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.
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.
