If there are no ground-dwelling flesh-eaters, as is the case on the Aotearoa islands, many flying creatures may abandon their powers of flight and take up a ground-dwelling existence. In these areas most of the habitats on the ground may be occupied by animals whose ancestors once flew. On South Island there are large areas of grassland to the east of the central mountain chain of the Southern Alps. These are grazed by a flightless pterosaur that is related to the kloon. This is the wandle and it is quite a large animal, being about 2 meters (6 feet) high at the hips. Like the kloon, its herbivorous diet has meant that all similarity to the carnivorous flying ancestor has been lost. Its face has taken on the appearance of one of the sprintosaurs because it must accommodate a similar tooth
