Animals prefer to forage on the blossom of Eucalypts, paperbarks and turpentines, and they may travel up to 50 km a night in search of food. Other native and introduced blossoms and fruits are also eaten including mangoes. They also eat the leaves of trees chewing them to a pulp, swallowing the juice and expelling the pulp. Fig fruits are also eaten in this manner. Photo: C. Smith.

The extended wing of a black flying foxReproduction

Mating occurs from March through to April with males defending a territory of about 1 meter of branch. A small amount of courtship, usually neck biting, occurs before copulation; females give birth from August through to November. The mother carries the pup for 1 month after which it is left in a crèche. At an age of 2-3 months the pup will follow its mother at night to forage and develop life skills. After another 3 months the pup will gain independence. Photo: J. Epstein.
