Saw 3 of them perched on a large peepal tree around dusk. 1 would fly in circles and come to sit on the tree (not sure if it was the same one flying always) the remaining 2 would stay perched on the tree. This would happen several times and around 7pm they would fly off into the dense bushes/trees around the nearby water canal.They looked a bit on the smaller(leaner) side, may be juveniles(not sure)? Took a very grainy pic from far away.
