The work is in three movements: The bog opens with a flute duet, after which the other woodwinds join in, followed by the birds. The second movement, Melancholy, features a slowed-down recording of the song of the shore lark. The final movement, Swans migrating, takes the form of a long crescendo for orchestra, with the sounds of whooper swans. At the end both birdsong and orchestra fade, as if into the distance.
