I was told to take his cage away because the people at the rescue said they have seen this before in greys and they called it "cage defense". The funny thing is, he will step up from anywhere but his playstand and his large cage. If I set him anywhere else he will step right up.

I adopted a grey last January. He is 13 yrs old. Always been very gentle. He has always stepped up. Suddenly, I had to take his large cage away(on the suggestion of the rescue I got him from), because he would not step up from his cage. Now he will not step up from his playstand unless I turn all of the lights out at night. Then he calls me (he calls me girl). He steps up fine to go to his playstand with the lights out, he steps up fine from his (travel)nightime cage. But once he is on his playstand he bites the ***** out of me. I have tried to suck it up and take the bites to get him to step up, but it is not working. Any ideas?
