Long-tailed Duck

      Clangula hyemalis

      Information

      The Long-tailed Duck is one of the most fascinating Nordic duck species. The males are very impressive with their elongated tail feathers, which are especially visible during the courtship display. The black-and-white breeding plumage is only worn until April. After that the Long-tailed Ducks moult into their mainly brownish non-breeding plumage. In autumn, males change their plumage a third time. The diving performances of the Long-tailed Duck are remarkable: It is able to dive to depths of 50 metres and to remain submerged for up to two minutes.
