Arctic Tern in flight (Sterna paradisaea) - Nome, AK

I saw many Aleutian and Arctic Terns during my trip. This Arctic Tern was cooperative for a flight shot. I wonder if terns know how elegant they are?

 

This bird migrates from the Arctic where it breeds to spend the winter in Antartica and flies about 40,000km. It is the farthest yearly journey of any bird. Just incredible!
