Final answer:
Female bats can recognize the call of their own pup, making the statement true.
Step-by-step explanation:
The statement is true.
Female bats in Bracken Cave can recognize the call of their own pup. This is crucial for the survival of the pups and for the mothers to be reunited with their offspring. Since the bats' calls are their only means of finding one another, the mothers have the ability to distinguish the call of their own pup from the calls of other adult bats. This helps ensure that each mother bat can swiftly reunite with her own pup upon returning to the cave.
