About These Birds
Ashy-headed Greenlet
The Ashy-headed Greenlet is a small vireonid found in várzea and gallery forests of the Amazon basin. Weighing about 11g with a wingspan near 10.8cm, it has a grey head and yellow-tinged underparts. It forages actively in the forest canopy and sub-canopy, gleaning small insects from foliage.
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.
