Feather Destructive Behaviors (FDB)/ Feather Picking/ Feather Plucking

Feather destructive behavior, or feather picking/plucking, is when a bird picks out its feathers


The willful damage or destruction by a bird of its own feathers. The general term of “feather destructive behaviors” (or FDB) encompasses any form of a bird’s self-inflicted feather damage, including shredding the feathers, biting them off, pulling them out, etc.


Depending on the manner in which a bird damages its feathers, one might see anything from an overall rattiness of some feathers, to bald spots, to areas where abnormal numbers of down feathers are visible (meaning the overlying coverlet feathers have been removed). Contrary to what some sellers might say, a normal molt does not result in bald spots.


As avian behavioral consultant Sally Blanchard once commented, there are likely as many reasons birds might damage feathers as there are birds that damage feathers. A generalized symptom of stress, causes (etiologies) can range from medical issues (malnutrition, infections, systemic disease, allergies, etc.), to management issues (inadequate sleep, improper caging and cage location, etc.), to psychological problems (over-dependence, threatening children and/or other pets, stress in the owner’s life, etc.) Unlike some uneducated people’s opinions, a FDB bird does not automatically indicate the owner is a failure, that the bird is unhappy, or that the bird is sexually frustrated and needs a mate. FDB is usually much more complicated than that.


Since many of the possible causes of FDB are medical, the first step is to have a full medical work up done by an experienced avian veterinarian. After medical testing is accomplished without identifying a medical etiology, management practices need to be minutely analyzed. After management is studied and found to be adequate, then and only then can an owner assume that psychological stressors might form the basis for this behavior. Note: Please refer to the medical index on this site for further information regarding the medical causes of FDB.

I am getting a Pionus from a lady, and she told me the previous owner had her wings clipped at a pet store and they cut them jagged. So this caused her to itch, and began her feather plucking. She has yet to stop so I am wondering how to stop her feather plucking and re heal her belly.

hmmm....there doesn't seem to be any real answers for birds who feather pluck and have no underlying medical reasons for doing it. More research is needed on why this happens!!
