So far its just for a few seconds that I have seen these birds for, either running under a thick blanket of grass or when I happened to flush them while walking.
This video was taken in Bor Wildlife Sanctuary, where me and my friends saw around 3-4 Jungle bush quails coming down a hill. We waited for them to come all the way down where there was a open patch. After a few minutes there were around 8 quails moving around us, searching for food in the leaf-litter present in-between the rocks.
We saw them for around 10 min.
This was the best sighting of these birds I ever had.
