Pemba
Flying Fox is fox-like; face is uniform brown, without dark facemask; muzzle is long and tapering; eyes are moderately large, with chestnut-brown irises; and ears are pointed, naked, and blackish brown. Crown is dark brown to rusty brown, and some gray hairs can be present; nape has longer, coarser, and rusty red or rusty orange hairs, forming reddish mantle, extended as a collar; back is black, blackish brown, or dark reddish brown; hairs are rusty red or blackish brown, with some of them pale gray or rusty brown; pelage is dense and
15 mm
long mid-dorsally. Chestis dark golden brown, abdomen and flanks are lighter golden brown, and chin and throat and dark brown. Exceptionally, ventral pelage is darker or rusty brown at center and lighter on flanks. Wings are very dark brown and attach to second toe, and tibia and forearm are naked. Index claw is present. Skull is long and robust; rostrum is of medium length. There are 13 palatal ridges; ridges 1-5 are undivided; ridges 6-10 are divided; and ridges are 11-13 post-dental. Dentition is typical pteropine.
Habitat.
Primary and secondary (moist) forests, undisturbed traditional graveyards and mangroves, and small offshore islands from sea level only up to elevations of c.
45m
.
Food and Feeding.
The
Pemba
Flying Fox is strongly frugivorous; mangoes (
Mangifera indica
,
Anacardiaceae
) form the major part ofits diet. Fruit, flowers, and leaves from at least 16 genera in twelve families are eaten. It seems to prefer cultivated fruits.
Breeding.
Births of
Pemba
Flying Foxes occur in June-August, with young recorded in August—October; assuming gestation of 4-6 months, mating takes place in January—April.
Activity patterns.
The
Pemba
Flying Fox forages at night. Roosts can be found in tall trees such as M.
indica
, with a preference for
Erythrophleum
suaveolens (
Fabaceae
).
Movements, Home range and Social organization.
Pemba
Flying Foxes roost alone or in mixed-sex colonies of up to 5000 individuals.
Status and Conservation.
CITES Appendix II. Classified as Vulnerable on The [UCN Red List. The Pemba Flying Fox was downgraded from Critically Endangered (1996) because population grew from ¢.3000 individuals in 1992 to a current estimate of more than 22,000 individuals in 44 known roosts. Current classification is due to its restricted distribution (Pemba Island), continued hunting, disturbance of roostsites, and conflicts with local fruit growers. It is most common on western side of Pemba and occurs in protected areas (e.g. Ngezi Forest Reserve and Msitu Kuu Forest). A captive breeding program was established at the Phoenix Zoo (
USA
).
