Distinguishing Characteristics

Barbets are stout birds with heavy bills, and usually have brightly colored plumage. The upperparts of Black-girdled Barbet are black, with a large white or yellow white spots on each side of the back and on the tertials and inner secondaries, and white or yellow white uppertail coverts. The throat is brown; the breast is white, bordered below by a black band that crosses the belly (the black girdle); the lower belly is whitish, with red undertail coverts. The sexes are similar, but the male has a bright red crown and nape; the top of the head is black in the female.

Detailed Description

The following detailed description is based on Cherrie (1916) and on Short and Horne (2001):

Adult male: Very narrow black line above the bill, connecting to the lores and to a narrow black line just above the eye. Otherwise, forecrown, crown and nape bright scarlet red. Sides of the head black. Back black, except for white or yellowish white scapulars. Uppertail coverts pale olive green. Wings black, the outer webs of the tertials and inner secondaries yellowish white. Rectrices black. Chin and throat tawny olive, cinnamon, or brown. Upper breast white or buffy white, becoming pale greenish yellow on the belly. Flanks black, the black extending medially as a band across the lower breast, this band not quite meeting in the center. Tibial feathers dull green. Undertail coverts scarlet red, the longest feathers tipped with dull green.

Adult female: Similar to adult male, but the crown and nape are black.

Immature: Throat whiter, less dark brown; black of plumage is duller and browner; the red of the undertail coverts is paler, and barred with yellow; and the rectrices are more pointed. In its first plumage, the male may have a black crown.
