Ducks and geese fly close to the water to remain in ground effect, an aerodynamic condition that occurs while flying less than one wingspan above a fixed surface. Flying in ground effect takes advantage of increased lift and decreased aerodynamic drag that wings generate when they are close to a fixed surface.
Why do birds fly close to the ocean?
As the bird nears the water surface, the ground effect becomes stronger. It is also more efficient over calm (flat) water. This aerodynamic phenomenon is very important to aerial wildlife, and it has been copied by humans. During World War II, long-range bombers often flew close to the water’s surface to conserve fuel.
Why do ducks flap their wings in the water?
Ducks flap their wings for a couple of different reasons. They will flap their wings during mating season to attract females and warn other males to stay away.

How long can a duck fly without stopping?
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.
What do ducks do all day?
Waterfowl spend many hours a day loafing, sleeping, and performing basic maintenance and comfort movements like preening and stretching. The birds select loafing and roosting sites based on the temperature, humidity, wind speed, and sky conditions.
Where do ducks sleep?

They are flexible when it comes to their choice of where to sleep. For example, a species of ducks known as mallards can sleep both on land and water. Another species known as Muscovy ducks can also roost (sleep) on the ground.
