An Arctic Tern in front of the Monaco glacier in Liefdefjorden, at the northwest tip of Svalbard in the high Arctic.

Every year, the beautiful and tiny 113-gram Arctic Tern makes the longest migration of any animal in the world, traveling between breeding sites in the northern Arctic and survival/moult areas in the Antarctic pack‐ice zone. That practically means flying from the North Pole to the South Pole and back – each year! Miniature transmitters have revealed that they follow zigzagging routes and rack up to 71,000 kilometres annually!
