John Batchelder photographed this Red-shouldered Hawk, Buteo lineatus, perched on a roof on The Sea Ranch.
You can find this Hawk in California and in the East. They eat small mammals, reptiles, birds, amphibians and crayfish. I bet this Hawk is keeping an eagle eye out (or a hawk eye out) for a nice fat rodent.
Thanks to John for allowing me to share his photo with you here. To see a photo of a seemingly headless Red-shouldered Hawk, here's the link: http://www.mendonomasightings.com/2012/11/10/craig-tooley-says-to-look-out-for-a-headless-hawk-in-the-forest-yes-hes-joking/
