I have a 7 month old macaw. He happily steps up, loves to cuddle, and will follow me anywhere. Here's the problem. I brought him home in Nov. and about 2 to 3 weeks later he started biting. Always the arm he is perched in almost the same spot each time. The new addition to his environment was the wordy birdy so I removed it. For 2 days he didn't bite I thought the problem was solved, but not. He will bite/nip everday if allowed. I have been redirecting him with toys when I see that he is about to bite. Most times it works but sometime he tries to move the object to get to my arm. This is not the same as catching his balance. I had deep bruises all over my arm and he broke skin once. When he is very adamant about getting to my arm I will place him in his cage for 3 minutes then take him back out. After doing this 2 or 3 times he gets the message that if he wants to be out there will be no biting. But the next day we are back to square one. Please help I am doing something wrong.
