The Central Asian Flyway (CAF) is one of the world’s major migratory bird routes. It connects the breeding grounds of birds in Russia, Siberia, Central Asia and the Arctic region with wintering grounds in South Asia, West Asia and the Indian Ocean region.
It is important for India because India lies at the heart of this flyway. Many migratory birds that breed in colder northern regions visit Indian wetlands, grasslands, coasts, lakes, rivers and floodplains during winter.
Route and Geographical Spread
The Central Asian Flyway covers a large area between the Arctic Ocean and the Indian Ocean.
It includes countries across:
- Central Asia
- South Asia
- West Asia
- parts of Europe and Russia
- Indian Ocean region
India is a major wintering ground in this flyway because of its wide range of habitats, including Himalayan wetlands, Gangetic floodplains, desert wetlands, coastal lagoons, mangroves, mudflats and peninsular lakes.
Important Indian habitats linked with CAF include Chilika Lake, Keoladeo National Park, Harike Wetland, Pong Dam Lake, Sambhar Lake, Loktak Lake, Point Calimere, Pulicat Lake, Wular Lake, Nal Sarovar and the Yamuna floodplains.
Species and Ecological Importance
The flyway supports several migratory waterbirds, raptors, cranes, storks, ducks, geese, shorebirds and passerines.
Important migratory birds using this route include:
- bar-headed goose
- demoiselle crane
- Siberian crane historically
- northern pintail
- common teal
- ruddy shelduck
- greater flamingo
- black-tailed godwit
- Eurasian curlew
- various sandpipers and plovers
The flyway is ecologically important because migratory birds connect distant ecosystems. A bird may breed in Siberia, stop at Central Asian wetlands and winter in India. This means damage to one habitat along the route can affect the entire migration cycle.
For India, CAF highlights the importance of protecting not only famous national parks but also ordinary wetlands, mudflats, village tanks, floodplains and coastal feeding grounds.
India’s Role and Conservation Framework
India has prepared a National Action Plan for Conservation of Migratory Birds and their Habitats along the Central Asian Flyway. It focuses on habitat protection, species monitoring, international cooperation and reduction of threats along the flyway.
India is also a party to the Convention on Migratory Species (CMS) and the Ramsar Convention, both of which are relevant for CAF conservation.
The Central Asian Flyway is especially important for wetland governance because many migratory birds depend on wetlands that are outside protected areas. Therefore, conservation requires coordination between forest departments, wetland authorities, local bodies, agriculture departments and urban planners.
Specific Concerns
The main threat to CAF birds is the loss and degradation of stopover and wintering habitats.
In India, major concerns include:
- wetland encroachment
- sewage and industrial pollution
- conversion of marshes and mudflats
- decline of river floodplains
- disturbance from tourism and boating
- power-line collision for large birds
- hunting and trapping in some regions
- climate-linked changes in water availability
The problem is that migratory birds need a chain of safe habitats. If one key wetland dries up, becomes polluted or is converted, the bird’s entire journey becomes more difficult.
Urban wetlands are especially vulnerable. The Yamuna floodplains, Najafgarh Jheel region and Delhi wetlands show how migratory bird habitats can survive inside cities but remain under constant pressure from construction, waste dumping and polluted water.
Conclusion
The Central Asian Flyway is a major migratory bird route linking northern breeding grounds with wintering areas in South Asia and the Indian Ocean region.
India is central to this flyway because it provides wintering and stopover habitats for many migratory birds.
Its conservation depends on protecting wetlands, floodplains, mudflats and coastal habitats, not only inside protected areas but also in ordinary landscapes used by birds during migration.
