Common tern

The common tern is very similar to the Arctic tern. The common tern has a longer beak, legs, head and neck and slightly bigger wings. In summer, the beak is orange-red with a black tip, the underside is a pale grey with little to no contrast to the white cheeks, the tail feathers do not reach beyond the wing tips, the primary feathers are white below and the rear edge of the wing is widely or disjointedly darker. In winter, the forehead and underside are white, the front edge of the wing bend is dark and the beak is entirely black.
