Singapore is at the intersection of two of the nine main migrant routes in the world.
The largest migrant road on Earth, which extends from the Arctic Circle to Australia’s and New Zealand’s southern approaches, is the East Asian-Australasian Flyway.
This route connects birds across great distances, and many species can be found navigating its vast area.
The Central Asian Flyway, one of the shorter but busiest relocation routes important for more than 600 insect species, is the second.
Birds travel for so long distances for life. Many people travel west in search of plentiful food sources, particularly to feed themselves, raise their children, and avoid the cold.
But the quest is becoming more deadly.
According to industrial and agricultural growth, ecosystems along the flyways are disappearing.
Brightly lit buildings also pose a threat because confused birds frequently collide with them, causing dangerous collisions.
Another growing danger is the changing environment.
Rising sea levels and unexpected weather are preventing migration routes, with professionals warning that unexpected climate changes, such as extreme cold or delayed snowstorms, can destroy bird populations.
