LOL!
She reembles an Umbrella Cockatoo in the second image.
One specifically named 'Patches'.
Patches would hop straight up and down on his perch, and laugh maniacally.
When told he was making a fool of himself, the bird would reply with 'Yup!' and continue his antics.
He'd also reach out of his cage with one foot and try to grab a hold of passers by, he wanted the top of his head scritched.
*chuckle*
The look reminded me of him.
Pretty bird, I can see why your boy is protective of her.
Mine does some of the same things! This figure-8 "Ray Charles" head swing when she's happy, or she faces towards the outside and just bounces, bounces and bounces! She follows the dogs around the house like she's one of them.
Oh, and you know you can cross Umbrellas with Moluccans to get "Mobrellas"?(I kid you not!)
