Much forest in the area has long been cleared primarily for coffee plantations, potatoes, beans and cattle-grazing, leaving scattered fragments of mature secondary forest and natural vegetation...The species nevertheless shows some tolerance of habitat degradation and disturbance and may recolonise areas from where it had previously disappeared." It does occur in at least three protected areas in
Colombia.

Their underparts are mostly gray to sooty gray with a whitish central belly and whitish edges on the breast, side, and flank feathers. Both sexes have a dark brown iris, a black bill, and gray to brownish gray legs and feet.

antpittas are a "wonderful group of plump and round antbirds whose feathers are often fluffed up...they have stout bills very short tails". The bicolored antpitta is 15 to 18 cm (5.9 to 7.1 in) long; one individual weighed 44.8 g (1.6 oz). The sexes have the same plumage. Adults

Threatened, then in 1994 as Endangered, in 2000 as Vulnerable, and in 2022 as being of Least Concern. Its estimated population of between 20,000 and 50,000 mature individuals is believed to be decreasing. "The species is threatened by

The bicolored antpitta is one of several antpittas that regularly come to feeding stations set up to view them. There they are fed earthworms, which are thought to also be a large part of their natural diet. In the wild they also feed on
