My parakeet's feathers are deteriorating. Why are they falling out?

Thanks for reaching out about Bangaram and including a photo. Psittacine Feather Destructive Behavior is common in parrots, but the difficulty is acquiring a cause. Stress/behavior is common a nd can consist of breeding, nutritional or environmental stressors. Diseases can also lead to pulling feathers including infectious diseases (viral, bacterial), metabolic disorders (liver, renal), skin diseases and others. A veterinary visit is recommended to assess and try to determine a cause. Diet and husbandry practices need to be reviewed with a veterinarian experienced with birds. Some diagnostic tests will probably be recommended and necessary to come to a conclusion. There is no topical medication that is going to cure or even stabilize this condition. Good luck.

Thanks for reaching out about Zulekha. A veterinary visit is recommended as a disease called Psittacine Beak and Feather Disease is a good possibility. This viral disease is potentially contagious to other birds and there is no treatment. A diagnosis needs to be made. Other concerns are liver, renal, polyoma virus, just to list a few. Good luck.

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 Blink and including photos. Feather picking can be due to external parasites (mites, lice), bacterial or viral dermatitis, nutritional deficiencies, metabolic disorders (liver, kidney), endocrine problems and stress. A veterinary visit is highly recommended to assess and provide a diagnostic/treatment plan. Ensure that heat support is provided due to the loss of feathers and ability to regulate the body temperature. Good luck.

Thanks for the picture and reaching out about Kore. This could be either a fractures feather, possibly weakened by a nutritional deficiency. Protein and several vitamin and minerals are important for feather strength and integrity. Check to see if the calamus is still in place inside the follicle. Usually the birds will chew it and work it out. Another possible condition is one of a few viral diseases that can damage feathers. If the condition continues, a veterinary visit is recommended.

Thanks for reaching out about Billy and including photos. Viral diseases, nutritional deficiencies or metabolic disorders are all possible. Stress can cause feather destructive behavior. Some external parasites are only on the animal during the evening hours therefore are difficult to identify during the day. A veterinary visit is recommended. Good luck.
