Attraction of petrels to artificial lights in the Canary Islands: effects of the moon phase and age class

摘要: The extent and intensity of artificial night lighting has increased with urban development worldwide. resulting light pollution is responsible for mortality among many Procellariiformes species which show nocturnal activity on their breeding grounds. Here, we report light-induced during a 9-year study (1998‐2006) Tenerife, the largest island Canary archipelago. A total 9880 birds from nine were found grounded, majority being Cory’s Shearwaters Calonectris diomedea (93.4%). For this grounded fledglings (96.4%), fall apparently while leaving nesting colony first time; smaller (storm-petrels) adult more often than fledglings. almost all species, grounding showed seasonal pattern linked cycle. Certain phases moon influenced Shearwater, reduced full moon. percentage attracted to lights in relation produced annually varied between years (0‐1.3% Madeiran Storm-petrel Oceanodroma castro; 41‐71% Shearwater). Mean rates also (from 0.4% European Hydrobates pelagicus 2.3% Manx Shearwater Puffinus puffinus). Here that are concern, at least petrels small shearwaters. Thanks efforts involving civil cooperation, 95% have been returned wild. To minimize impact recommend several conservation measures: continuing rescue campaigns, alteration signatures reduction emissions fledging peaks. Furthermore, monitoring program petrel populations be implemented, as well further studies assess fate released continued research address why lights.
