There is little specific information available on the biology of the white-collared fruit bat. However like other fruit bats from the family Pteropodidae, it is likely to mainly feed on fruit and nectar. Fruit bats are nocturnal, so emerge from their roost in the evening and are active at night. Unlike most other species of bats, fruit bats have limited use of echolocation, and rely on sight and smell to find food (3) (5) and (6).
Fruit bats have strong jaws which are used to tear through the tough skins of fruit while hovering beside them. Food may also be carried to a branch where the bat will hang upside-down by one foot, using the other to hold the fruit while it eats. Fruit bats do not ingest food whole, but instead chew it to a pulp, squeezing the juice out with a ridged palate in the mouth. The remaining pellet of dry matter is discarded (6).
A female fruit bat will only give birth once a year and the young take up to two years to reach sexual maturity, resulting in a low reproductive rate compared to other mammals of a similar size (6).
