Chachapoyas 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 Chachapoyas antpitta is about 14.5 to 15 cm (5.7 to 5.9 in) long and weighs an average of about 42 g (1.5 oz). The sexes have the same plumage. Adults have a mostly dark reddish yellow-brown crown, upperparts, wings, and tail with lighter edges on the flight feathers. They have a pale buff eyering. Their throat and breast are reddish yellow-brown. Their belly is a paler reddish yellow-brown with a whitish center and their flanks are a reddish yellow-brown whose intensity is between those of the breast and belly. Both sexes have a dark brown iris, a slate gray bill, and blue-gray legs and feet.

The Chachapoyas antpitta is found on the eastern slope of the Peruvian Andes in the departments of Amazonas, San Martín and Huánuco. Its range is south and east of the Maranon River and north of the Huallaga River. The latter river separates it from the Panao antpitta. Its exact habitat requirements have not been documented. However, it appears to favor the floor and understory in the interior and edges of humid montane forest heavy with moss and epiphytes and with much Chusquea bamboo. In elevation it is known between 2,400 and 3,900 m (7,900 and 12,800 ft).

The Chachapoyas antpitta's diet has not been detailed but is known to include insects. Its diet is assumed to be similar to those of other Grallaria antpittas which include other arthropods and earthworms. It runs or hops on the forest floor and stops to find prey by flipping aside leaf litter and probing the soil.
