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 syllables pree-d, pree-d, 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 ranges
