Populations also are found in western Angola, southwestern Saudi Arabia and northern Yemen. It is locally common, although sizeable gaps in its distribution occur due to its habitat requirements.

Elsevier Science (2001), ISBN 978-0856610790〕 Its back and wings are maroon, with the shoulders heavily speckled with white spots. The underparts are maroon with heavy white spotting, and the head is grey with yellow patches around the eye, and a yellow bill. The neck plumage, used in display, is streaked maroon and white, the underwing and undertail are dark grey, and the feet are yellow.
Females are very similar but somewhat duller. Juvenile birds have the maroon and grey replaced with dark brown, the bare parts are a dull greenish-yellow, and the wing feathers have pale fringes. In flight, this pigeon looks very dark. Its flight is quick, with the regular beats and an occasional sharp flick of the wings which are characteristic of pigeons in general. The call is a loud ''coo coo''.
