Chicken hawks

By which we do not mean the political or the gay. We're more concerned about Cooper's Hawks, Sharp-shinned Hawks, and Western Red-tailed Hawks (in that order above). While Cecile was in Spain, Jesse saw what looked like a huge and hawkish dove over the coop. Our neighbor Karla, who can see the coop from her house, had warned her about it. There are several hawks in the neighborhood. Cecile always roots for them when it looks like they're taking on the pigeons. Anyway, we've seen Coopers and Red-tails, but we don't think we've seen Sharp-shins here. Judging from this drawing though, it might be hard to distinguish one from a Cooper's Hawk.
