Bats exit their caves in whatever direction is open to them, using echolocation both to avoid collision and to locate food. It is a popular myth that they always turn left, a legend that may have first surfaced via an email campaign in the 1990s.Continue Reading
Bats are social creatures that generally roost in groups. Resting during the day, they arouse at night, circling within a cave before emerging in search of food. They often exit by following each other and so may appear to turn in a specific direction. They may return to their habitats to rest and re-emerge several times during a night feeding. The level of light from the moon and the length of daylight hours impacts their behavior since they return to shelter at sunrise.
All bats, however, do not live in caves. Bats may also live under the eaves of buildings, in rock crevices, beneath bridges and in trees. Of the order Chiroptera, which means "hand-wing," bats are the only known mammal truly capable of flight. Although they are able to see to some extent, they navigate primarily by emitting sounds that bounce off objects.
Echolocation enables bats to locate food and maneuver airborne with great accuracy and efficiency. According to Boston University's Center for Ecology and Conservation Ecology, experimental echolocation studies at Brown University and California Institute of Technology have developed a model sonar receiver based on a bat.Learn more about Bats
Bats communicate with each other through echolocation, the use of very high-frequency sounds. Using sound enables bats to visualize objects of any size in their environment.Full Answer >
Bats often roost in caves, but they can make use of almost any shelter. Some species make tents out of leaves, and others live in burrows made by other animals or in termite nests. Bats have even been seen roosting in flowers or in the webs of large tropical spiders.Full Answer >
Bats use echolocation by emitting sound waves; when those sound waves hit a nearby object, it produces an echo that is then bounced back to the bat. The bat then deciphers the echo as the existence of an object in the direction from which the echo came.Full Answer >
Bats migrate when the food supply becomes depleted in their current environment. Bats often migrate to the same places; however, not all bats migrate. Some species of bats choose to hibernate when the food supply runs low.Full Answer >
