Cooper's Hawk (Accipiter cooperii) Approaching in Rapid Flight
This bird flew low (ca 25 feet or less?) along just west of Road F, from the lonely tree toward me & Escobar Gate. Straight, rapid, purposeful flight. Focusing on the rabbit, staying quiet, I saw something out of the corner of my eye. I pivoted and snapped a couple of images. The auto-focus worked! 1/6400 sec at f/11, ISO 1600.
