The Rajarhat wetlands, situated about 15km from the city of Kolkata, have become a hunter's paradise. Hunters use trap nets that are placed in strategic locations across water bodies and marshes. These nets are about 20-30 feet in length and 4-5 feet in width and are strung across bamboo poles. They are made of strings so thin that they are not visible from a distance unless viewed carefully. Birds fly into these nets and get entangled in them. Unable to escape, they succumb at the hands of the hunters or await a slow, painful death.
