How adorable! A bat maternity colony!Female bats, ready to give birth, will form maternity colonies. Often found in trees and tree cavities, they have also been found in buildings, or in this case, bridges. There have been signs of maternity colony preferences in different bat species, but as you can see here, these guys are pretty set with their man-made set up.
Thanks to Ellen Whittle for the footage.
