World Migratory Bird Day (WMBD) is a biannual global awareness-raising campaign highlighting the need for the conservation of migratory birds and their habitats. Every year, on the second Saturday in May and October, dedicated people and organizations around the world celebrate World Migratory Bird Day by arranging activities such as bird festivals, education programmes, exhibitions and bird-watching excursions. Event organizers are encouraged to register their events at the WMBD website.
