The night is for sleeping? Not for all creatures: More than half of all animals are active during twilight or at night. The research team on light pollution from IGB, the StadtNatur association and the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) invite you to participate in the "Living Night" photo competition to draw attention to this fascinating diversity and to raise awareness of the importance of protecting nocturnal landscapes. Photograph nocturnal and crepuscular species, find artificial light sources and win great prizes. All information at www.stadtwildtiere.de.
