Thanks all for the comments.

Saktiji, I agree Bangalore has changed a lot in the past few years and the effect can be seen on the climate, which is becoming hot from the quiet and cool city it used to be .

Murugan, It had just caught it and it flew to this side. I did not see him in the garden where I had seen it flying down. I think it was about to start eating, when I suddenly reached the spot, so it gave one look at me and immediately took off. I thought it had flown off and didn't expect it to be here, else I would have approached quietly .
