Family

Description

6-7" (15-18 cm). Sparrow-sized. Olive-green above, paler below, with yellowish tinge on back, flanks, and undertail coverts; dull gray crown; whitish eyebrow. Eye red. Similar to Red-eyed Vireo, but much yellower below, and with more indistinct markings on head.

Voice

A series of deliberate, musical phrases, more widely spaced than in song of Red-eyed Vireo.

Habitat

Streamside thickets and woodlands.

Range

Breeds from Rio Grande Valley of Texas southward. Winters in tropics.

Discussion

The Yellow-green Vireo is one of the tropical members of the group of species that includes our familiar Red-eyed Vireo. Like the Red-eyed, this bird obtains its food by searching rather carefully in the foliage of trees, without the more active motions of warblers. Its song is repeated monotonously throughout the day.

Nesting

3 or 4 white eggs, lightly spotted with brown, in a pendant cup of plant fibers and bark strips, bound together with spiderweb and suspended from a forked branch in a bush or small sapling.
