Sanderling Bird Migration: Remarkable 7,400 km Journey to Narcondam Island

Sanderling: A Marathon Migration from South Australia

In a significant observation for avian research, a Sanderling (Calidris alba) was recently spotted on Narcondam Island, part of the Andaman and Nicobar archipelago, in April 2026. Scientific tracking revealed that the bird traveled an astounding 7,400 km from South Australia, highlighting the incredible endurance of these small shorebirds.

Migration and Habitat

• Breeding Grounds: Sanderlings are famous for their high-latitude migration, breeding in the Arctic Tundra.

• Wintering Areas: During the non-breeding season, they migrate between 3,000 to 10,000 km to sandy coasts across the globe, including Australia and Southeast Asia.

• IUCN Status: Currently classified as Least Concern, though they face threats from coastal habitat loss and climate change affecting their food sources.

Significance of the Sighting

Narcondam Island, an extinct volcanic island, provides a critical stopover for migratory birds traversing the East Asian-Australasian Flyway. For TNPSC and Environmental aspirants, this record is a prime example of international migratory connectivity and the importance of offshore island conservation.
