Black-cheeked Mountain Tanager

Plump chickenlike bird found in grasslands. Body and wings entirely barred brown with paler buffy throat. In spring, males gather at display site and perform dance to attract females: look for them hunched over with ear-like feathers protruding from atop head and darker reddish-orange skin exposed on the neck. Inconspicuous and difficult to find away from display sites. Very similar to Greater Prairie-Chicken but no range overlap. Averages slightly paler and smaller than Greater.

Large chickenlike bird with a long tail. Chocolate-brown overall with pinkish-red legs and silvery frosting on head and neck. Restricted to southern Ecuador and northwestern Peru, where it occurs in subtropical and temperate forest from around 2,000 to 3,000 m. Typically in pairs or small groups in the mid levels of forest. Replaces Andean Guan south of Cuenca and west of Jaén; also note subtle differences in patterning: Bearded has more extensive silver on brow and a streaked, not scaled, breast.

The smallest of the crested penguins. Note the thin yellow eyebrows that, once past the eyes, flare out toward the rear of the head. The species consists of two subspecies, the Eastern and Western Rockhopper Penguins. The Western Rockhopper Penguin breeds on offshore islands off southern Chile and Argentina and on the Falkland Islands, while the Eastern Rockhopper Penguin breeds on various subantarctic islands around New Zealand and the southern Indian Ocean. The Eastern has even eyebrows with pink skin at the base of the bill; the Western has black skin at the base of the bill, with an uneven eyebrow shape. Vagrants occasionally reach the Snares Islands. Distinguished from Snares Penguin by thinner eyebrow and smaller bill, and from Moseley’s Rockhopper Penguin by shorter, less flowing crest.
