Birding Site Guide

Koshi Tappu Wildlife Reserve lies on the flood plains of the Sapta-Koshi in Saptari and Sunsari Districts of Eastern Nepal. The reserve is defined by the eastern and western embankments of the river. This site and the Kosi Tapu National Park accommodation is found at Kosi Tapu Tented Camp on the edge of the park. 

This site and national park are situated in the east of country, with the newly constructed paved road from Kathmandu to Kosi, it is now far easier to reach than in 1997. However it is not a motorway and still a long days drive of c300+km through the dry Sal forest. There are opportunities to do a little birding along the way, though birds may be very few in the dry season. Arriving at Kosi continue over the reservoir barrage and out to the countryside a short way, at Kosi Tappu follow the signs for the army base or national park (near each other, the latter badly signed) for accommodation. In our visit there was no accommodation anywhere; we were offered a mattress on top of some rat infested potato sacks at the back of a stall, which we were eager to reject, then finally a goat shed (yes with goats) at the army, which we took- and got pestered by goats trying to get back in all night! 

The range of habitats at Kosi is varied from marshes and forest to the open waters of the reservoir. Here it is possible to see Pied Harrier or in winter the huge numbers of ducks.
