Goose and swan not only differ by one word in name, but also have some similarities in appearance and living environment, so it is easy for many people to confuse them. Some people even think that "domestic goose" is a domestic swan, and "domestic goose" is bred after artificial domestication of wild swans. So, are domestic geese and swans close relatives?
First of all, in terms of appearance, domestic geese are generally smaller than swans, with short and thick necks and short and round tails; domestic geese have a variety of body colors, including white and grey geese; and feet are orange-red, while the swan's beak is black, yellow and orange, and its legs and feet are black.
The foreheads of domestic geese have fleshy tumor-like protrusions, especially in males, except for mute swans, which do not have sarcomas. In addition to the above-mentioned differences in appearance, the neck of the swan is slender and curved. When feeding, it usually reaches into the water while its torso remains afloat and generally does not dive. However, domestic geese have thick and straight necks. When feeding, its head, neck and front of torso dive below the surface, while its tail, legs and feet are above the surface.
Swans swim with slow movements and graceful postures, especially during courtship, the male and female often kiss each other with their beaks or head and neck, which is very beautiful. Relatively speaking, the swimming posture of domestic geese is laborious and clumsy. When swimming, he stretches his feet back and strokes the water hard, just like a stroke. In the poem "Yong Goose", Luo Binwang has an image to describe "white hair washes green water, red palm rattles the waves".
Second, in terms of living habits, after artificial domestication and selection, domestic geese have enhanced cold resistance and stronger resistance to roughage, but their wings have degenerated and their flight ability has weakened. migration.Wild swans usually migrate long distances in the fall and winter, flying at high altitudes, they form "ones" or "humans" and fly together in groups to the warm southern wintering grounds in search of food, and then in spring and summer Return to the northern breeding grounds.
To its credit, the domestic goose has maintained a habit of vigilance and vigilance despite having been domesticated by humans for over 5,000 years. When encountering strangers or other natural enemies, livestock and poultry (651, 194) in their own territory, especially near their nests, eggs or goslings, the goslings will immediately "croak" to call the police, spread their wings, and make a Flapping and pecking gestures until the opponent retreats and leaves, so some areas also use it as a watchman.
Finally, from the point of view of origin and evolution, domestic geese are artificially domesticated by wild geese (Chinese domestic geese originated from swan geese, except for Yili geese, European geese and Yili geese, most of which originated from gray geese and are flat geese. genus, ranunculus and geese, while swans are birds of the genus Ranunculaceae, ranunculus and swans. There are 8 species in the world, such as whooper swan, cygnet swan, mute swan, black swan and black-necked swan. Among them, whooper swans, little swan swans and mute swans are distributed in wild populations in China, and they all belong to the second-class national protected animals (except commercial swans that have been approved for special breeding by law). Therefore, domestic geese are not domestic swans, nor artificial swans. It is bred after domestication of wild swans.
The domestic goose and the swan are not the same guy or close relative. Relatively speaking, the genetic relationship between the domestic goose and the geese (goose, geese, etc.) is closer.
What is the difference between geese and geese ?
Goose is a kind of bird that can fly. In autumn and winter every year, we often see rows of geese flying south. Geese are animals that have only been known in recent years.

The geese is a collective name for various goose subfamily and is a large bird. Shaped a bit like a domestic goose, some are smaller. The muzzle is broad and thick, with broad mouthparts and a blunt comb-like protrusion on the undercut. The plumage of males and females is similar in color and is mostly striped taupe. Great flocks of geese live near the water, usually in flocks. When staying at night, there are geese watching around. If there is an attack, they will call the police. The staple food is young leaves, fine roots and seeds, occasionally pecking at the grains of the farmland. Every year after the vernal equinox, they fly back to the north to breed, and after the autumnal equinox, they fly to the south for winter. Wild geese fly in the shape of a "one" or "man", which is called "wild geese". Because the team is neat, people call it "Strict Formation". The flight path of geese is straight.
Red goose, bean goose and white goose are common in China. Geese, there are 6 or multiples of 6. A flock of geese is a family, or a collection of families.
What is a geese?
The Landes goose, native to the Landes department in southern France, is the best goose in the world for producing foie gras. Because its plumage is predominantly grey, it is sometimes called the grey goose. As for the introduction of geese in China, some people call them big geese, which may be because of the need to sell seeds. In fact, it has nothing to do with geese, let alone "rare animals". Regardless of the production of foie gras, its meat quality and nutrition are not much different from local geese.
The difference between goose and goose
1. The goose's mouth is fleshy red (if its mouth is citric red, it is a Lande goose), and its neck is long and not thick, making it easy to fly.
2. The body of the goose is very small, and the tail of the goose is not raised or pressed down. This is the result of the long-term flight of the goose.
3. Geese without drooping rump were collected and geese with drooping rump were collected in round geese.
4. Wild geese have streamlined bodies, like birds. If they are like geese, they are round geese.
5. Wild geese can lay 20 eggs per year, and Lande geese can lay more than 50 eggs per year.
6. Wild geese can fly, and the maximum weight is about 8 kg. Round geese are flightless and weigh more than 10 kg.
