The flight feathers have different black-and-white wing patterns. Subspecies show a range of pink to grey colored plumage with distinctive overall size and leg length. For instance, harterti is greyer than others, while insularum is relatively more streaks. They have a melodious call which is a surprise as it seems they’d have haunting calls.
