Danger!
Here is a head shot of a red shouldered hawk (Buteo lineatus) that is hanging around lately. Though, the bird hasn't come back to my yard, I've caught glimpses of the hawk swooping through the trees. Notice the sharpness of the beak.
"Although the American Crow often mobs the Red-shouldered Hawk, sometimes the relationship is not so one-sided. They may chase each other and try to steal food from each other. They may also both attack a Great Horned Owl and join forces to chase the owl out of the hawk's territory." - allaboutbirds.org
