World Migratory Bird Day is officially celebrated on the second Saturday in May (May 13th in 2023) as migratory birds journey to nesting sites and on the second Saturday in October (October 14th in 2023) as they return to wintering areas.
In 1993, the Smithsonian Migratory Bird Center created International Migratory Bird Day (IMBD). This educational campaign focused on the Western Hemisphere celebrated its 25th year in 2018. Since 2007, IMBD has been coordinated by Environment for the Americas (EFTA), a non-profit organization that strives to connect people to bird conservation.
In 2018, EFTA joined the Convention on Migratory Species (CMS) and the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) to create a single, global bird conservation education campaign, World Migratory Bird Day. WMBD celebrates and brings attention to one of the most important and spectacular events in the Americas – bird migration.
This new alliance furthers migratory bird conservation around the globe by creating a worldwide campaign organized around the planet’s major migratory bird corridors, the African-Eurasian flyway, the East Asian-Australasian flyway, and the Americas flyway.
EFTA will continue to focus its efforts on the flyways in the Americas to highlight the need to conserve migratory birds and protect their habitats, and will continue to coordinate events, programs, and activities in Canada, the United States, Mexico, Central and South America, and the Caribbean at protected areas, refuges, parks, museums, schools, zoos, and more. As many as 700 events and programs are hosted annually to introduce the public to migratory birds and ways to conserve them.
