Harryshoe's image is an adult Cooper's. You are correct, kathy9norcal. Note the tubular chest, thick legs, squared head, "Roman" nose, and eyes that are set back from the bill. Tail tip is an unreliable markon a perched bird (so I have learned through experience) due to feather position/wear. Also, on your Cooper's, second pic down- this adult bird has a pale nape to the neck. That is a good mark for a Cooper's. An adult Sharp-shinned has a dark nape of the neck that makes the Sharpies appear "hooded" rather than "capped". Cooper's appear capped.

We have had a pair of Cooper's Hawks nesting in our neighborhood for the past two years. I like watching the hawks, and don't want to harm them in any way, but they have completely driven off (or eaten!) all our songbirds. Two weeks ago, we had scores of sparrows, chickadees, and juncos, as well as 3 pairs of cardinals at our feeder. There were so many birds that they were waiting on the railing adjacent to the feeder for their turn -- and we have a large feeder -- 12 cup capacity with at least a dozen feeding ports. We were refilling the feeder every day or every other day. Five days ago, the songbirds just disappeared overnight -- went from frequent refilling of feeder to no activity at all for last four days. This morning, we saw the Coopers Hawks for the first time this season, although they may have been in the area for a time. I can't believe they could have devoured all the songbirds, but they've surely intimidated them to the point where the seed level in our feeder has remained unchanged for four days. I was surprised when the hawks first showed up, as I really didn't think they'd nest in town. (We live in residential neighborhood of medium-sized lots in a relatively small town.) Our neighborhood has the usual amount of "commotion" that goes on in a neighborhood with young families, working couples, and retirees -- vehicle noise of frequent comings and goings, usual noise made by kids and pets (mostly dogs), and seasonal power equipment (mowers, snowblowers). While we don't live in an unusually noisy area, it's by no means quiet either, and the noise level doesn't seem to deter the hawks one bit. Last summer, I noticed that I didn't see or hear the hawks for a few days when a flight of crows stopped in our area for a day or two. We also have at least one owl (not sure what kind, but I suspect great horned owl by its calls), which we were hearing nightly for most of the winter, although I haven't heard the nightly hoots for a few days. Although I have no great love for crows, I'd like to see a few more around, as they seem to keep the hawks at bay. What else can we do to encourage the hawks to "move along" and leave our songbirds alone? As I said, I have no desire to harm the hawks in any way; I'd just like to see them relocate.

These guys are very sneaky in my yard. The only time I see them is when they are leaving one of my trees. I have yet to spot one while it`s perched in my trees. Very nice photo!

This is absolutely an adult Cooper's Hawk with the dark "capped" appearance to the head and also the grey auriculars (cheeks). Tails really cannot be assessed from the dorsal view (Cooper's show graduated lengths and Sharp-shinned show even lengths, but this is best assessed from the underside of the tail). Sharp-shinned Hawks do not show grey cheeks, either. The grey cheeks are exclusive to adult male Cooper's Hawks, and the very bluish slate colored back and wings further support male (female adult Coops are duller).
