He also looks inordinately pleased with himself...what had he just destroyed?

Have you had him sexed? He does have a masculine look. It's hard to make a good guess from one picture, but I'd guess "male." I guessed the sexes of my babies fairly accurately. The males tended to have larger bones and beaks and to have darker feathers and darker skin tone. Of course, the skin gets covered by feathers and the face turns white in both sexes.

Once again: what a handsome bird!

I'm always amused by what greys pick up. You can try to get them to say something until you're blue in the face and if they don't want to learn it, too bad. Then they can hear something else ONCE and it's committed to memory. So, he's the great Cornholio? Do you give him TP for his bunghole? Bungholio!

A red-tailed hawk? I used to say the same thing about my babies. When they were little, they all loved for me to cover their heads with my hand and gentle stroke their red tail feathers in a pulling motion. They'd be clustered in my lap with their little butts in the air, waiting for their turn. I wish I'd taken pictures of that, now. My Amazon HATES having his tail touched, so I was surprised to learn that little greys love it. I never met a baby grey that didn't like to have his tail gently pulled. My little red-tailed hawks...sigh.
