The spoon-billed sandpiper (Calidris pygmaea) is a tiny, critically endangered migratory shorebird, easily recognised by its flattened, spatula-shaped bill, that breeds on the Arctic coast of far-eastern Russia and spends the non-breeding season on tidal mudflats in South and Southeast Asia, including a few coastal sites in India. Its global population is estimated at only a few hundred birds, which makes every protected wintering and stopover site important.
In India, the spoon-billed sandpiper has been recorded in small numbers at coastal wetlands such as Point Calimere in Tamil Nadu, Chilika Lake in Odisha and parts of the Gulf of Mannar, and occasionally in the Sundarbans region. Conservation depends on international cooperation along the East Asian-Australasian Flyway, because the bird crosses many countries on its yearly journey of thousands of kilometres.

What is the spoon-billed sandpiper?
The spoon-billed sandpiper is a very small wader in the sandpiper family (Scolopacidae) that is best known for the spatula-like widening at the tip of its bill. At roughly the size of a sparrow, it is one of the smallest shorebirds that makes a long-distance migration across continents.
In breeding plumage, adults have a russet or reddish head, neck and breast with dark streaking, a dark back with pale edges and a white belly. In winter plumage, the bird turns pale grey above and white below, which makes it hard to tell apart from similar small waders such as the red-necked stint at a distance. The spoon-shaped bill is the most reliable feature when seen well.
The species was long placed in its own genus, Eurynorhynchus, but is now generally included in the genus Calidris along with other small sandpipers. Because of its small size and habit of feeding on large, open mudflats, the bird is difficult to spot and is one of the most sought-after sightings for birdwatchers.
Why does the spoon-billed sandpiper have a spoon-shaped bill?
The spoon-billed sandpiper has a spoon-shaped bill because the flattened tip helps it forage in soft, wet mud by sweeping the bill from side to side and trapping tiny prey. Researchers have suggested that the tip may help the bird detect and pick up small invertebrates in the surface layer of mud or shallow water.
The feeding style is distinctive. The bird often walks forward in a slightly crouched posture, with the bill held near the mud and moved in a sweeping arc, almost like a person using a vacuum nozzle. Prey includes small crustaceans, worms and other invertebrates on the mudflat surface, and on the breeding grounds insects and plant seeds.
The bill is a specialised adaptation, and it is also a conservation concern. A bird specialised for a particular habitat, soft intertidal mud, is more vulnerable when that habitat is reclaimed or degraded. Fine-scale research on feeding behaviour continues to help managers identify the best sites.
Where does the spoon-billed sandpiper breed and winter?
The spoon-billed sandpiper breeds on the coastal tundra of the Chukotka region and nearby areas of far-eastern Russia during the short Arctic summer, and winters in South and Southeast Asia. The breeding range is a narrow strip of sandy, lightly vegetated coastline along the Bering Sea and the Arctic Ocean.
After breeding, the birds travel south along the East Asian-Australasian Flyway, stopping at coastal staging sites in Russia, Japan, Korea and China, where they refuel on mudflats. Key stopover areas include the Yellow Sea coast. The main wintering areas lie in Bangladesh, Myanmar, Thailand, Vietnam, southern China and parts of eastern India.
India lies at the western edge of the species’ wintering range. The Gulf of Martaban in Myanmar and the coast of Bangladesh are believed to hold larger numbers than India does. Indian sites matter because they extend the bird’s choice of safe wintering habitat and may become more important if conditions elsewhere worsen.
Where is the spoon-billed sandpiper seen in India?
The spoon-billed sandpiper in India has been recorded mainly along the east coast, in sites such as Point Calimere Wildlife and Bird Sanctuary in Tamil Nadu, Chilika Lake in Odisha and parts of the Gulf of Mannar, with occasional reports from the Sundarbans and other coastal wetlands. Records are sparse and the numbers are usually just a few birds, so each sighting is notable.
- Point Calimere (Tamil Nadu): A coastal sanctuary with mudflats, lagoons and salt pans, designated a Ramsar site in 2002, and a major wintering ground for waterbirds.
- Chilika Lake (Odisha): Asia’s largest brackish-water lagoon, designated in 1981 as India’s first Ramsar site, hosting hundreds of thousands of migratory birds each winter.
- Gulf of Mannar (Tamil Nadu): A marine biosphere reserve and national park area with intertidal flats and islands along the southeastern coast.
- Sundarbans and other east-coast sites: Occasional reports from delta and coastal mudflat areas.
Because the birds are tiny and similar to other small waders, identification is difficult, and some records may be unconfirmed. Systematic surveys by ornithological groups, forest departments and bird-ringing programmes are the best way to establish how many spoon-billed sandpipers use India each year.
How many spoon-billed sandpipers are left?
Only a few hundred spoon-billed sandpipers are thought to remain, representing a severe decline from historical levels that were many times higher. Estimates have varied over the years, and the numbers cited by conservation organisations should be treated as approximate.
Research in the early twenty-first century revealed a rapid decline, with the breeding population falling sharply between the 2000s and the early 2010s. Surveys of breeding pairs in Russia showed small numbers, and counts in wintering areas also dropped. The species was assessed as Critically Endangered by the International Union for Conservation of Nature (IUCN) after earlier lower categories, reflecting the seriousness of the decline.
Some recent monitoring has suggested that the decline slowed or stabilised in certain years, partly credited to conservation action such as the head-start programme and hunting reduction. However, the population remains very small and vulnerable to chance events, so cautious optimism rather than confidence is the common expert view.
What threatens the spoon-billed sandpiper?
The main threats to the spoon-billed sandpiper are loss of intertidal mudflats through land reclamation and development, trapping and hunting on wintering grounds, disturbance, pollution and climate change. The bird’s long migration exposes it to dangers across many countries.
| Threat | Where it matters | Effect on the bird |
|---|---|---|
| Mudflat reclamation | Yellow Sea stopover sites in East Asia | Removes feeding and refuelling habitat during migration |
| Trapping and hunting | Wintering areas in parts of Southeast and South Asia | Kills adults, lowering survival |
| Disturbance | Wintering and breeding sites | Interrupts feeding and nesting |
| Pollution and aquaculture | Coastal wetlands | Degrades food supply and habitat quality |
| Climate change | Arctic breeding grounds and coastlines | Alters tundra habitat, predators and sea levels |
The relative importance of each threat is debated, though scientists broadly agree that the loss of stopover habitat in East Asia and hunting pressure on wintering grounds have been central. Natural predators such as foxes and gulls can also reduce breeding success, especially when numbers are low.
What is the flyway and why does it matter for India?
A flyway is the regular migration route used by a group of bird species between breeding and non-breeding areas, and the East Asian-Australasian Flyway is the route used by the spoon-billed sandpiper. It matters for India because Indian coastal wetlands are among the wintering destinations on the western edge of the route.
Flyway conservation requires cooperation between many governments, because a bird can be safe in one country and threatened in the next. The East Asian-Australasian Flyway Partnership brings together governments, non-governmental organisations and international bodies to protect a network of key sites. India also relates to the Central Asian Flyway through its own national action planning for migratory birds, though spoon-billed sandpipers are mostly associated with the East Asian route.
For India, the flyway approach means protecting wetlands as part of a larger system. A mudflat in Tamil Nadu or Odisha supports birds that also depend on mudflats in Myanmar and China. Strengthening monitoring and data-sharing across borders improves understanding of where the birds go and what they need.
What is being done to conserve the spoon-billed sandpiper?
Conservation of the spoon-billed sandpiper includes international coordination through the Spoon-billed Sandpiper Task Force, a head-start programme in Russia, hunting reduction in wintering countries, protection of key sites and community engagement. The Task Force brings together government agencies, scientists and organisations from the countries along the flyway.
- Head-start programme: Teams collect a limited number of eggs from nests in Chukotka, hatch and rear the chicks in protected conditions, and release them to fly on their own, improving early survival.
- Anti-trapping work: Community-based programmes, particularly in Myanmar and Bangladesh, support former hunters with alternative livelihoods and awareness materials.
- Site protection: Key wintering and staging areas have been recognised as protected areas or internationally important wetlands, including through the Ramsar Convention.
- Tracking and ringing: Coloured leg flags, geolocators and field surveys help reveal movements and survival.
- Captive populations: A small insurance population has been maintained in specialised facilities as a safeguard.
In India, the Bombay Natural History Society, state forest departments, local wildlife groups and researchers contribute through bird counts, ringing and habitat protection. Specific projects and results change over time, so current information should be checked from organisations active in the area.
How is the spoon-billed sandpiper protected under Indian law?
The spoon-billed sandpiper is protected in India under the Wildlife (Protection) Act, 1972, which prohibits hunting and trade in listed bird species and enables the creation of sanctuaries and national parks. The exact legal schedule of the species may change when the Act is amended, so the current text should be consulted.
Many Indian sites where the bird is recorded already enjoy legal protection. Point Calimere is a wildlife and bird sanctuary, the Gulf of Mannar includes a marine national park and biosphere reserve, and Chilika Lake is protected through its Ramsar designation and state management. India also participates in the Convention on the Conservation of Migratory Species of Wild Animals (CMS) as a party, which promotes cooperation on migratory species.
Law alone cannot guarantee protection. Effective management of coastal wetlands requires regulation of aquaculture, salt-pan operations, fishing and tourism, as well as control of pollution and disturbance. Community cooperation, especially with fishing communities, is a recurring theme in conservation recommendations.
What can people do to help the spoon-billed sandpiper?
People can help the spoon-billed sandpiper by supporting wetland protection, following responsible birdwatching practices, reporting sightings to recognised bird-monitoring programmes and backing organisations that work on flyway conservation. Small actions at the local level add up because the bird relies on a chain of sites.
Birdwatchers should keep a respectful distance from roosting and feeding flocks, avoid flushing birds, and share verified records through established platforms so that scientists can use the data. Coastal communities and local administrations can reduce plastic waste, limit disturbance and avoid reclamation of important mudflats.
Awareness is also essential. Because the bird is tiny and rarely seen, many people have never heard of it. Schools, nature clubs and media can highlight the connection between a small mudflat in India and a global conservation effort that spans the Arctic to the tropics.
Bottom Line
The spoon-billed sandpiper is a tiny, extraordinary migrant whose survival depends on protected mudflats from Russia to India. Indian sites such as Point Calimere, Chilika and the Gulf of Mannar form a small but meaningful part of that chain, and international cooperation remains vital.
Frequently Asked Questions
Why is the spoon-billed sandpiper critically endangered?
The spoon-billed sandpiper is critically endangered because its population has declined to a few hundred birds due to loss of intertidal mudflats, hunting and trapping on wintering grounds, and other pressures. The bird’s specialised habitat needs and long migration make it especially vulnerable.
Where can the spoon-billed sandpiper be seen in India?
The spoon-billed sandpiper in India has been recorded at Point Calimere in Tamil Nadu, Chilika Lake in Odisha and parts of the Gulf of Mannar, with occasional reports from other coastal wetlands. Sightings are rare and usually involve very few birds.
What is special about the bill of the spoon-billed sandpiper?
The bill of the spoon-billed sandpiper is flattened and widened at the tip into a spoon or spatula shape. The bird sweeps it side to side through soft mud to catch small invertebrates, which makes the species unique among shorebirds.
Where does the spoon-billed sandpiper breed?
The spoon-billed sandpiper breeds on the coastal Arctic tundra of far-eastern Russia, mainly in the Chukotka region. After breeding, it migrates thousands of kilometres south along the East Asian-Australasian Flyway to winter in South and Southeast Asia.
How many spoon-billed sandpipers are there?
Only a few hundred spoon-billed sandpipers are thought to remain, though estimates vary by source and survey year. The population has fallen sharply since the late twentieth century, and recent conservation measures are intended to prevent further decline.
What is the head-start programme for the spoon-billed sandpiper?
The head-start programme collects a limited number of eggs from nests in Russia, hatches and rears the chicks in protected conditions, and releases them as fledglings. This approach improves early survival and has been a key part of the international conservation effort led by the Spoon-billed Sandpiper Task Force.
