There is no skin or blood tests available at this time to determine what a bird could be allergic to. Birds can develop allergies from food, molds and grasses, just like humans. Susan Club, DVM, stated in the January 2005 issue of BIRD TALK, that, ?nflammatory skin disease in parrots is a reflection of underlying allergic or some other unknown systemic inflammatory disease. The predominant clinical sign is plucking or damaging the feathers. In severe cases, birds might mutilate the skin as well. In many of these birds the skin looks inflamed, but not in all cases.?It is believed that some non-dusty birds (New World psittacines) are allergic to birds with lots of powder down, such as cockatoos and cockatiels (collectively Old World psittacines). Keep these birds in a separate room. Purchase a good HEPA air purifier.
In the case of a food allergy, you may want to switch to a pellet diet that is hypoallergenic. (Work with your avian vet to determine a special diet for your bird.) Also, you can eliminate item after item from the diet to see if the symptoms stop.
Take your bird to an avian vet for a thorough checkup. This will include blood work and possibly feather follicle biopsies. The vet may recommend an anti-inflammatory diet or drug therapy.
