Simply put, the butt-ugly turkey vulture has a thing or two to learn about table manners. When approached by a predator, this foul fowl will regurgitate the entire contents of its stomach. The stench of its up-chuck is said to be unbearable, and wards off most potential predators on its own. However, some do actually choose to eat this humble offering from the turkey vulture, while meanwhile, the vulture is far more light and can fly away more easily. We imagine this works like gangbusters. After all, would you approach a guy or girl at a party that just threw up in the cheese dip?
