My girlfriend and I just got back from a week long vacation. During that week, her 11 year old yellow fronted Amazon, Nikki, was boarded at a local shop that specializes in parrots. Ever since we've brought him home, he's been incredibly aggressive towards me.
For example, when he sits on his perch and I'm home, he'll pace, stare at me, arch his back and expose his wings to me in an agressive stance, and even lunge at me and bite me. Whenever he sees me, he is very vocal, constantly chirping (kind of growling, actually) and making a lot of noise. However, when I'm not at home (my girlfriend works from home, so she's there all day) he's a sweet, quiet, bird who enjoys scratches on his head and a slice of apple from her. He's eating normally, pooping normally, drinking water, all the normal stuff that might indicate something physically wrong.

What happened here? We had a good relationship before we boarded him - he would sit on my shoulder and preen as I worked on the computer, he didn't bite me, etc. He seems to have regressed in his attitude towards me - when I first met him, he wasn't like this!
Help! Emotion: smile

The bird is smart enough to know that Mike took the girl away for a long time and left the bird alone. Consider if it was not a bird but a four year old child who was treated that way by momma and her boyfirend. Birds do think somewhat like people, but when treated badly usually rather than sulking they attack instead. Boarding may sometimes be a necessity, but don't expect a bird to be happy about it.

The bird may come back to it's old self if a few days or weeks if you give it plenty of attention, but don't do this repeatedly or you'll have a vicious beast. Birds have long memories, strong emotions, and hate being ignored. Doing this is a much your girlfriend's fault as yours. The bird is acting normally.

Nice explanation, Lou. I guess I was being flip when I responded to this one. I forget that there are people new to birds that haven't experienced birdie punishment and a variety of other things.
The OP sent me a personal email telling me that my answer wasn't helpful and I tried to explain what you have said very well.

Joanne

Good answer, Lou!
Another scenario, they switched birds. It could happen.
