We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
My $.02 ......have no problem calling the 'captured' bird a Cooper's. The breast plumage/coloring alone (if not a photographic anamoly) convinces me. The hood also typical. Size can't be taken into account - nothing to reliably scale it against in the photos. Have two sharpies and a frequent Cooper's patrolling the ridge on which we live here on Long Island. Efficient machines these accipiters. Not a creature is safe around our feeders. Ah, nature!
Happy New Year to all at Maggie's. You're all appreciated fer sure.
