Hawk, with lunch

I was standing in my driveway, chatting with my tree guy who had just given me an estimate for the periodic trim dead limbs/remove dead trees/tree health stuff. We are still talking trees, so were staring upwards when a large hawk flew by with a squirrel securely grasped in its talons. It flew on to a big pine across the street, landed briefly, and apparently then moved on--we walked over to try to take another look but didn't see it by then.

Joe was pretty sure it was a red-tail--I didn't see the characteristic tail feathers, but then I was surprised enough by just seeing a hawk so close that I wasn't looking for ID marks. It sure was BIG, whatever the species.
