In his photography he tells the stories of charismatic animal species (preferably big birds) that give a face to the threat of extinction or to their severely endangered habitats. In that pursuit he portrayed Whooping Cranes in the endless wetlands of Canada, European Bisons in the last primeval forests of Europe, flamingos in the tropical coastlands of the Yucatan and Saiga antelopes in Kazakhstan’s steppes among others. Klaus calls himself a „slow“ photographer, returning again and again to the same places and animals thus achieving an intimate relationship with his subjects. Although the threats to nature are omnipresent he still passionately enjoys highlighting the pure beauty of wilderness with his camera.

He has published five books: including Kamchatka – eagles, bears, and volcanoes; Adlerleben – the American bald eagle; Return of the Emperor – European Bisons in the primeval forests of Poland; Kranich – European Cranes, and Whooping Crane.

Klaus is a committed member  of the international wildlife photography community. As a former president of GDT (the association of German wildlife photographers) he founded the International Nature Photo Festival 20 years ago in his hometown Luenen, Germany,  and still he very much enjoys lecturing at photo festivals all over the world. Klaus is a fellow of the International League of Conservation Photographers ILCP.

As much as he likes to travel to remote places he always loves to return and feel home in his house and garden in Luenen, Germany.
