Flappies 

Flappies is what a young bat does prior to being able to fly. It hangs on to something stationary like a tree branch with its feet, while flapping its wings vigorously, mimicking flight, in order to exercise and strengthen the muscles that will soon be required when it starts to fly. Older adult bats in captivity past the age of flight also engage in this activity.

A baby bat practices flappies every day until it is ready to fly.
