Koshi Tappu Wildlife Reserve is an example of one of the finest birding sites in Asia. Koshi Tappu was established as a wildlife reserve in 1976 with an aim to protect the last remaining population of Asiatic Wild Buffaloes in Nepal. The reserve has a total area of 175 sq. km. and is roughly rectangular in shape. The principal habitats in the reserve include: wetlands, grasslands and small patches of riverine forest. To date this is the only Ramsar Site (a wetland of international significance) in Nepal. More than half of Nepal’s birds are recorded from Koshi Tappu! Among the mammals, besides Wild Water Buffaloes, the elusive Gangetic Dolphin and Fishing Cat are occasionally seen here.
