It clings to the mother bat and drinks milk from her. When the pup is about four months old, it learns to fly. Depending on the species, bats can be gray, brown, white or reddish brown. Bats are very sociable animals, and live in large colonies. Depending on the type of bat, their life span is between four and thirty years.
Bats like to live in dark places.
Caves, holes in trees and even buildings are favorite homes. Because bats sleep during the day and are active at night, they are called nocturnal. Bats sleep upside down. They use their feet to grasp onto a twig or board, and when it is cold, they hang close together. Seventy percent of all bats eat insects.
