Long-eared Bat

The big eared bat, also known as the long eared bat or rabbit-eared bat, is characterized by an ear that is longer than the head length. It lives alone and does not mix with other bats. Beginning to sleep in September, the hibernating big-eared bat does not eat or move, the ear is folded under the arm, only the tragus is exposed, and the body surface temperature is only 5.5 ° C.

      Big-eared bats nest in burrows, deep rock crevices, and abandoned mine shafts, at most in small groups, because there are so few habitat sites that can accommodate large groups. Colonies of more than 100 big-eared bats in a single location are rare.

      When flying, the big eared bat turns its ears backward and stops on one side of the air to hunt. The big-eared bat's diet includes other bats, small mammals, large insects, birds and frogs. When hunting, they attack their prey at great speed and use their powerful mouths to kill them. Once the prey is dead, the bat takes it to another location and eats it.

    Big-eared bats have few natural predators. Occasionally one can hear the excited call of a big-eared bat.

     When big-ejected bats breed, males and females live in separate groups during the breeding season, with females forming small groups and individual males usually remaining isolated until late summer. Females give birth in June, one litter per year, each litter of 1 to 2. After birth, the young feed on the milk of the female until they can eat meat.
