World Migratory Bird Day 2022 Theme to Focus on Light Pollution

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.  

Solutions to light pollution are readily available. For instance, more and more cities in the world are taking measures to dim building lights during migration phases in spring and autumn. Best practice guidelines are also being developed under the Convention on Migratory Species (CMS) to address this growing issue and ensure that action is taken globally to help birds migrate safely.
