Birds are certainly the most known representatives of migratory species and fascinating in their incredible flight strategies. They attract millions of birdwatchers and eco-tourists all over the world. Approximately 1,800 of the world's 10,000 bird species are long-distance migrants. The shorebird species raise millions of chicks in the Arctic tundra each year, making use of the short, lush summer season when there is an abundance of insects. Among these specialist Shorebird species is the Bar-tailed Godwit (Limosa lapponica), which makes the longest known non-stop flight of any bird and also the longest journey by any animal, without pausing to feed - 11,680 kilometers between Alaska and New Zealand.
