World Migratory Bird Day 2024

Saturday May 11

World Migratory Bird Day (Bird Day) celebrates a migratory bird’s spectacular migration between winter and summer grounds. Bird Day is a project of Environment for the Americas and was created in 1993 to focus attention on the need to conserve birds and their habitats.


Each year, Bird Day has an official theme. This year, it will focus on the topic of "Insects" and their importance for migratory birds.

In 2024, World Migratory Bird Day will be celebrated on two days, 11 May and 12 October, aligning with the cyclic nature of bird migration in different hemispheres. For more information, and resources, visit
