What other names and breeds do wild geese have? An analysis of why they fly south

The wild goose is a second-class protected animal in China, a large migratory bird with nine breeds, seven of which are found in China. Wild geese usually gather in groups of six or multiples of six, so when we usually see wild geese flying, they are always in flocks, sometimes forming a V shape, sometimes forming a straight line. Let us take a look below at what the wild goose's alias is, which breeds there are, and why it flies south.

1. What is the wild goose's alias?

The wild goose's alias is wild goose, and it is a mangrove wildlife species of the subfamily Anserinae, a general term for birds of the genus Anser. Their common characteristics are a relatively large body size, a very long beak, prominent upper mandible teeth, and a streamlined body.

2. Which breeds of wild geese are there?

Common wild goose breeds include the swan goose, bean goose, bar-headed goose, greater white-fronted goose, and greylag goose.

1. Greater white-fronted goose

The greater white-fronted goose mainly breeds in the tundra permafrost zone of the Northern Hemisphere; it generally migrates to temperate farmland to overwinter.

2. Greylag goose

The greylag goose is mainly found in northern Eurasia, and overwinters in North Africa, India, China, and Southeast Asia.

3. Brent goose

The brent goose mainly breeds in the tundra permafrost zone of North America and polar Siberia; it overwinters on southern coastal grasslands and estuaries.

4. Swan goose

The swan goose is mainly distributed across Eurasia and northern Africa, including all of Europe, the African region north of the Tropic of Cancer, the Arabian Peninsula, and the Asian region north of the Himalayas-Hengduan Mountains-Minshan Mountains-Qinling Mountains-Huaihe River line.

It breeds in Mongolia, Northeast China, and Siberia, and overwinters in the warm zones of central and eastern China and Taiwan, China, as well as Korea.

3. Why do wild geese fly south?

Wild geese flying south is a relatively common phenomenon. When autumn turns cool, we see flocks of wild geese flying south in the sky. Why is this?

Wild geese fly south mainly to find a warm habitat and search for food, so they can successfully get through the winter. Everyone knows that the wild goose is a migratory bird whose original home is in the Siberian region of the north. When winter comes, that place is all ice and snow, with no food, not even tiny insects or plant seeds, so wild geese find it very hard to find food and fly south in flocks.

When wild geese migrate, we see their regular dynamics: experienced old geese lead at the front, leading the flock, while the ones behind line up in a row or form a V shape, constantly calling out, which serves to encourage the flock.

Because the route wild geese take south is relatively long, besides relying on their powerful large wings, they also need to use rising air currents so that their wings can get time to rest and save energy.

Generally, wild geese need one to two months of flying south to reach a place with food and warmth and successfully overwinter. When spring comes, they fly back north to lay eggs and reproduce.
