The migration of migratory birds is closely related to climate change. Migratory birds are very sensitive to climate change. Once the climate changes, they begin to migrate. This can avoid the cold in winter in the north and the heat in summer in the south.

Climate change also directly affects the food conditions of birds. For example, after autumn, most plants in northern China withered their leaves, and insect activities decreased. After laying eggs, they successively burrowed into the ground to sting or die, and the number dropped sharply. The lack of food makes it impossible for birds that eat insects to sustain their lives. Only by migrating to the food-rich south can they survive the winter well, and insect-eating birds and small insect-eating birds also move south.

Weather, wind direction and wind force have great influence on bird migration. It is more suitable for sunny days with downwind of 3-5 winds. According to the data, the annual average temperature in Inner Mongolia (1981-2010) in spring is 6.6℃, and the average precipitation is 31mm. There are many sunny days and few rainy days, and there are 4 or 5 northwest winds. Climate conditions are more suitable for migratory birds, so Inner Mongolia has also become the most important transit station and post station for migratory birds in China.
