 The authors of the study propose this is a survival mechanism to reduce harassment, increase chances of acceptance into the group and hence chances of future reproduction.The species breeds in natural hollows of trees or lower vegetation like tussocks of grass or shrubs.Where trees are available, the nest site may be over 4 metres from the ground, perhaps as high as 18 m. Eucalpyts are a favoured tree species, and pandanus are also selected.
