Monica Medappa - Jayanagar Jayanagar Bangalore Karnataka

I remember running to my window to see the chirping sparrows when i was a kid.a sparrow family had found a home on our ceiling outside and for generations they stayed on until they mysteriously disappeared after a few years.I remember sitting by my window and spending hours watching them.My family kept water and grains for the little ones every single day.i miss my little friends.is there any way i can attract them back to my home?i stay in Bangalore South(Jayanagar)and yes we do have a mobile tower just behind our house.is there any possibility of them coming back to us?
