Fjordternen er en 36 cm stor terne, der findes i det meste af Asien, i den nordlige del af Nordamerika og i det meste af Europa. Den danske bestand af ynglende fjordterner udgør omkring 1000 par, med de største kolonier i Vestjylland, bl.a. ved Vadehavet og Nissum Fjord, men også på det centrale Sjælland og i Roskilde Fjord kan man se den.

Field marks

Slim, 36 cm with pale grey upperparts, a solid black and a forked white tail; the best mark is the orange-red bill with a black tip. When it stands, its tail does not reach past the folded wings.

Can be confused with

  • Arctic Tern — Arctic Tern has an all-red bill with no black tip, shorter legs, a smaller head and thinner neck, greyer underparts — and the tail projects beyond the folded wingtips. All the Arctic’s flight feathers are translucent against the light; on the Common Tern only the four innermost are.

Voice

Its alarm, a sharp "KEE-yah", puts the weight on the first part; also a "keeur" when arriving at the nest with a fish, a short "kip" in contact, and an angry "kakakakaka" when attacking.
