"Arctic Tern," Wikipedia, the free encyclopedia. The Arctic tern is a medium-sized bird around 3336 cm (1314 in) from the tip of its beak to the tip of its tail. The wingspan is 7685 cm (3033 in). The weight is 86127 g (3.04.5 oz). The beak is dark red, as are the short legs and webbed feet. Like most terns, the Arctic tern has high aspect ratio wings and a tail with a deep fork. The adult plumage is grey above, with a black nape and crown and white cheeks. 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 winter plumage is similar, but the crown is whiter and the bills are darker.
