I was walking by the window & saw a large shape on the brick outside from the corner of my eye. Started hissing hawk, hawk, hawk as I tried to tiptoe to where my camera stays on a tripod by the window. Sometimes the hawk flies before I can get a shot but this time I was more lucky. It is looking towards my shrubs where the little sparrows and juncos hide out when a predator shows up.
Adult Cooper's Hawk (Accipiter cooperii)
