In odisha, I don't remember seeing any brown feathers in the pied kingfisher. Around 2001-2002 they were numerous in the nallahs in bhubaneshwar. We had constructed our house in old town bhubaneshwar and there were many pied kingfishers hovering near by. Once I slowly climbed up the wall of a nearby garage to photograph a pied kingfisher and I had got a closeup with a 300mm lens on a film camera using slide film. Even from such close distance I don't remember seeing any brown.
