Ringed migratory waders resighted on Kerala coast
Why in News?
A whimbrel ringed six years ago resurfaces in Kerala: the flyway UPSC keeps asking about
A ringed Eurasian whimbrel and a marked Tibetan sand plover were resighted on the Kerala coast, both Central Asian Flyway migrants.

Bird researchers on the Kerala coast resighted an Eurasian whimbrel that had been ringed six years earlier, along with a marked Tibetan sand plover, both long-distance migratory waders.
Such ringing recoveries help scientists trace routes and stopover sites along the Central Asian Flyway, a major bird migration corridor linking Arctic and Central Asian breeding grounds to wintering areas in South Asia.
Coastal wetlands and mudflats, such as those along Kerala's shoreline, serve as crucial stopover and wintering habitats for such migratory shorebirds.

Key facts
Remember these
- A ringed Eurasian whimbrel, tagged six years earlier, was resighted on the Kerala coast
- A marked Tibetan sand plover was also resighted along the same coast
- Both are long-distance migratory waders using the Central Asian Flyway
- The Central Asian Flyway links Arctic and Central Asian breeding grounds to South Asian wintering areas
- Kerala's coastal wetlands and mudflats serve as key stopover and wintering habitats

How the exam will ask it
Prelims
- Ringing recoveries help scientists trace migration routes and stopover sites of birds.
- The Central Asian Flyway connects breeding grounds in the Arctic and Central Asia to wintering areas in South Asia.
- Coastal wetlands and mudflats act as crucial stopover and wintering habitats for migratory shorebirds.
Mains
GS Paper 3 (Environment and Biodiversity): the resighting of ringed waders on the Kerala coast highlights the ecological importance of coastal wetlands as stopover habitats along the Central Asian Flyway. Unregulated coastal development and wetland degradation threaten these migratory corridors, underscoring the need for wetland conservation under frameworks like the Ramsar Convention and stronger coastal zone regulation.
Quick recall
Answer before you reveal
Migratory birds such as the Eurasian whimbrel and Tibetan sand plover, recently recorded on the Kerala coast, travel along which flyway linking their breeding grounds to South Asia?
- Central Asian Flyway
- East Asian-Australasian Flyway
- Atlantic Flyway
- Pacific Americas Flyway
Show answer
Answer: A — Correct: Central Asian Flyway - links Central/North Asian breeding grounds to South Asian wintering sites like Kerala's coast. • East Asian-Australasian Flyway - wrong: connects Siberia to Australia/New Zealand, a different corridor. • Atlantic Flyway - wrong: an Americas-Europe-Africa corridor. • Pacific Americas Flyway - wrong: runs along the Americas' Pacific coast.
