Barju Lake: A Birdwatcher's Haven in Eastern Nepal
Geographic & Biogeographic Location: Barju Lake—also known as Chimdi Taal—is a serene wetland located in Barju Rural Municipality, Sunsari District, in Koshi Province, eastern Nepal. It lies approximately 12 km northwest of Biratnagar, near the Indian border, making it easily accessible to both domestic and international visitors. The lake sits at an elevation of around 80 meters above sea level and an important ecological corridor for migratory birds.
Habitat & Vegetation: Barju Lake spans 152 bighas (roughly 250 acres), though only about a quarter of this area is open water. The rest comprises marshlands, reed beds, lotus-covered shallows, and seasonally flooded farmlands. The lake supports a mosaic of aquatic and semi-aquatic vegetation, including:
- Pink Lotus (Nelumbo nucifera)**
- Water hyacinth
- Reeds and sedges
- Riparian shrubs and grasses
This diverse habitat provides ideal nesting, feeding, and roosting grounds for a wide range of bird species.
Typical Bird Species & Bird Communities: Barju Lake is a hotspot for resident and migratory birds, with over 200 species recorded, including more than 100 migratory species. Bird communities here range from wetland specialists to forest-edge dwellers and open-country species.
Key species include:
- Asian Openbill Stork
- Purple Heron
- Oriental Darter
- Black-headed Ibis
- Lesser Whistling Duck
- Bronze-winged Jacana
- Common Kingfisher
- Indian Pond Heron
- Red-wattled Lapwing
- White-breasted Waterhen
During winter (Nov–Feb), the lake becomes a sanctuary for migratory waterfowl, including Gadwalls, Teals, and Pochards, making it a prime birdwatching destination.
Land Use & History: Historically, Barju Lake has deep cultural roots, with mentions in the Mahabharata as a resting place for the Pandavas during their exile. Traditionally used for fishing and irrigation, the lake has seen increasing pressure from encroachment and overfishing, leading to habitat degradation. However, since the 2012 conservation initiative led by the local community, bird populations have rebounded, and the lake is now recognized as a major bird sanctuary in eastern Nepal.
Importance for Birdwatching: Barju Lake is considered the second-best birding site in eastern Nepal, after Koshi Tappu. Its strategic location along migratory flyways, combined with diverse habitats and low human disturbance (especially on weekdays), makes it ideal for:
- Casual birdwatchers
- Professional ornithologists
- Eco-tourists
- Photographers
