Bill (et al.):
To start off, nice photo Bill! At first glance, I saw the
brown-streaked breast, eyes set well forward on the face, and called this bird a juvie
Cooper's Hawk. (It is extremely unclear to me why anyone would call an obvious
accipiter with brown streaking on its breast an adult. I can see the
difficulty in distinguishing between Sharpie and Coop, but adults of both species
have orangish barring.)
The several Field Guides and Hawk ID guides I own state that a forward
set eye is a Coop field mark, yet some people have used this as a basis for
their Sharpie ID. In fact, in my 20+ years of birding I've found that this is
the most useless field mark authors mention.
That said, my own conclusion is that this is a juvie Sharp-shinned Hawk:
coarse brown streaking on the breast (Coops have finer streaking), a hint
of an off-white supercilium (Coops don't have this), and lack of any reddish
tint/orange buff on the face (which juvie Coops have), as well as points
others have made. But I'm willing to be talked out it.
Good birding, Mike
