Why do geese fly south?

Wild geese are one of the well-known migratory birds. When migrating, dozens, hundreds, or even thousands of them always gather together and fly in line with each other. The ancients called them "wild geese". But do you know why the geese fly south? Let's take a look at it together.

Why do geese fly south?

Geese fly to the south to spend the winter, the south has a tropical climate, it is warmer than the north, the food will be more abundant than the north, geese belong to migratory birds, flying south is to overwinter. Migratory birds are generally birds with migratory habits and regularly come and go between overwintering places and breeding grounds with seasonal changes, with large groups, regular time and place, and fixed overwintering places, breeding grounds and migration sites.

Wild geese are birds with strong flying ability.

Wild geese are excellent air travelers. Every autumn and winter, they fly in groups from their hometown of Siberia to the south of our country to spend the winter. The following spring, after a long journey, they returned to Siberia to lay eggs and breed. Geese fly very fast, can fly 68,90km per hour, thousands of kilometers of long journey has to fly for a month or two.

During long-distance trips, the ranks of geese are very closely organized. they are often arranged in a herringbone or a zigzag shape. as they fly, they keep making "quack, quack" sound. The call of the geese serves as a signal to take care of each other, call, take off and stop.

Why are the geese lined up in the word "one" or "man"?

Wild geese fly in the shape of "man" or "one" because they fly all day, and it is not enough to rely on the strength of one goose alone. They must help each other in order to fly fast and far. When the energetic geese flapped their wings and flew, a gust of wind rose from the tip of their wings and sent them from below to the top, then they lifted the geese gently, and the geese who traveled a long distance would not be left behind.

Generally speaking, the geese in front are very powerful and experienced. Due to the role of the head geese flapping their wings to drive the airflow, if the geese fly in the shape of "human" or "one", the geese behind will fly very easily and do not have to rest many times. In the process of flying, the geese will form a low-pressure area behind them, which can be used to reduce air resistance when the geese are flying. It is beneficial to the continuous flying ability of the whole group.

In addition, the arrangement of geese in a neat herringbone or zigzag shape is also a manifestation of group instinct. Because it helps to defend against enemy attacks. The geese always have experienced geese as the "captain", flying in front of the team. During the flight, the leading goose exerts a lot of physical strength, so it often changes places with other geese. Young birds and frail birds are mostly in the middle of the line. When stopping by the water to look for water plants, an experienced wild goose always acts as a sentry. If the lone geese fly south, they are in danger of being eaten by the enemy.
