Sharp shinned hawk
We had a male sharp shinned hawk buzzing around our feeders. He spotted one bird and they swooped around the yard. He missed nut keep coming back. Based on its hunting skills I think it was a young bird. Shot through a window. Accipiter striatus Female Sharp-shinned Hawks are about a third bigger and heavier than males. This is a typical pattern for many hawks and owls, but otherwise rare in the bird world.
