LIVE CAM: Sneak Peek At Vampire Bats Grooming And Nuzzling Each Other

If jack-o'-lanterns that look like they've been blasted by Indiana Jones' Ark of the Covenant have got you down, don't fret. We've got the cure for your post-Halloween-blues, and it's not that last uneaten package of Whoppers in an otherwise empty candy bowl. Feast your eyes on a vampire bat colony live feed, courtesy of the Organization for Bat Conservation:

There are about 40 vampire bats - rescues from a zoo - living in this colony, says Rob Mies, Organization for Bat Conservation's executive director, in a video statement. Vampire bats are expert blood drinkers, whose teeth are evolved to slice into the skin of cows, pigs and other warm-bodied animals. With saliva full of proteins that keeps blood flowing, rather than coagulating, a full-grown bat can drink up to an ounce of blood at a time.

Despite their sanguinary tastes, vampire bats are social mammals. They'll groom each other, get in squabbles, sniff to say "hello" and beg for food. (If you spot any of these activities on screen, you can let a University of Maryland researcher studying the bats know here.)

Vampire bats rarely bite humans, nor are they a major threat for rabies, says the International Union for the Conservation of Nature. In fact, bats are frequently a force for environmental good - not harmful or spooky.
