I spotted this great blue heron standing guard near a drainage fence and pipe at the celery fields. He was very intent on staring at the water, although it didn't seem like the best place for a fishing expedition. A couple of times, he wandered a few yards away, only to return several minutes later and resume staring at the water once again. Perhaps he was aware of something I wasn't. While observing this somewhat agonizing process, I just kept thinking, 'I'm glad I don't have to hunt for my dinner tonight.'
