Desert Duets: Lesser Long-nosed Bat Babies Web Page
Lesser long-nosed bats that migrate to the U.S. return to the Southwest as early as the second week in April. The females and males live in separate roosts. Bat babies are called pups. The part of the roost where they are born is called the "nursery colony." Mother bats give birth to one pup each year. Lesser long-nosed bat pups are born as early as May and continue to be born throughout the summer.
Most pups are born furless. The mother bat uses her wings like arms
and wraps her baby inside them. Pups drink their mother's milk. Baby
bats can't fly. Babies usually stay in the roost until they
are developed enough to fly. Mother bats recognize their pups by their
smell and their voices.
