This photo shows the size difference between the Accipiters that are commonly
seen during the fall migration at Hawk Hill,
in the Marin Headlands of Northern California. The male Sharp-shinned
Hawk is much smaller than this female Cooper's Hawk. A female Sharp-shinned
Hawk is almost the same size as the male Cooper's Hawk.
You can also see that a Cooper's Hawk will raise its hackles while the Sharp-shinned Hawk's head feathers remain down.
