Carnivorous species that feeds on a wide range of vertebrates, including lizards, birds, and mammals (rodents, other bats). Adults feed within several hundred feet (meters) of their roost
and bring prey back to the day roost to share with roost-mates. In one roost studied in detail, bats fed mostly on birds ranging from 0.7-5.3 oz (20-150 g) in weight; major prey included one species of parakeet and the groove-billed ani, two species that sleep in groups at night.
Monestrous and monogamous; young bats remain in their natal roost long after they are weaned.
Not threatened, though uncommon throughout its range. Roost trees and foraging habitat threatened by forest destruction.
