Bonn/Boulder/Incheon, 8 May 2026 – As millions of migratory birds cross continents and oceans, people across the planet are preparing to mark World Migratory Bird Day 2026, with the first peak day for the year taking place on Saturday, 9 May 2026.
This year’s campaign is guided by a simple but powerful message: “Every Bird Counts – Your Observations Matter!” – highlighting the importance of community science (also referred to as citizen science) in safeguarding migratory birds along all the world’s flyways.
World Migratory Bird Day is a UN-backed, global awareness-raising campaign coordinated by four international partners: the Convention on the Conservation of Migratory Species of Wild Animals (CMS), the Agreement on the Conservation of African Eurasian Migratory Waterbirds (AEWA), the East Asian–Australasian Flyway Partnership (EAAFP) and Environment for the Americas (EFTA). Together, these organizations unite governments, scientists, communities and individuals around a shared mission – to raise awareness on the need to conserve migratory birds and the habitats they depend on, and to highlight the importance of international cooperation.
