Bicolored antbird

The bicolored antbird (Gymnopithys bicolor) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Colombia, Costa Rica, Ecuador, Honduras, Nicaragua, and Panama.

The bicolored antbird is 13.5 to 15 cm (5.3 to 5.9 in) long and weighs 28 to 37 g (0.99 to 1.3 oz). The sexes are the same. Adults of the nominate subspecies G. b. bicolor have a brownish chestnut crown and nape. They have bare blue-gray skin around the eye, a gray forehead, a broad gray band behind the eye, and black cheeks. Their back, rump, wings, and tail are brownish chestnut. Their throat and breast are white with a brown band from their cheek along their flanks.

Subspecies G. b. olivascens of the bicolored antbird is much like the nominate but is dull brown behind the eye rather than gray. G. b. daguae is like a darker olivascens. G. b. aequatorialis is darker still, with a rufous forehead and blacker sides. G. b. ruficeps has a brighter rufous forehead and crown than aequatorialis, is blacker behind the eye, and has a darker reddish back and redder sides.
