Black-and-gold Cotinga

Overall the Cape Griffon is creamy-white, much paler and larger than the White-backed Vulture. At close range, the adult’s eyes are honey-colored, and there is a speckled stripe along the middle of the wing. They nest in small to large colonies in hills and mountains but will fly hundreds of kilometers to forage. The similar White-backed Vulture is smaller and darker with a wing that is more contrasting between flight feathers and the remainder of the underwing; at close range its dark eyes are visible.

Small, restless and colorful tanager of montane forests that often joins mixed-species flocks. Mostly greenish yellow, but note the blue forehead and eyering. The bill and area around it is black, with another back patch on the throat. Note the orange breast dark streaks on the back.

Fairly dull vireo, intermediate between Blue-headed and Plumbeous. Grayish-olive overall, but with yellowish flanks and greenish back. Note white spectacles contrasting with gray head and two whitish wingbars. Breeds in mixed coniferous forests, especially in mountainous areas; winters in Mexico. Often separable from Blue-headed and Plumbeous Vireos by range, but can overlap during migration and winter. Cassin's is less contrasty than Blue-headed, especially between the gray face and whitish throat, and the greenish back blends into the nape and crown. Some birds are best left unidentified.
