Several people have asked me about this accipiter on the Oregon bird list, so I thought I'd just comment on the blog. And, if there are raptors being debated on local bird lines in the future, I may just do the same instead of giving my ID behind the scenes. This bird was photographed by Jack Williamson, a beautiful photo and great documentation. Here is the link to the photo, made public, so I'm assuming it is OK to post it here...but if not, I'll take the blame:

This bird in question is absolutely an adult Cooper's Hawk for the following reasons:
- Very long tail with a broad, white tip.
- 'Large' head with blackish cap and contrasting pale nape (also smallish eye appearance). Sharp-shinned have blackish heads and napes that blend in with the upperback.
- Paler bluish upperside (as opposed to slaty) and grayish cheek make it a male (the reason it is more difficult to ID than if it were a female Coop). Many males in their first adult plumage have rufous cheeks...and this bird has hints of rufous and a pale eye (so, likely it is a bird in its first adult plumage, but not definite).
I am working on an article on this very subject, but too busy to get it together at the moment
