The medical definition of this term entails an animal doing physical damage to its body, specifically involving skin and muscle. Most avian veterinarians do not use the term “mutilation” to connote various forms of feather destruction.
Many parrot behavior consultants and avian veterinarians agree that self-mutilation in pet parrots is likely physical in origin, not behavioral or “psychological.”
Seek the assistance of an experienced avian veterinarian who is willing to search exhaustively for the origin of this problem, such as cardiomyopathy (pathologies of the heart muscle), viral infections, etc.
