Remember that small sparrow which used to sit at a distance when mother used to take rice and clean it off from dirt etc? The sparrow used to be bold but not enough to steal anything under our noses.
Indiscriminate cutting down of trees has made this bird fly away from cities as there are no nesting places. The pollutions of all sorts including Air, Water and Sound has ensured its migratory path.
Even when this sparrow built its nest inside our houses, we used to watch it with glee and jump in joy the day we hard the chirping of small ones.
Ooh what a joyous sight it was!
Ooh my sparrow where have you gone?
Is this the traffic signal as Madhur Bandarkar would say showing RED signal for the human kind?
