My Girl friend has a greenwing macore its very big and very loud, she is a vet nurse and has a well thought through diet for it loads of toys ( that he destroys in seconds) and a great cage. Recently though she says hat he is displaying more & more aggression towards her ( screeching snatching and biting, flapping and lunging if out of the cage and banging the door in the cage roof. He's about 7 years old and his behavior seems to have deteriorated over the 12 months we've been together, are birds capable of jealous? as we spend more and more time together. We have tried ignoring him when he screams and bangs but she is concerned about the neighbors. Interestingly he is less aggressive to me he jumps to a lower purch and bobs when I approach him. I haven't done anything nasty to him to elicit this behavior, but when he has been aggressive to me I have stood opposite his highest purch and flapped my arms so I look significantly bigger ( I'm 6'2'' easy for me, my girlfriend is only 5'3'' thats below his purch height). If out of the cage he doesn't chase me either but he will chase my girlfriends nieces and brother screeching with his wings out very aggressively who run away from him, I didn't react to this so doesn't bother me now.
I have read articles that say dominance isn't important and also that you should only use possessive re-enforcement but we are getting to the end of our tether any suggestions advice or help, I was considering spraying him with cold water like I would a naughty cat (thats in desperation).
