Bats


This 2005 photo supplied by the National Park Service shows the nightly exodus of bats from Carlsbad Caverns National Park in New Mexico. Through mid-October, thousands of bats swarm out of the cave mouth each evening at sunset to hunt for bugs for their nightly meal and the public is invited to watch.
