$\huge\underline\mathfrak\red{Migration\:}$

$\star$ Migration is the periodic movement,of a species of animals or birds,from the place where it has been living,to a new area and it's subsequent return journey back to the original home. When animals and the birds migrate,it is usually to find abundant food and a favourable place to breed.

$\star$ The practices method,by which animals navigate and know where to go,are still obscure. Birds have much sharper eyesight and better visual memory of ground clues then humans. However, in long-distance flights,they appear to navigate with the help of the Sun and stars,Possibly in combination with a reading of the Earth's magnetic field. This is achieved through an inbuilt magnetic compass which is a tiny mass of tissue,between the eye and the brain, in birds.
