World Migratory Bird Day (WMBD) is an awareness-raising campaign highlighting the need for the conservation of migratory birds and their habitats. It aims to draw attention to the threats faced by migratory birds, their ecological importance and the need for international cooperation to conserve them.
Every year people around the world take action and organize public events such as bird festivals, education programmes, exhibitions and bird-watching excursions to celebrate WMBD. All these activities can also be undertaken at any time of the year as countries or regions observe peak migrations at different times, but the main days for the international celebrations are on the second Saturday in May and in October.
