Thanks, all. It was nice, for once, to have a clear-cut identification - thanks to the hawk's hanging around and posing, flashing all of the ID tips. Usually I'm scratching my head and fussing over an ambiguous photo. Claire

BN, It's a rare day that I disagree with you on any ID, but this juvenile hawk has too many uniform upper chest markings to be a Red-tailed. This is a juvenile Red-shouldered Hawk. The chest/belly pattern fits that species perfectly. I'd point out the barred primaries/secondaries on the folded wings, but, alas, the tree trunk blocks that view. I am certain the barring would be there. I am certain it's a Red-shouldered. BN is correct, though, in distinguishing this Buteo from an Accipiter (Cooper's/Sharp-shinned/Goshawk). The wing tips come too close to the tail tip. This post was edited by TMFF on Thu, Dec 12, 13 at 17:22

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.

Yes, your bird was a juvenile Cooper's Hawk. Looked like a big, nicely marked one. Sorry it took so long for someone to respond; I hadn't checked this forum in some time. Cooper's Hawks are Accipiters and Accipiters are built for ambushing and chasing birds around and about. I have read they do occasionally take smaller squirrels (such as Eastern Gray), but the vast majority of the time they stalk bird feeders to take birds. The squirrel probably felt safe challenging the Cooper's for that reason. Had that been a Red-tailed Hawk hanging around, there may have been a different reaction by the squirrel....
