Ducks are small in size, short in feathers and limited in flight distance. All ducks are sexually mature in the first year, and they are paired in the breeding season, unlike swans and geese, which mature late and pair for life. According to the unique behavior of ducks, ducks can be divided into three categories: drilling ducks, diving ducks and perching ducks.

The mallard duck is a typical duck and the ancestor of most domestic ducks. Habitat ducks, such as Moscow ducks, have long claws and are favorite arboreal ducks. There are the most kinds of diving ducks (including the ocean).

The mallard flies from the south to the north to lay eggs in spring, and then flies to the south for winter in autumn. After they were domesticated by humans, they lost their frivolous migration. Duck's eyes have a 360-degree field of vision, and you can see behind you without turning your head.

Floating reason

Duck's tail has a large fat gland called caudate fat gland. Its chest can also secrete a kind of "powder" keratin tablets containing fat. Usually, I often peck with my mouth, rubbing the fat secreted by the fat glands at the tail and the "powdery" horny flakes secreted by chest hair on the feathers;

Therefore, when it enters the water, its feathers will not touch the water. At the same time, its feathers are very light and can be lifted by water and float on the water. Besides, geese and waterfowl are just like ducks. Although chickens also have fat, the amount is very small, so they can't float in the water.
