This video is from a boat trip to the seabird colonies of Røst in outer Lofoten. They are home to the largest population of sea eagles in the world and also the largest seabird colonies in Europe.
There is one post directly related to this video, The seabird colonies at Røst. That post is also found on the Norwegian language part of Sandalsand, here. In English, here and here, you will found two other articles related to Røst. They are kind of introductions to what you may discover on the bird cliffs.
