World Migratory Bird Day

World Migratory Bird Day (WMBD) is an annual awareness-raising campaign highlighting the need for the conservation of migratory birds and their habitats. It has a global outreach and is an effective tool to help raise global awareness of the threats faced by migratory birds, their ecological importance, and the need for international cooperation to conserve them.

World Migratory Bird Day was initiated in 2006 by the Secretariat of the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) in collaboration with the Secretariat of the Convention on the Conservation of Migratory Species of Wild Animals (CMS).

Originally, the idea of designating a day for migratory birds arose in the United States in 1993, when the US Fish and Wildlife Service, the Smithsonian Migratory Bird Center and the Cornell Laboratory of Ornithology initiated celebrations of the ‘International Migratory Bird Day’ (IMBD), which encourages bird festivals and education programmes across the Americas. Although this day was and continues to be successfully celebrated in the western hemisphere, something similar was missing for the rest of the world.

The two peak days of World Migratory Bird Day 2023 will be 13 May and 14 October, reflecting the cyclical nature of bird migration with varying migration periods in the northern and southern hemispheres.
