Swans can fly. Because the swan refers to the swan genus (scientific name: cygnus), there are 7 species of birds, the swan is a winter migratory bird, like to live in groups in lakes and swamps, mainly feed on aquatic plants.
Every year in March and April, they fly in large groups from the south to the north to lay eggs and breed in the northern border provinces of China. As soon as October passes, they move south in groups. Wintering in warmer climates in the south and recuperating. During the breeding period, it mainly inhabits open lakes and ponds
Morphological characteristics of swans
Swan feathers are all white, and both females and males are white, but females are smaller. The eyes are dark brown, the mouth is black, the upper part of the mouth is yellow, it extends to the nostrils, and forms a trumpet, the claws are all black, and in childhood, the whole body is grayish-brown.
The swan's beak is very sensitive to the touch, known as Hebber, the body weight can reach 10,000 kilograms, the length of the wings can reach 641 mm, the length of the tail can reach 210 mm, and the length of the feet can reach 120 mm.

Domestic geese can fly. The ability of geese to fly may be an acquired ability. The domestic goose originated from the wild goose, although the wild goose has been domesticated by humans for a long time, the ability to fly has deteriorated, and it has become a goose, but the flying gene still exists.
Under the right conditions, there is a good chance that this ability will recover. Again, the goose raised in the north is generally a seed goose, and the female goose is generally about two kilograms, and the body is relatively agile and suitable for flying, if it is a lion-headed goose in the south, the heaviest can reach 10 kilograms, and it is estimated that it is difficult to fly no matter how hard it is.
As a waterfowl, geese like water by nature, 1 3 times a day are in the water, accustomed to frolicking, foraging and courtship in the water, so the goose farm should be established in the environment of good water sources and wide waters, especially in flowing waters such as ditches, lakes and rivers.

Domestic geese are domesticated by swans, and in the process of domestication, people choose to breed those with large size, more meat and poor flight ability. In short, the geese are too heavy to fly. But in fact, the geese can fly even if they flutter twice, but they don't have to be high or far.
-
The former is wild and retains the ability to fly and the habit of migration. The latter is bred in captivity. Without flying, the ability to fly is lost through generations.
-
Because their genes are different, swans fly while geese don't.

Swans are the tallest birds to fly in the world!
The domestic goose is the offspring of a species of wild goose that has been domesticated; The ability to fly high has been lost!
In the past, in some zoos, in order to allow swans to escape, they would cut off the swan's flight feathers, resulting in swans swimming in the zoo's pool!

The goose, considered to be the first domestic bird domesticated by humans, comes from the wild wild wild wild goose or grey goose. The Chinese goose comes from the Hung Goose, while the European goose comes from the Grey Goose.
Geese are a species of ducks of the order Ornithischia. Ducks are complex, and the geese, swans, ducks, and mandarin ducks we often say are all ducks. Some of these animals were domesticated into domestic birds by humans, such as the mallard duck into the domestic duck, the Hong goose into the Chinese goose, the gray goose into the European domestic goose, and the mute-nosed duck into the Muscovy duck.
These members have a variety of appearances and habits: some eat plants, others fish; Some can only float on the surface, while others are good at diving; Some are among the most capable birds, while others are not good at flying. There are several species of swans such as mute swans and whooper swans that are the largest migratory birds and among the largest flying birds.
Mute swans are also the most elegant birds, which are commonly found in parks in Europe, but less so in our country.
The ancestor of the domestic goose is the goose, which was domesticated by humans about three to four thousand years ago. It is now bred all over the world. The goose head is large, the beak is flattened, and there is a sarcoma on the forehead.
The neck is long, the body is broad, the keel is long, the chest is full, the tail is short, and the feet are large and webbed. Grass-eating, cold-tolerant, gregarious and disease resistant. It grows fast and has a longer lifespan than other poultry.
Weight 4 to 15 kg. Ovidulum period for one month. Inhabits near ponds and other bodies of water.
Good swimmer. The main species are lion-headed goose, Taihu goose and so on.

You have a logical error, geese are also birds, but they have been domesticated due to genetic reasons, there are a few geese that can fly low (except for geese, which are mostly flying).

Swans have wings and fly feathers. The length of the first primary feather is about half the length of the second feather and almost the length of the third feather, and it is the longest of the feathers. tail short and slightly rounded, tail feathers 20 24, tarsoplantar short and stout, located at the back of the body, tarsoplantar anterior margin covered with net scales; The toes are strong.
The hind toes have a muzzle. Both sexes are of the same color, or the female is slightly lighter (e.g., a black swan). Young birds are mostly brown.
The swan is a winter migratory bird that prefers to live in groups in lakes and marshes, feeding mainly on aquatic plants.
The Swan is a champion flyer, flying up to 9 kilometers and flying over the world's highest mountain, Mount Everest.

Swans are migratory birds and have to complete their migration by flying.

Don't fly swans don't feel like vases??
I miss you so much. The swan flies away, and the bird does not return, because the bird has flown away, and only my word remains. The good word headless double is very good, the word headless is to remove the point on the head of the good word, and the double match is the overlap of the two people and the good word headless to become a very word. >>>More
The little budgie is definitely easy to raise.
As far as birds are concerned, we all know that their claws are not ordinary claws, they are very powerful. As long as you are a friend who lives in the countryside, you can observe it yourself. For example, a bird can stand on a power line and not fall off, which we humans can't do, so the function of a bird's claws is unusual. >>>More
The yellow-billed rhododendron, which breeds in North America, is nested by husband and wife. Since females lay 10 eggs per breeding period, the interval between eggs is so long that it often leaves chicks and newborn eggs mixed in the same nest. Feeding the chicks leaves the female no longer in mind the incubation of the eggs, but she has to finish laying the eggs. >>>More
