Once known for the mass trapping of migratory birds, a remote corner of northeast India now hosts one of the world’s most remarkable conservation turnarounds.
On an October evening beside the Doyang Reservoir in India’s Nagaland state, the sky begins to darken long before sunset. At first, the movement overhead resembles smoke drifting across a hillside. Then the shapes resolve into birds. Tens of thousands of them. Within minutes, the flock swells into the hundreds of thousands as Amur falcons stream towards their roosting trees. The spectacle is so vast that local observers often stop speaking altogether.
For a few weeks each autumn, the forests around Pangti village become the centre of one of the greatest avian gatherings on Earth.
The birds have travelled thousands of kilometres from breeding grounds in eastern Russia and northern China. They are heading for southern Africa, undertaking a migration of more than 20,000km. Yet it is not the journey itself that has transformed Nagaland’s reputation.
It is what happened when people decided to stop hunting them.
From slaughter to sanctuary
The story begins with an uncomfortable truth.
In 2012, conservationists documented the large-scale trapping of Amur falcons around the Doyang Reservoir. Nets stretched across hillsides and valleys. Thousands of birds became entangled during their migration stopover.
Estimates suggested that well over 100,000 falcons may have been trapped during a single season. At the time, the birds were sold in local markets and consumed as food.
Photographs of the slaughter travelled rapidly through conservation networks. What had once been a little-known local practice suddenly became an international concern.
“The scale shocked everybody,” recalls Asad Rahmani, former director of the Bombay Natural History Society (BNHS), one of India’s oldest conservation organisations. Rahmani and colleagues helped draw national attention to the issue after evidence emerged from the region.
The Amur falcon is not globally endangered. The species is currently listed as Least Concern by the International Union for Conservation of Nature (IUCN). Yet the concentration of birds in Nagaland meant that intense hunting at a single site had the potential to affect a significant proportion of the global population.
That concentrated risk also created an unusual opportunity.
If conservationists could protect one landscape, they could safeguard extraordinary numbers of birds.
Why do the falcons gather here?
The Doyang Reservoir lies within a corridor rich in insects and sheltered forest.
Every autumn, Amur falcons arrive exhausted after crossing large stretches of Asia. They rest and feed intensively before beginning the most demanding stage of their migration: a non-stop flight across the Indian Ocean.
Scientists tracking birds with satellite transmitters have revealed journeys that border on the unbelievable. Some individuals cover more than 3,000km of open ocean in a single flight.
For the falcons, Nagaland functions rather like a motorway service station before a transcontinental drive.
“The birds need somewhere safe to refuel,” explains Dr Raju Kasambe, assistant director at BNHS and a leading researcher on migratory birds in India. “Disturbance during this period can have consequences far beyond the immediate area.”
Satellite-tracking studies published through collaborative international research projects have shown that birds stopping in Nagaland later disperse across large parts of southern Africa. The conservation value of the site therefore extends well beyond India’s borders.
The villagers who changed the story
Conservation success is often presented as a battle between local people and wildlife.
Pangti tells a different story.
Following the 2012 revelations, the Nagaland Forest Department, BNHS, local churches, village councils and conservation groups launched an intensive awareness campaign. Rather than relying solely on enforcement, they focused on community engagement.
Schoolchildren attended conservation programmes. Village leaders introduced restrictions. Former hunters became wildlife guardians.
One of the most influential voices came from within the community itself.
Local leaders began framing the birds not as a resource to be harvested but as guests undertaking one of nature’s great migrations.
The shift happened remarkably quickly.
Within a year, reports of mass trapping had fallen dramatically. Visitors who arrived expecting to document persecution instead witnessed villagers protecting roost sites.
The transformation has since become a case study in community-led conservation.
It is also a reminder that conservation outcomes often depend as much on social relationships as biological science.
A global responsibility
The Amur falcon’s migration links multiple nations.
Birds breed in Russia and China. They travel through Mongolia, India and several countries in Africa. No single government can protect them alone.
That is where international agreements matter.
The species is covered by the Convention on the Conservation of Migratory Species of Wild Animals, often known simply as the Convention on Migratory Species (CMS). The treaty encourages countries to cooperate in protecting animals that cross international borders.
Migratory species present a particular challenge for conservation.
A bird can spend one season in a protected landscape and the next in a place where protection is weak or absent. Success therefore depends on maintaining a chain of safe habitats across continents.
“The Amur falcon demonstrates why international cooperation is essential,” says Amy Fraenkel, Executive Secretary of the CMS. “Conservation cannot stop at political boundaries.”
The lesson extends beyond falcons.
Many migratory birds are declining globally as wetlands disappear, insect populations fall and climate change alters seasonal patterns.
Against that backdrop, Nagaland stands out.
Conservation and economics
Success has brought new questions.
Each year, birdwatchers, photographers and tourists travel to Doyang hoping to witness the migration.
The influx generates income for local communities.
Guesthouses have expanded. Guides offer birdwatching tours. Local businesses benefit from seasonal visitors.
Yet tourism presents its own risks.
Too many visitors in sensitive areas can disturb roosting birds. Conservationists therefore continue to advocate careful management of viewing locations and visitor numbers.
The challenge is familiar across wildlife tourism.
The same spectacle that attracts attention can be damaged by excessive attention.
For now, authorities have generally managed the balance well. Temporary restrictions and awareness campaigns help minimise disturbance during the migration season.
What happens next?
Standing beneath a roost tree at dusk, it is tempting to view the story as complete.
The birds are protected. The hunting has largely stopped. International recognition has followed.
Yet conservation rarely offers such tidy endings.
The falcons still depend on habitats scattered across half the globe. Climate change continues to reshape ecosystems along their migration route. Insect declines in parts of Asia and Africa raise fresh questions about future food supplies.
And success itself brings pressures, particularly as visitor numbers increase.
As darkness settles over the Doyang Reservoir, the last falcons spiral into the trees. Their calls merge into a continuous background chatter, like rain falling on distant leaves.
More than a million birds may gather here in a single season, creating one of the largest known roosts of any falcon species on Earth.
The achievement belongs not only to the birds, but to the people who chose to protect them.
Whether that choice endures for another decade, or another generation, remains the more important migration story.
