Sharp-shinned?

Looks good for a Sharp-shinned. In the 3rd photo you can see it has a dark nape.

Awesome. I saw that, too, but thought it was too good to be true. My first at last. Thanks for the confirmation!

I think this is a Cooper's.  To me its tail appears graduated, its nape appears light, it is bulky, and the front edge of it wings are very straight.  I have been wrong on these before, though...

Darn. Thanks all. So a Cooper's has straight leading edges to its wings and a Sharpie has what...points like this guy from this morning? (Sorry, terrible weather for action shots.) But I was pretty sure this was a Cooper's...:unsure:

This looks like a Coop as well. Sharpies have bulging secondaries and their wings looked pushed forwards at the wrists. As a result, the entire wing seems to have a bit of an S-shape.

The dark nape isn't much use on a flying bird, I've found. When they're flying, they're looking straight ahead, which would be straight up on a typical perched bird. So the feathers on the crown and nape get squeezed together. I've always found the whole dark vs. light nape to be of most use right at the rear edge of the auriculars - on Coops, they blend into the nape, and on Sharpies there's a nice contrast between the nape and the auriculars. Once you see it, it's hard to mistake. But I wouldn't bother using that on a flying bird -- between the odd angle of the head and the distance you're usually at, it's not much use then. And there's other things to look at on a flying bird.

Sorry I misled you on this. I'll agree with psweet and the others that it's a Cooper. My bad! :unsure:

Worry not Bird Brain. I think everybody has made wrong calls on these from photos. I sure have!

In this case I would have called it a Coop based on the big head (visible in the first and third photo) alone. But got here late so I can just agree with psweet and not risk being wrong again.

The other factor here is what psweet called its "bulk." To me this one looks so exceptionally 'bulky' that I think it could be correctly called a Fat Hawk.

No worries at all, Bird Brain! I thought for sure I had a Sharpie before I posted. Alas, just a fat Coop. At least I know what to look for in the wing to discern (or try) one from the other now. I think once I see a Sharpie in flight it will be a little easier. Thanks again, everyone, for the awesome tutorial!

 Just another tip... when making an ID between these accipiters(and another 2 very similar species) it is always better to use a combination of field marks instead of just one to make the ID as there is usually some level of variation or overlap in many of the ID marks.

I'm determined to find a Sharpie in my archives, and I think I finally found one based on the head/wing posture and size differences of these two. Bird on the left (Sharpie?) shot in Middle TN Nov 2011. Bird on the right (Cooper's?) shot in Middle TN May 2017. Thoughts?

I agree with your IDs of these.
