Arctic Tern, sterna paradisea, preparing to mate and nest in the Arctic scientific research village of Ny-Alesund, Svalbard. Two Arctic Terns, sterna paradisea, perched near the dog yard Ny Alesund, Svalbard. These terns migrate more than any other species bird – up to 35,000km per year for some birds, as the travel to Antarctica and back, and can enjoy two polar summers.
