Bird behavior can be complicated, but one thing to understand is that the parrot always has a reason to bite, and they always give some warning. The key is to understand his behavior and recognize the signs before anyone gets bitten. You have to understand wild parrot behavior to understand why your pet bird does what he does. With wild parrots, a mature Macaw would have one mate, and would have little to no physical interaction with flock members. They live in flocks mainly for protection. But during breeding season, each pair establishes a territory and they keep other flock members away from their mate and nest. So basically we want our pet birds to maintain flock behavior well past the age when they would normally stop having physical interaction with flock members. In your situation, your macaw treats you differently because you both behave differently with him. It sounds like your wife gets him excited and wound up – parrots love being loud and boisterous. But then she gets him too wound up and he kind of short circuits and acts out. But why the bite? If you are present at the time, then most likely he is biting out of jealousy. Maybe he thinks you are going to take him from her, and when he can’t reach you to bite you, he bites her instead. This stems from natural mate behavior – if a rival bird gets too close to a bonded pair, especially when nesting, the rival will be attacked. But also, the male will sometimes turn on his mate and drive her back to the nest. Since your wife was carrying him at the time, if you weren’t around, maybe she walked past something that alarmed him or maybe he thought she was about to put him back in his cage and he was having too much fun. This still comes down to understanding body language and recognizing when he is going to bite. It is unfortunate that this bird has already been passed around to different homes. I do feel like you can work with him and keep him in your home, but your wife needs to be on board, too. She first needs to understand not to take it personally – she is hurt physically and emotionally. Parrots act on instinct, not on feelings.
This is a great question about an unfortunate and all too common situation. We will be having our monthly Pet Bird Behavior Q&A Webinar this Friday. I would like for the behaviorist, Chris Davis, to start the webinar with this question. If you can both view live, it’s free & I’ll post the link below for you to register. If you can’t watch live, please register anyway. After the webinar, we send out an email with the link to the webinar recording on Youtube. Chris has this wonderful way of explaining behavior and how to better communicate with your bird. Please let your wife know, because I think she will feel better and have a better understanding after she watches Chris’ response.
