Any abnormal bumps on your parrot's body should be examined by an avian veterinarian.
A growth occurring on the body or wing of your bird could be a tumor or feather cyst and should be examined by an avian vet to determine which it is. An abnormal lump or bump on your bird could also be an abscess where the tissue becomes swollen or inflamed due to bacterial infections. Other bulges found on your bird could be large deposits of fat underneath the skin or an internal organ swelling because of disease. Sometimes, a healed fracture may leave a lumpy area. A ruptured air sac will result in air becoming trapped under the skin, which feels firm and hollow, like a small balloon.


Feather cysts can be hereditary or brought on by trauma and are usually the result of the feather failing to penetrate the skin, causing it to remain folded up underneath. Infections may result in an abscess forming, or a feather follicle may become inflamed or infected. Fatty tumors, called lipomas, are usually the result of a bird consuming too many calories, depositing fat under the skin.


Your bird needs to be physically examined by an avian vet to determine the cause of the lump.


A cyst can permanently be removed through a more extensive surgery, which completely removes the cyst and destroys the follicle. Without totally removing the follicle, the cyst may return. Other causes of lumps can be addressed by your avian vet and treated appropriately. Subcutaneous emphysema (air under the skin) can be drained by an avian vet, but it may recur. Lipomas can be surgically removed, however, they may come back, unless the diet and exercise level of the bird is addressed and corrected.
