Answer
Audrey,

Parrots who bite their feet often do this in response to an illness.  He needs to be taken to an avian vet (one who specializes in birds) for a fecal and blood test.  He may also be getting a secondary infection in his foot due to the bleeding and exposure to normal cage germs.

Good luck,

Cindy
