Hawk at the Zoo

Ok, I'm not even going to try and ID this hawk! I was lucky to find it just a few feet away in the Owls' aviary at the Calgary Zoo a few days ago. I took SO many photos of it, though I knew that the light was beginning to fade. Well, I now have a lot of photos to delete, but managed to rescue this one and maybe a second one! Oh, for a camera that is good in low light - sigh! Possibly a Rough-legged Hawk.
