Unlearning bad behavior.

[parrotntn]

Cleo has a bad learned behavior. She wants to bite/beak hard SOMETIMES when she steps up. If she is in a place where she needs to be rescued, she hops eagerly onto my hand. Otherwise, she'll nip and run from my hand/finger OR the perch when approached.
She was rescued from a hamster cage in a bad petstore in Indiana so there is no telling what her history is.
She is very loving otherwise, allows me to hold her head in my hand and eats eagerly out of my hand. ROLLS on her back for some belly scratching, etc. as long as it's on a perch.
I've been able to clicker train her to bring a ring and put it in a cup, to wave, and some other things. But I cannot UNTRAIN her from this bad habit.
I will say that today I tried something a little different with the perch. I more or less "scooped her" onto it. Instead of bribing her onto the perch, I just moved with it quickly and got her onto it. Basically not giving her time to repeat that bad behavior. It actually worked pretty good.
I'm just looking for any other success stories.

Mark.
