Bird Migrations in India: Routes, Seasons, Species, Best Birding Destinations & Conservation Guide

Introduction

Every year, millions of birds travel thousands of kilometres to reach India. Some arrive from the Arctic, Central Asia, Siberia, and parts of Europe, while others move shorter distances within the Himalayas or across the Indian subcontinent. These journeys are timed to coincide with changing seasons, food availability, and breeding cycles.

India plays a much larger role in this annual movement than many people realise. Rather than being just a winter destination, the country forms a crucial link in the Central Asian Flyway, one of the world’s major bird migration routes. Wetlands, floodplains, coastal mudflats, grasslands, reservoirs, and agricultural landscapes across India provide feeding grounds, resting sites, and wintering habitats for hundreds of migratory bird species. According to India’s National Action Plan for the Conservation of Migratory Birds and their Habitats, more than 370 migratory bird species visit the Indian subcontinent, with over 310 species depending primarily on wetlands during their journeys.

For birdwatchers, these seasonal arrivals transform many wetlands into some of the country’s best wildlife destinations. For conservationists, they demonstrate why protecting habitats across entire flyways—not just individual sanctuaries—is essential for the survival of migratory species.

Whether you are planning a winter birding trip, trying to identify birds visiting your local wetland, or simply curious about why birds travel such extraordinary distances, understanding migration helps explain one of nature’s most remarkable seasonal events.

What Is Bird Migration?

Bird migration is the regular seasonal movement of birds between different regions to take advantage of favourable weather, food supplies, and breeding conditions. Unlike random wandering, migration follows predictable routes that many species repeat every year.

Most birds migrate because the places where they breed become unsuitable during part of the year. In northern Asia and Europe, for example, lakes freeze, insects become scarce, and daylight hours shorten during winter. Many birds leave these areas and travel south to warmer regions where food remains available.

India serves as one of these seasonal destinations. Its relatively mild winters, extensive wetlands, long coastline, river systems, and diverse habitats allow migratory birds to feed and conserve energy before returning to their breeding grounds.

Migration is not limited to long-distance international journeys. Some birds move only between mountain elevations, while others shift regionally within India in response to seasonal rainfall or food availability. Understanding these different movement patterns is important because not every bird seen outside its usual range is a long-distance migrant.

Why India Is One of the World’s Most Important Countries for Migratory Birds

India’s importance extends beyond the number of birds that arrive each winter. Its geographical location places it at the heart of the Central Asian Flyway, one of the world’s nine recognised migratory bird flyways.

This flyway stretches across more than 30 countries, linking Arctic breeding grounds with wintering areas in South Asia, the Middle East, and the Indian Ocean region. Birds moving along this route depend on a connected network of wetlands, grasslands, lakes, coastal habitats, and floodplains to rest and refuel during their journeys.

India’s National Action Plan highlights that the country provides critical stopover sites for over 90% of the bird species known to use the Central Asian Flyway. This means habitats within India are not only important for birds that spend the winter here but also for many species that pause briefly before continuing their migrations to other destinations.

Another reason India is globally significant is its diversity of habitats. Migratory birds are not confined to famous bird sanctuaries. They also rely on:

• Freshwater lakes and marshes
• Ramsar wetlands
• Coastal mudflats and estuaries
• Mangroves
• River floodplains
• Reservoirs
• Grasslands
• Agricultural landscapes
• High-altitude Himalayan wetlands

Because these habitats are spread across the country, bird migration is a nationwide ecological phenomenon rather than something limited to a few protected areas.

Field Note: A single wetland rarely functions in isolation. Many migratory birds depend on a chain of stopover sites across multiple countries. If one important wetland is degraded, the effects can ripple throughout the entire migration route.

Comparison: Types of Birds Based on Seasonal Movement

India’s role in supporting each of these groups makes it one of Asia’s most important countries for bird migration and conservation.

Part 2 — The Central Asian Flyway, Migration Seasons & Types of Migratory Birds

The Central Asian Flyway Explained

Understanding the Central Asian Flyway (CAF) makes it much easier to appreciate why India is so important for migratory birds. Rather than viewing migration as birds simply flying from one country to another, the flyway concept recognises that migration depends on a connected network of habitats spread across an entire continent.

The Central Asian Flyway is one of the world’s nine major migratory bird flyways. It links breeding areas in northern Eurasia with wintering grounds across South Asia, West Asia and the Indian Ocean region, covering more than 30 countries. India lies near the southern end of this route, making it one of the last major wintering destinations for many species before they settle for the season.

Unlike birds that migrate along coastlines, many Central Asian Flyway species cross mountain ranges, rivers, grasslands, deserts and wetlands. Their survival depends on finding suitable places to rest and feed throughout this journey.

Why Stopover Sites Matter

A migratory bird rarely completes its journey in a single flight. Most species pause repeatedly at suitable habitats to replenish the energy needed for the next stage of migration.

These temporary resting areas are known as stopover sites.

An ideal stopover site offers:

• Abundant food
• Fresh water
• Safe resting areas
• Limited human disturbance
• Suitable weather conditions

Many Indian wetlands perform exactly this role. Even birds that eventually winter elsewhere may spend several days or weeks feeding in India’s lakes, floodplains or coastal mudflats before continuing south.

Because migration depends on an entire chain of habitats, conserving only breeding or wintering areas is not enough. The loss of even one important stopover site can reduce the survival of birds travelling thousands of kilometres.

Field Note: Think of migration like a long-distance road trip. A vehicle cannot complete the journey without fuel stations along the way. For migratory birds, wetlands are those fuel stations.

Why Wetlands Are So Important

Although migratory birds also use forests, grasslands and coastal habitats, wetlands play a particularly important role.

According to India’s National Action Plan for the Conservation of Migratory Birds, over 310 of the 370+ migratory bird species visiting the Indian subcontinent primarily depend on wetlands during migration or wintering.

Wetlands support large populations of:

• Fish
• Aquatic insects
• Molluscs
• Amphibians
• Crustaceans
• Aquatic vegetation

These food resources help birds recover after long flights and build the energy reserves needed for the next stage of migration.

The Action Plan also identifies 29 priority wetland sites and wetland clusters that act as important bottlenecks for migratory waterbirds, highlighting that protecting habitat networks is more effective than focusing on isolated sanctuaries alone.

Bird Migration Seasons in India

One of the most common misconceptions is that all migratory birds arrive in India at the same time. In reality, migration follows different schedules depending on species, weather patterns, breeding success and habitat conditions.

Autumn Arrival (August–November)

The migration season usually begins during late summer and autumn.

As temperatures start falling across northern Asia, many birds begin travelling south. The earliest arrivals are often shorebirds and some waterbirds that use India’s wetlands as stopover sites before continuing further.

By October and November, many winter visitors have reached their preferred habitats across the country.

Winter Peak (December–February)

For most birdwatchers, this is the best season.

During winter:

• Wetlands support thousands of ducks and geese.
• Shorebirds occupy mudflats and estuaries.
• Raptors become easier to observe in open habitats.
• Many cranes and large waterbirds gather at traditional wintering grounds.

This period generally offers the greatest diversity of migratory birds across much of India.

Spring Departure (March–April)

As temperatures begin rising in their northern breeding grounds, birds gradually leave India.

Departure does not happen simultaneously.

Some species begin returning north during February, while others remain until April depending on weather conditions and breeding schedules.

During this period, many wetlands become important staging grounds where birds feed intensively before undertaking their long northward journeys.

Why Arrival Dates Change Every Year

Migration timing is influenced by several natural factors.

These include:

• Weather patterns
• Water availability
• Food abundance
• Temperature
• Wind conditions
• Habitat quality

Recent observations from Indian wetlands suggest that some migration timings have become more variable, with delayed arrivals or altered distribution at certain sites. Researchers believe changing weather patterns, water levels and local disturbance all contribute to these shifts, although the extent varies between species and locations.

Photography Tip: For most wetlands, early morning offers the best combination of soft light, active bird behaviour and relatively calm conditions. Birds are often feeding actively soon after sunrise before temperatures increase.

Types of Migratory Birds Found in India

Not every bird that moves seasonally follows the same migration strategy. Recognising these categories helps birdwatchers better understand the behaviour and seasonal presence of different species.

Winter Visitors

These are the migratory birds most people encounter.

They breed in colder regions during summer before travelling south to spend winter in India.

Examples include:

• Bar-headed Goose (Anser indicus)
• Northern Pintail (Anas acuta)
• Black-tailed Godwit (Limosa limosa)
• Eurasian Curlew (Numenius arquata)

Most return to their breeding grounds during spring.

Passage Migrants

Passage migrants do not spend the entire winter in India.

Instead, they stop briefly while travelling between breeding and wintering grounds elsewhere.

These birds depend heavily on India’s wetlands for food and rest before continuing their journeys.

Several shorebirds, including species such as the Red Knot (Calidris canutus) and Curlew Sandpiper (Calidris ferruginea), may be observed as passage migrants at suitable wetlands and coastal habitats.

Altitudinal Migrants

Not all migration covers thousands of kilometres.

Some Himalayan birds simply move from higher elevations to lower valleys during winter, returning uphill when temperatures rise.

These shorter seasonal movements are known as altitudinal migration.

Although less dramatic than international migrations, they remain an important part of India’s seasonal bird movements.

Local and Partial Migrants

Some species move only short distances within India.

These movements may be triggered by:

• Rainfall
• Food availability
• Water levels
• Seasonal breeding

Unlike long-distance migrants, these birds may shift between neighbouring regions without crossing international borders.

Comparison: Types of Seasonal Bird Movement

Understanding these categories helps explain why some birds appear only briefly, while others remain throughout the winter.

Part 3 — Major Migratory Bird Groups & Best Places to See Them

Major Migratory Bird Groups Found in India

India hosts migratory birds from a wide range of ecological groups. While wetlands support the greatest diversity during winter, migrants also depend on coastal mudflats, grasslands, forests and agricultural landscapes. Understanding these groups helps birdwatchers know what to look for and where to find them.

Waterbirds

Waterbirds form the largest and most visible group of migratory birds visiting India. They include geese, ducks, swans, pelicans, storks, herons and other species that depend on lakes, marshes, reservoirs and floodplains.

Many arrive between October and November and remain until early spring.

Representative species include:

• Bar-headed Goose (Anser indicus) – Famous for crossing the Himalayas during migration.
• Northern Pintail (Anas acuta) – A graceful winter visitor to wetlands across northern and central India.
• Various migratory ducks that gather in large numbers at major lakes and reservoirs during winter.

These birds are among the easiest migrants to observe because they often congregate in open water.

Shorebirds

Shorebirds are generally smaller than ducks but undertake some of the longest migrations on Earth.

Most depend on:

• Coastal mudflats
• Estuaries
• Tidal creeks
• Marsh edges
• Seasonal wetlands

As water levels change, these habitats expose mud rich in worms, molluscs and small crustaceans.

Important examples include:

• Black-tailed Godwit (Limosa limosa)
• Curlew Sandpiper (Calidris ferruginea)
• Red Knot (Calidris canutus)
• Pacific Golden Plover (Pluvialis fulva)
• Great Knot (Calidris tenuirostris)
• Eurasian Curlew (Numenius arquata)

Many shorebirds use India as both a wintering destination and a stopover during migration.

Cranes

Cranes are among the most sought-after migratory birds because of their size and distinctive behaviour.

One of India’s best-known migratory cranes is the:

Black-necked Crane (Grus nigricollis)

This species winters in parts of the western Himalayas and is considered a high-priority species within India’s conservation planning.

Because cranes require relatively undisturbed wetlands and surrounding agricultural landscapes, they are particularly sensitive to habitat changes.

Raptors

Several birds of prey also migrate through or winter in India.

Unlike waterbirds, raptors rely on:

• Open grasslands
• Agricultural fields
• Forest edges
• Wetlands with abundant prey

Although they occur in lower numbers than ducks or shorebirds, winter is often an excellent season to observe migratory eagles, harriers and other birds of prey.

Landbirds

Migration is not limited to aquatic habitats.

Many small insect-eating and seed-eating birds migrate seasonally through forests, scrublands, orchards and farmlands.

These movements are often less noticeable than those of waterbirds because individual birds travel in smaller numbers and occupy a wider variety of habitats.

Representative Migratory Bird Species

Expert Tip: Don’t focus only on rare species. Large flocks of common migratory ducks, geese and waders often provide the best opportunities to study behaviour, feeding strategies and flock dynamics.

Best Places to See Migratory Birds in India

Choosing the right destination depends on the species you hope to see and the time of year you plan to travel. Some wetlands are famous for huge congregations of waterbirds, while others are better known for cranes, shorebirds or mixed wetland diversity.

Keoladeo National Park, Rajasthan

Keoladeo National Park (formerly Bharatpur Bird Sanctuary) remains one of India’s best-known birding destinations.

Its network of shallow wetlands attracts a wide variety of:

• Ducks
• Geese
• Herons
• Storks
• Pelicans
• Shorebirds

Because habitats are easily accessible by cycle, bicycle rickshaw or on foot, it is an excellent destination for both beginners and experienced birdwatchers.

Best suited for: First-time birdwatchers seeking high species diversity.

Chilika Lake, Odisha

Chilika Lake is India’s largest coastal lagoon and one of the country’s most important wintering grounds for migratory waterbirds.

Its mix of:

• Brackish water
• Mudflats
• Islands
• Marshes

supports enormous numbers of winter visitors every year.

Bird diversity changes across different sectors of the lagoon, making multiple visits worthwhile.

Best suited for: Waterbirds, ducks and coastal bird photography.

Pong Dam Lake, Himachal Pradesh

Located in the foothills of the Himalayas, Pong Dam Lake has become one of northern India’s most significant wintering wetlands.

Recent bird census reports continue to highlight its importance, while also showing that annual bird numbers may vary depending on water levels and seasonal conditions.

Best suited for: Geese, ducks and large wetland congregations.

Sultanpur National Park, Haryana

Situated close to Delhi, Sultanpur is one of India’s most accessible birdwatching destinations.

Recent observations suggest that migration timing and bird distribution can vary from year to year due to changing water conditions and weather patterns, demonstrating why repeated monitoring remains important.

Best suited for: Day trips and winter bird photography.

Deepor Beel, Assam

Deepor Beel is an internationally recognised wetland supporting numerous resident and migratory birds.

Its shallow waters and surrounding marshes make it an important seasonal refuge for waterbirds travelling along the Central Asian Flyway.

Loktak Lake, Manipur

Known for its floating vegetation, Loktak Lake provides habitat for both resident and migratory birds.

Its varied wetland habitats support different bird communities throughout the migration season.

Wular Wetlands, Jammu & Kashmir

One of India’s largest freshwater lakes, Wular serves as an important northern stopover and wintering site for numerous migratory waterbirds.

Its location within the Himalayan region makes it particularly significant for species moving south from Central Asia.

Point Calimere, Tamil Nadu

Point Calimere combines coastal wetlands, mudflats and salt pans, making it especially valuable for shorebirds and coastal migrants.

Many passage migrants use the area while travelling along coastal migration routes.

Kaziranga Wetland Complex, Assam

Although famous for its one-horned rhinoceroses, Kaziranga also contains extensive wetlands that attract numerous migratory birds during winter.

Visitors interested in both mammals and birds often find it an excellent multi-species destination.

Gharana Wetlands, Jammu

Located near the international border, Gharana Wetlands provide valuable habitat for migratory waterbirds and demonstrate how even relatively small wetlands can play an important role within a much larger flyway network.

Comparison of Major Birding Destinations

Photography Tip: Visit wetlands soon after sunrise or during the final two hours before sunset. Besides softer light, birds are usually more active, and calmer wind conditions often improve reflections on the water.

Part 4 — Threats, Conservation, Recent Developments & Responsible Birdwatching

Threats Facing Migratory Birds in India

Migratory birds depend on a chain of healthy habitats spread across thousands of kilometres. As a result, even small changes at multiple locations can have a cumulative effect on their survival.

India’s National Action Plan identifies habitat degradation, wetland loss and increasing human pressures as major challenges for migratory birds using the Central Asian Flyway. Rather than acting in isolation, these threats often reinforce one another.

Wetland Loss and Habitat Fragmentation

Wetlands are among the most productive ecosystems used by migratory birds, yet many are under pressure from:

• Urban expansion
• Land reclamation
• Pollution
• Encroachment
• Unsustainable development

When wetlands shrink or become fragmented, birds lose places to feed and rest during migration. Even if breeding and wintering grounds remain intact, the loss of stopover sites can reduce migration success.

Changes in Water Management

Many important bird habitats depend on seasonal flooding and natural water levels.

Altered river flows, drainage, excessive water extraction and poorly timed reservoir management can affect:

• Food availability
• Nesting habitat
• Mudflat exposure
• Wetland vegetation

Recent observations from several Indian wetlands show that annual bird numbers often vary with water conditions, highlighting the close relationship between hydrology and migration.

Climate Change

Climate influences migration in several ways.

Changing temperatures may affect:

• Departure dates
• Arrival timing
• Food availability
• Wetland water levels
• Breeding success

Recent reports from Indian wetlands have noted delayed arrivals and altered migration timing for some species. However, these changes are not uniform across all birds or locations, and researchers continue to study long-term trends.

Hunting and Human Disturbance

Repeated disturbance can force birds to abandon otherwise suitable habitats.

Common sources include:

• Unregulated tourism
• Boating
• Off-road vehicles
• Illegal hunting
• Free-ranging dogs
• Frequent human activity near feeding areas

Migratory birds need long periods of uninterrupted feeding to rebuild energy reserves. Disturbance reduces the time available for feeding and increases energy expenditure.

Power Lines, Electrocution and Light Pollution

The National Action Plan also highlights threats that receive less public attention but can significantly affect migratory birds.

These include:

• Collisions with overhead power lines
• Electrocution
• Artificial night lighting
• Expanding infrastructure near migration routes

Large birds such as cranes and waterbirds are particularly vulnerable because of their size and flight behaviour.

Comparison: Major Threats to Migratory Birds

Field Note: A wetland may appear healthy because large numbers of birds are present one year. That does not necessarily indicate a stable population. Birds often shift between nearby wetlands depending on rainfall, water depth and local disturbance.

How India Conserves Migratory Birds

Protecting migratory birds requires cooperation across countries because these species cross international borders during their annual journeys.

India’s conservation efforts combine habitat protection, scientific monitoring, international cooperation and community participation.

National Action Plan for the Central Asian Flyway

In 2018, India launched the National Action Plan for Conservation of Migratory Birds and their Habitats along the Central Asian Flyway.

The plan aims to:

• Conserve migratory bird populations.
• Protect important habitats.
• Improve scientific monitoring.
• Strengthen international cooperation.
• Encourage research.
• Increase public awareness and community participation.

Its long-term objective is to arrest population declines while securing habitats throughout the flyway.

Organisations Involved

Conservation depends on collaboration between multiple organisations.

Key participants include:

• Ministry of Environment, Forest and Climate Change (MoEFCC)
• Wildlife Institute of India (WII)
• Bombay Natural History Society (BNHS)
• Wetlands International South Asia
• State Forest Departments
• Local communities
• International conservation partners

Each organisation contributes through research, habitat management, monitoring or policy implementation.

Citizen Science and the Asian Waterbird Census

Professional surveys alone cannot monitor every wetland across India.

Citizen science programmes therefore play an increasingly important role.

One of the best-known initiatives is the Asian Waterbird Census, where trained volunteers and birdwatchers help record waterbird numbers at wetlands across the country.

These observations help researchers:

• Monitor long-term population trends.
• Detect changes in migration timing.
• Identify emerging conservation issues.
• Prioritise important wetlands for protection.

The research brief also highlights citizen science as an area frequently overlooked by competing articles despite its importance for conservation.

Expert Tip: If you regularly visit a local wetland, consider participating in organised bird counts through recognised conservation groups. Consistent observations collected over many years are often more valuable than isolated records.

Recent Developments

Bird migration research continues to evolve as new monitoring data becomes available.

Some notable developments highlighted in the research brief include:

• 2024: The Convention on Migratory Species (CMS) COP14 adopted an initiative supporting stronger cooperation across the Central Asian Flyway, encouraging coordinated conservation among participating countries.
• 2025: Bird census reports from wetlands including Pong Dam and regions of Punjab and Kashmir highlighted both encouraging counts at some sites and changing arrival patterns linked to water availability and seasonal conditions.
• 2026: Reporting from Sultanpur National Park suggested delayed migration patterns and birds dispersing across different habitats, reinforcing the importance of long-term monitoring rather than relying on observations from a single season.

These examples illustrate an important point: migration is dynamic. Annual bird numbers naturally fluctuate, and interpreting changes requires careful analysis over multiple years.

Responsible Birdwatching During Migration

Watching migratory birds responsibly helps ensure that future visitors can enjoy the same natural spectacle without causing unnecessary disturbance.

Practical Checklist

✔ Stay on designated trails wherever possible.

✔ Use binoculars or telephoto lenses instead of approaching birds closely.

✔ Maintain a respectful distance from feeding and resting flocks.

✔ Keep noise to a minimum.

✔ Avoid using recorded bird calls unless specifically permitted for research.

✔ Never chase birds for photographs.

✔ Leave no litter behind.

✔ Respect temporary access restrictions during sensitive periods.

Photography Tip

Good wildlife photographs depend more on patience than proximity.

Instead of approaching birds, remain still and allow them to behave naturally. This usually results in more authentic images while reducing disturbance.

Family Travel Tip

Children often enjoy birdwatching more when they focus on observing behaviour rather than identifying every species. Encourage them to notice feeding methods, flight formations and interactions between different birds.

Responsible Tourism Tip

Many migratory birds have already travelled thousands of kilometres before reaching India. Disturbing feeding flocks may force them to waste valuable energy reserves needed for the next stage of migration. Observing quietly from a distance benefits both birds and visitors.

End of Part 4.

Part 5 — Common Mistakes, Frequently Asked Questions & Conclusion

Common Mistakes People Make When Learning About Bird Migration

Bird migration is often simplified, leading to several misconceptions. Understanding these helps birdwatchers interpret what they see more accurately and appreciate the conservation challenges involved.

Mistake 1: Assuming All Migratory Birds Arrive at the Same Time

Different species migrate according to their own schedules.

Some begin arriving in August, many reach India during October and November, while others pass through only briefly or depart earlier than expected.

Weather, water levels and food availability can also influence annual arrival dates.

Mistake 2: Thinking Migration Is Only a Winter Phenomenon

Winter migration is the most visible, but it is only one part of the annual cycle.

Birds also migrate:

• To breed.
• During spring return journeys.
• Between different elevations.
• In response to seasonal food availability.

Migration is therefore a year-round ecological process rather than a single seasonal event.

Mistake 3: Believing Only Wetlands Matter

Wetlands are extremely important, but they are not the only habitats used by migratory birds.

Many species also depend on:

• Grasslands
• Agricultural landscapes
• Coastal mudflats
• Forests
• River systems
• High-altitude lakes

Conserving the full range of habitats is essential for protecting migratory birds throughout their journeys.

Mistake 4: Assuming One Bird Sanctuary Can Protect an Entire Species

Migratory birds cross multiple countries and depend on many different habitats during their annual journeys.

A single sanctuary may protect birds for only a few weeks each year.

Long-term conservation depends on maintaining an interconnected network of healthy habitats across the entire flyway.

Mistake 5: Judging Population Trends from a Single Visit

Seeing large numbers of birds at one wetland does not necessarily mean populations are increasing.

Birds frequently shift between nearby wetlands in response to:

• Water levels
• Rainfall
• Disturbance
• Food availability

For this reason, scientists rely on repeated surveys over many years rather than isolated observations.

Frequently Asked Questions

What is bird migration?

Bird migration is the regular seasonal movement of birds between breeding, wintering and stopover areas in response to changing weather, food availability and breeding requirements.

Why do migratory birds come to India?

India offers relatively mild winter conditions and a wide variety of habitats, including wetlands, floodplains, grasslands, coastal mudflats and reservoirs that provide food and shelter during migration.

What is the Central Asian Flyway?

The Central Asian Flyway is one of the world’s nine major migratory bird flyways. It connects breeding areas in northern Eurasia with wintering grounds across South Asia and includes more than 30 countries. India is one of its most important stopover and wintering regions.

How many migratory bird species visit India?

According to India’s National Action Plan for the Conservation of Migratory Birds, more than 370 migratory bird species visit the Indian subcontinent, and over 310 of them primarily depend on wetlands.

Which months are best for watching migratory birds in India?

For most destinations, November to February offers the greatest diversity of migratory birds. However, exact timing varies between species and locations.

Which places are best for bird migration in India?

Some of the country’s most important migration destinations include:

• Keoladeo National Park
• Chilika Lake
• Pong Dam Lake
• Sultanpur National Park
• Deepor Beel
• Loktak Lake
• Wular Wetlands
• Point Calimere
• Kaziranga Wetland Complex
• Gharana Wetlands

Are all migratory birds waterbirds?

No. While many migrants depend on wetlands, India also hosts migratory shorebirds, raptors, cranes and numerous landbirds that use forests, grasslands and agricultural landscapes.

What is a passage migrant?

A passage migrant stops in India temporarily while travelling between breeding and wintering grounds elsewhere. Unlike winter visitors, these birds do not remain throughout the season.

Why are wetlands so important?

Wetlands provide food, fresh water and safe resting areas during migration. Many species cannot complete their journeys without these stopover habitats.

How does climate change affect bird migration?

Research suggests that changing temperatures, rainfall patterns and water availability may influence migration timing and habitat use. However, these effects vary between species and locations, and long-term monitoring remains essential.

What is the Asian Waterbird Census?

The Asian Waterbird Census is a long-running monitoring programme in which trained volunteers and experts count waterbirds at wetlands across Asia. These surveys help scientists track population trends and identify important conservation sites.

Can ordinary birdwatchers contribute to conservation?

Yes. Reporting bird sightings through recognised citizen science initiatives, participating in organised bird counts and practising responsible birdwatching all contribute valuable information for conservation.

Are migratory birds protected in India?

Yes. India supports migratory bird conservation through wildlife protection laws, protected areas, international agreements and the National Action Plan for the Conservation of Migratory Birds and their Habitats along the Central Asian Flyway.

Conclusion

Bird migration is one of the most remarkable natural events witnessed across India each year. From high-altitude Himalayan lakes and inland reservoirs to coastal mudflats and vast wetlands, the country supports hundreds of migratory bird species that travel thousands of kilometres along the Central Asian Flyway.

These seasonal visitors are more than just an attraction for birdwatchers. Their journeys reflect the health of interconnected ecosystems that extend across continents. Protecting a single sanctuary is valuable, but conserving migratory birds ultimately requires healthy wetlands, grasslands, rivers and coastal habitats throughout the entire flyway.

For travellers, understanding migration adds a new dimension to wildlife experiences. A visit to a wetland in winter becomes more meaningful when you realise that many of the birds feeding quietly before you have crossed mountains, deserts and international borders to reach India.

Whether you are planning your first birdwatching trip or have years of field experience, observing migratory birds responsibly helps ensure that these remarkable journeys continue for generations to come.
