i have an 8 yr. old blue front amazon, and i am his only owner. He talks, loves to sit on my shoulder, lay in my lap on his back, go for rides in the car, and has never had a health problem. We used to be a huge family with lots of other parrots, but due to a nasty divorce, he and i have been alone for the last 5 years. The problem now is, i was given an umbrella cockatoo a week ago, also 8 years old, very sweet, in excellent health......and my Amazon has gone ballistic! he has bitten me viciously 6 times in the last week, lunges at me, tries to attack me, is constantly "displaying" at me, and hasnt said any of his words. he chatters with the cockatoo, andhas investigated her cage, and does not harm her at all, but i can no longer approach him. their cages are in the same room, next to each other. i will not get rid of the cockatoo, and i dont want to get rid of my Amazon, but i cannot keep getting this deep vicious bites. can anyone suggest anything? it would be greatly appreciated.
