So it is a very special case here. My mother bought a 1.5 month old gray parrot. He was an adorable and very calm bird.
At the age of 5 months my brother started playing with him aggressively by distracting him, poking him with things, putting fingers in his cage and then pulling them out when the bird started attacking, etc. The parrot started to bite my hand every time I approached him, not "escaping only" bites and very hard. Now that my brother has stopped irritating the parrot, I want to stop this biting issue.
Current situation - the parrot doesn't fear me, and while outside of the cage he will sit on my shoulder most of the time. If I leave the room then he will fly to me if he wasn't already on my shoulder. But my hand approaching him will provoke an attack--he will violently bite it and at times even inflict a bleeding wound--and when I take my hand away from him he will instantly chase my hand to continue biting; after he's done he will usually return to my shoulder.
It's hard to feed him from my hand but it's possible. It is nearly impossible to make him sit on a hand, except when he is taken out of a cage. It is also hard to train him.
My guess is that he bites everything that he doesn't like.
How can I prevent this behavior?
- Current age: 7 months old.
- Parrot name: Kelvin.
- Origin: bought from a breeder, without full feathering, hand-feed by me using a syringe until the age of 6 months old, then he started to refuse hand-feeding.
