Why is my Quaker parrot's tail turning brown? What should I do?

Thanks for reaching out about your parakeet and including photos. Was he ever tested for Psittacine Beak and Feather Disease (PBFD) and Avipolyoma virus? Nutrition deficiencies, metabolic disorders (liver, renal), hypothyroidism and other endocrine problems, all must be considered. A veterinary visit is recommended to assess and provide a diagnostic/treatment plan. Review and discuss diet with the veterinarian during the visit. Good luck.

Thanks for reaching out. Diet can have an affect on pigments of the plumage. An only seed diet lack multiple vitamins, minerals and nutrients, and is a poor diet. A wide variety of vegetables and avian pellets should provide an adequate diet. If continued to be concerned, a veterinary visit is recommended to assess and provide a physical examination. Good luck.

Thanks for reaching out about Mango and including a photo. There are a few possible causes for this. Nutritional deficiencies and some viral disease can cause improper pigmentation and a veterinary visit is recommended to assess. But, if you pet him a lot in this region, the oils from our hands can sometimes elicit this change to black but to loss of pigmentation, and this is not a medical concern. Good luck.

Stress and diet can both contribute to feather health and coloring. As long as your bird is behaving normally otherwise, there is likely no cause for concern. Monitor for lethargy, loss of appetite, loose droppings or excessive feather loss (not due to molting). These are symptoms that should be addressed by your veterinarian or an experienced avian veterinarian.

Thanks for reaching out about Rio and including a photo. Nutritional deficiencies, bacterial infections of the feather follicle, some viral diseases, are all possibilities (among others). With how "pinched" to tip of the feather appears, concerns over Psittacine Beak & Feather Disease, should be ruled out. A veterinary visit is recommended for testing and a nutritional consult. Feather growth requires a substantial protein expenditure so plant based proteins (beans, sprouted seeds, legumes) should be a component of the diet. Good luck.

Thanks for reaching out about Sky. Feather loss can be due to poor diet, stress, over-preening, external parasites, skin infections, metabolic disease, viral disease and more. Research and correct the diet birds do poorly on an all seed diet. A veterinarian is probably needed to exam and recommend diagnostics/ treatments. Good luck.

Thanks for reaching out about Pudge and including photos. The black around the rim of the back feathers are probably stress bars. Poor feather quality can be due to dietary deficiencies, metabolic disorders (liver, renal), infectious diseases (viral, bacterial) and others. A veterinary visit is recommended to assist with a diagnostic/treatment plan. Diet should consist of pellets, a proteins source, a wide variety of vegetables and few or no seed. Good luck.
