as I have tons of birds on my farm and the only one's I have a real problem with ID are the hawks. They are hard. Beautiful bird.

would be Red Tail Hawk.

Smaller than a red-tailed hawk, larger than a kestrel and lightning fast. Consulted my field guides and online and it’s still a mystery.

Might be a Goshawk

The crows take exception to them and bother the hell out of them.

And the blue jays do the same to the crows.

the in-flight pic the underwing doesn't look like a Cooper's.

The bird is most likely an adult light morph broad-winged hawk.
