Diet and foraging

Most megabats are primarily frugivorous. Throughout the family, a diverse array of fruit is consumed from nearly 188 plant genera. Some species are also nectarivorous, meaning that they also drink nectar from flowers. In Australia, Eucalyptus flowers are an especially important food source. Other food resources include leaves, shoots, buds, pollen, seed pods, sap, cones, bark, and twigs. They are prodigious eaters and can consume up to 2.5 times their own body weight in fruit per night.

Megabats fly to roosting and foraging resources. They typically fly straight and relatively fast for bats; some species are slower with greater maneuverability. Species can commute 20–50 km (12–31 mi) in a night. Migratory species of the genera Eidolon, Pteropus, Epomophorus, Rousettus, Myonycteris, and Nanonycteris can migrate distances up to 750 km (470 mi). Most megabats have below-average aspect ratios, which is measurement relating wingspan and wing area. Wing loading, which measures weight relative to wing area, is average or higher than average in megabats.
