Great blue heron

I got to take my lunch break today at Golden Gate Park. Walking around a lake, I was surprised to find this great blue heron very close to shore. He was so intent on catching a fish that he didn't notice me photographing him several feet away. After his unsucessful stab at the fish, he noticed me and stood for a few moments, wondering what to do. Meanwhile, another great blue heron attacked him from behind and drove him from the lake. I hope he has better days.
