I am not a hawk expert either! But I agree with Joe. Adult Cooper’s based on the head shape, eyes, tail, and horizontal breast streaking, etc. I wished I had the photo in PhotoShop so I could lighten it a bit. Would guess that the breast would tend to show a little more rufous orange in the streaking and not quite as dark brown, but don’t know that. Didn’t try it since it is a private photo in pbase.

Thanks. This appears to be an adult (based on breast pattern; jury would show vertical streaks) Cooper's Hawk, based on proportions of bird, rounded, not squared off tail, position of eye in head, etc. I have never seen one this dark! Off hand I would call it melanistic. Even the terminal tail band is dark and it is usually white. I don't think they have pale and dark "phases" like buteos. I will be intrigued by comments from raptor experts.
