Keya - Near my house South Office Para, Doranda Ranchi Jharkhand

Till a few months back, there were hardly any sparrows around my house. But recently I started doing some balcony gardening- put some flower pots. This summer it was too hot, so I kept a small earthen bowl of water in the Balcony. Lately I have seen sparrows visiting my place- sometimes to drink water, and sometimes hopping on the flower pots.
I guess they have started coming in search of insects. I haven't seen any nesting though, in my surroundings.
