How migratory birds get their way from one location to another?
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.This has been proved by letting birds fly in a planetarium and changing the stars' position. Another tool is the earth's magnetic field (earth's north and south magnetic poles). Some birds, like pigeons, have a small zone in their brain made of magnetite (magnetic mineral), just like a small compass.
