World Migratory Bird Day (WMBD) celebrates the phenomenon of bird migrations and raises awareness of the challenges birds face during their journeys. It serves as a call to action for bird conservation and connects people to birds around the world. WMBD is officially celebrated on the second Saturday in May (May 9th, 2020) in the U.S. and Canada and on the second Saturday in October (Oct. 10, 2020) in Latin America and the Caribbean. Because birds do not migrate on one day, however, events and programs are hosted year-round.Learn more¬†about the program’s 25 year history.
