Test of Migratory Bird Behaviour
Migration by birds is a special behaviour of birds. The climate of the place where birds migrate is suitable for them and they also get sufficient food. According to biologists, birds usually migrate to those places where some offspring of their ancestors, that is, some of their relatives, is present. Migratory birds migrate from 5 km to thousands of km. Before setting out on this long and difficult migration, birds eat a lot of food.
