The Red-and-yellow Barbet (Trachyphonus erythrocephalus) is a species of African barbet found in eastern Africa.

The males of the species have distinctive black (spotted white), red and yellow plumage, while youngsters and females are similar, but a little more dull.

The species lives in broken terrain and both nests and roosts in burrows.


Description

Red-and-yellow Barbet adult males have distinctive plumage made up black with spotted white, red and yellow. It has a black forhead and crown with a slight crest. The nape is orange and red with black spots. The side of the neck is red, going into yellow. The back is mostly black with white spots. The tail is a blackish brown with up to eight cream spots forming bars. The under side of the tail is yellow with black bars. The chin and throat are yellow, and there is a black patch at the centre of the throat. The throat is bordered by areas with more orange areas. The breast is orange to red-orange, becoming more yellow at the sides, with a dark band with white spots crossing through the middle. The lower breast and belly are yellow. The wings are black with brown wing feathers. All feathers on the wing have white spots, giving a spotted or banded appearance. The long bill is typically red. The skin around the eyes is a dark grey or black, while the eyes themselves can be a yellow brown, a dark brown, a red brown or a shade inbetween. The legs are a blue-grey, and the feet are the same colour.

The female is similar to the male, but is, overall, much duller, with less red and orange, and more yellow and white. Specifically, females lack the throat patch, and typically lack the crown. Young birds are also duller- they typically have less red and orange, as with the female. The spots on the back are less white, and all blacks are more brown. The eyes are typically grey.
