Rutvij Oza - Sus Road Pashan Pune Maharashtra

It's as recent a development as less than 15 days since I noticed that some sparrows have built a nest just outside by balcony between the wall and an insulated pipe coming from the building's solar water heating system, so, I have started putting out some water and some crushed "mahabaleshwar chana" for them to have. There seem to be 2 couples having laid eggs and I believe that the babies should start flying soon. Now, the sparrows have started feeling comfortable around me and are now frequenting my balcony, hopefully for the water and the munch.

Anyway, I would like inputs from the organisers about what should be offered to them, to make their numbers grow around me & my locality.
