This is one of the most interesting raptor ID challenges I've seen in a long time. BWHA seems far-fetched (I've never seen one perched up). Accipiter seems more likely. Goshawk? Whatever, it's a juvenile. Hmmm….this is fun. Can't wait to hear from Bud.

UPDATE: Between Tweeter comments (some made privately) and Flickr comments, I have about half Broad-winged Hawk IDs and half Cooper's Hawk IDs, but a Flickr commenter just suggested immature Northern Goshawk, which looks good, too! Awaiting final determination from Bud Anderson. Thanks for all the input, everybody--hawks are hard!

Alex,



I would agree with your first assessment, that it is indeed a Cooper's Hawk. Look at how narrow the final black band is on the tail, and compare it to photos on the internet of Broad-winged Hawks, with broader final black bands, and may be fewer black bands. That said, I am not certain it isn't a Sharp-shinned Hawk. It would be helpful to get an idea of the size, crow-sized for a Cooper's , big jay sized for a Sharp-shinned, but the tail on your photo shows the better rounding at the end, that is more a feature of the Cooper's Hawk, while the Sharp-shinned is a bit more squarred at the end, at times with a better defined notch in the center. Also, we don't get many Broad-winged Hawks in our area, which is partly why I always want to know where a photo was taken, ideally with some habitat information..

In Sep 2014 I took a photo of a hawk at Magnuson Park in Seattle and posted
it on Flickr as a Cooper's Hawk. Recently a birder commented that he
thought it was a Broad-winged Hawk. I thought that unlikely but am now
confused by his field mark comments. The photo and comments may be found
here:

If the experts can weigh in, I'd greatly appreciate it.

Thank you,
