A significant drop in aquatic bird species has been recorded in the wetlands around the Narayani and Rapti rivers along Chitwan National Park (CNP) this year, according to preliminary findings from a recent bird census.
CNP buffer zone coordinator and ornithologist Manish Limbu reported that only 28 species of aquatic birds have been identified so far, compared to 47 species recorded last year. The decline is particularly notable among smaller bird species.
Species such as the northern lapwing (Jure Hutityaun) and the greater painted snipe (Chitra Danga) were not sighted this year, while the populations of ruddy shelduck (Chakhewa) and bar-headed goose (Khoya Hans) remained stable. On a positive note, the black-headed bunting (Kalo Tauke Lek Chari) was observed in the area for the first time.
Experts attribute the decrease in bird species to increasing water pollution, which is believed to discourage the arrival of migratory birds. Many of the aquatic birds spotted in the region have migrated from northern areas such as Russia, China, and Mongolia, seeking food and warmer climates.
The census, which began on January 4, is being conducted nationwide with support from various organizations. In Nawalpur, it will cover the western part of Chitwan National Park and its lakes and ponds over two days starting January 11. The national census is set to conclude on January 19.
The findings emphasize the need for concerted efforts to protect aquatic ecosystems and address water pollution to safeguard migratory and resident bird populations in the region.
