Small Coopers Hawk, Sharp-shinned Hawk, or maybe a Merlin? Hanging out where a forested area meets an agricultural field, any of them could be at home here.
The features that CornellLab’s All About Birds uses to distinguish the Merlin from the Sharp-shinned Hawk require flight or at least other angles. The Sharp-shinned Hawk has short, rounded wings and a very long tail. The Merlin has sharply pointed wings, a broad chest, and a medium length tail. Then there are the sex and age variations to confuse the ID.
It may come down to the “bluntness” of the face: the Merlin, a falcon, has a blunt face and the hawks are more pointy.
This fellow stayed put even after I took his photo and had moved on.
