Raiganj is a city and a municipality in Uttar Dinajpur district in the Indian state of West Bengal. It is the headquarters of a district as well as a subdivision. The place oozes heritage. Tradition and a rich past haunt the residents of the 300-year-old town. Even the police station was set up 125 years ago and railway connectivity reached the place 115 years ago. The high school is 101 years old. Raiganj got a railway communication way back in 1896. The train used to go to Parbatipur junction in Bangladesh from Raiganj. The rail link helped the town become an important trading centre, aided by the additional benefit of waterways. Situated along the National Highway and by the side of the Kulik river is the Raiganj Wildlife Sanctuary with an area of 35 acre and buffer area of 286.23 acre. The forest, water bodies and the river attract the migratory birds like Open Bill Strok, Night heron, cormorant, little cormorant & Egrets from South Asian countries and coastal regions. Local birds like dove, bulbul, sparrow, king fisher, woodpeckers, owl, duck & cuckoo, can also be seen in large numbers. The migratory birds arrive from end of May to Ist week of July and depart from mid December to end of January. The nesting time is from July to August & egg laying from August to September. The flying training to the young ones is the best time to observe the birds, around October to November. Every winter nearly 150 different bird species arrive here from the north in numbers ranging from 65,000 to 75,000. Some of the common migratory birds seen here are Open-Billed Storks, Asian Open-billed storks, Egrets, Knight Herons, and Cormorants. Indian birds like kites, flycatchers, kingfishers, owls, woodpeckers, drongos, and bee eaters. The sanctuary has artificial network of man made canals which is connected to the River Kulik. During the months of monsoon the flood water from the river enters the plains of the sanctuary. This acts as the important source of food for most of the birds. The cathedral, Raiganj Church dedicated to St. Joseph the Worker, the patron saint of Raiganj Diocese shows the faith and support of the people of the diocese, the leadership provided by Bishop Alphonsus D'Souza S.J. and the planning and implementation by Fr. Sunny M.V., the treasurer of the diocese and secretary of the Bishop. The spacious cathedral towering towards the blue skies has exquisite glass and ceiling paintings, prominent pillars on both sides modeled on Greek pillars, beautifully carved doors and magnificent high altar with an hexagonal dome on top of it with eye-catching paintings.
