Work and being out of town has gotten in the way of SF birding so it was good to be back and checked out Heron's Head. The White-tailed Kite continues, 2 Osprey were visible. Struck out on the Ridgway's Rail but we were treated to the surprise sight of a female American Kestrel mixing it up with a juvie. Cooper's Hawk before both beat a hasty retreat. Quite a size difference between the two!
