Here's how to experience the Black Sun

Especially in autumn crowds of starlings are gathering for the flight return to the South and in spring they will come back again. They are flying closed together, lined up in dancing formations to confuse their enemies, the birds of prey. This phenomenon has got the name "black sun".

In the tourist information we get a lot of questions that go: "How do we experience black sun?"

In short, you can be lucky to see the Black Sun in almost the entire Wadden Sea area, as long as there is plenty of space and green open plains, the large flocks of starlings lands and takes off many times before they settles for the night, this remarkable dance is what we call the Black Sun

  • Aventoft, near the border
  • South of Højer floodgate
  • Vest of Skærbæk
  • Borderlands near Rudbøl
  • Ballum
The red fields are where one can often encounter Black sun

The starling in Denmark

The starlings come from all the countries around the Baltic Sea and Norway. Just before the starlings descend into the tube forests for the night, the large flocks draw fascinating patterns in the sky - this is called black sun and can be experienced in the marsh at Höjer.

Black sun end each evening with the starlings settling in the eaves, usually up to an hour before sunset.

The accommodations are constantly being moved to cheat birds of prey, and because rooftops after a few days of use rupture, the starling literally sits with its feet in water.


Black sun in the Tønder marsh can sometimes hold up to a million birds. However, when the overnight flock becomes larger than 500,000 birds, the flock usually splits up as there is too much unrest.

The dance of the stars is determined by the number of birds of prey and the weather. The optimum conditions are a relatively quiet and dry evening, as well as a suitable number of birds of prey, which help create the beautiful formations in the sky. On a stormy and rainy evening without birds of prey, the starlings dive down fairly quickly and go to rest for the night in the tube forest.

In the spring and autumn, flocks of thousands are seen
