I was happy when this individual perch on a nice branch and with clean surroundings - these guys like messy habitats! It was perched facing me for the longest while, and I got many good pictures of that, but when it turned around and started to preen it was even better IMO. Out of many images of the preening session this was my favorite in part due to the ruffled feathers and perfectly curved plume.
Canon 7D + 500mm f/4 II + 1.4 TC, manual exposure, evaluative metering, 1/1000s., f/5.6, ISO 800, natural light, handheld, small crop for comp, the worst offending specks in the water removed, darkened the legs as they were almost washed out in-camera.
