ARCTIC TERN : AMAZING MIGRATORY BIRD :-

Each year the Arctic Tern performs the longest known migration of any animal on earth; from the breeding grounds in Greenland to Antarctica. Annual round trip of the Arctic Tern is app. 71,000 kilometers. 

As the Arctic Tern can live for over 30 years, the total distance flown in a tern’s lifetime may exceed 2.4 millions kilometers. That is equivalent to around 3 return journeys to the moon. The Arctic Tern is a small bird with a mass of a little over 100 grams.
