Birds fun facts. Flying tirelessly for 11 days.

There are many bird species that make large migratory journeys. These trips are meant to fulfill the need to feed and are usually carried out in a south-north direction and vice versa. Sometimes, they travel along many, many miles. They tend to do this in stages, i.e. they stop for a few days to rest, feed, gather strength and go back to their flight.

The species that makes the longest migration is the arctic tern, which breeds in the Arctic during the northern summer and then moves to warmer lands near the Antarctic ice. It travels a distance of between 20,000 and 38,000 kilometers on each journey, depending on the chosen route. They make the journey by flying over the sea, until they reach their destination.
