The Arctic tern can fly from the Arctic to the Antarctic and back, following summer across the planet.

Why it matters

The idea in context

National Geographic describes a journey longer than about 30,000 kilometres (18,600 miles), because the birds follow wind, food and weather rather than a ruler-straight line. Migration turns the whole Earth into a seasonal map.

Aynı kart, başka bir dilde.

Kutup sumrusu, yazın peşinden dünyanın bir ucundan diğer ucuna uçabilir: Kuzey Kutbu'ndan Antarktika'ya, sonra yeniden geriye.

National Geographic'e göre bu yolculuk, kuşlar düz bir çizgi izlemediği için yaklaşık 30.000 kilometreden (18.600 milden) daha uzundur. Rüzgârı, yiyeceği ve mevsimi takip ederler. Göç burada yalnızca yer değiştirmek değildir; gezegenin tamamını canlı bir takvime çevirmektir.

National Geographic Society describes the Arctic tern's Arctic-to-Antarctic migration and notes that the route is longer than the roughly 30,000-kilometre (18,641-mile) pole-to-pole distance because the birds do not fly straight.
