How do animals use directions to  nd their way?

           Animals like whales move north each year, from Mexico to the waters of

           Alaska, to feed on lots of  sh. Then the whales move south, back to Mexico,

           so baby whales can grow in warm waters. Butter ies often move from

           north to south and back again for food. Many kinds of birds travel from the

           east to the west every year. Over one million animals in Africa move north

           and south, east and west in the Great Migration.






           Can we  nd directions without a compass or GPS?

           Before the existence of the compass or GPS, people

           used to  nd their direction at daytime guided by the

           sun and the shadows of objects on the ground. At

           nighttime, people knew their direction by spotting

           the North Star in the sky. These methods are still

           used till today.
