What is Black Sun.

Black Sun is a natural phenomenon where the starlings gather in large flocks to spend the night. The collection is done mainly to protect themselves from birds of prey. The birds of prey have a hard time catching prey when the birds gather in groups of up to 1.5 million birds.

"The season for Black Sun is from late August to late October and again from March to April."

However, you can easily experience black sun in November and December, but not to the same extent as you can in high season.

Black Sun always plays out by sunrise and sunset. as a spectator you will often experience Black Sun in the evening before sunset. During these hours you will see groups of starlings fly in and sit in the high reeds to spend the night, the size of the groups varies from about a thousand up to several hundred thousand.

There is not an evening where Black Sun is the same, as the whole show depends on how the birds of prey hunt that particular day. If the birds of prey attack the large flocks, you will find that the birds repeatedly sit down and fly.

Things that make the experience a little better.

If you attend guided tour

If you choose to go on a guided tour, you do not have to get stuck in trafic and then find a free parking space, because the traffic is very dense as long as there is black sun. In addition, you also save hours looking for the many stars.

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.

How many stares can you be in a bunch

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
