Many small marshlands, pools and grasslands are formed which provide a haven for birds and birdwatchers alike. The vegetation near these banks holds many passerines. In addition, large agricultural fields that lie adjacent to the reserve make fine habitat for many birds. The finest birding sites in and outside the reserves are located between Koshi Camp and down south all the way to the barrage. Within this stretch many birds and mammals are found that offer the experience of a lifetime. Koshi Tappu is the ultimate destination for any nature enthusiasts and experts visiting Nepal.
