Parrot Feather Problems

Feather loss can have several different causes. It could simply be a perfectly natural molt, or it could be down to parasites. Psittacine Beak and Feather Disease are other possibilities; or the parrot may be plucking itself - or being plucked by its cage-mates. The various causes are outlined below.

Allergies

Parrots sometimes self-pluck and self-peck as due to skin irritation. This could be caused by a certain type of food, or perhaps chemicals in the environment (e.g. cleaners, household products, air-fresheners). Finding out what the irritant is can take time, and it is always worth consulting a vet for advice.

Baldness

This can be brought on by a number of different factors – self-plucking, plucking by another bird, hormonal imbalance, mineral deficiency, Psittacine Beak and Feather Disease (PBFD), feather mites or ringworm, or genetics. Cockatiels suffer from baldness more than other species, and genetics seems to play a large part in that fact.

Bleeding

When a parrot is growing new feathers during the moulting season, or when young birds are producing their adult plumage, feather bleeding can occur. A new ‘pin’ feather contains blood vessels, without which the full feather would not be able to grow. If these are damaged during the early days, they will bleed like any other wound.

A patch of blood on an adult bird’s coat is most likely to be one of these pin feathers. In extreme situations, the damage can result in the loss of so much blood that a small parrot like a budgie can weaken, and even die. The larger pin feathers – those associated with primary wing and tail feathers – bleed the most if damaged.

Once spotted, the bleeding must be addressed at once. The parrot must be caught, and the broken end of the feather must be held tightly for ten minutes. (Note: the pressure should be exerted on the feather itself, not the bird’s body – squeezing the budgie can cause suffocation.) Once the bleeding has stopped, arrange a trip to the vet to have the broken pin feather removed.

Pin feathers above the cere and nostrils can easily break, but the bleeding involved here is minimal and soon stops.

Color

Feather color can sometimes change as a result of damaged follicles, medication, or too much vitamin A supplement. The colour change is temporary, and will be remedied at the next molt.

Cysts

Cysts occur when a feather fails to break through the skin. It will continue to grow beneath the surface, producing a lump on the parrot’s skin. The primary wing feathers are the most commonly affected ones. The cause is uncertain, but malnutrition, genetics and infection of a follicle have all been implicated. Cysts won't disappear without surgical intervention. The most commonly affected parrots are macaws and budgies.

Fat Tumors (Xanthomas or Lipomas)

These are made from fat cells beneath the skin, usually occurring in overweight birds, and most commonly in sulphur crested cockatoos and budgies. Poor diet and obesity is the usual cause, although thyroid gland conditions and genetics can also play a part. Large tumors, although usually benign, are unsightly and begin to restrict movement as they grow. They can also become infected. Affected birds will peck at themselves, resulting in feather loss, bleeding and infection. An improved diet (fewer oily seeds) and additional exercise will go a long way to solving the problem. Iodine supplements in the drinking water are often prescribed by vets too. In severe cases, surgery may be needed.

Frayed Feathers

This is usually a sign of mineral deficiency. Other symptoms include itchy skin and feather loss. Making sure your birds all have access to a mineral block will usually cure the problem, or a vet may recommend adding supplements to the parrots’ water.

Plucking Feathers

If a parrot starts plucking its own feathers, there’s an underlying health problem. Unfortunately, it’s not obvious which of the many possible ailments is to blame. It could be parasites, an allergy, low air humidity, lack of fresh air, stress, boredom, mating hormones, liver disease, cancer, bacterial or fungal infection, malnutrition, heavy metal poisoning, or simply a bad habit.

A trip to the vet’s is necessary to see if the underlying problem can be diagnosed, and if it turns out to be an environmental problem rather than disease, there are a few things you can do to get to the bottom of the plucking mystery:

• Watch your birds closely, and see if you can spot a pattern or trigger. Does the plucking occur when the parrot is angry, bored or stressed? Is another bird or object involved in the incident that leads up to a bout of plucking? Does it happen after feeding? Is your pet fine when you’re around – i.e. is the plucking due to loneliness?


• Assess the light, air and humidity situation. Is the parrot is getting a 50/50 balance of light and dark through the 24 hour day? Can you do something about the centrally-heated, moisture-free environment to dampen things down a bit (dry atmosphere can cause itching which might lead to plucking)? Does moving the cage to a different location help?


• Swap the cage equipment round. Make a new perch to give the parrot something novel to perch and nibble on.


• Is the bird in need of a bath? A simple case of itchy, dry, grubby skin could be the issue. A wide-nozzled mist spray can provide the moisture the bird needs. The shower will induce the parrot’s natural preening instincts, rather than his plucking ones. Don’t overdo it, though, if the dousing is making the bird panic.


• Check the food you offer the bird against the list of good foods given in this guide. Try some new ones, to see if you can plug a difficult-to-pinpoint nutritional gap.
• Do you often stroke the parrot on the back or belly? This can sometimes stimulate mating hormones, which sometimes inspire feather-plucking.


• Sadly, diagnosis is not the same as cure. Some parrots keep on plucking when the original stimulation has been identified and removed. If all angles have been covered and the behaviour continues, you’ll have to fit a collar or resign yourself to a semi-bald bird with a bad habit.

Plucking Other Birds’ Feathers

This is a variation on the plucking problem. A bird who is plucked by his cage mates will become very stressed, and can even die as a result. Isolating the perpetrator is the best short-term solution; but you will also have to assess the problem and see if you can resolve it in the long term. The guilty bird may have been frustrated – these issues are often sex-related. Providing a nest-box or a choice of potential mates may divert the bird’s frustrations away from plucking. Making sure there is more than one feeding station might help, too.

Poor Feather Condition

This vague category is included to alert owners to the possibility of a parrot’s diet being deficient in the essential amino acid methionine. Other symptoms of this deficiency include a flaking beak. Methionine can be found in many parrot foods, including Brazil nuts, sesame seeds, pumpkin seeds, sunflower seeds, eggs, and spinach. Supplements are an option, too. The feathers and beak can take up to a year to recover their former glory.

(Note: poor feather condition is associated with many other parrot ailments too)

Psittacine Pruritic Polyfolliculitis (Polyfollicles)

This is where multiple feather shafts grow from a single follicle. It sometimes causes inflammation of the follicle and surrounding skin, and often causes itchiness or bleeding. In some birds the condition appears to cause no problems. It most commonly affects the tail and back of the neck. This condition is thought to be brought about by a virus, although it is not a contagious one. Often a single bird in an aviary will be affected, and stress seems to be the main cause of a flare-up of the problem.
