Four species of cranes are found in Assam, all of which are seen occasion- ally. Recent reports of sighting show small numbers. For one species, the Hooded crane, the only record pertains to the year 1899. The Bar headed goose on the other hand, is a fairly common winter visitor. During winter a large number of migratory waterfowl are captured with the help of nets, which is a dangerous practice for the rare birds.
