Common tern

The common tern is a seabird in the family Laridae with a circumpolar distribution, its four subspecies breeding across temperate and subarctic regions of Europe, Asia and North America. It is strongly migratory, wintering in coastal tropical and subtropical regions, and breeding adults show light grey upperparts, pale underparts, a black cap, orange-red legs and a narrow pointed bill that is mostly red with a black tip or entirely black depending on subspecies.
