Black-bellied Bustard

The black-bellied bustard is 58–65 cm (23–26 in) long. The bill and legs are dull yellow. The male's upperparts have black and brown marks on a tawny buff background; the underparts are black. The head is boldly patterned with black, white and buff. The neck, long and thin for a bustard, is buffy brown with a thin black line down the front that joins the black breast. The tail is brown and buff with four or five narrow dark brown bands. The upper surface of the wings is white with a brown triangle at the base; the flight feathers have black tips except for the outer secondary feathers. The white of the wings is visible when the bird stands, contrasting with the black underparts. The female is plain buff, cryptically marked with darker brown mottling on the back and vermiculation (narrow wavy bands) on the neck and breast. The juvenile is duller and darker, with a dark grey crown and buff spots on the wing. The neck and rump patterns of both sexes, the male's white chin and lores, and the female's vermiculations are points that distinguish this species from its close relative, Hartlaub's bustard.
