a Good half-hour before sunset, it will be full. Two buses and about a dozen cars parked along the road between the North Frisian rosary and the Danish Ruttebüll on Ruttebüller See.

people with binoculars and big cameras are positioned on the reed-covered shore of the lake. Two women make it on their rollators convenient. On the other side of the road the sun is slowly disappearing behind a field.

The visitors are waiting for a spectacle that is mentioned in the Danish “Sort Sol”: the Black sun. It is a natural phenomenon that takes place every year in early spring and in late summer and autumn in the Region: hundreds of thousands of starlings gather here on the journey between the breeding areas in the North and the warm winter quarters in more southerly climes – until they blow up suddenly and in huge swarms, the sun will darken.

Hans Peter Wendicke lives for decades on the Danish side at the Ruttebüller the lake and the unit is still in raptures when he speaks of the “Black sun”. “It is a fantastic phenomenon,” he says. The 86-Year-old leads groups of visitors to the places where the starlings “dance”.

Sometimes, the hobby will need to take ornithologist an arduous journey through rough terrain. This evening at the end of March, you’re in luck: The birds have chosen for your grid a well-visible place on the Ruttebüller see. Initially, the first small flocks flying over the lake. More to follow. The chirping of the birds in the reeds louder. And at some point, it is to the extent that: masses of birds rise into the air, forms fantastic Shapes in the air.

The fly in the swarm protects against attackers from the air. Sometimes, the starlings seem to be the birds of prey is also one of spite, as Wendicke told: you let the attacker in an Opening in their Formation flying, castles, this, and splattered the bird of Prey as long as with the feces, to this case to the ground.
