During that time, a strong bonds exist between mother and young. Mothers recognize their own young even when they have to identify them within huge aggregations of hundreds or even thousands of other baby bats. The mother is guided by scent and vocal communication to its own young. After the young has grown up and learned to fly, it begins to forage on its own, and the mother weans it. Bat activity and diet.
Bats are active at night and rest during the day.
At dusk or shortly after nightfall, bats leave their roosts and head straight to their feeding areas to begin foraging. Many bats spend the whole night outside of their day roost and do not return until shortly before dawn. Usually bats have a number of other places, called night roosts, near their foraging area, for shelter and rest during the night. Neotropical fruit-eating bats and bats that take large insects or small vertebrates from the vegetation or the ground use their night roosts also as 'dining' roosts. Fruit-eating bats carry fruit from the fruiting tree to their temporary dining roost and process it there.
