Well if the age is right 3 years--and you are his third home the only place he probably feels secure is his cage--and that is making him territorial about it. This is JMO but I would not trust him to be sweet as long as he can see that cage--if you want to handle him take him out of sight of it and don't let him play on top of it. If need be use a dowel to move him away from it. These are not forever things but until he trusts you and settles in and knows he is staying.  Then learn to read his body and eye language--it seems that the bites come out of no where but there are always signals ahead of time--watch closely for them--and avoid the bite. Since he has already gotten your nose I guess I would definitely keep him away from your face? I never let my macaw get too close to mine as he is a face biter--

Give him lots of space and time to get used to you--and you him.      Katz

Oh another thing--macaws are very smart--Mine is cage dominant and will attack just to be put back into his cage--maybe why yours goes so willing?   Might want to try a T stand instead for time outs?          Katz

I also have a yellow collar and he is 15 months old.  He has started strutting and clicking his beak, I'm guessing he is starting the "preteen" problems.  He will bite and bite HARD to bring blood if I put him in his cage before he is ready to go.  He is still a sweetheart as long as I keep him with me, but If I try to make him go where he doesn't want to or do something (like sit on a playstand) he doesn't want to do, I have to watch my fingers and any other part of me that he can grab because it is going to be a hard bite.  I think I am his security or he just plain hates to be in his cage and alone.  Maybe Katz is right.  If he goes willingly or plain wants his cage, maybe the cage needs to be away from him when you are playing with him.

PS. My Calie does not care for men either.

One...two....three....FOUR!  That's FOUR YC mini macaws on Bird Brainz now!!!!! 

I have heard yellow collars are more calm than severes---I have a severe, he's possessive of me....if my husband is near me --he screams and runs trying to bite his shoes.  Lucky for me I have a very good natured husband.

 

I would suggest you towel him to get him out of his cage and take him away into another room where his cage cannot be seen.  See how he acts there.  Remember too this is breeding season and most birds are molting which makes them extra grouchy.

 

Also reward good behavior and try very hard to ignore bad behavior.

 

Good Luck.
