There is a higher incidence of rabies in other kinds of wild mammals like skunks, foxes and raccoons. In actuality there are only three species of vampire bats that live primarily in Mexico, Central and South America. It weighs less than a penny. Their echolocation is so acute that they can detect an object as fine as a human hair a couple of millimeters above the water's surface. A single little brown bat can eat at least 600 mosquitoes in an hour and a colony of Mexican free-tailed bats in central Texas can consume 250 tons of insects in one night.
Many bats feed almost exclusively on night flying moths, many of which are major agricultural pests.
The Chiricahua mountains in southeast Arizona probably has the largest diversity of bat species in the United States. There have been 24 species of bats found in the Chiricahuas from 3 families. Almost all the bats that are found in the Chiricahuas are insect feeders, two species are nectar and pollen feeders and have even learned to take advantage of hummingbird feeders in peoples yards. Most of the bats found in the Chiricahuas mate in the fall and the females give birth, usually to one pup per year, starting in early summer. The Desert Red Bat can give birth to twins or sometimes even four pups.
