THE YELLOW-THROATED FLYCATCHER, OR VIREO.

THE YELLOW-THROATED FLYCATCHER, OR VIREO.Vireo flavifrons,Vieill.PLATE CXIX. Male.While the small White-eyed Vireo rambles among the low bushes and brambles of the fields of all parts of the United States, the Yellow-throated species takes possession of the forest, and gleans with equal ease among the branches of the tallest trees, to which it seems to give a marked preference during the spring and summer. It is fond of the quietest solitudes, and in its habits is nearly allied to the Red-eyed Vireo. Like it also, it is a slow, careful, and industrious bird, never imitating the petulant, infantile, and original (if I may so speak) freaks of its gay relative, the White-eyed. It is more silent than either of the species above mentioned, although its notes have a strong resemblance to those of the Red-eyed. These notes are more measured and plaintive than those of any of its tribe, sometimes consisting of sounds resembling the syllablesprēe-ā, preē-ā, rising and falling in sweet modulation. One might imagine them the notes of a bird lost in the woods, and they make a strong impression on the mind of the listener. Now and then the sight of his mate seems to animate the male, when he repeats the same syllables eight or ten times in succession. When sitting pensively on a twig, as if waiting for an invitation to sing, it utters a kind of whining sound, and in autumn, as well as during its retrograde march towards the south, it becomes quite silent.When searching for food, it ascends the branches of trees by regular short hops, examining with care every leaf and bud in its way, never leaving a branch for another until it is quite assured that nothing remains on it. When flying to some distance, its motions, although quick, are irregular, and it passes among the boughs at a moderate height.This species is at all times extremely rare in Louisiana, where I have seen it only during early spring or late in the autumn. My friend BACHMAN, has never observed it in South Carolina. Indeed, it is only from Pennsylvania eastward that it is met with in any quantity. During summer it feeds entirely on insects, devouring with equal pleasure caterpillars, small moths, wasps, and wild bees. The summer over, it rangesamong the low bushes in search of berries, accompanied by its young, and at that time enters the orchards and gardens even of our villages and cities. It arrives in Pennsylvania and New Jersey about the end of April, and in Massachusetts and Maine about a month later.The nest of the Yellow-throated Vireo is truly a beautiful fabric. It sometimes extends to five or six inches in depth, and as it is always placed at the extremity of small twigs, it is very conspicuous. It is attached to these twigs with much care by slender threads of vines, or those of other trees at its upper edges, mixed with the silk of different caterpillars, and enclosed with lichens, so neatly attached by means of saliva, that the whole outer surface seems formed of them, while the inner bed, which is about two and a half inches in diameter, by an inch and a half in depth, is lined with delicate grasses, between which and the bottom coarser materials, are employed to fill the space, such as bits of hornets' nests, dry leaves, and wool. The eggs, which are four or five in number, are of an elongated form, white, spotted with reddish-brown or black. The young are out about the beginning of July. In Maine it raises one brood only, but farther south not unfrequently two.Vireo flavifrons,Ch. Bonaparte, Synops. of Birds of the United States, p. 70.Yellow-throated Flycatcher,Wils.Amer.

It seldom grows beyond the size of a bush. The blossoms are lasting, and although without odour, are pleasing to the eye, on account of their pure white colour when first expanded; they dry on the stalks, retaining their form, and remaining until winter. The species is characterized by its oblong, deeply sinuate leaves, which are downy beneath, and its radiated loosely thyrsiform cymes.
