I still haven't got any good pictures of our resident hawk. Though these ones have all the field marks: Slate colored back, White undertail, rusty bars on the chest, black and slate barred tail with a terminal white stripe and the fact it is snatching birds out of the feeders.
Hopefully, with some diligence I will get some good pictures.
