Shweta - Ram nagar crossing Roorkee Uttarakhand

The time period that I'm talking about is when i was a kid and use to go to school. There used to be an adequate number of sparrows around at time. I could see them early in the morning, chirping around here and there! But, its been years now, since I've seen sparrows in this area. Now.. Not even a single sparrow can be seen here. Its really sad that they aren't here anymore. But, I wish if I could bring them back to this place.
