Red-and-white 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 red-and-white antpitta is 17 to 18 cm (6.7 to 7.1 in) long and weighs 73 to 80 g (2.6 to 2.8 oz). The sexes have the same plumage. Adults have a bright rich rufous crown and nape. Many have a ring of bare grayish or bluish gray skin around their eye. Their back, rump, wings, and tail are a slightly duller and browner rufous than their crown and nape. Their throat and the center of their belly are white; the latter is yellow in the Cordillera de Vilcabamba. The sides of their breast are rufous-brown, and this color with some white mottling forms a band across the breast. Their flanks are rufous-brown with an olive wash. Juveniles are similar to adults but have a buffier hindcrown and nape with fine blackish bars. Their wing coverts and breast band are paler than the adult's. Adults have a medium brown iris, a black bill, and slate-gray to blue-gray legs and feet. Juveniles have a black maxilla with a yellow tip and a yellowish mandible; their iris and leg colors have not been described.

The red-and-white antpitta is found on the east side of the Peruvian Andes, mostly in Cuzco Department and slightly into Junín and Ayacucho departments. It inhabits the understory in the interior and edges of humid subtropical montane forest and mature secondary forest. It appears to favor areas where thick vegetation is regrowing such as in landslide scars, and is also associated with Chusquea bamboo stands. In elevation it mostly ranges between 2,100 and 3,000 m (6,900 and 9,800 ft) though there are records as low as 1,758 m (5,800 ft) and as high as 3,400 m (11,200 ft).

The red-and-white antpitta's diet has not been detailed but it is known to feed on insects and spiders. It is almost entirely terrestrial, where it runs and hops along the ground and up to about 1.5 m (5 ft) above it, usually in dense vegetation. It typically lunges to capture prey from leaf litter and other substrates.
