Koshi Tappu is famous for wild buffalo and has become a paradise for the birdwatcher. Located in Saptari and Sunsari district in eastern Nepal, the reserve's area (175 Sq.km.) is defined by the eastern and western embankments of the Koshi River. In 1976, the reserve was established basically to preserve the habitat of the remaining population of wild buffalo, locally known as Arna, in Nepal.
Not only does the water look beautiful, but it also has created floodplains and wetlands thus inviting many species of bird from far off places. Once on your raft, you will definitely enjoy the tranquility of the reserve. As the mild current takes your raft southwards, you will witness feathered creatures of all sorts - around 300 different species have been recorded so far.
Most of the time on the river banks, you will see 20 species of duck, heron, stork, egret, ibis - among others - either searching for their food or preening or basking. The river also has on offer the endangered gharial crocodile and Gangetic dolphin. Besides this, many more wild animals are found here.
The wetlands in the reserve beckon all sorts of bird species. These birds fly all the way from Siberia to migrate during winter. The fact that many birds that arrive here are seen nowhere else in Nepal makes this reserve a birdwatcher's paradise in its truest sense.
