Part 2
"WHY???"
As with plucking, the causes of self-mutilation can be multiple, and each one can be interwoven with still others, making definitive causes impossible to detect. For instance, a broad-spectrum diagnosis of "pruritis" (itchy skin) is quite common in some cases of feather plucking and mutilation, yet further investigation is required in an attempt to identify the cause of "itchy skin". At the very root, most causes will fall into two general categories: medical and non-medical (psychological).
Medical Causes Could Include:
Endocrine diseases such as low thyroid levels, progesterone or testosterone imbalances, diabetes
Bacterial-related feather disorders such as bacterial sinusitis, feather folliculitis, Chlamydia
Virus-related/feather disorders such as PBFD, PDD, French molt, Psittacine pox, canary pox
Skin and/or feather infections
Fungal diseases
Internal organ diseases (Quakers are prone to Fatty Liver Disease)
Internal parasites such as roundworms and tapeworm
Internal tumors or kidney disease may cause birds to pluck diseased area
Intestinal, respiratory, or crop infection could result in a hyper-sensitive reaction, which in turn leads to pruritis
Nutritional deficiencies or food allergies
Hormonal imbalances
Guardia
Simple dry, flaky, itchy skin (or the itchy skin could be a secondary result of a medical cause listed above)
Ingested allergens, such as:
---certain proteins
---carbohydrates
---chemical additives (preservatives, colors, or flavors)
Inhaled allergens, such as:
---smoke
---cockatoo dander
---perfumes
---house deodorants
---pollen
---dust mold
Contact allergens, such as:
---laundry detergents
---deodorants
---perfume
---hair products
---litter or nest box material
---newspaper ink
*Note: As of this writing (December 25, 1997), it has been reported that the newest Avian Journal mentioned discovery of an unknown organism present in QMS afflicted birds. More research is under way to isolate the organism.

Potential Treatments
Obviously, the sheer number of possible medical causes is overwhelming, and makes pinpointing or ruling out any particular one (let alone a number of them) a painstaking and frustrating process. Hopefully you already have a veterinarian who is avian-certified and has an extensive background working with avian species. Tests can be conducted that can identify most of the medical conditions listed above, and other possible causes (such as allergens) can be identified through the process of elimination.
Your veterinarian should conduct a complete physical exam, looking for lumps, injuries, feather cysts, lipomas or other tumors. Diagnostic tests should, at a minimum, include a CBC (Complete Blood Count) and blood chemistry panels. Tests should be run for parasitic, yeast, fungal, and bacterial infections, as well as for psittacosis, Psittacine Beak and Feather Disease, and Guardia. Other tests may include radiographs or a skin biopsy. For a more in-depth look at tests that should be included in an exam along with explanations of their meaning and importance, please read "The Annual Well Bird Exam", by Lisa Paul, D.V.M.
Meeting nutritional requirements is vitally important in any avian species, since deficiencies can sometimes lead to plucking. Quaker owners face an especially daunting task here. While quakers are classified as "parakeets", there are traits specific to them; individualized and separate from those birds that are normally thought of as "parakeets". One veterinarian stated that the nutritional requirements of a quaker most closely matched those of a cockatiel, while another stated that food designed for "small parrots" (i.e, Conures, Senegals, etc.) would be more beneficial.
At any rate, providing good nutrition is imperative, and often a particular food can provide entertainment value as well. Raw carrots, green beans, spinach leaves, peas in the pod, corn on the cob, apples, bread sticks, wheat toast, zucchini sticks, mini bagels, and mini rice cakes are easily shredded and may provide an alternative to plucking. (Similarly, toys manufactured with 100% cotton rope or sisal rope may alleviate or reduce incidents of plucking).
Angela Lennox, DVM, is a very knowledgeable avian veterinarian who has taken an interest in QMS, and has treated several quakers suffering from this syndrome. Mrs. Lennox stated that although there will never be one definitive cause for QMS, she has found that most cases are related to some type of medical cause as opposed to psychological. Many of the quakers she has treated for QMS have been found to have some type of nutritional deficiency, most notably Fatty Liver Disease resulting from all-seed diets. Another frequent medical cause appears to be mega bacteria and yeast infections. While Mrs. Lennox agrees that plucking and mutilation in other species, such as the African Grey and Cockatoo families, can often be a result of psychological causes, she believes that this is rare in cases of QMS.
Several treatments exist for allergic skin and feather diseases. The first is to identify the source of the allergy and remove it. The second is to medically manage the problem by treating the signs of the allergies with antihistamines or steroids. Once the allergens are identified, desensitization programs attempt to reduce the bird's reaction to the offending antigens. The vet may administer a series of subcutaneous injections over a four-to-eight week period.
Hormonal imbalances are another oft-cited cause for feather plucking/mutilation. Unfortunately the most often heard response to this is, "Put the bird in a breeding situation". Needless to say, this is not always an effective, nor feasible solution.
Some veterinarians will prescribe different drugs in an attempt to treat plucking/mutilation syndromes. Progesterone injections, testosterone, Human Chorionic Gonadotropin (HCG), Haloperidol (haldol), and Prozac are some of the common suggestions. However, as with any treatment, there simply isn't a specific one that is going to be effective in all cases. Many times the drugs are only effective for a short time, if at all; and many owners have no desire to put their birds on antipsychotic drugs.
It is imperative that birds have the opportunity to bathe frequently, particularly in the colder, dryer seasons. Artificial heating tends to dry the air significantly, and in turn dries out skin rather quickly. Also investing in an inexpensive filter for your main water faucet may be useful in filtering out undesirable additives such as chlorine.
Making diagnosis even more difficult is the fact that many of these causes can also be effects of feather plucking or mutilation, creating a vicious cycle that could prove almost impossible to break. For instance, some types of skin (bacterial) infections may be a result of the mutilation to the skin, as opposed to the cause. Additionally, the plucking/mutilation can quickly and easily become a habit, and may continue even after the original root cause is found and treated effectively. In this case, the plucking/mutilation has simply "cycled" into a true behavioral problem..... resulting in a whole new set of questions.
Part II of this series will be posted in the February issue of "Winged Wisdom" and will concentrate on possible non-medical (psychological) causes, along with current and potential treatments.

Quaker Parakeets are “big bird personalities in small packages”, they are by all means awesome little birds, but watch out, they can be very aggressive little birds, but then…what bird isn’t…
