What animal is a goose?

Goose is improved from grey goose and swan goose to make use of their meat, eggs and feathers. The former was raised as poultry by the Greeks in 2000 BC, and many varieties were cultivated with Europe as the center; The latter system, also called China Goose, was transported to Europe from China in the18th century and was also improved.

As mentioned upstairs, both grey geese and red geese belong to an order of birds, Anatidae. The feathers of this genus are dark brown to black, and the male and female feathers are the same color (ducks have different colors). It is said that husband and wife will stay together for life until one of them dies.

The second long feather of the family Anatidae is shiny. During the breeding period, feathers will fall off because of metabolism. Except for tropical species, most of them migrate. Usually, they fly to swamps or rice fields at sunset and feed on fresh water-producing organisms at night. They usually live in groups except during the breeding season. Be cautious by nature. During the breeding period, the male bird has a strong sense of defense and will delimit the sphere of influence; The female bird is responsible for nesting and hatching eggs. Nests are mostly made of leaves and stems of plants and covered with feathers. There are 46 species in China.

Swallow-shaped beaks are wide, short and flat, and the edges are toothed. The fat glands in the tail are developed, which can moisten feathers and prevent water. 4 toes, of which 3 toes are forward and webbed (except for a few species). As a waterfowl, he is good at flying and drowning. Usually, the wings vibrate and fly, and they glide when they touch water. Distributed in the northern hemisphere.

The grey goose is 70~85 cm long. Feathers are mostly gray, and the beak and feet are orange-red. This is quite common in Europe. Form a group as a family. When eating, there will be guards to observe the surrounding movements. When migrating, it is to integrate the operations of large groups. When flying long distances, a V-shape will be formed. Female birds usually lay 4-6 eggs at a time. Only the female birds hatch eggs, and the female birds will bring back the eggs that have fallen into the nest with their beaks. It takes about 28 days to hatch young birds. The chicks can swim with their parents the next day after hatching. The newly hatched chicks will regard the things around them as their parents, so they often regard their owners as their parents and walk together.
