The Pemba flying fox is a large fruit bat weighing 400 – 650 g (0.9 – 1.4 lb.). Its diet consists of the fruit and flowers of a number of plants. Primary and secondary forest, graveyards and mangroves provide roosting sites. The Pemba flying fox is very social and has been found in large colonies until recently. The Pemba flying fox is found only on Pemba Island Tanzania. The island was originally forested, but only remnants of the primary forest remain. Estimates of the status of the Pemba flying fox have varied considerably recently. Studies in 1989 suggested a dramatic population decline, with fewer than 10 individuals being seen, and the species was considered to be on the brink of extinction. However, in 1992, surveys indicated a population in the region of 2400-3600, although it was estimated that the population may have declined significantly in the preceding decade.
