What season is it when geese fly south?

It's autumn when geese fly south. The climate in the north is warm, and the seasons are like spring. Birds live a happy life there. But about 3 million years ago, the earth suddenly became cold, and it was in the Quaternary Glacier period. It was freezing in the north, and birds had difficulty finding food, so they had to leave their hometown and fly to the warm south for the winter. Later, when the glaciers thawed and the weather became warmer, they returned to their hometown to have children. It has been formed for a long time that it must fly back to the north every spring and fly to the south in autumn.
