Kaziranga, a UNESCO World Heritage Site recognized for its rich biodiversity for over 119 years, is home to the Big Five mammals and over 500 bird species. It features two Important Bird Areas, Kaziranga National Park and Laokhowa and Burhachapori Wildlife Sanctuaries, vital for both migratory and resident waterbirds. The waterbird census, initiated in 2018-19 and supported by Numaligarh Refinery Limited’s CSR program, has become a significant citizen science movement, involving ornithologists, students, and volunteers. The 2026 survey conducted from January 4 to 11 covered 166 wetlands across several wildlife divisions, documenting 105,540 waterbirds of 107 species. Notable findings included high concentrations of Bar-headed Goose and Northern Pintail. Conservation concerns were raised, including one critically endangered, one endangered, two vulnerable, and fourteen near-threatened species per the IUCN Red List.
Rowmari Beel recorded the highest bird congregation with 15,661 individuals and the most species diversity. The survey’s highlight was the sighting of the Smew, a rare winter migrant duck, indicating wetland health and potential climate-related shifts in migration. The report, released on February 22, 2026, emphasized the need for protecting crucial habitats amid threats like hunting and pollution, with strong endorsements from government and conservation leaders. The findings serve as a baseline for wetland health assessment and necessitate comprehensive conservation strategies amidst growing ecological threats, aiming to sustain these critical habitats into the future.
