When migratory birds have to travel from north to south or vice versa, they align themselves with the magnetic field lines and travel to their location. • Along with this, migratory birds may also find their way by creating a mental map of their route using mountains, rivers, etc. Besides this, it is also believed that migratory birds use the location of the sun and stars to find their way and reach the same location.
