Sven had often walked the sandy shores of Amrum island. As the tide retreated, fish became concentrated in channels leading back to the sea. These were magnets for Arctic terns, which repeatedly flew high then dived down after the escaping fish.
Arctic terns have some of the longest migrations in the world. They take small fish from the surface of the water or by plunging into it. Populations are threatened by food shortages caused by increasing sea temperatures and overfishing.

Sven initially worked in the optical industry, as an engineer at Leica Camera AG - but his passion for wildlife photography and the ocean led him to search for another job, closer to the North Sea. He now lives on the island of Amrum in the German North Sea, and for 12 years has been teaching mathematics, physics and photography in a small school.
