It is indeed sad and disturbing news that several hundred migratory birds have been found dead at the famous Sukh Sagar lake in southern Tripura's Gomati district on Friday. While officials are in the process of collecting information, samples of dead birds and trying to ascertain the reasons behind their deaths, local people living in the vicinity of the picturesque lake, which is also a tourist site in Tripura, have suspected that the avian guests might have died because of insecticides which are being used by village farmers in the nearby paddy fields. Tripura gets several species of migratory birds every year, with the wetlands and lakes remaining the main attractions. A few days ago, there was another disturbing news about migratory birds, this one from Kaziranga, with forest officials saying that the world-famous National Park is witnessing a lesser arrival of migratory birds in the current season. Kaziranga, which is also a World Heritage Site, also happens to be a crucial junction of the Australasia flyway and the Indo-Asian flyway, which makes it the most important stop-over for a large variety of migratory bird species from different parts of the globe. The authorities had, around the time when Kaziranga was celebrating its one hundred years of rhino conservation, identified about 480 bird species in the National Park, both resident and migratory. Forest officials have been quoted as having said that while October was the month till 2020 when migratory birds used to arrive in Kaziranga, this season their arrival was delayed by about a month. While Kaziranga is a wonderful combination of grasslands and water bodies, it is time the authorities take a serious look into the less arrival of birds there. Simultaneously, a survey is also required to find out whether the Panidihing Bird Sanctuary, Deepor Beel and other bird sanctuaries, wildlife sanctuaries, and National Parks in Assam have also experienced less arrival of migratory birds. If the answer is yes, then it calls for urgent action.
