What season is it when geese fly south?

It is autumn when geese fly south, especially in the Millennium of the twenty-four solar terms.

Usually, they fly to the south for the winter. When flying, geese will fly in a "human" shape or a "one" shape, which is a manifestation of group instinct and is conducive to defending against enemy damage. The time and place of migration are very regular, with fixed wintering sites, breeding sites and migration sites.

Flight characteristics of geese;

The reason why geese fly in herringbone or zigzag is because they fly all day. It is not enough to rely on the strength of a goose. They must help each other to fly fast and far. When powerful geese flap their wings, a gust of wind blows from the tip of their wings, and when they are sent from bottom to top, they are gently lifted up so that they will not fall behind after a long journey.

Generally, the geese in front are very powerful and experienced. Because the head geese flap their wings to drive the airflow, if they fly in a herringbone or zigzag way, the geese behind them will fly easily without taking many breaks.
