Why is my parrot aggressive and screaming after moving to my room?

A sudden change in behavior can sometimes indicate pain or illness, so a good first step is to have Mithu examined by your vet to rule out any health issues. If he checks out healthy, boredom or understimulation could be a potential cause. Spending more time together, offering a variety of toys that can be played with, chewed on, or torn apart, or even adding a playpen to his cage to let him stretch and be active may help.

It is very fortunate that Big Bird returned home. He should be examined by your veterinarian to diagnose any illness or injury sustained during his time outside. He may settle in after his experience but it could take time. Move slowly and speak softly around him. Offer praise and treats when he exhibits good behaviors. Be patient.

It could just be Mango is excited and trying to get your attention, or is bored and acting out as a way to entertain himself. Providing some extra enrichment such as puzzle toys to keep him occupied, treats, things to chew on, etc as well as letting him stretch his wings on something such as an outside of the cage playpen may help channel his energy a bit better. If he seems to have night frights at night even when covered, placing a nightlight nearby may help him settle and relax overnight.

Thanks for reaching out about Ahmer. If she was a hand-fed baby, maybe she associates people with feeding, and is hungry, not completely weaned. Do you see her eating, are feces present? Does she quiet when someone enters the room? Birds are very social and often don't feel comfortable when left alone. She might just need time to adjust. Monitor appetite and water intake through fecal and urine production. Good luck.

Winning the trust of a scared bird can be difficult. The book "A Guide to a Well Behaved Parrot" by Gary Gallerstein, is a great reference for behavioral training in birds. Continuing to offer treats by hand with slow, deliberate movements can help win trust. Good luck.

Cockatiels are extremely vocal birds, so it may just be that Cici is excited and very "talkative". Giving him some fun things to do such as adding in an enriching toy that requires concentration to open or play with, playing soothing music, or even moving him to a quieter location free of other pets and people may help him to settle down some. If he is housed with another bird, there could be competition over perches, food and water dishes which is causing stress, so adding extra in and making sure there is enough room for both birds may help. If he does continue screaming, or seems ill or painful in addition, a vet visit is always a good idea to rule out any pain or underlying health issues.

I'm sorry to hear Minty isn't doing well. It is possible that there is an underlying issue such as pain or injury causing the aggression, especially if it came on rapidly or is a complete reversal of their usual behavior. Other issues such as sexual maturity, being startled by something, etc may also cause a bird to become fearful or aggressive. Removing any nesting material, providing some fun toys to interact with and spending time bonding/offering treats when Minty is calm and relaxed, rather than nervous or aggressive may help. If the behavior continues or worsens, or you see signs of illness, seeking a vet exam is always best to rule out any potential issues that could be causing the change.
