Cooper's Hawk at the San Luis National Wildlife Refuge

We were fighting the crowds at a couple of shopping centers in Turlock, saw that the sun was sinking in the west, and just simply decided we wanted some peace and quiet. The San Luis National Wildlife Refuge was just 15 or so miles to the south (specifically the Bear Creek Unit). We headed out of town and drove to the auto-tour and slowly crept along the road. The pools were all dried up so no migratory birds were present in that part of the refuge, but we did see a Cooper's Hawk (Accipiter cooperii) perched in the trees along the east edge of the trail. The Cooper's is similar in appearance to the Sharp-shinned Hawk, but the tail was distinctive enough that I went with the former as an ID.

Those red eyes are intense!
