Yellow-billed Loon

      Gavia adamsii

      Information

      The Yellow-billed Loon spends almost all year in remote areas of the High Arctic so that any sighting of this species is a lucky coincidence. Its distribution has not yet been sufficiently studied. This largest member of the loon family distinguishes itself in all its plumages by its pale-yellow and very strong bill. When diving, the Yellow-billed Loon often remains under water for more than a minute and is able to cover quite a distance. After foraging, it often rests for quite a while and can occasionally be admired even close to the shore.
