Migration is the seasonal movement of birds at regular intervals of the year to overcome adverse effects of the changing climate. Birds migrate in search of warmer places for egg laying, better shelters and to escape unfavourable conditions. e.g. A number of birds migrate to the Vedanthangal Bird Sanctuary. In other words, when natural habitats are not conducive for breeding, birds move to safer areas to breed, which is called migration. Birds that fly from far-off places to reach a new habitat are known as migratory birds.
