The ruddy duck often dives or swims away from danger rather than flying. When flying, their small wings stroke so fast they resemble bumblebees.
They are early to mid-fall migrants. Drakes often cock their tails upright at an angle, the only species to habitually do so. Both hens and drakes are silent in the fall.
