About These Birds
Black-capped Vireo
The Black-capped Vireo is a Near Threatened small vireo of Texas and Oklahoma in the United States, wintering on Mexico's Pacific coast, with males displaying a striking black cap, white spectacles, and olive-green and white plumage. It inhabits dense, shrubby oak and juniper thickets in rocky terrain. Brown-headed cowbird parasitism and habitat loss drove its listing as endangered in the past; conservation efforts have aided recovery.
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.
