Sumit - Shakti Apartments Sector 14 Panchkula Sector 14 Panchkula Haryana

My Apartments society had sparrows around 2004-2005. I remember videographing few of these. But a mobile tower came up in 2005 end of year and after that the sparrows have been declining, rather not seen. Recently I saw 2-3 sparrows in my area. Can I do something to save them?

Our place has lot of pigeons and squirrels. But sparrows are missing.

Thanks
Sumit
