thank you very much for your reply, this does help me open some new avenues to try and solve this issue.
I do think that Buddy (the bird) is getting more attached to my boyfriend, so this could be it i guess? But the bites only ever occur when i am alone with him, and my boyfriend also sometimes gets bitten in similar circumstances.. so I don't know what to make of that.
often, Buddy will land on my hand, bite (draw blood) and then start flying around the room, and swooping me; I don't think this is a way to amuse himself because he gets all pinpointy eyed and hissy.
I've been trying to distract him with training when he gets like this, to get him back into cooperation so that I can put him in his cage. this mostly works. I've had to get him in the cage wrapped in a towel once though. When he's in this crazy mood he will try to attack me though the bars too. He is also very teritorial with his cage; i can not change the food bowls when he is in there, have to do it when he is in another room.
This is really a morning problem. the rest of the day, he tends to be gentle.
I'm meeting a lady from our local parot rescue soon, and hoping that she can help me with this.
