These days we are missing the sight of these birds. Earlier sparrow was found everywhere chirping in the morning. I remember the old days,when chirping of these birds was the sign of the starting of morning. But now it all vanished and we rarely see sparrow. What is the cause of their disappearing from the scene ? Nobody knows the exact answer. Some say , it is due to the heavy use of mobile networks, which disturbed their natural living habits. Can we do something for it ! Conserve these birds to protect the environment.
