I spotted these two squirrels engaged in combat, although it was probably more play than serious intent. Given all the hawks in our area, I guess the squirrels felt a need to brush up on their self-defense techniques. I photographed this image with a Canon EOS 7D, Canon EF 300mm f/2.8L, Canon 1.4x extender, f/4, 1/1600 second, 400 ISO.
