About These Birds
Black-billed Peppershrike
The Black-billed Peppershrike is a stocky, large-headed vireo relative of Andean foothills in Colombia and Ecuador, distinguished from similar peppershrikes by its entirely dark bill. It inhabits the canopy and edges of humid montane forests and adjacent tall secondary growth. It feeds on large insects and caterpillars, deliberating gleaning prey from foliage with its stout, hooked bill.
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.
