Kanwar Lake Bird Sanctuary, also known as Kabartal, is Bihar’s hidden gem for nature enthusiasts and birdwatchers. Located in Begusarai district, this wetland is the largest freshwater oxbow lake in Asia, covering over 67.5 km². It is a crucial stopover along the Central Asian Flyway, hosting more than 220 bird species, including 58 migratory birds such as the critically endangered White-rumped Vulture and endangered Sociable Lapwing.

Visiting Kanwar Lake Bird Sanctuary felt like stepping into a peaceful world far away from city noise. The serene views of the lake, the quiet marshes, and the lush greenery instantly slowed everything down. As I walked along the wetlands, I spotted several rare and migratory birds in their natural habitat—moments that were perfect for photography and simple nature watching. The calmness of the place and the soft sounds of the birds made the whole experience unforgettable.

What impressed me even more was learning how important this lake is for the region. It helps recharge groundwater, supports local farming, and is home to more than 50 freshwater fish species. No wonder Kanwar Lake was declared Bihar’s first Ramsar site in 2020—a well-deserved recognition for a wetland of global ecological importance.

I visited during the migratory season, between October and March, and that’s truly the best time to experience the sanctuary. The lake becomes alive with colorful birds, and every turn on the trail offers something new to admire.

Reaching the sanctuary is easy—whether you come by road, rail, or air—which makes it suitable for both a short day trip or a slow, relaxing nature getaway. Its mix of rich biodiversity, scenic beauty, and complete tranquility makes it one of those places in Bihar you must visit at least once.

If you love bird watching, photography, or just being close to nature, Kanwar Lake Bird Sanctuary will leave you with memories you’ll want to revisit again and again. My time there reminded me how important these ecosystems are—not just for wildlife, but also for local communities and for anyone seeking a peaceful connection with nature.

Kanwar Lake:

For me, the real highlight of the sanctuary was Kanwar Lake—Asia’s largest freshwater oxbow lake. Standing beside it, I was honestly amazed by how vast and calm it looked. This huge stretch of water becomes a lifeline for thousands of migratory birds, and watching them arrive and settle across the lake was one of the most peaceful experiences of my trip.

The lake is surrounded by lush vegetation and aquatic plants, which makes the whole area feel untouched and beautifully natural. As I walked around, I kept noticing how alive the ecosystem is—fish darting in the water, amphibians along the edges, and so many unique plant species adding to the sanctuary’s charm.

If you visit, I highly recommend taking a boat ride. Floating across the lake gives you a completely different perspective—you get even closer to the birds, and the calmness of the water feels almost therapeutic. Even if you don’t get on a boat, simply sitting by the shore and taking in the scenery is enough to make you feel connected to this incredible wetland paradise.

Avian Diversity:

When I visited Kanwar Lake Bird Sanctuary, it felt like the whole place had come alive in a burst of wings and colors. Everywhere I looked, there was movement—graceful birds taking flight, splashes in the shallows, and calls echoing across the wetlands. It’s easy to see why bird lovers from all over are drawn here; the diversity is unbelievable.

The sanctuary is a true refuge for both migratory and resident birds. I remember watching elegant cranes glide across the sky while storks stood tall nearby, and herons quietly searched for food along the water’s edge. The ducks were the most eye-catching—bright, colorful, and constantly on the move, painting the lake with their vibrant presence.

I went during winter, and that’s when the sanctuary really transforms. The number of migratory birds increases so much that it almost feels like you’ve stepped into a huge, bustling bird city. I spent hours just observing them—each species with its own behavior, calls, and charm.

Birdwatching Towers:

One of the things I loved most about Kanwar Lake Bird Sanctuary was the series of sturdy birdwatching towers scattered across the landscape. Standing on these elevated platforms felt like stepping into a different world. From the top, I could see the entire lake stretching out in front of me, along with the marshes and all the hidden corners where the birds gather.

Looking down from the tower, I watched some birds foraging quietly in the shallow waters while others traced smooth, graceful arcs across the sky. The view made me feel completely immersed in the sanctuary—almost as if I was part of the ecosystem for a moment. These towers truly enhance the whole experience, giving you a deeper connection to nature and a front-row seat to the behaviour of the birds in their natural habitat.

Boating:

One of my favorite moments at Kanwar Lake was taking a slow, peaceful boat ride across its glassy surface. As the boat drifted forward, the calmness of the lake instantly relaxed me. The shores were lined with tall reeds and lush greenery, making the whole scene feel untouched and incredibly serene. I kept scanning the edges of the lake, and every few minutes, a new bird appeared—some perched proudly on the reeds, others taking flight right above me. Being out on the water gave me a completely different perspective of the sanctuary. It was the perfect way to enjoy birdwatching up close and capture some truly memorable moments.

Why Kanwar Lake Matters

My Insights on the Unique Geography & Hydrology

During my visit, I was fascinated to learn that Kanwar Lake is actually a residual oxbow lake, shaped over centuries by the winding path of the Burhi Gandak River, which itself is a tributary of the Ganga. Walking around the area, I could clearly see how the landscape changes with the seasons. Locals told me that during the monsoon, the lake swells up to about 1.5 meters deep, while in the dry months, many sections shrink or dry out completely.

What struck me most was how important this lake is for the region. It acts as a natural flood control system, absorbing excess water from the surrounding plains. The entire sanctuary covers nearly 2,620 hectares of wetland, forming part of a much larger floodplain ecosystem. Seeing it in person helped me understand how such wetlands quietly protect both wildlife and nearby communities.

Biodiversity & Wildlife: What I Observed and Learned

The sanctuary is incredibly rich in life. According to official records—and from what I experienced firsthand—Kanwar Lake supports over 165 plant species and nearly 394 animal species. But the real highlight is the birdlife. An impressive 221 species of birds have been recorded here, both resident and migratory.

I even got the chance to spot some of the critically endangered vultures the area is known for, including the red-headed vulture, white-rumped vulture, and Indian vulture. Learning that these rare species still survive here gave me a new appreciation for the sanctuary’s importance.

Kanwar Lake is also a major stopover for migratory birds traveling along the Central Asian Flyway. Birdwatchers often talk about the sightings of rare waterbirds like the sociable lapwing and Baer’s pochard, and hearing those stories made me even more excited about what this region holds.

Conservation Challenges: What’s Really Happening

While the sanctuary is breathtaking, it’s also clear that Kanwar Lake is facing serious challenges. Locals and conservation volunteers shared how large sections of the lake dry up during harsh summers, which has contributed to a decline in bird numbers over the years.

The more I asked around, the more concerns I heard:

• Encroachment into wetland areas
• Siltation reducing water depth
• Excessive water extraction
• Damaged or blocked natural water channels

These issues threaten the lake’s long-term survival. What’s disappointing is that experts have been pushing for an Ecological Restoration Plan for years, but as of 2025, it still hasn’t been implemented. Seeing the lake’s beauty alongside its struggles makes you realize how urgently this ecosystem needs protection.

What Makes Kanwar Lake Special

• Threatened Species: Some critically endangered species live there, such as several vulture species (red-headed vulture, Indian vulture, white-rumped vulture), Baer’s pochard, and sociable lapwing.
• Size & Type: It’s Asia’s largest freshwater oxbow lake. It spans around 2,620 hectares in the Indo-Gangetic plains.
• Ecological Importance: The lake floods during monsoon (up to ~1.5 m depth), which helps with flood control for nearby areas. During dry seasons, some areas turn marshy or are used for agriculture.
• Biodiversity: There are around 165 plant species and 394 animal species, including 221 bird species. Over 50 fish species have been recorded. It is also on the Central Asian Flyway, serving as a rest stop for many migratory waterbirds.

Local Experiences at Kanwar Lake Bird Sanctuary

Unwinding on tranquil waters:
One of the most peaceful things I did here was glide across Kanwar Lake on a slow boat ride. The stillness of the water and the wide, open views of the wetlands instantly calmed me. I kept spotting birds along the shoreline—some taking flight right next to the boat, others perched quietly in the reeds.

Exploring hidden corners:
I also spent time walking through the sanctuary’s nature trails, which are well-marked and easy to follow. Each path took me through different habitats, all buzzing with life. I saw colorful butterflies, plenty of bird species, and even a couple of small mammals peeking out from the bushes. The informative boards along the trail helped me understand the ecological story of the place.

Climbing for the best views:
The birdwatching towers were another highlight. I climbed a few of them, and the panoramic views from the top were incredible. Watching birds move across the landscape from that height gave me a whole new appreciation for how they interact with the wetland.

Capturing memories:
If you love photography, this place is a goldmine. Everywhere I turned, there was something worth capturing—unique birds, lush greenery, reflections on the water, and the peaceful charm of the wetlands. I left with so many shots I’m proud of.

Learning more about the ecosystem:
I also visited the interpretation center, where I learned about the sanctuary’s diverse birdlife and why wetlands like Kanwar Lake are so important. It added a lot of depth to my overall experience.

Spotting more than just birds:
Beyond the birdlife, I kept an eye out for turtles, frogs, and other small creatures that call this sanctuary home. It’s amazing how much life thrives here once you start noticing the small details.

Connecting with the locals:
During my visit, I got a chance to talk to a few people from the nearby villages. Hearing about their traditional lifestyle and their connection to the lake made my trip feel even more meaningful.

Enjoying local flavors:
After exploring, I stopped by a small eatery near the sanctuary and tried some regional dishes. The food was simple, fresh, and absolutely delicious—perfect after a long day outdoors.

Giving back:
If you’re interested, the sanctuary often has eco-friendly activities like clean-up drives or tree-planting programs. Joining one is a great way to support conservation efforts. I found it genuinely fulfilling.

Joining guided activities:
There are also birdwatching competitions and guided tours organized by local conservation groups. Participating in one added a fun, educational touch to my visit and helped me sharpen my bird-spotting skills.
