The number of winter birds visiting Koshi Tappu Wildlife Reserve has been found to have decreased this year. The recent water bird census conducted in Koshi Tappu Wildlife Reserve (KTWR) showed that while the overall number of individuals has decreased, there has been an increase in the diversity of bird species. The census, which began in the second week of January and was conducted by the Himalayan Nature Society under the coordination of the Department of National Parks and Wildlife Conservation, revealed a decrease in the number of birds in KTWR.
