Koshi Tappu Wildlife Reserve is newly promoted wildlife reserve situated on the flood plains of the Sapta-Koshi River in Eastern Nepal. It is the largest wetland area (Ramsar site), draining seven major rivers from the great Himalayan zone into the Sapta Koshi (7 rivers). The habitat is a combination of scrub grassland and deciduous riverine forest with more than 280 bird species including 20 duck species, 2 species of ibises, many storks, egrets and herons. The endangered swamp partridge and Bengal Florian are found here. The Koshi Barrage is an extremely important resting-place for migratory birds. The last surviving population of wild buffalo or arna is also found here. During the Koshi Tappu Safari at dusk and dawn, you will see many varieties of birds and animals sitting along the Sapta Koshiriver.
