Survey at Arunachal's Nongsaya Lake records 89 bird species

A two-day survey held at a lake in Arunachal Pradesh's Namsai documented 89 bird species, officials said on July 10.

The survey was carried out at the Nongsaya Lake in Jona, around 9 km from Namsai town, by the Arunachal Pradesh Birding Club (APBC) in collaboration with the Public Works Department, conservationist Koj Mama said.

“The survey was undertaken recognising the critical ecological role the lake plays,” he said.

Key bird species spotted during the survey included oriental darter, lesser adjutant, pale-chinned blue flycatcher, blossom-headed parakeet, yellow-bellied warbler and chestnut-capped babbler.

“The lake and its surrounding forested environment offer rich biodiversity, with immense potential for bird and butterfly conservation. In addition to acting as a natural habitat, the area could serve as an ideal location for environmental education and recreational activities,” Mama said.

Highlighting the ecological significance of the lake, he stated that the area could contribute meaningfully to sustainable development and community engagement in ecosystem protection.

The team also recorded several butterfly species, including the rare Assam Pasa, underlining the area’s ecological richness, he said.

With its lush green forest cover and potential as a sanctuary for migratory water birds, Nongsaya Lake holds promise as a future global bird-watching destination, the conservationist said.

Mama stressed that the creation of suitable infrastructure, particularly carefully designed trekking routes that avoid disturbing wildlife, could open the area to responsible ecotourism.

He emphasised that the lake’s ecosystem plays a crucial role in preserving major watersheds and sustaining biodiversity.

“With a proper development strategy, the lake can serve multiple purposes, such as conservation, sustainable fishing, recreation, and as a sanctuary for migratory birds,” Mama added.

Migratory birds, in particular, play a vital role in maintaining ecological balance, serving as indicators of environmental health and aiding in long-term conservation planning.

Mama believes that the development of Nongsaya Lake as a green biodiversity zone could substantially enhance both environmental and economic sustainability in Namsai district.
