Always a little creepy when the turkey vultures hover too close. Still, in the years I've lived down here in Florida I have grown to have a great appreciation for these creatures. (Okay, this is about to get graphic. You've been warned.)
Yes, it is gross that they eat things that have previously died -- and seem to prefer when those creatures have had time to ripen before digging it. I've seen them stand around a dead critter for hours waiting for just the right...I'm not sure what. However, they do a really fine job of cleaning up things like road kill. I've seen a medium dear disappear within 24 hours of the beginning of the feasting.
