When ducks swim in formation, what do they rely on to change directions neatly?

The duck changes direction based on vision. Male ducks molt their feathers twice a year. The eggshell is smooth; the legs of both sexes are covered with overlapping scales. All ducks reach sexual maturity in their first year and are paired only during the breeding season. The duck formed an inverted fan shape in front of the boat and pushed forward with force. At the same time, they create a fan-shaped current. Each duck has its own little fan of water separated by its own body.

The pattern they weave appears to be very regular in large fans of water. Whether it is a small fan current or a large fan current, it is very urgent and powerful. Ducks don't care, as long as they have water, water will always be their home. They started looking for food. After searching for food, I suddenly became interested and shouted several times to the sky. Ducks are very smart. Also on the water at night, they suddenly felt like homeless wanderers.

They surrounded their master's ship, lest they be separated from the only ship from which they felt they could still have support. They put their beaks on their wings as if they would never worry their owners about sleeping. Sometimes they would stick their heads out of their wings to have a look at the owner of the ship. Ducks are different from swans and geese in that they have the following characteristics: ducks are small in size, have short feathers, and have limited flight distance. All ducks mature sexually in their first year and mate only during the breeding season, unlike swans and geese, which mature later and mate for life.

Based on their unique behaviors, ducks can be divided into three major categories: dabbling ducks, diving ducks and perching ducks. The mallard is a typical teal duck and the ancestor of most domestic ducks. Ducks like the Moscow duck have long claws and are the most arboreal of the ducks. There are the most species of diving ducks (including sea ducks). Mallards fly from the south to the north in spring to lay eggs, and then fly south again in autumn to spend the winter. After being domesticated by humans, they lost the opportunity to migrate. Ducks can see 360 ??degrees with their eyes and see behind them without turning their heads.
