Harlequin Ducks are beautiful and dignified and may appear unassuming in their relaxed demeanor. Observe these ducks in action and it becomes apparent that Harlequins are powerful and fearless swimmers. These diminutive beauties are able to negotiate the most violent rapids as they swim, dive, and even walk along the bottom of the river in search of insects and other sources of sustenance. It is a marvel that these birds live, feed, and spend their lives amongst the turbulence and turmoil of raging rivers. Yellowstone River in Yellowstone National Park, Wyoming, May 2016. Canon 5D III, 500mm f/4 IS + 1.4x III, ISO 800, 1/800 second @ f/11, image size 4912 x 3336 pixels.
