Pale-billed Antpitta

Grallaria antpittas are a "wonderful group of plump and round antbirds whose feathers are often fluffed up...they have stout bills [and] very short tails". The pale-billed antpitta is 20 to 21 cm (7.9 to 8.3 in) long and weighs 96 to 124 g (3.4 to 4.4 oz). The sexes have the same plumage. Adults have a black forecrown, lores, and cheeks. Their ear coverts have black bases and blackish brown ends. Their crown is blackish brown that becomes dark olivaceous brown on their nape. Their back and rump are dark olivaceous brown with thin black tips on the feathers. Their tail is dusky brown. Their flight feathers are dusky brown with dark chestnut outer webs, and their upperwing coverts are dark chestnut. Their chin is black and their throat blackish gray. Their underparts are mostly light gray that is darker on the sides of the breast and becomes almost white on the center of the belly; the breast and upper belly feathers have narrow black tips. Their flanks and undertail coverts are buffy olive. Both sexes have a pale reddish brown iris, an ivory bill, and blue-gray legs and feet. Juveniles have a blackish gray head with black lores. Their nape's feathers have a brown tinge and cinnamon tips. Much of the rest of their plumage is cinnamon brown with black bars except on the lower belly, which is buffy with a creamy white center. …

The pale-billed antpitta is found on the east slope of the Peruvian Andes. Its range extends from central Amazonas Department south at least to southeastern La Libertad Department. It inhabits the understory of humid montane forest with a broken canopy, lush growth of epiphytes, and thickets of Chusquea bamboo. In elevation it ranges between 2,350 and 2,900 m (7,700 and 9,500 ft).

The pale-billed antpitta's diet has not been detailed but is known to include arthropods and is suspected to also include small vertebrates like frogs. It forages on the ground or within about 1 m (3 ft) of it, and usually in dense vegetation.
