The vulture does its best to keep itself clean. Observations have shown that each bird spends from two to three hours a day preening itself. Also, they will bathe in water whenever they can, submerse, shake, and scrub for half an hour. Then they walk up on the bank and hold their wings out to the sun to dry.
Vultures can fly up to 200 miles a day, but they are also homebodies. Some families of vultures have been known to use the same roost for 100 years or more. For years the vulture has been classified as a bird of prey along with hawks, owls, and eagles. But in 1994, due to DNA analysis and other studies on anatomy, physiology, and behavior, the vulture has been reclassified and placed in the stork family.
