We noticed a White-winged Chough nest. We thought the chicks must have fledged as there were no birds on the nest. Just as somebody made that comment, first one, then another bird, then another arrived until there were about five. The birds did make a soft, single note, wood-wind like noise that the Morcombe and Stewart eGuide to Australian Birds termed a recording of the noise a wail. The first bird sat on the nest while the remaining birds perched on the branches around it.
