Rats are snatching bats out of the air and eating them
Brown rats (Rattus norvegicus) figured out how to get inside the kiosk and climb up to the bats’ landing platform at the entrance, using a curtain the researchers placed inside the kiosk for filming purposes. From August to October 2020, cameras captured the rodents — standing on their hind legs and using their tail to balance — grabbing bats mid-flight, killing them with a bite and dragging the carcasses away. The rats also caught bats as they landed on the platform.
Rats, especially brown rats, can be vicious little predators. It will be interesting to see if A) rats evolve further in predatory directions and B) bats learn to avoid them. Hats off to Dougal Dixon, you called it dude.
Note from birdhouse architecture: don't create a platform or perch near an entry hole that predators can stand on. Fliers can typically enter without it. Probably the rats can't climb upside down, but you might want to check that.
