Where to see them

Did you know…?

  • Juveniles can spend three to five years in practically continuous flight over the ocean, settling neither on water nor on land: they sleep on the wing and only come down when they return to breed.

    From

  • Its tropical colonies are deafening and its ceaseless call has earned it the English nickname "wideawake" — the one that keeps you up.

    From

  • GPS tracking studies have shown it can cover up to 90,000 km a year by following favourable wind patterns.

    From

  • It eats small fish such as herring and capelin, and crustaceans such as krill.

    From

  • It lives on open tundra, boreal forest and rocky coasts of the circumpolar Arctic.

    From

  • Its chicks form crèches of hundreds of birds, and each adult finds its own in the crowd by recognising its voice: the identification is so precise that a parent can feed its chick among a thousand without error.

    From

  • It breeds in extremely tight colonies where the nests are less than thirty centimetres apart, a density that reduces predator success by swamping them.

Its intensely orange bill distinguishes it from the lesser crested tern, which is smaller with a paler orange bill and shares many of its African colonies.
