Chestnut-bellied Cotinga

Breeding males are glossy black with purplish head and greenish sheen on body. Nonbreeding males have pale eyebrows and staring yellow eye. Females are plain dark brown and typically have dark eyes. Forages by walking on ground. Sometimes in mixed flocks with other blackbirds at feedlots. Also, walks along parking lots, golf courses, or roadsides. Females similar to Brown-headed Cowbird, but with longer, thinner bill and longer tail than cowbird.

Fairly common in the high Andes, where found at bogs, lakeshores, along streams, in agricultural areas of villages, usually near water. Feeds on the ground with a hopping and shuffling gait, sometimes cocking tail. Often in same areas as similar but larger and less numerous White-winged Cinclodes. Cream-winged is distinguished by duller brown (less rusty) upperparts, pale buffy tail corners (bold white on White-winged), and narrower white wing stripe shown in raised wing song display.

A large eagle with rich brown plumage, wide wings, and seven well-splayed “fingers” at the wingtip. Adults are entirely dark brown; juveniles and immatures at rest show a distinctive wide white band bordered with black on the wing. In flight, this transforms into a white traverse band on the underwing that forms the base of the primary and secondary feathers. Birds take about four years to attain adult plumage. Frequents open grasslands, deserts, scrub, wetlands, and mountains, and is a regular carcass feeder along with vultures.
