Levi was a very bad boy last night!

OH had him on the lounge, and my mum was sitting next to him, then my dad, then me.
Levi walked across everyone to get to me, then was making his way back to my OH but when he got to my mum he ran at her and bit her on the lip!

Luckily it didn't draw blood. Levi was told off and put straight back in his cage and ignored a hour.

I have no idea why he would do this? He knows my mum and is used to her. She looks after him when we are away, and gets him out and he sits on her finger fine. He's got cranky at her once before when she was trying to put him away but nothing major.

The only thing I cna think of was earlier on in the night mum was yelling at levi to stop flicking seed everywhere. I yelled at him too though, but he didn't attack me.

Obviously we don't want this to happen again as its not on, but we aren't quite sure how to correct it.

We said No, naughty boy and put him straight back in his cage, shut the door, and ignored him for about a hour.

He just went back in his cage and starting chatting away, laughing etc so I don't know if he even realised that he was naughty.

Edited to add - we've had problems with him nipping OH before when he's been with me, but we thought we'd fixed that problem has he hasn't done it for ages. Even when he used to do that though, it was a nip, when he went at my mum he moved so quick and just went at her to bite her, not nip her.

Maybe she was wearing or said something that he did not like. Morgan does not like it when I wear long sleeve shirts, every time I wear one he attacks me, the littlest thing tends to set them off.

Honestly, they seem to have multiple personalities some days. Clyde can be snuggling and saying "awww" and as sweet as pie one moment, and then snarl and nip the next moment, and I never know what set him off. Could she have accidentally bumped his tail? Clyde hates to have his tail touched, and that always gets a nip unless my reflexes are extra fast. Or did she make a sudden movement, maybe without even realizing it? They're awfully small and we're awfully big in comparison, and I think they're probably nervous about that.

No movement at all. She was just sat there watching tv with her arms folded so she didn't touch him or anything. It was like he just saw her then raced off my dad and straight over to her to bite her.

give it UP!!! the expression : "bird brain" applies...they just do what they do cause they do what they do..as i was typing this, my buddy'sonny" on my shoulder, just nipped my ear!!! [had her 7 yrs.]..there is NO rhyme or reason, NO pattern, so FORGET trying to figure it out...you will go nuts, and what ever you *think* the reason? be wrong, to boot. i think ONE thing WE forget: these birds were WILD..there may be generations that have passed, but there will ALWAYS be some genetic/ ancient thing with them, never to be removed...
one person asked why SUDDENLY after being a sweetie, one day MEAN, and biting..i have a theory: they sleep, have a nightmare where you are the bad guy, wake up, and cannot differenciate the dream from reality..it is just a THEORY....i am prolly wrong...like i said: trying to figure out HOW, and WHY they behave they way they do?? might as well try counting how many angels can dance on the head of a pin.
good luck.
