Why is my 8-month Amazon parrot losing weight and unable to fly?

Weight loss in birds has multiple causes (parasites, poor diet, GI disorders, etc.). Ideally, your bird should be physically examined by your veterinarian or an experienced avian vet to diagnose and treat any underlying medical causes. Blood work, x-rays and a fecal exam may be recommended.

Nutritional deficiency, liver or kidney disease, intestinal parasites or bacterial, viral or fungal infection are all possibilities. An exam with your veterinarian or an experienced avian veterinarian is strongly recommended to diagnose the exact illness or injury. The vet can administer supportive care if indicated. Offer a commercial pelleted diet moistened with warm water or a hand feeding formula to stimulate his appetite and get some nutrition into him. Keep him warm and as stress free as possible until he sees the veterinarian.

I would recommend getting a small scale (possibly a food scale) and weighing ZR every day for a week. IF he weight decreases but goes back up I would not be to concerned. IF you find his weight decreases over the week but he is still eating I would recommend taking him to the vet for blood work. weight loss could be a sign of illness in ZR. With his young age I really think it is most likely a normal change in weight due to growing and maturing

I'm sorry to hear Sky isn't feeling well. Unfortunately, those are very general signs of illness that can be caused by a number of things, so seeking veterinary care is best to help narrow down the cause and get her feeling better. Illness, infections, parasites, malnutrition, etc can all cause a bird to become ill and lethargic. Until you can get to the vet, you can move Sky to a separate hospital cage that is kept warm if she is kept with other birds, with easy access to food and water, and in a calm, quiet location. This may help her some until your vet can determine the issue.

Unfortunately, those are all very vague symptoms of illness that can be caused by any number of things including infections, diseases, parasites, malnutrition, etc. It would be best to bring Mitthu to your local vet for a complete exam to try and find out what is wrong. They may suggest additional tests such as bloodwork or an X-ray to help find the problem. In the meantime, keeping him in a warm hospital cage that is separated from any other birds and with easy access to food and water in shallow dishes with low perches may help some until he can be seen by a vet.

Balance issues and falling off the perch are not normal behaviors, so if your Quaker is having trouble staying perched, is acting confused, or is unable to eat or drink properly I would seek veterinary care ASAP. Underlying issues such as muscular or neurologic disease, illnesses, infections, nutrient deficiencies, etc can all cause problems like this to happen, so ruling them out is best. Make sure to keep offering him a balanced diet, and if you suspect illness, keep him warm and separated from other birds until you can seek veterinary care.

Thanks for reaching out about Kiki. Did the veterinary perform any diagnostics tests such as blood work or radiographs? Age can prevent flying as the bones become weaker or muscle atrophy. Determining the cause of the weakness might provide an avenue of treatment. Good luck.
