Hi, Gary!
Accipiters have always challenged me, but I'm pretty sure that your photographed bird is an adult Cooper's Hawk. My first impression was Cooper's, and I realized why: it shows some of that "capped" appearance and squarish head shape that makes it look a bit "bulkier" unlike the more "cute" Sharp-shinned Hawk. It's tail is rounded off, which I'm pretty sure is the mark for Cooper's as well (Sharp-shinned would be flatter, I believe). That's a very nice photo!
That's my nickel and dime at least.
The birds are happy, and so am I
