Litters Per Year:
Females nurse in colonies made up of 100-200 bats.
Males and females roost separately.
Male groups consist of 100-200 bats.
However, few dominant males will roost with female colony’s while each guarding 20-30 smaller female groups.
They do not cluster in tight groups like other bats and they use the same roosting spot year-round.
Sonoran desert scrub areas with caves, mines, and rock shelters.
They do not hibernate.
They do not migrate.
They capture prey in flight and on the ground.
They are the only bats known to catch caterpillars.
They are among the very few insectivore bats that supplement their diets with cactus fruit.
When roosting, they’re able to walk bipedally (on two feet), a manner rare among bats.
They do this while hanging from the ceiling.
The bat swings each foot back while bending its head toward the rear, so that it is looking straight ahead while walking backward.
This makes it appear as if it’s walking forward!
