WHY DO BIRDS MIGRATE? • Bird migration is the regular seasonal journey undertaken by many species of birds. • Bird movements include those made in response to changes in food availability, habitat or weather. • Approximately 1800 of the world's 10,000 bird species are long-distance migrants.
ARCTIC TERN • The Arctic Tern is a sea bird. • The species is strongly migratory, seeing two summers each year as it migrates from the north along a winding route to the oceans around Antarctica and back, a round trip of about 70,900 km each year. • This is by far the longest regular migration by any known animal.
BAR-TAILED GODWIT • The Bar-tailed Godwit is a large wader, from the Arctic coasts and Tundra and winters on coasts in temperate and tropical regions. • It makes the longest known non-stop flight of any birdwithout pausing to feed by any animal, 11,680 km along a route from Alaska to New Zealand.
