![]() ![]() Projects should consider the main sources of light pollution at a certain site, the likely wild species to be affected, and facts about proximity to important habitats and migratory pathways. The recommendations call for Environmental Impact Assessments to be conducted for projects that could result in light pollution. ![]() Two years ago, countries that are party to the CMS endorsed guidelines on light pollution covering marine turtles, seabirds, and migratory shorebirds. World Migratory Bird Day 2022 – Animated Promo Video - English "Seabirds such as petrels and shearwaters are attracted by artificial lights on land and become prey for rats and cats.” “Many nocturnally migrating birds such as ducks, geese, plovers, sandpipers and songbirds are affected by light pollution causing disorientation and collisions with fatal consequences," said Jacques Trouvilliez, Executive Secretary of the African-Eurasian Waterbird Agreement (AEWA), another UN treaty. With their energy reserves depleted, they risk exhaustion, or worse. Migrating birds are attracted to artificial light at night – particularly when there are low cloud conditions, fog, rain, or when flying at lower altitudes - luring them to dangers in cities.īirds become disorientated and, as a result, may end up circling in illuminated areas. Light pollution can cause birds to change their migration patterns, foraging behaviours and vocal communication, resulting in disorientation and collisions. A key goal of World Migratory Bird Day 2022 is to raise awareness of the issue of light pollution and its negative impacts on migratory birds,” said Amy Fraenkel, the CMS Executive Secretary.Īrtificial light alters natural patterns of light and dark within ecosystems, and contributes to the deaths of millions of birds each year. ![]() “Natural darkness has a conservation value in the same way as clean water, air, and soil.
