased by migrants from the north, flocks of varying size may be met with. When flushed, the flight of this bird is very erratic and very rapid, performed by quick and regular strokes of the long-pointed wings; and perhaps it is now that the colours of the bird are seen to best advantage. The call note is heard most frequently and persistently as the bird hurries away in alarm, orcareers about the air overhead, anxious for the safety of its eggs or young. This note cannot readily be confused with that of any other bird upon the coast. It may best be described as a loud shrillheep-heep-heep. The food of the Oyster-catcher is composed of mussels, whelks, limpets, crustaceans, and small fish, together with various tender buds and shoots of marine plants. Its chisel-shaped bill enables it readily to detach limpets from the rocks, or force open the closed valves of the mussel or the cockle. Oyster-catchers often frequent certain spots on the coast to feed, visiting them as soon as the tide admits, with great regularity. It may here be remarked that this bird wades often through the shallows, but never swims, as far as I know, unless wounded.
The eggs of the Oyster-catcher are laid in May or June, in the north a little later than in the south. The nesting-place is usually a stretch of rough pebbles or a shingly beach in some quiet bay, a low rocky island, or even a stack of rocks. Although Oyster-catchers cannot be said to breed in colonies, like some of the Gulls and Terns, numbers of nests may be found at no great distance apart. The nest is simple in the extreme—a mere hollow, in and round which are neatly arranged flat pebbles and bits of broken shells. As a rule, several mock nests may be found near to the one containing the eggs. These eggs are usually three in number, but sometimes four, pale buff orbrownish-buff in ground colour, blotched, spotted, and streaked with blackish-brown and gray. Two distinct types are noticeable: one in which the markings are streaky, and often form a zone; the other in which they are large, irregular, and distributed over most of the surface. As soon as the nest is approached the ever-watchful birds rise screaming into the air, and should many pairs be breeding in company, the din soon becomes general and deafening. It is under these circumstances alone that the Oyster-catcher permits man to approach it closely; at all other times it is certainly one of the shyest and wariest of birds on the coast.
With the present species—or resident large race, theÆgialitis hiaticula majorof Tristram, as we should more correctly describe it—we reach the true Plovers. The Ringed Plover is one of the most widely distributed of our coast birds, frequenting all the flat sandy shores of the British Islands, from the Shetlands, in the north, to the Channel Islands, in the south. And not only does it haunt the coast, but it is found on the banks of rivers and lochs in many inland districts. In many places this species is known as the “Ring Dotterel”; in others its local name is the “Sand Lark.” The favourite haunts of the Ringed Plover are the sandy portions of the beach; but in autumn and winter this bird frequently visitsmud-flats. The Ringed Plover is about the size of a Thrush, and may be easily recognised by its broad white collar, black breast and cheeks, brown upper parts, and snow-white under parts. Its actions on the shore are most engaging, tripping here and there along the margin of the waves, over the wet sand and shingle, darting this way and that as some tempting morsel of food is discovered. If in autumn or winter, this Plover will generally be met with in flocks of varying size; if in summer in scattered pairs or parties composed of the birds breeding in the immediate neighbourhood. Ringed Plovers are most attached to certain haunts, and seem to frequent them year by year, notwithstanding continued persecution and disturbance. It is the same when they are feeding. If alarmed they usually rise in a compact bunch, fly out to sea a little way, then return inshore, perhaps passing two or three times up and down before finally alighting. Again and again may this action be repeated, although the flock has a tendency to break up if flushed many times in quick succession, and odd birds will fall out, or remain skulking amongst the shingle. A dense flock or bunch of Ringed Plovers is a pretty sight. The birds fly quickly, and wheel and turn with astonishing precision, now close to the waves, then up in the air above the horizon, often persistently uttering their shrill call note, which resembles the syllablestoo-itrapidly repeated. Occasionally afair sprinkling of Sanderlings and Dunlins may be observed in the flocks of this species. If seriously alarmed the entire flock will mount up high, and go off to a distant part of the coast, or even divide into several smaller ones, each retiring to a different spot; but almost invariably they return, and reform into a single company on the old familiar sands, within a hour or so of their scattered departure. The food of this pretty little Plover consists of the smaller creatures of the shore, such as minute sand-worms, shrimps, sand-hoppers, tiny molluscs, and insects. That this species occasionally eats vegetable substances I have assured myself by repeated dissection.
Although the Ringed Plover appears only to rear one brood in the year, its laying season is prolonged from the middle of April to the beginning of June. Early in April the winter flocks begin to disband, and the birds to disperse over their breeding places. Many pairs may be found breeding on one large stretch of sand in a suitable district. Some individuals seek an inland site for their eggs, on the bank of a stream or lake, but the majority prefer the sands of the sea-shore. Occasionally the nest has been discovered remote from water. This Plover makes no nest. The eggs sometimes are laid in a hollow of the sand, but just as frequently on the level surface. The fine sand is always preferred to the shingle, as the eggs best harmonize in appearance with it, their finemarkings becoming more conspicuous on the coarser surface. The bird sits lightly: indeed it is most exceptional to see one rise from its eggs, unless the spot had been previously marked. When disturbed, the birds exhibit but little outward manifestation of alarm. They may be seen running to and fro about the sand, but their behaviour is very different from that of the Lesser Terns, which often nest on the same sands. The eggs of the Ringed Plover are always four in number, very pyriform in shape, and invariably laid with the pointed ends turned inwards. They are large in proportion to the bird, and pale buff or stone colour sparingly spotted and speckled with blackish-brown and ink-gray. During May and June a smaller and darker race of Ringed Plover passes along our coasts, to breed further north; appearing on the return journey during August, September, and October. There is some evidence to suggest that this race breeds sparingly on the coasts of Kent and Sussex.
This species, theÆgialitis cantianaof ornithologists, is one of the most local of British birds. Stragglers have been obtained here and there along the coast line between Yorkshire and Cornwall, but its only known nesting places are on certain parts of the coasts of Kent and Sussex. It is now nearly a century ago since this Plover was first made known to science by Lewin, who figuredit in hisBirds of Great Britain; and by Latham, who described and named it in the supplement to his great work, theIndex Ornithologicus, from examples which had been obtained on the Kentish shingles by Mr. Boys of Sandwich. The Kentish Plover bears a superficial resemblance to the Ringed Plover, but may readily be distinguished by the broken pectoral band, represented by a dark patch on each side of the breast, and the reddish-brown nape and crown. Unlike the preceding species, this Plover is a summer migrant only to the British coasts, arriving towards the end of April or early in May, and departing again with its young in August or September. Odd birds, however, have been met with during winter. The Kentish Plover does not differ in its habits in any marked degree from the Ringed Plover, and frequents very similar localities, stretches of sand and shingle. Like that bird, it also gathers into small parties during summer; but in our islands, where its numbers are limited, we more usually find it in isolated pairs on various suitable parts of the shore. It possesses the same restless habits; running about the wet shining sands and shingles close to the breaking waves, in quest of the sand-hoppers, crustaceans, worms, and other small marine creatures on which it feeds. It cannot be regarded as a shy bird, permitting a somewhat close approach, and manifesting little fear or alarm even when its breeding grounds are invaded by man. Itsalarm note may be described as a shrillptirr, but the usual call is a clear loudwhit, which, during the love season, is frequently uttered so quickly as to form a sort of trill, as the cock bird soars and flies round and round above his mate. The Ringed Plover utters a very similar trill during the pairing season.
The Kentish Plover rears but one brood during the summer, and preparations are made for this towards the end of May. It is not improbable that this Plover pairs for life, seeing that the same localities are visited year by year for nesting purposes. It makes no nest, the eggs being laid in a little hollow amongst the coarser sand or the shingle, or on a drift of dry seaweed and other shoredébris. The eggs are usually three, but occasionally four in number, and are pale or dark buff in ground colour, blotched, scratched, and spotted with blackish-brown and slate-gray. As is the almost invariable custom with birds breeding on bare plains and beaches—and whose eggs are protectively coloured—the Kentish Plover sits lightly, rises from her eggs as soon as danger is discovered, and evinces but little outward anxiety for their safety; although, in some instances, the feigning of lameness has been resorted to, especially when the eggs have been on the point of hatching. The young birds and their parents form a family party during the autumn, and apparently migrate southwards in close company.
With the present species we exhaust the number of Limicoline birds that nest upon the shore in the British Islands. All the other species that make our sands and mud-flats their winter home, or their place of call during their spring and autumn migrations, breed away from the actual beach on marshes and moors and uplands, or do not rear their young at all within our area. Closely associated with most of these birds are the fascinating problems of Migration. We miss the feathered hosts from sand and mud-flat as the spring advances; we note the fleeting appearance of others along the shore bound to far away northern haunts: and then long before the first faint signs of autumn are apparent these migrant birds begin to return, and imbue the wild lone slob-lands and shingles with life. To and fro with each recurring spring and autumn, the stream of avine life flows and ebbs; by day and by night the feathery tides press on, calling forth wonder from the least observant, filling more thoughtful minds with the complexity and the mystery of it all. We have not space to deal here with this grand avine movement; but, content with this passing allusion to it, pass on to a study of the other feathered dwellers by the sea. (Conf.p.281).
It is rather remarkable how few species of Limicoline birds breed on the British coast-line. Not a single Sandpiper nor Snipe does so, and but two or three Plovers, as we have already seen. So far as summer is concerned, these wading birdscannot be regarded as a very remarkable feature of avine life upon the coast; and it is, doubtless, because they are so little known to the majority of seaside visitors, that they appeal so much less to the popular mind than the more ubiquitous Gulls. But from September onwards to the following spring, Plovers and Sandpipers are the most prominent characteristics of all the more low-lying coasts. We will briefly glance at those species that not only frequent such situations regularly every season, but occur in sufficient numbers to place them beyond the category of abnormal visitors, or storm-driven wanderers from their natural haunts.
This species, theCharadrius pluvialisof ornithologists, is, from the regularity of its appearance and its great abundance, known almost everywhere asthePlover of the coast. It derives its trivial name from the profusion of golden yellow drop-like spots which adorn its upper plumage, and may always be distinguished from allied species by its barred tail feathers and white axillaries. Large flights of Golden Plover begin to appear on our low-lying coasts in September, and through October and November the number steadily increases. Many of these birds simply pass along our shore-line to haunts in the Mediterranean basin, but many linger thereon through the winter. One of the great haunts of this Plover is along the shoresof the Wash—that vast area of mud, and sand, and salt-marsh, which extends for miles in drear monotony, only enlivened and made endurable by the hordes of wild fowl that congregate upon its treacherous surface. Here, at the end of October, or during the first week in November, the migration of the Golden Plover can be observed in all its strength. Day after day, night after night, I have remarked the passage of this bird, in almost one unbroken stream, flock succeeding flock, so quickly as to form a nearly continuous throng. Upon the sands this Plover often associates with Dunlins, Gray Plovers, Lapwings, and other waders. Great numbers are, or used to be, shot or netted in this district, and sent to inland markets, for their flesh is justly esteemed for its delicacy, ranked by some as second only to that of the Woodcock. Golden Plovers feed and move about a good deal at night, especially by moonlight. Their food, during winter at least, consists of sand-worms and hoppers, molluscs, small seeds, and so on. The whistle of this Plover is one of the most attractive sounds of the mud-flats and salt-marshes. It may, under suitable atmospheric conditions, be heard for a long distance across the wastes, and sounds something likeklee-wee, occasionally prolonged intoklee-ee-wee. This note is uttered both while the bird is on the ground and in the air. In the pairing season it is run out into a trill. The movements of the Golden Plover during winterare largely regulated by the weather, and I have known it desert a district entirely, or become very restless and unsettled, just previous to a storm.
In spring the sea coasts are deserted, and the Golden Plover retires to its breeding-grounds. These, in our islands, are situated on the upland moors and mountain plateaux. The nest, invariably made upon the ground, is often placed on a hassock of coarse herbage, or on a tuft of cotton grass, and consists merely of a hollow, lined with a few bits of withered grass or dead leaves. The eggs are four in number, buff blotched and spotted with various shades of brown, and more sparingly with gray. They are much richer and yellower in appearance than those of the Lapwing, otherwise closely resemble them.
This handsome bird, generically separated by many ornithologists from the preceding, on account of its possessing a minute and entirely functionless hind toe, is theVanellus helveticusof Brisson, and theCharadrius helveticusof writers who ignore the genusSquatarola, founded by Leach on the above-named trivial and, all things considered, utterly inadequate character. The Gray Plover is the first species we have considered in the present work that does not breed in the British Islands. Many birds of this species only pass our coast on migration in going to, and returning from, their Arctic breeding-grounds,but a fair number linger upon them throughout the winter. The Gray Plover may be readily distinguished from the preceding, as well as from all other allied forms, by the presence of a rudimentary hind toe, and by itsblackaxillaries. In its seasonal changes of plumage it closely resembles its ally. In the adult plumage, however, it never exhibits any of the yellow, drop-like, spots on the upper parts, so characteristic of that bird in every feather stage of its existence. Gray Plovers begin to arrive on the British coasts as early as August, and the migration continues with increasing strength until October or November. Such individuals as pass our islands for more southern haunts return along the British coasts during May and June. During its sojourn with us, the Gray Plover confines itself almost entirely to the mud-flats and salt marshes. It does not gather into such large companies as the Golden Plover—but this may be due, perhaps, to its smaller numbers—and is often seen in pairs or small parties, whilst odd birds will occasionally attach themselves to flocks of Knots and Dunlins. In its habits generally, in its flight, and in its food, it closely resembles its commoner and better known ally. The note uttered whilst the bird lives upon our coasts resembles that of the Golden Plover.
The breeding-grounds of the Gray Plover are on the tundras and barren grounds in the Arctic regions of the Old and New Worlds, above the limits offorest growth. The nest is always made upon the ground, and is merely a slight hollow, lined with a few scraps of withered herbage. The four eggs very closely resemble those of the Lapwing, but are not quite so olive. When once flushed from the nest the Gray Plover becomes very wary and restless, and does not return for some time; should the young be hatched various alluring antics are indulged in to withdraw attention from them.
This bird is the typical species of Brisson’s genusVanellus, and is known to most naturalists asVanellus cristatusorvulgaris. It cannot easily be confused with any other British bird, and is readily identified by its long conspicuous crest, metallic green, suffused with purple upper parts, and bright chestnut upper and under tail coverts. Further, its appearance in the air, so far as British Limicoline birds are concerned, is unique; the curiously rounded wings, and deliberate Heron-like flight, together with the peculiar note, make the matter of its identification easy to the veriest tyro in ornithology. The Lapwing is also not only the commonest of its order found in Britain, but certainly the most widely dispersed. Nevertheless, it is only during the non-breeding season that the Lapwing can fairly be described as a marine bird. From March onwards to the early autumn it retires to inland moors, pastures, and rough undrainedlands to breed, returning coastwards again when the young are reared, especially from the more exposed and elevated localities. The favourite marine haunts of the “Green Plover,” or Peewit, as this bird is otherwise called, are rough saltings, mud-flats, and slob-lands; sands and shingles it rarely visits unless when driven to do so by heavy snowfalls; and at all times it prefers ground overgrown with herbage to the bare beaches. As this species presents little difference between summer and winter plumage, means for concealment may have some influence in its choice of haunt. When standing or running on the ground the Lapwing is a very ordinary looking bird; graceful enough, it is true; but the moment it rises into the air the observer is struck with the singularity of its appearance; the broad and rounded wings are unfolded and moved in a slow flapping Owl-like manner; very often grotesque evolutions are indulged in, the bird rising and swooping down again, turning and twisting in a most erratic way, and all the time persistently uttering the wild, mewing, plaintive cry that is absolutely characteristic of this Plover—an unmistakable and unique note among birds. It may be expressed on paper as a nasalpee-weet, frequently modulated intoweet-a-weet,pee-weet-weet.
As the autumn days draw on the Lapwing becomes more gregarious, often forming into flocks of enormous size, which wander about a good deal as the varying weather affects their supply of food.This, in winter, consists chiefly of worms, grubs, molluscs, crustaceans, and other small marine creatures; in summer, seeds, shoots of herbage, and various ground fruits and berries are added. The Lapwing in its movements on the ground is light and elegant, running and walking well, standing high upon its legs, but it seldom seems to wade, and never, so far as I know, attempts to swim under any normal circumstances. Great numbers of Lapwings are killed for the table, but the flesh cannot be compared with that of the Golden Plover, being not only dark in appearance, but unpleasant in taste, especially after the birds have resided long in littoral haunts.
The Lapwing at the approach of spring retires inland to breed, visiting for the purpose moors, rough lands, water meadows, pastures, and grain fields. The nesting habits of this species are certainly better known than those of any other member of the Plover tribe, at least, as far as British birds are concerned. Every person at all familiar with the common objects of the country, knows the nest of the Lapwing, and must time and again have been amused with the bird’s erratic behaviour, as its breeding grounds are invaded by human intruders. The nest is always made upon the ground, generally in a hollow of some kind, often in the footprints of cattle and horses. Sometimes it is cunningly hidden beneath a tuft of rushes or hassock of sedge and grass; whilst thesummit of a mole-hill is not rarely chosen. The hollow is lined with a few bits of the dry and withered surrounding herbage; and in many cases even this slight provision is omitted. The four eggs (five have been recorded!) very like pears in shape, are buffish-brown or pale olive in ground colour, handsomely blotched and spotted, especially on the larger half, with blackish-brown, paler brown, and gray. If the flesh of the Lapwing is not held in very high repute its eggs make ample amends for the deficiency. Vast numbers are systematically gathered for the table; and as the birds will replace their stolen eggs again and again, the harvest may be prolonged over several weeks. The first eggs are laid in April; in more northern localities not before May. In the early days of the Plover egg season, these commodities frequently realise as much as twelve shillings per dozen, and are a source of profit to many a dweller in country districts. Dogs are sometimes trained to search for them. When the young are hatched the Lapwing displays many curious tricks to lure enemies from them, feigning death or broken wings, or swooping with loud cries to and fro.
It is rather a remarkable fact that this species, theStrepsilas interpresof naturalists, does not breed in the British Islands. Some naturalists have suspected that it does so on the Hebrides,and it has been said to nest on the Channel Islands, but no direct proof has yet been obtained. Under exceptional circumstances the Turnstone may be met with inland, especially during the season of its migrations, but otherwise it is strictly a coast-bird, as much so as the Oyster-catcher, and rears its young upon the shore. This somewhat singular bird is met with on the British coasts, most commonly during its passage north or south, comparatively few individuals remaining upon them for the winter. The Turnstone cannot readily be confused with any other coast bird, its mottled black and chestnut upper parts, black throat and breast, and white belly, being very distinctive. The wings and tail during flight exhibit a good deal of white upon them. Turnstones, chiefly young birds, begin to arrive on the British coasts at the end of July, and the migration of the species continues through August and September; the return passage in spring may be remarked towards the end of April, and lasts for about a month. Mud-flats, slob-lands, and salt-marshes are not frequented much by the Turnstone; it always prefers the low rocky coasts, and seems specially fond of haunting rocks and islands. Social to a great extent in summer, in winter this bird is more or less gregarious; but many odd individuals attach themselves to parties of other shore-frequenting species. An example now lying before me was shot from the company of Common Sandpipers. The Turnstone is a restlesslittle creature, ever on the run in quest of food. It may be watched hunting about the beaches, or running amongst pebbles, and over the piles of drifted rubbish that the tide washes up in a long irregular line along the shore. In watching the actions of this bird, the observer cannot fail to remark its singular habit of turning over shells and other objects, in quest of the small marine creatures that lurk under them, with its conical shaped beak, and perhaps occasionally with its breast as well. This peculiarity has gained for the Turnstone its trivial name. Not only does it run about the sand and rocks, but it frequently wades, and has even been seen to swim just outside the line of breakers, rising from time to time, flying a little way and then settling upon the water again. The flight of this bird is not very rapid, and generally taken close to the ground; its note is a shrill whistle, resembling the syllablekeet. During the love season this note is run into a rapid trill. The food of the Turnstone is composed of sand-worms, crustaceans, molluscs, and other small marine animals.
The Turnstone changes its haunts but little during the breeding season. It rears its young on the beaches or on rocky islets, placing its nest amongst the scanty marine herbage, beneath the shelter of a tuft of grass or a little bush. This is merely a hollow lined with a few bits of dry grass or other vegetation. The four eggs are olive-greenor pale buff in ground colour, blotched, spotted, and clouded with olive-brown, dark reddish-brown, and violet-gray. But one brood is reared in the year, and the eggs are laid in June. As soon as the young are able to fly the movement south begins. The Turnstone breeds throughout the northern parts of the Nearctic and Palæarctic regions, as far as land is known to extend. Its nearest breeding stations to the British Islands are in Denmark, on some of the Baltic Islands, and in Iceland. During winter it visits the coasts of almost every part of the world, south of the Arctic circle.
But three species of the genusPhalaropusare known, and two of these are British birds, one of them the Red-necked Phalarope,P. hyperboreus, breeding very sparingly and locally within our limits, the other the Gray Phalarope,P. fulicarius, a more or less regular visitor to our coasts in autumn and winter. From many points of view the Phalaropes are very interesting birds. They are distinguished from all other Limicoline forms by the structure of the feet, which are lobed like those of the Coot—a peculiarity which induced Edwards, in 1741, to describe a Phalarope as the “Coot-footed Tringa.” They are by far the most aquatic of the Charadriidæ, swimming as readily as Gulls or Ducks, and often going for hundreds of miles out on to the open sea; indeed they spendmost of their time upon the water, only visiting land for any lengthened period during the breeding season.
There can be little doubt that the Gray Phalarope is a more abundant visitor to British waters, in autumn and winter, than is generally supposed. It has little reason to visit land at all at such a season, unless driven towards it by exceptionally severe weather. Occasionally, however, this Phalarope has occurred on our coasts in great numbers, something similar to the visitations of Sand Grouse, with which doubtless most readers are familiar. The autumn of 1866 is specially famous for a great “rush” of Gray Phalaropes to the British seas and coasts, and it is estimated that upwards of 500 were caught, of which large number nearly half occurred in Sussex! The most recent irruption of Gray Phalaropes was in 1886. The Gray Phalarope lives almost entirely out at sea, after the breeding season is over, wandering immense distances from land, and even accompanying whales, for the sake of catching the various small marine creatures disturbed by the “blowing” of those mighty animals—hence to the sailor it is often known as the “Whale Bird.” So hardy is this little bird, that it has been watched swimming about amongst icebergs far from land. It swims lightly and buoyantly as a foam fleck, with a peculiar bobbing motion of the head, but it is not known to dive. It apparently flies withreluctance, always preferring to swim out of danger. Its food principally consists of insects, but crustaceans, worms, and scraps of vegetable substances are eaten. The call note of this Phalarope is described as a shrillweet, and the alarm note, heard most frequently during flight, as a rapidly repeatedbick-abick-a.
The Gray Phalarope is not known to breed anywhere on continental Europe, but does so in Spitzbergen, in Iceland, Greenland, and probably throughout all suitable parts of Arctic America and Asia, as far north as land extends. In winter it is very widely dispersed, even wandering as far as New Zealand. The Gray Phalarope is one of those species that change greatly in the colour of their plumage according to season. In winter dress—the plumage perhaps most familiar to British observers—the back is gray, and the under parts pure white; but in summer the whole of the latter are rich bright bay, and the feathers of the upper parts are dark brown with pale reddish-brown margins. In this plumage it is known as the Red Phalarope. Another interesting fact is that the female is much more brightly and richly coloured than the male, and the latter not only performs the duty of incubating the eggs, but takes the greater share in tending upon the young! It may thus be inferred that the pairing habits of this Phalarope are most singular, the female conducting the courtship! The Gray Phalaroperemains practically gregarious throughout the year, breeding in colonies of varying size. Its favourite nesting-places are beside the marshy pools and lakes on the tundras, at no great distance from the Arctic Ocean. The nest is made upon the ground, and consists of a mere hollow in the moss or lichen, lined with a few dry leaves and grasses. The four pyriform eggs are pale buff, tinged with olive, blotched and spotted with dark brown and paler brown. At the nest the old Phalaropes are remarkably tame and confiding, showing little fear of man, but when the young are hatched often trying to delude him away by various deceptive antics. As soon as the young are sufficiently matured, the nesting-places are deserted, and young and old repair to the sea for the remainder of the year.
The second British species, the Red-necked Phalarope, is scarcely less known to the majority of people than the Gray Phalarope. It seldom visits the land except for breeding purposes, and as its nesting-places in our area are not only few, but in the remotest part of it, opportunities for observing its habits are few and fitful. It is a summer visitor to certain parts of the Outer Hebrides, to the Orkneys, and the Shetlands. Outside our limits its range is very extensive. It breeds in suitable localities throughout the Arctic regions of the New and Old Worlds, above the limits of forest growth; in winter it wanders far southwards, andis then found on the coasts of Europe, Southern Asia, Mexico, and Central America. Like the preceding species it is thoroughly marine in its choice of a haunt, but does not appear to wander for such great distances from land. It is just as tame and confiding, just as social in summer, and as gregarious in winter. It swims equally as well and buoyantly, with the same peculiar bobbing motion; whilst on the land it is able to run and walk with ease. It exhibits the same reluctance to take wing, preferring to retreat from danger by swimming, although it flies on occasion quickly and well. Its food is very similar, and its note is a shrill but rather lowweet. As Professor Newton has remarked, both this and the preceding species of Phalarope are entrancingly interesting in their habits. “Their graceful form, their lively colouration, and the confidence with which both are familiarly displayed in their breeding-quarters can hardly be exaggerated, and it is equally a delightful sight to watch these birds gathering their food in the high-running surf, or, when that is done, peacefully floating outside the breakers.”[2]
So far as concerns Scotland, the breeding season of the Red-necked Phalarope commences in May, but in more Arctic localities it is deferred until several weeks later. It returns with unerring regularity to the old accustomed spots to rearits young. These are on the marshy moors, beside the pools, at no great distance from the sea. The nest, usually made on the ground, (in the valley of the Petchora it has been found in a hassock of coarse grass a foot or more above it), is a mere hollow lined with a few scraps of dead grass and rush. The four eggs are buff of various shades, or pale olive, spotted and blotched with amber and blackish-brown, pale brown and gray. As previously remarked the male bird incubates them. When disturbed at its breeding grounds, the Red-necked Phalarope slips off the nest and takes refuge in the water, manifesting little concern for its safety. As soon as the young are sufficiently matured, they and their parents resort to the sea, moving southwards as autumn advances, and for the most part keeping to the water until another nesting season comes round.
This species, (Numenius arquata), is not only the largest Limicoline bird that frequents the coast, but also one of the best known. There are few parts of the shore during autumn and winter where an odd Curlew cannot be found, whilst in some localities it may be classed as absolutely common. The Curlew is another of those species that present little difference between summer and winter plumage, and yet the haunts it selects in summer differ very considerably from those itseeks in winter. It is a resident in the British Islands, but its numbers are very considerably increased in autumn, by migrants from more northern latitudes. It may be found, as previously inferred, on almost all parts of the shore, but such beaches where wide expanses of sand, mud, and broken rocks occur, are specially preferred—as are also salt-marshes and wet meadows close to the sea. Of all wild fowl the Curlew is one of the wariest, never allowing a close approach unless stalked with the greatest care, or surprised in some unusual way, which does not often happen. In some districts where little beach is exposed during high-water, the Curlews will retire some distance inland, but return with remarkable punctuality as soon as the tide begins to ebb. Shingle banks and islands are also often visited between tides. Curlews when feeding are very restless birds, running and walking about the beach, seemingly in a very careless and unsuspecting manner, but sentinels are ever on the watch to sound the warning note, which sends the big long-billed speckled birds hurrying away to safer haunts. The Curlew feeds both by day and by night; and its wild somewhat mournful note, shrill and far-sounding,curlee,cur-lee, may repeatedly be heard during darkness. The flight of this bird is both rapid and well sustained. Gätke, on evidence which seems absolutely conclusive,estimates its speed on certain occasions to be not less than a mile a minute, and possibly very much more! Although the Curlew repeatedly wades, it is not known to swim under normal circumstances, but has occasionally been seen to perch in a tree. All through the autumn and winter the Curlew continues gregarious. It migrates in vast flocks, and frequently associates with other wild fowl, although it may be that these other and smaller species seek its company to profit by its extraordinary vigilance. Sand-worms, crustaceans, and molluscs form its principal food whilst living on the coast, but in summer, at its breeding-grounds, worms, grubs, insects, ground fruits, and berries are eaten. The European form of the Curlew is pretty generally distributed over the western half of the Palæarctic region, and in winter is found throughout Africa.
The Curlew begins to leave the coast for more or less inland haunts in March, scattering over most of our swampy moorlands and rough higher grounds to breed. The eggs are laid during April and May. The nest is invariably made upon the ground, and consists merely of a shallow cavity, lined with a few bits of withered herbage or dead leaves. Numbers of pairs often nest within a comparatively small area of suitable ground, and should one pair be disturbed, the entire community is soon thrown into a state of alarm. The four eggs of the Curlew vary from olive-green to buff,blotched and spotted with olive-brown and pale gray. The Curlew begins to wander coastwards as soon as the young are reared. By far the majority seen first are young birds, and these arrive from the middle of July onwards.
This species—which is theNumenius phæopusof systematists—is best known on the British coasts during its annual migrations, passing our islands so regularly that it has received the name of “May Bird.” On the Lincolnshire coast, as well as in many other districts, the Whimbrel is almost universally known as the “Jack-Curlew.” During its seasonal movements it visits most parts of the British coast-line, but mud-flats, salt-marshes, estuaries, and extensive reaches of sand, are the most favoured localities. Its habits are very similar to those of the Curlew—a bird which it somewhat closely resembles in general appearance, although it is much smaller. It is also a less wary bird, especially upon its arrival; much stalking, however, soon teaches it shyness. Perhaps the Whimbrel is not so often seen on the actual beach as the Curlew; it seems to prefer to resort to slob-lands, and swampy meadows adjoining the beach. It not only wades, but is said even to swim occasionally, and is fond of bathing, throwing the water over itself as it stands breast-high in the sea. In autumn and winter the Whimbrel iscertainly gregarious, but its gatherings are never so large on our coasts as those of the Curlew. This, however, is entirely due to local causes, for Gätke reports that on the bright warm days of April and May they pass over Heligoland in successive flocks, at a vast height, and flying at a tremendous speed. On migration the note of the Whimbrel may be described as a shrillhee-hee-hee. Its food, during its sojourn in small numbers on the British coasts, consists principally of crustaceans, sand-worms, and molluscs.
The Whimbrel is a later breeder than the Curlew. During the nesting season it is one of the most local of our birds, and is only known to nest on North Ronay—one of the Hebrides—the Orkneys, and the Shetlands. Its favourite breeding-grounds are the wild moors, at no great distance from the sea. Although not gregarious during summer, many pairs often nest on the same portion of the moors. The nest is made upon the ground, sometimes amongst heather, or beneath the shelter of a tuft of grass, and consists of a few bits of withered herbage, arranged carelessly in some slight hollow. The four eggs are very like those of the Curlew, but are much smaller. The bird’s actions at the nest are very similar to those of the preceding species. Outside the British limits, the breeding range of the typical Whimbrel reaches from Iceland and the Faröes, across Arctic Europe, whilst its winter home is in Africa.
