Why is my Amazon parrot aggressive and cocking its head after being outside?

Some neurologic, muscular, diseases processes, and nutritional issues can cause similar symptoms. It would be best to bring Parrot into a local vet ASAP to have him examined, bloodwork taken and possible X-rays taken to look for underlying issues and provide treatment. In the meantime, making sure he is kept calm and quiet, can still access food and water (and is eating a balanced diet of seeds and pellets for budgies) and separating him from any other birds in the cage can help him feel more comfortable until the underlying cause can be determined.

Your bird was on her own for six months, it's normal that she has essentially gone wild. It will take time and patience, but if you tamed her once, you can do it again. I do recommend getting her seen by your vet to assess her health and make sure she's okay.

If he continues to act abnormally, I would be concerned about an injury and recommend he visit his vet. A loud scream definitely doesn't mean he hurt himself, but sustained lack of interest in play would make me very concerned. I hope he continues to return to normal.

Thanks for reaching out about Summer. Parrots sometimes find change difficult. The first thing that should be tried is returning Summer back to the previous location, then bringing her out when you are in your bedroom. Gradually, as she becomes more acclimated to your bedroom, then you can try moving her cage into your room. Good luck.

Thanks for reaching out about Muthu. Stress and change in routine can be the cause, but so could infection of the syringe or systemic illnesses. If acting off in any other manner, a veterinary visit is recommended sooner than later. If only stress, winning his trust again and calming down the routine could be curative. Good luck.

That is very odd behavior. If Salyt is unable to hold her head in the proper position, seems in severe distress, or is otherwise acting ill it would be best to have her examined by a vet in person as she may be injured or ill. It is also possible she was just very excited and flapping around to show her excitement, however she would be able to return her head to normal after and should still be active, eating, drinking, etc. Keeping an eye on her, and if she seems ill or doesn't return to normal, seeking vet care is best.

It's possible Mitthoo was injured or became ill from something while outside. It is generally not a good idea to let birds roam free outside if they are domesticated, as they may become ill from other wild birds, spread illness to wild birds, or become injured. Since she is acting unwell, it would be best to bring her to a vet for care and to rule out issues such as parasites, injuries, illness, etc that could be causing her symptoms.
