What is the reason why a large number of toads moved collectively in Lianjiang, Fujian recently?

The person in charge of Lianjiang Meteorological Bureau said that it is normal for a large number of toads to appear in rural areas. These little toads are young frogs that have just evolved from tadpoles. Because toads are amphibians, their habitat will change from the original water environment to the land environment after evolution. The emergence of such a large number of collective migration of toads is closely related to the recent climate change. Recently, the weather is getting warmer, there are more thunderstorms, the weather is sultry, the air pressure is reduced, there will be lack of oxygen in the water, and there will be many mosquitoes at low altitude, so toads will move collectively and come out for food.
