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


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.


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.
