World Migratory Bird Day is now celebrated twice a year, on the second Saturday in May and October.
Observing this day raises awareness and emphasizes the importance of protecting migratory birds and their habitats.
In 1993, the US Fish and Wildlife Service, the Smithsonian Migratory Bird Center and the Cornell Laboratory of Ornithology began celebrations of this day.
Theme of 2023 is ‘Water and its importance for migratory birds’.
Globally, at least 4,000 species of birds are regular migrants, which is 40 percent of the total birds in the world.
