Why do they Migrate?
Animals do many different and amazing things. Some of them ‘migrate’. This means they travel to other places where the weather is warmer or they can find more food.
For example, sometimes when the weather is very cold the ground surface freezes and it is too hard for birds to pull worms from the soil so they have to look elsewhere for food.
These trips can be dangerous. Some birds travel in large flocks. Can you find out which groups of birds fly in flocks?
Migration may be part of a yearly cycle of changes a bird goes through.
How do they know when it is time to leave for the winter?
Birds can fly very long distances but some birds migrate shorter distances.
How do they find their way to the same place each year?
There are a few mammals, like some bats, caribou, elk and whales that travel in search of food each winter.
Many fish migrate. Where do the fish swim to?
Insects also migrate. Some butterflies and moths fly very long distances. Most migrating insects go much shorter distances. Many, like termites and beetles, move downward into the soil. Earthworms also move down, some as far as six feet below the surface.Read More: Credits
