"The bats seem to have adopted a simple trick: once another individual is close enough for your biosonar to pick up its echo, copy this individual's flight direction within four to five of your own wingbeats," Holderied explained in a news release. Many birds fly in distinctive V-formations.
Beside this, what do bats look like when flying?
While bats come in many sizes and types, these bats are small, with a body size roughly that of a common mouse. Their wings are fascinating, being the rough equivalent of our arms and hands with greatly elongated fingers, and a very thin skin/membrane webbing stretched between the long skinny finger bones.
Correspondingly, do bats fly together?
"These bats roost in groups and then they fly out from their roost very close together, so a lot of people have wondered how they manage to fly out in groups without being confused," Moss said.
Compared to a similar-sized animal like a rat that lives only two or three years, bats live between 20 and 40 years. Researchers theorize this has to do with the ability of bats to fly.
