Marsh Facts

Most waterfowl fly at speeds of 40 to 60 mph, with many species averaging roughly 50 mph. With a 50 mph tail wind, migrating mallards are capable of traveling 800 miles during an eight-hour flight. Studies of duck energetics have shown that a mallard would have to feed and rest for three to seven days to replenish the energy expended during this eight-hour journey.

The fastest duck ever recorded was a red-breasted merganser that attained a top airspeed of 100 mph while being pursued by an airplane. This eclipsed the previous speed record held by a canvasback clocked at 72 mph.
