These are small birds, around the size of Barn Swallows - and always prefer high perches. They are usually seen on wires or on bare branches on top of tall trees. They are resident and found near small water bodies but make some local movements in response to rain.

The birds are generally seen in flocks of 5-10 or more. They prefer to sit in a huddle and even sleep like that on tall perches like wires during nights.

I got lucky that we stopped next to an elevated uphill road while the ground was at lower level. The birds were sitting on these wires and hence provided a rare eye level view.
