Rajendra - small locality adjacent to kumar Prasana co op soc behind Wanawadi shamshan bhoomi SRPF Wanwadi Pun Parmar Nagar, Wanwadi Pune Maharashtra

My Observations:
I m a resident of Pune & I used to stay in a old style independent house with dense locality on M.G.road camp Pune where i used to get up with the chirping of sparrows & those days they were in hundreds even they made nests in the gap between wooden purlins of drawing room on my old house on M.g.road, Some times few got killed by ceiling fans. & many used to be eaten up by Cats in the area. Many made their nests in small hole of corrugated tinnd sheet roofs of the houses in the locality.
Now i have shifted to Flat at wanawadi. I observed in new buildings its not possible to make safe nests. so there are no sparrows in our society . but the old locality of small houses just adjacent to our soc I see many sparrows & they have good & safe nesting places between the tiny roof gaps.
I have hung one PVC pipe in my car park & there some small bird has already made a nest. So i think other than mobile towers. the reason for disappearing sparrows is they dont get safe 7 right place for nesting
