I photographed this heron last month about 1/2 hour before sunset. Being a juvenile, he let me creep up relatively close to him. I took my time, and he certainly didn't seem in a hurry.
Luckily I was paying attention to my background, and as a result, made a correction in the field. My tripod legs were lower than normal, as I had been photographing snowys at water level. This guy was perched atop a short fence, so my lens angled up slightly, giving me a sliver of sky above the green bank behind him. I readjusted the height of my rig, and saved myself a lot of photoshop work!
