November Visitors: The Migratory Birds That Find a Winter Home in and Around Bengaluru

 

Every winter, birds travel incredible distances in search of food, suitable weather and safe places to rest. As November brings more winter visitors to southern India, Bengaluru’s lakes, wetlands and green spaces become important places to pause, feed and recover. But how welcoming is our rapidly changing city to these seasonal travellers?

There is something remarkable about looking up at a bird crossing the sky and realising that it may have travelled hundreds, or even thousands, of kilometres to reach here.

For many birds, November marks an important phase of the annual migration season. As temperatures fall in parts of northern India and beyond, migratory species begin arriving in more favourable regions, including southern India. Some travel across countries and ecological landscapes, while others make shorter seasonal journeys within the subcontinent.

Bengaluru, with its network of lakes, wetlands, wooded areas and open spaces, can offer valuable habitat to some of these visitors.

But what brings them here, and what does it take for them to complete their journeys safely?

Why Do Birds Migrate?

Migration is one of nature’s most extraordinary survival strategies. Birds move between regions in response to changing temperatures, food availability, breeding conditions and the need for suitable habitats.

For many migratory species, the journey begins when conditions in their breeding grounds become less favourable. Food may become scarce, water bodies may freeze, or colder weather may make survival more difficult. Travelling to warmer regions allows these birds to access the resources they need during the winter months.

India lies along several important migratory routes, making it a seasonal destination for birds from different parts of the world. Depending on the species, birds may travel from Central Asia, Europe, Siberia and other regions, while others move within India in response to seasonal changes.

Migration, however, is not simply a journey from one destination to another. It is a series of demanding stages involving flight, navigation, feeding and rest. Birds must find suitable places to replenish their energy before continuing their journeys or settling into their winter habitats.

For some, a lake or wetland in and around Bengaluru may provide just such a refuge.

Bengaluru’s Lakes: More Than Urban Landmarks

Bengaluru’s lakes are often valued for their role in water management, recreation and the city’s landscape. Yet they are also living ecosystems that support a wide variety of wildlife.

During the migration season, suitable lakes and wetlands can attract waterbirds seeking food and resting areas. Depending on the habitat and prevailing conditions, these may include ducks, waders and other migratory waterbirds.

Shallow waters, muddy edges, aquatic vegetation and the small organisms living within them can provide important feeding opportunities. Nearby trees and quieter stretches of habitat may offer places to rest.

Not every lake attracts the same species, and bird numbers can vary from year to year. Water quality, water levels, vegetation and disturbance all influence how useful a wetland is to visiting birds.

This is why protecting Bengaluru’s lakes is about more than preserving open water. It is about maintaining the complex habitats that allow birds and other wildlife to survive.

The Challenges Along the Journey

Migration is demanding even under natural conditions. Birds must navigate unfamiliar landscapes, manage their energy reserves and locate food and shelter along the way.

Human activity can make this journey considerably harder.

Habitat loss: Wetlands, grasslands and wooded areas provide essential feeding and resting sites. When these habitats are degraded, polluted or built over, birds lose places they depend on during migration.

Glass collisions: Reflective and transparent glass can be difficult for birds to recognise as a barrier. Trees and sky reflected on building façades may appear to offer a clear flight path, increasing the risk of collisions.

Pollution: Contaminated water and the degradation of aquatic ecosystems can reduce food availability and make wetlands less suitable for wildlife.

Disturbance: Loud activity, approaching too closely, chasing birds for photographs and repeatedly disturbing resting or feeding flocks can cause birds to expend energy they need for survival.

Changing environmental conditions: Changes in rainfall, temperatures and the availability of water and food can influence migration timing and the suitability of habitats along a bird’s route.

For a bird that has already travelled a considerable distance, losing access to a safe resting place can have serious consequences.

Not Every Bird You See Is a Migrant

Migration season is also a wonderful opportunity to appreciate Bengaluru’s resident birds.

Species such as the rose-ringed parakeet, common myna and red-whiskered bulbul live in the city throughout the year. They share the urban landscape with seasonal visitors, each relying on different resources and habitats.

Learning to recognise the difference can make birdwatching more rewarding. A bird that appears unfamiliar may be a seasonal visitor, but it could also be a resident species that is less commonly seen in your neighbourhood.

The best way to learn is to observe carefully, use a reliable field guide or bird identification resource, and record sightings without disturbing the birds.

You do not need to be an expert to begin noticing the changes that take place in Bengaluru’s birdlife between November and the months that follow.

How Can We Make Bengaluru Safer for Migratory Birds?

Protecting migratory birds does not begin and end in distant forests or wetlands. Our neighbourhoods, buildings and everyday choices matter too.

Here are a few ways to help:

• Protect lakes and wetlands. Support efforts to conserve natural water bodies, improve water quality and preserve their surrounding vegetation.

• Make buildings bird-safe. Encourage bird-friendly building design and appropriate measures to reduce collisions with glass.

• Keep your distance. Observe birds quietly, use binoculars where possible and avoid approaching resting or feeding flocks.

• Keep habitats clean. Dispose of waste responsibly and never leave plastic, fishing line or other entangling materials in natural spaces.

• Preserve trees and native vegetation. These provide shelter, nesting opportunities and food for resident birds and other wildlife.

• Record sightings responsibly. Sharing observations with local birdwatching groups and citizen-science initiatives can help improve our understanding of seasonal bird movements.

If you encounter an injured bird, avoid handling it unnecessarily. Keep people and pets away, and contact a qualified wildlife rescue organisation for guidance.

A Seasonal Visitor, A Shared Responsibility

The arrival of migratory birds is a reminder that wildlife does not recognise the boundaries we draw around cities, states or countries. A bird resting on a Bengaluru lake may have crossed vast landscapes to reach it, depending on a chain of habitats along the way.

Its journey connects ecosystems that may appear distant from one another, demonstrating just how closely the natural world is linked.

As November progresses, take a little time to visit a nearby lake or green space. Watch the water's edge, listen to the calls around you and notice which birds are sharing the landscape.

And remember that the best way to welcome these seasonal visitors is not to get closer, but to ensure that they have the space, food and safe habitats they need.

At PfA Wildlife Hospital, Bengaluru, we believe that protecting wildlife also means protecting the habitats that sustain it. This migration season, let us make Bengaluru a safer place for the birds that travel so far to spend the winter here.
