Black Vultures have been known to kill live animals..
Bell County trapper Gary Silvers witnessed a vulture kill a few years ago when he set up on a ranch along Hartrick's Bluff close to a roosting site. He saw half a dozen or so vultures swoop in on a heifer and peck out its eyes just as the calf was being delivered. Then another group of vultures went to work on the newborn calf.
