What is Causes of Bird Migration Explained about?

Bird migration is caused by changes in weather patterns and food availability. As winter approaches in northern regions, food becomes scarce and temperatures drop, making survival difficult. Birds migrate south where there is more food and warmer conditions. Their migration is triggered by changes in hormone levels which prepare the birds physically for long flights to more hospitable locations with resources needed to live.
