Cooper's Hawk
I had stopped at Douglas Town Hall and was just getting back in the car, when this hawk flew across my line of sight with a Blue Jay close behind it. It landed briefly just beyond the town hall, and I was only able to get a long-distance shot before it flew off again.
Red-Tailed Hawk
I stopped at Hopkinton State Park and looked for drifting snow to photograph. There wasn't much of a selection. I saw better when I was out driving about earlier, but most times, there was no safe place to stop.
