I was out on my daily tour, looking for great spots to photograph. Actually, I was on my way home. After a good half hour spent tracking a duck, and feeling pretty satisfied with the results, it was time to get some dinner. And that's when I spotted the heron. Driving past a marsh at about 45 mph, the bird caught my attention out the corner of my eye. And there was nowhere to pull off. A quarter mile up the road I found a spot and started hiking back, sure the big bird would have moved on by now.
He (she?) had not. But it was a bit deeper in the marsh, making it harder to get the shot. And along the way, I got this great shot as well.
