Interesting comparison! Thank you so much for your message.
They said smaller than a crow so I went to Sharpie.
Also the tarsus, you can see in that one photo where it is erect is very thin and delicate. If it is a Coop it’s a male for sure. I recently held a female juvenile Coop and she was way bigger than this bird, beyond usual comparison to the tiercel.
Learn something new every day!
Take care,
Melanie

I think this is may be due to a somewhat more prominent brow ridge on Cooper’s. Male sharpies are fairly easy to ID from size alone: barely bigger than robins.
