Great catch...both you and hawk.
Looks like a younger crow to me. I've seen grackles and robins and I would say this is a crow.
A few years ago I was in a riverine forest area near my house and there was a family of Great Horned Owls. A parent was hunting, probably for rabbits or squirrels and the two young owls were watching the parent with great interest,bobbing their heads up and down, staring intently, no doubt picking up hunting tips.
I looked up the diet of the Great Horned Owl and it reminded me of the list of prey for the Tasmanian Devil in the old Loony Tune cartoon...which was a list of about everything you could think of.
