Gathering in mixed-sex groups of up to 850 individuals to roost, the Pemba flying fox creates quite a spectacle. The bats remain faithful to the roost (often a group of large, mature trees), returning from feeding trips in huge flocks (4). The Pemba flying fox feeds on mangos, breadfruit, figs, flowers and leaves, and may be the only species on the island that disperses larger seeds, thereby proving essential to the survival of the plants that produce them (6). Unlike insectivorous bats (Microchiroptera), this species does not use echolocation, instead using vision to locate fruit (7).
The Pemba flying fox is thought to mate between January and April, with births occurring between June and August (4). The young become independent within three to six months (7).
