Every year, billions of birds vanish from one part of the world and magically reappear in another — and the science behind it will blow your mind!

World Migratory Bird Day is celebrated twice a year — on the second Saturday of May and October — to raise awareness about the incredible journeys migratory birds make across continents and oceans. In 2026, the theme focuses on the importance of shared ecosystems and how birds connect the world together. These feathered travellers do not carry maps or GPS, yet they navigate thousands of kilometres with stunning accuracy, using the stars, the sun, Earth's magnetic field, and even familiar landmarks to find their way.
Singapore sits along one of the world's most important migratory flyways — the East Asian-Australasian Flyway. This invisible highway in the sky stretches from Arctic Russia and Alaska all the way down to Australia and New Zealand, passing right over Singapore and the rest of Southeast Asia. Every year, species such as the Asian Dowitcher, the Chinese Egret, and various species of sandpipers and waders stop at Singapore's wetlands, mudflats, and reservoirs to rest and refuel before continuing their epic journeys. Places like Sungei Buloh Wetland Reserve are critical pitstops for these exhausted travellers, making Singapore a vital link in a global chain of habitats.
Migration is one of nature's greatest feats, but it is also incredibly dangerous. Birds must survive storms, cross vast deserts, avoid predators, and find enough food along the way. Sadly, human activity has made the journey even harder. Habitat destruction, light pollution from tall buildings — which confuses birds at night — climate change altering food availability, and illegal hunting all threaten migratory species. Some populations have declined by over 70 percent in recent decades, sending alarm bells ringing among scientists worldwide.
The good news is that people everywhere, including students in Singapore, can help! Reducing unnecessary outdoor lighting during migration seasons, supporting wetland conservation, keeping cats indoors, and learning to identify local bird species are all meaningful actions. Organisations like the Nature Society Singapore run birdwatching events and citizen science programmes where young people can record sightings and contribute real data to conservation efforts. When you protect a mudflat in Singapore, you are helping a bird that may have hatched in Siberia and is heading to Australia — proof that every small action truly connects the whole world.
