What the HE double hockey sticks is this?

Some interesting replies here. LOL
Some things I know about this bird.
1. It can fly
2. It is very tame, seeing as I walked within 3 feet of it.
3. Way to big to be any quail I ever heard of.
4. No baby birds around here this time of year.

I thought it might be the result of a careless female pigeon and a blind zebra.
