A Cooper's Hawk was perched on a branch in the backyard this morning. Kim gets the credit for spotting it and calling me over. I only had time to take a few pictures before it flew off. Not exactly a rare bird but beautiful regardless. It seems it can be difficult to identify a Cooper's Hawk vs. a Sharp-shinned Hawk, but this site was helpful.
