In labs, a vampire bat will feed on anything - even a snake - but in the wild they prefer cows, whose blood they drink mostly at night while the livestock sleep. Instead, it feeds mostly on dozing cattle that have been introduced into the bats' range - mostly from northern Mexico down to Argentina and Chile - over the past few hundred years, Riskin said. Thing is, the common vampire bat rarely chases small animals anymore. The skill might have been useful for chasing down small, swift animals that wouldn't sit still for a feeding event, Riskin told LiveScience. Vampire bats must have regained the ability to run, says Cornell University researcher Daniel Riskin, who led the new experiments. 1.3K views, 17 likes, 1 loves, 3 comments, 6 shares: Are your kids wondering: 'Do bats. Most species of bats, if asked to run, can do little more than flop around like fish out of water. Scientists think they generally stopped running long ago, as evolution gave flight capabilities to their forelimbs. A new study found fleet-footed vampire bats can break into a loping run on all fours, at least when coaxed on a treadmill.īats are the only mammals that fly.
