Sparrows disappearing from Assam

Golaghat (Assam): Sparrows are disappearing from many parts of the country, and specially in Assam where electro-magnetic radiation from communication towers, use of leaded petrol in vehicles and overuse of pesticides in agriculture have been cited as some causes by scientists.
Chief scientist of the Regional Agriculture Research Centre in Lakhimpur, Prabal Saikia, said, "It is a fact that sparrows are becoming scarce throughout Assam - both house and tree sparrows."

Dutta has noted that in five nests eight couples of sparrows have been living happily despite the fact that there is a mobile tower in the vicinity.
