Flying foxes have babies once a year, giving birth to only one at a time. At first the mother has to carry the baby on her breast wherever she goes. Later she leaves it hanging up, and brings back food for it to eat. Sometimes a baby bat falls down to the ground and squeaks (尖叫) for help. Then the older ones swoop (俯沖) down and try to pick it up. If they fail to do so, it will die. Often hundreds of dead baby bats can be found lying on the ground at the foot of a tree.
