This youngster has been hanging around and calling. An adult male Koel planned in the tree near it and called but it seemed unsure of him. It does the quivering and begging postures when its host parent, a Red Wattlebird, comes close but it did not get fed while I was there. It flew to the nearby creek and ate some blackberries. It then flew up to what I'm guessing is its old nest, sitting in it and hanging around it.
