Artificial light at night causes disorientation, collision, and death in seabirds during breeding seasons. Mitigation measures protect millions of birds annually.
Seabirds grounded by light pollution often suffer injuries from collisions with structures. Those that land on roads or urban environments face predation, vehicle strikes, and dehydration before rescue. Light pollution mitigation - shielding fixtures, switching to amber LED where possible near colonies - directly prevents this suffering.
