This guy took off by surprise, but I was able to track it and take a few images of it speeding along the water. It never really took off to the air, but rather settled right back in...closer to a female it was eyeing.
Canon 7D + 500mm f/4 II + 14.TC, manual exposure, evaluative metering, 1/800s., f/6.3, ISO 800, natural light, handheld, slight image rotation and then cropped for composition, darkened some brighter elements along the BG shoreline (burn and clone tools). NR to BG (may go back and do some to the blurred wings)
