MIGRATORY BIRDS

When winter comes, a lot of birds migrate to Africa and other southern countries

Page 4: Bef1afa2 migratory birds

Why do birds migrate?

Because there isn’t much food in winter, they go to warm countries to find food.

In spring, they return home, where they mate, they lay eggs in the nests and rear their baby birds.

How long is their journey? Birds fly for a lot of days because

they must travel across tens, hundreds, even thousands of kilometers in difficult conditions.

Page 6: Bef1afa2 migratory birds

Some birds fly 30-35 km a day. Others fly non-stop, day and night; they eat while they are flying and they sleep in the air. Some birds must travel 2,000-3,000 km without a break.

 

The arctic tern is the animal that travels the most during migration. Some arctic terns travel 90,000 klm from the North to the Antarctic. In this way, they have two summers every year!

Dangers

There are a lot of dangers for migratory birds, like:

bad weather

hungry predators (e.g. birds of prey, foxes etc).

Page 8: Bef1afa2 migratory birds

Dangers

Also, birds die when they are too tired or

when they can’t find enough food.

People kill thousands of migratory birds, too.

Page 9: Bef1afa2 migratory birds

Dangers

Tall blocks of flats, roads, wind turbines, TV aerials, cables can kill birds when they are in the wrong place.

Dangers

And sometimes the places where they eat are smaller now and their journey is bigger. For example, the weather in Africa is different now and the Sahara desert is bigger.

Page 11: Bef1afa2 migratory birds

So the birds can’t find water and food because there is drought and there aren’t many places with food and water. They travel more to find food and many die.

Dangers

And, finally, pollution.
