About Grallaria ridgelyi Krabbe, Agro, Rice, Jacome, Navarrete & Sornoza, 1999
Grallaria antpittas, the group this species belongs to, are described as a wonderful group of plump, round antbirds whose feathers are often fluffed up; they have stout bills and very short tails. The jocotoco antpitta (Grallaria ridgelyi) is the largest member of its antpitta family. It measures 20 to 24 cm (7.9 to 9.4 in) long and weighs about 150 to 200 g (5.3 to 7.1 oz). Males and females have identical plumage. Adult jocotoco antpittas have a black crown and brownish olive nape, with a large, somewhat shaggy, fan-shaped white patch extending from the bill to below the eye. Their ear coverts are gray. Their upperparts are brownish olive with a black wash that becomes less prominent from the mantle to the rump. Their tail is reddish brown. Their flight feathers have blackish inner webs and cinnamon outer webs, and their upperwing coverts are brownish olive with a black band. Their throat is snowy white. Most of their underparts are light gray, which darkens on the flanks; the flanks also have a brownish olive wash. Their undertail coverts are brownish olive with fine black bars. Both sexes have a dark red to crimson reddish brown iris, a black bill, and blue-gray legs and feet. Juveniles are similar to adults but have more muted coloration and a chestnut crown. The jocotoco antpitta is known only from a very small number of locations in southeastern Ecuador and adjacent Peru. It was originally thought to be restricted to the upper Chinchipe River drainage in Zamora-Chinchipe, Ecuador, but a population was discovered in 2006 in Cordillera del Cóndor, Cajamarca, Peru. It lives on steep slopes in wet, dense, mossy forest that contains Chusquea bamboo stands and silvery-leaved Cecropia trees. In Ecuador, it occurs at elevations between 2,300 and 2,650 m (7,500 and 8,700 ft). Observations of the Peruvian population were made at about 2,250 m (7,400 ft).
