The leaf-nosed bats, family Phyllostomidae, are ecologically the most varied and diverse group within the whole order Chiroptera. Phyllostomid bats include within their number true predatory species. They take vertebrate prey including small Dove -sized birds. One example is the False Vampire, the largest bat in the Americas. Members of this family have evolved to utilize food groups. These groups include things such as fruit, nectar, pollen, insects, frogs, other bats and small vertebrates, and even blood.
The family gets its name from the often large, lance shaped nose projection. The nose is used to direct their sonar, though some of the nectar/pollen feeders have greatly reduced it. Because these bats detect sonar nasally, this “nose-leaf” is thought to serve some role in modifying and directing the sonar call.
