Pemba Green-Pigeon

The Pemba green pigeon is a species of bird in the family Columbidae. It is a small and stocky pigeon, with an average length of 25 cm. The head, neck, breast, and underparts are greenish-grey, while the upperparts from the lower mantle to the rump are olive-green, brighter on the rump and uppertail-coverts and with a greyish wash elsewhere. There is a dark greyish-purple patch on the shoulder formed by the lesser wing-coverts. It is endemic to Pemba Island, off the northeastern coast of mainland Tanzania. It is most common in primary forest, but also occurs in secondary forest, gardens, and clove plantations. Its population is estimated to number 2,000–3,200 mature individuals, although some estimates are as low as 500.
