I was in the kitchen doing something one day and I heard him squeaking softly. It wasn't something I'd heard from him before, so I turned to look and he was attacking his tassle toy in his cage on his own. That's so awesome! He wouldn't touch it before.
Sometimes when I'm flirting with him, I'll puff at his tummy. It's to blow away dander and stuff. Sometimes, he spreads his wings out when I do that. =) He also bends to his left so his body is still upright but his head is upside down. His wings will be spread out and at a 45° angle.
He looks like a retarded bat. XD
I tried to get a picture, but he stopped when the camera came out. I've started saying, "Big Black Angel Wings" at him when he does it so maybe he'll associate with that and learn to do it on command =)
