Many birds make seasonal
migrations. How far they travel depends on the type of food
they eat. Seed-eating birds just need to avoid the worst of
the weather. Seeds can be found in the winter.
Seed-eating birds may migrate just a short distance.
Insect-eating birds may have to travel south because there may be
nothing to eat in the far north in the winter. They need to
fly hundreds or thousands of kilometers south to ensure a supply
of insect food. They return north for the summer when there
will be plenty of insects.
Some of the distances
covered by birds on migration are huge. Willow warblers can
travel 12,000 km (7,500 mi.) twice a year. The longest
migration route is made by the arctic tern, which travels from the
Arctic to the Antarctic and back. Many other seabirds also
make long trips across the oceans. Most migrating land birds
avoid sea crossings as much as possible. This is why great
congregations of migratory birds can be seen crossing narrow
straits such as between Gibraltar and Africa. A small bird
like a warbler can put on enough fat to double its weight before
migration. It may then have enough fuel to fly for up to
three days without rest.
