Experiments suggest that the middle and inner ear and high-frequency vocals are highly important in guiding bats in flight and in their aerial feeding activities. Most bats feed on insects, but some kinds feed regularly on fruits, nectar, or fish, and some, the vampire bats, are peculiarly adapted to feed on blood.
Bats are nearly worldwide in distribution.
The tropical regions are best suited for them, and there the greatest variety is found. Thirty-two species of bats occur in Texas. In addition to the 32 species of bats living in Texas today, four others are known from fossil skeletal remains. Intensive search may reveal the presence of both Macrotus and Desmodus in Texas.
