About These Birds
Bell's Vireo
Bell's Vireo is a small, active vireo of riparian thickets and brushy areas in the western and central United States, wintering in Mexico and Central America. It has plain olive-grey plumage with faint wing bars and a persistent, complex song delivered continuously throughout the breeding season. Some subspecies, like the Least Bell's Vireo, are federally endangered due to cowbird parasitism and riparian habitat loss.
