Vampire bats may be bloodsucking creatures of the night -- but they also form strong friendships and help each other out in times of need, a study has found.
The study, published in the journal Current Biology on Thursday, found that vampire bats who formed social bonds in captivity maintained those bonds even after they were released back into the wild.This is significant because it's often difficult to tell whether"partner fidelity" in animal relationships is due to the immediate costs and benefits of helping each other, or due to some shared relationship history.
Then, the bats were released back into their original roost, wearing small sensors to monitor their behavior. Even though they were now part of a bigger group with other bats who hadn't been part of the experiment, the"test" bats who had lived together in the lab stuck together -- they had higher levels of social grooming, food sharing, and close contact with each other.
