usually roost in caves, in fact they are cave ceiling 'dome roosters' but they will also roost in a variety of other less suitable sites such as hollow trees, old wells, mine shafts, and even abandoned buildings.

Through echolocation, a method using ultrasound and echoes, bats are able to locate prey as well as communicate with other bats.  Bats are not blind, but their radar sensing is much more useful and better than their eyesight, especially since they are active at night!

Only the old world bats, such as the very large Flying Foxes, do not use this method of communication and hunting prey.  Instead, these bats rely on their eyesight, even though they are colorblind, to find their food which mostly consists of fruits and nectar.

Most bats, including those in North America, eat insects such as mosquitoes, moths, crickets, gnats, roaches, beetles, and ants. Some of these insectivores can consume between 600 to 1000 mosquitoes and insects in a single hour!

Several tropical bats consume nectar from flowers. These bats are helpful in pollinating different types of tropical plants and fruit trees. Finally, there are a few bats that are carnivorous, eating birds, mice, lizards, frogs and fish.

Most bat species generally pose little threat to humans. The greatest legitimate concern regarding human health and bats is their ability to transmit diseases. As mammals, they can transmit diseases such as rabies through their bite. For this reason, handling bats should be avoided or if necessary, done with heavy gloves.

Bats and birds are both vectors for zoonotic pathogens (carriers and spreaders of disease that can be spread to humans)
