Yard Bird Species #57

We looked out our living room window this afternoon and saw a dark shape in the tree where we regularly see a variety of hawks and falcons. Too big to be a Merlin or Kestrel, I dismissed it as a small RTH. But then my hubby asked, "Do red-tails have dark cheek patches?" So out came the camera for an ID shot (and crappy ID shots, at that), and this was the result:

Well, hello there, Mr. Peregrine Falcon! Wasn't expecting this guy at all. Quite a nice addition to our yard bird list. :)
