The Kagu is a flightless bird with grey plumage; its pale colouring has led to the name of 'ghost of the forest' by local people (4). The sexes are similar in appearance with mainly ash-grey plumage apart from black barring on the wings that is only visible when they are out-stretched (5). There is a prominent crest of feathers on the back of the head, which may be erected in display, and the legs and bill are orange in colour (5).
