I think only Cynthia saw it in person.. Do you think that a female Cooper's hawk couldn't be mistaken for a Sharpie even in photos? That's good info on the size difference between male and female Coopers vs. Sharp-shinned. If you saw them side by side I guess it would be easy to tell! Or even chasing a Blue Jay!Thanks!On Wed, Jan 14, 2015 at 12:04 PM, david merker <[log in to unmask]> wrote:Hi
I'm going with a male coopers hawk. The way I tell is 1. Someone thought it might be a sharpie, that makes it a male, because female coops could not be mistaken for a sharpie. 2. it has feet that actually look like they can do some damage, sharpies feet do not have that look. Also its broad across the shoulders. Sharpies are slight across the shoulders
"small male Coopers Hawk can be the same size as a large female Sharpie".
Reality is that they could LOOK (in flight only) to appear to be about the same size, in reality (measurements and weight), they aren't that close. The small male coops out weighing the large female sharpie on average by almost 100g+. Average female ss 167g Average male coops 343g.
The low mass for male coops is no lower than ~300g
The highest mass for female sharpie is no higher than~202
Thats my take on it :o)

To: [log in to unmask]The shoulders look massive.. I've seen a sharpie chasing a Blue Jay and got pictures, and the Sharpie was NO bigger than the Blue Jay! Just from looks I guess it's most confusing because a small male Coopers Hawk can be the same size as a large female Sharpie.. But the sound seems like a good clue! I think of Coopers Hawks as saying "Kek-Kek" and Sharpies something more like 'Que Que".. but don' t have much experience comparing the sounds..**************************************************************** To post messages, send e-mail to: [log in to unmask] Set your e-mail application to PLAIN TEXT ONLY to post messages.

I think there is some chance this bird might be a Sharp-shinned Hawk. I based my decision on what looks like a larger head, and perhaps a larger bird, a longish rounded tail, and, probably a young bird as the eye is still yellow and the coloring is brownish. The angle of view in my pictures could be deceptive. I would expect an expert might even have more to say. I also hear some "kik" calls -I interrupted this birds meal and got scolded!Interesting that Blue Jays are getting hit-we have many of them this year-sometimes 17+ at a time. That is unusual where I live.Cynthia Crawford

Last Friday morning, the 9th, we watched for almost two hours as a hawk calmly devoured a hapless blue jay underneath a feeder we hang from an apple tree. We don't have a decent camera but were able to spend a good bit of time with binoculars and scope watching the event. Based on white speckles on the scapulars, we tentatively identified the culprit as a juvenile red tail. But Cynthia Crawford's post and pictures this morning sent us back to our guides and field notes. Based on a closer reading of bird behavior and feeding habits and a review of our field notes, we now believe what we saw was a juvenile Cooper's Hawk, particularly given that one mark we noted clearly was that the tip of its bill was dark, almost black. The only remaining doubt is that the tail of the bird we saw didn't look as long as the guides indicate for the Cooper's. But Cynthia's pictures resemble the bird we saw and, bowing to her superior expertise, we'll revise our log. We need to get a decent camera!Either way it was a dramatic event. Nothing left at the end of the meal but a few feathers — not even a stray bone. Felt bad eating breakfast while this was going on outside the window, but the chickadees continued to frequent the feeder during the latter part of the feast, so we weren't alone.This listserv is enormously useful for those of us who are what might charitably be called "emerging birders." Thanks to those who post to it and maintain it.**************************************************************** To post messages, send e-mail to: [log in to unmask] Set your e-mail application to PLAIN TEXT ONLY to post messages.
