We have had our green cheeked amazon for over 20 years since he was about 8 months old. The first 10 years were pretty great. When we moved into a new house about 10 years ago his behavior changed. He began screaming a lot and then biting my husband. They used to be good friends. Now I am the only one who can handle him. In the morning he is loving. We cuddle he nuzzles with me and makes cooing noises. He becomes Horrible in the afternoon. He screams non stop. I move him to different rooms to no avail. If I give him a treat he will go to his bowl and eat it while screaming. I've also discovered that if I use kitchen appliances like a mixer, that sets him off. The screaming while I'm cooking is so distracting that I cut my fingertip off a few months ago. The only thing that works is covering his cage. We never covered his cage. But now in the late afternoon or evening I put him in his cage and cover it. He will initially lunge at me, but then settle down make kissing noises and eat. Anyone have any ideas on why he is screaming and behaving this way and now to deal with it
