Bestimmung

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.<p>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.

Taxonomie

What is now the bicolored antbird was originally described as Myrmeciza leucaspis and included what is now the white-cheeked antbird (now Gymnopithys leucaspis). The current bicolored antbird was described as a separate taxon by the American amateur ornithologist George Newbold Lawrence in 1863 and given the binomial name Pithys bicolor. The two were split into separate species based on the results of a genetic study published in 2007 that found that the white-cheeked antbird was more similar to the rufous-throated antbird (G. rufigula) than it was to the bicolored antbird. These three antbirds are the only members of genus Gymnopithys.<p>The bicolored antbird has these five subspecies:

Verbreitung und Lebensraum

The subspecies of the bicolored antbird are found thus:<p>The bicolored antbird primarily inhabits lowland and foothill terra firme evergreen forest and nearby mature secondary forest. It almost entirely remains in the forest undergrowth. In elevation it reaches 1,750 m (5,700 ft) in parts of Central America though only 1,600 m (5,200 ft) in Costa Rica and 1,500 m (4,900 ft) in Panama. In Colombia it occurs below 1,000 m (3,300 ft) and in Ecuador below 750 m (2,500 ft).
