Bonn, 9 December 2021 - Light Pollution will be the focus of the World Migratory Bird Day 2022 campaign.
Artificial light is increasing globally by at least 2 per cent per year and it is known to adversely affect many bird species. Light pollution is a significant threat to migratory birds, causing disorientation when they fly at night, leading to collisions with buildings, perturbing their internal clocks, or interfering with their ability to undertake long-distance migrations.
