Bharatpur, Rajasthan | September 12, 2026
For generations, the arrival of the elegant Siberian Crane at Rajasthan’s Keoladeo National Park was one of the great spectacles of India’s winter bird migration. The brilliant white cranes travelled thousands of kilometres from their breeding grounds in western Siberia to spend the colder months in the wetlands of Bharatpur.
Then they disappeared.
It has now been about a quarter of a century since Siberian Cranes last wintered in India, and conservationists increasingly fear that the historic migration to Bharatpur has been lost. The Central Asian flock that once undertook this extraordinary journey is considered to have practically disappeared.
From dozens of cranes to a solitary pair
The decline was dramatic.
Keoladeo was once the last consistently confirmed Indian wintering ground of the Siberian Crane. Historical counts show around 80 birds in the 1960s, although some earlier estimates were even higher.
By the 1984–85 winter, 41 cranes were recorded. Numbers subsequently collapsed, and there were winters during the 1990s when none appeared at all.
Eventually, only a pair remained.
The winter of 2001–02 marked the last confirmed appearance of the Siberian Crane at its traditional Indian wintering ground. In 2002–03 the birds failed to arrive, and they have not subsequently been confirmed anywhere in India.
For birdwatchers who once waited every winter for the cranes’ return, their absence has become permanent enough for an entire generation of Indian bird enthusiasts never to have seen a wild Siberian Crane in the country.
An extraordinary 5,500-km migration
The cranes that reached India belonged to the Central Asian flock of the Siberian Crane.
Their migration was extraordinary.
The birds bred in the lowlands of the Ob River basin in western Siberia before travelling roughly 5,500 kilometres southwards.
Their traditional migration route crossed Russia, Kazakhstan, Uzbekistan, Turkmenistan, Afghanistan and Pakistan before finally reaching India and the wetlands of Keoladeo.
This immense journey also made the population exceptionally vulnerable.
Protecting the birds at Bharatpur alone could never guarantee their survival. Every wetland, feeding site and stopover along thousands of kilometres of migration had the potential to determine whether they reached India safely.
Hunting along the migration route took a heavy toll
There is unlikely to have been a single reason for the disappearance.
Hunting along the Central Asian migration route is considered one of the major factors behind the collapse.
The cranes had to pass through regions of Afghanistan and Pakistan where hunting pressure at important migration and stopover areas posed a serious threat.
Wetland degradation compounded the problem. As wetlands disappeared or deteriorated, the birds lost places where they could safely rest and feed during their enormous journey.
For a population already reduced to only a handful of individuals, the loss of even a few adult birds could have devastating consequences.
Problems at Bharatpur added to the crisis
Conditions at the cranes’ Indian destination also changed.
Keoladeo is an extensively managed wetland whose ecological health depends heavily on an adequate supply of water.
The winter of 2002–03 was preceded by what the Convention on Migratory Species describes as the worst drought in the park’s history, leaving the wetland completely dry. That was also the winter when the cranes failed to return.
Keoladeo subsequently experienced serious water shortages, although the disappearance of the cranes cannot be attributed solely to conditions inside the park.
By then, the migratory population itself had already been reduced to critically low numbers.
The population that came to India effectively vanished
This is the crucial reason hopes of a natural return are now so faint.
The Siberian Cranes that once reached Bharatpur were not simply birds that decided to take another route to another Indian wetland.
They represented a distinct migratory flock whose numbers progressively collapsed.
The Convention on Migratory Species says the Central Asian flock has practically ceased to exist.
Without surviving birds carrying knowledge of the traditional migration route between Siberia and India, restoring that ancient journey becomes extraordinarily difficult.
Migration in cranes is partly learned: young birds travel with experienced adults and acquire knowledge of routes and stopover locations.
When the last experienced birds disappear, a migration route built up over generations can disappear with them.
Siberian Cranes survive—but largely on another flyway
The disappearance from India does not mean the Siberian Crane itself has vanished from the planet.
The great majority of surviving Siberian Cranes belong to the eastern population, which breeds in northeastern Siberia and migrates to China.
It is the western and central populations that suffered catastrophic declines.
This distinction is important because the existence of thousands of Siberian Cranes elsewhere does not automatically mean birds will eventually rediscover the ancient Bharatpur migration route.
The Indian flock followed its own traditional flyway across Central and South Asia.
The loss of more than a bird
The disappearance of Siberian Cranes from Bharatpur represents something larger than the local extinction of a spectacular winter visitor.
It demonstrates how fragile long-distance migration can be.
A protected wetland may be perfectly capable of supporting a species, but migratory birds must survive landscapes stretching across countries and continents before reaching it.
A broken link thousands of kilometres away can empty an otherwise protected sanctuary.
Keoladeo continues to host enormous numbers of migratory waterbirds every winter. But one unmistakable visitor is missing.
The tall white Siberian Cranes that once walked through Bharatpur’s shallow marshes have not returned since the beginning of this century.
Their traditional 5,500-km journey from Siberia to India—repeated by generations of cranes—has effectively fallen silent.
And after roughly 25 winters without them, the story of India’s Siberian Crane is increasingly becoming not one of waiting for their return, but a powerful warning about how an ancient animal migration can disappear within a human lifetime.
