Itahari municipality is one of the three municipalities of Sunsari district. It is situated in the Tarai region of Eastern part of Nepal. The main rivers are Sunsari, Tengra and Budhi. Besides that there are also few man-made and natural wetlands. Itahari is very near from the mixed type of jungle popularly known as ‘Charkoshe Jhadi’ on the north, which provides ideal shelter for the birds. This is the reason why many local migratory birds as well as other birds are found to come very commonly from the jungle.
