The importance of designing and managing urban environments that support both birds and people is the message of this year’s World Migratory Bird Day, a global campaign organized by the United Nations and international partners. The campaign kicks off with this year’s first peak day on 10 May 2025. Under the theme “Shared Spaces: Creating Bird-Friendly Cities and Communities,” the campaign urges collective efforts to secure the future of migratory birds in and around urban environments amid alarming bird population declines.
