World Migratory Bird Day in October takes place on 11 October 2025, the second Saturday of the month. It is supported by the United Nations through CMS and AEWA and has been observed biannually since 2018.
The October observance highlights the autumn migration, when birds travel from their breeding grounds in the North to wintering areas in the South. It draws attention to the need for protected routes and rest areas along these long-distance journeys.
World Migratory Bird Day in October raises awareness about international cooperation to safeguard migratory species throughout their life cycles. Activities on this day often include habitat restoration projects, scientific talks and public outreach initiatives.
The first observance each year takes place in spring: World Migratory Bird Day in May is celebrated on the second Saturday of May each year and focuses on the northbound journey to breeding grounds.
