Based on the morphology of the wash-out, it is VERY close to the outline of a sharp-shinned hawk or Cooper's Hawk. Note the tail feathers very close together (not fanned out like a red-tailed haw). The high aspect ratio of the wing indicates a fast flyer that is capable of catching prey in the air, as opposed to a low aspect ratio like an owl, whose wings are designed more for silent, stable, balanced flight. So this narrows it down to Accipiters (falcons, some hawks). The whole profile is too slim to be a red-shouldered hawk, and they prefer frog-sized food anyway.
It's also not a nighthawk, whipperwhill, chuck will's widow, or a common poorwill, because the angle of the wing is not sharp enough. Also, they don't hold their wings in a locked position (like in a dive) so close to their body. Their wings are almost always out away from their body.
I'm puzzled by the barred feathers hanging down in the corner, but it's most likely it's a second individual of the same species. A prey species would not have stayed in the exact same position (with a possible wing drooping down, i.e. relaxed) with a hawk flying around.
So, I say 2 Coopers Hawks or 2 Sharp-shinned hawks.
