Sabyasachi,

I agree with you about the habitat loss, i used to see them near lantana bushes.
But in the month of January the local residents have burnt all the bushes.and in the name of development the Bruhat Bangalore Mahanagara Palike (BBMP) are cleaning all empty plots by cutting the bushes and unwanted plants.

Ill try to document their behavior when i spot them next time.

Regards,
Akshay
