There are many reasons for animal migration, but the main reasons can be summarized as follows:
1. Looking for food and water sources: Animals need to obtain enough food and water sources in order to survive. When resources in an area decrease or drought occurs, animals will migrate to other areas to obtain better living conditions.
2. Climate change: Climate change is also one of the important reasons driving animal migration. For example, during cold winters, some animals migrate south or to lower altitudes to avoid the cold weather.
3. Breeding needs: Some animals breed in specific seasons, and they migrate in order to find an environment more suitable for breeding.
4. Avoid predation: Some animals will migrate on a large scale to avoid being hunted by natural enemies. For example, wildebeest on the African grasslands will gather in large groups to increase their own safety when facing natural enemies such as cheetahs.
In short, the reasons for animal migration are complex and diverse, involving multiple factors such as survival, reproduction, climate, and natural enemies.
