The upperwings are pale grey, with the area near the wingtip being translucent. The tail is white, and the underparts pale grey. Both sexes are similar in appearance.
The arctic tern is K-selected, caring for and aggressively defending a small number of young. Parents feed them fish for a considerable time, and help them fly south to winter. Arctic terns are long-lived birds, with many reaching twenty years of age. They eat mainly fish and small marine invertebrates. The species has an estimated one million ...

The Arctic tern migrates the greatest distance of any bird. Seabird migration is similar in pattern to those of the waders and waterfowl. Some, such as the black guillemot Cepphus grylle and some gulls , are quite sedentary; others, such as most terns and auks breeding in the temperate northern hemisphere, move varying distances south in the ...
