Pet birds can have many feather and skin disorders. In this article, we cover the most common ones along with their prevention, symptoms, diagnosis, supportive nutrition, and treatment options.
Specific Conditions / Resources:
- Beak and Feather Disease (PBFD)
- Beak – Flaky / Dry
- Brown Hypertrophy (cornified and keratinized cere)
- Nutritional Deficiencies:
- Argonine deficiency: results in curled wing feathers
- Riboflavin deficiency: clubbed down feathers
- Pantothenic Acid: niacin and selenium deficiency: general poor feathering
- Nutritional Deficiencies:
- Preen Gland Tumors – The preen / oil gland is enlarged and distorted in shape. As a result the small feathers over the gland become raised and the tail feathers tend to fall out and not regrow.
- Ringworm (patchy loss of feathers)
- Ulcerative Dermatitis (red, oozing, ulcerated skin)
- Xanthomas (orange thickened, dimpled patches of skin)
A hormonal imbalance and genetics are believed to be responsible. Baldness can also be caused by over-preening by a mate. Inactive, undersized and/or diseased follicles are common causes of baldness.
Patchy feather-loss on a bird can be a sign of Vitamin A deficiency, which can be treated by supplementing your bird’s diet accordingly. Patchy feather loss can also be caused by ringworms.
An abnormal molt occurs on some birds, causing them to lose all of their head feathers at once. The birds may be juveniles undergoing their first prebasic molt. It’s also possible that feather mites or feather lice may cause baldness.
Unexpected / Unusual Changes in Feather Coloration:
For example, in cockatiels the white feathers may take on a more yellowish color (doesn’t happen in white-faced cockatiels though).
Scattered feathers of an unexpected color can be an indication of damaged feather follicles (usually because of feather plucking).
Over-supplementation with Vitamin “A” may also cause these feather changes. Medication – for example administration of antibiotics at the time a bird is molting has caused temporary changes in feather coloration; these feathers are usually replaced with normal coloration feathers at the next molt.
It is easy enough to differentiate that – depending on whether a parrot developed these red feathers over time (which would be an indication of health problems), or whether they were born with it, which would point towards genetics / mutation.
Commonly seen in budgies and may be likened to catarrh of a mucous surface and occurs in many types of chronic ill health. Apparently, it is not caused by local infection, and ideally, treatment consists of finding and treating the underlying cause.
The cere (the structure containing the nostrils) hypertrophies, becoming cornified and keratinized. It may develop a prominent “hornlike” appearance.
This condition is most common in female birds and is believed to be associated with breeding in females and estrogen secreting gonadal tumors in males.
Treatment: Conventional vets recommend moistening and gently removing the heaped-up material (especially if it flakes and blocks the nares), and applying a little oily lotion, cod liver oil, Dettol or bland ointment.
Polyfollicles is the growth of multiple feather shafts from one follicle. It may cause no problems or may be associated with chronic inflamation in feathers and skin.
An itchy pollifelliculitis has been seen in lovebirds and budgies. The tail and dorsal neck area are the most common areas affected. This condition is thought to be caused by a virus.
Poor Feather Condition / Long Molts
Chlamydophila psittaci – Primary symptoms in birds would be an upper respiratory infection with nasal and/ or ocular (eye) discharge, poor feather condition, diarrhea with the possibility of conjunctivitis and other symptoms.
This is a disease that is transferable to humans. So if flu-like symptoms in the family exist and don’t seem to resolve themselves, the vet should urgently be consulted.
Deficiencies of minerals, such as calcium, zinc, selenium, manganese and magnesium, may be associated with brittle, frayed feathers and itchy skin. There may be alterations in color or discoloration of feathers. The plumage can appear dull. Feather loss and moulting disorders can occur.
Dietary: Poor feather condition / long molts and flaky beaks may be the result of a diet deficient in the essential amino acid “methionine.” The requirement for methionine tends to increase when accumulated levels of toxic substances in the body increase.
High levels of methionine can be found in sesame seeds, pumpkin seeds, sunflower seeds, Brazil nuts, fish, meats, eggs, as well as various lentils. Significant amounts can also be found in spinach, potatoes and boiled corn.
Supplementation is another option for birds that don’t have access or refuse to eat foods rich in methionine – such as spirulina, which is rich in this amino acid.
Once nutritional needs are met, it may take 9 to 12 months for new, better feathering and the flaky beak to be replaced with a new, smooth one.
A single bird was seen with a patch of feather loss on one side of its body associated with a thick, grey, flaky skin. This proved to be a case of ringworm due to infection with a Trichopyhton fungus. The disease should have been curable but the owner did not want the treatment carried out.
Ulcerative dermatitis refers to red, oozing, ulcerated skin. The affected area is often swollen and the bird often has an elevated white blood cell count, indicative of infection.
Ulcerative dermatitis can be associated with previous trauma, wounds, diabetes and certain intestinal parasites. The bird picks at its skin, creating the ulcers.
These sores are frequently itchy, causing the bird to pick at the area more. Bacterial and/or fungal infections may occur secondary to the lesions.
Treatment consists of trying to determine the underlying cause, cleaning the wound, using an appropriate topical and systemic antibiotic, and placing a collar to allow the wound to heal.
Lovebirds, cockatiels, grey cheeks, amazons and cockatoos are most often affected.
Skin Sores / Scaly Skin / Dry Skin / Itching Skin:
Several environmental and medical conditions can cause dry, itchy skin – such as Giardia or even Diabetes. When birds scratch themselves because of itching skin, the skin may become infected. The avian vet will at this point recommend a healing ointment, if needed.
Food allergies / sensitivities can cause irritated skin and this can lead to plucking or self-mutilation.
Relief Dry Skin:
Increase humidity: If the area is simply dry and scaly with no apparent infection (broken skin, redness, and seeping), the bird owner can try to keep the humidity up in their pet’s area. Especially during winters, when homes are heated, the humidity may be low causing dry and itching skin in birds. Ideally, the temperature should be close to 50% – but when homes are heated, it is difficult to increase the humidity to as low as 30%.
The use of a humidifier can bring great relief. If no humidifier is available, you can increase the humidity in your home by:
- hanging up wet towels and throw rugs in the bird’s area until dry – and then repeat.
- placing a bowl with water close to the heating system
- indoor plants hold water
- indoor water fountain
Aloe Vera: Additionally, provided your pet is comfortable with it, misting your pet with an Aloe spray (i.e., George’s Aloe Vera Spray Mister) often brings a lot of relief for a bird suffering from itching skin.
Offer bathing opportunities: Daily misting / spraying pets lightly with warm water or offering a shallow bowl of water for them to bathe in will help keep the dander down in the indoor environment. One has to remember that in the confinement of our homes, pollutants will collect in much greater density than they ever would in the wild. Especially in small, poorly ventilated spaces pollutants – such as dander, dried droppings and skin/feather mites – can be a major issue, daily ventilation (opening windows and doors) is the best and cheapest way to get fresh air into your home. If that is not possible — an air filtration system should be considered for those who are concerned about their pets as well as their own health.

You may also want to feed more foods with a high water content to your pet, such as juice fruits and high-moisture veggies; melons (including cantaloupe which has lots of beta carotene); as well as nuts and seeds – including ground flax seeds sprinkled on a pet bird’s soft food daily (half a teaspoon for larger birds, less for smaller) to provide the essential fatty acids and oils that are beneficial to his or her skin.
