The turkey vulture can be found from southern Canada to southern South America. Its body length is about 27 to 32 inches, and the wingspan is about 7 to 10 ½ feet.  The turkey vulture usually weighs about 20 pounds.   If a vulture can't find carrion within three days it will become desperate and start looking for food to kill.  Black vultures are found from southern U.S. and to southern South America.
