An American Kestrel.
I really enjoyed photographing this as my wife, who is notoriously scared of birds, came out on a trip with me. She had binoculars and I had the camera. She got so excited to spot this one that she overcame her fear of birds, albeit temporarily!!! Oct 25th 2020. Consumnes River Preserve, CA.
