The olive-backed bearded bird ( Capito aurovirens ), also known as the black bearded bird , is a species of the American bearded bird (Capitonidae) family. It is not identical to the black bearded bird ( Gymnobucco bonapartei ) belonging to the African bearded birds . The olive-backed bearded bird is found in South America. It is a heavily built bird with a short, powerful beak.

The IUCN classifies the species as not endangered ( least concern ).

Appearance

The males reach a wing length of 8.1 to 9.1 centimeters, the tail length is 5.8 to 7.3 centimeters and the beak is between 1.9 and 2.4 centimeters long. Females have comparable body dimensions.

The males are red from the forehead to the neck, a narrow white stripe runs between the forehead and the base of the beak. The eye region is greenish black, the ear covers and the sides of the neck are dark olive green. The back is olive green up to the rump. The brownish olive-colored tail is slightly stepped, on the upper side of the tail the feather shafts are brownish, on the underside of the tail they are matt cream-colored. The chin is whitish, the throat and chest are golden yellow to orange yellow. The sides of the body and the flanks are olive green, the belly is lighter gray-yellow. The eyes are red-brown to orange-red. The legs are gray. Females differ from males in the lack of red head plumage. Their heads are cream-colored to the nape of the neck. The chest and throat are a little more yellow than the males.

Distribution area and way of life

The olive-backed bearded bird occurs in the lowlands east of the Andes. The distribution area extends from the south of Colombia over the east of Ecuador to about the middle of Peru and the north-west of Brazil to the Rio Negro and the Amazon to Tefé . The habitat is the lowlands, but in some valleys at the foot of the Andes it also occurs at altitudes of 500 to 600 meters. Basically he stays near water. Among other things, he colonized the Várzea , swampy forests in floodplain regions. It not only colonizes primary forest , but also high, densely grown secondary forests. The distribution area overlaps somewhat with that of the polka-dot -bearded bird ( Capito niger ), which, however, generally inhabits drier regions than the olive-backed bearded bird.

As is typical for bearded birds, fruits and berries make up a large part of the diet, but it also eats insects. As yet nothing is known about the reproductive biology of this species.
