'''Kiwi''' are any of the five species of small flightless birds [[endemic]] to [[New Zealand]] of the genus '''Apteryx''' (the only genus in family '''Apterygidae'''). At around the size of a domestic chicken, kiwi are by far the smallest living [[ratite]]s, although in comparison to their body size their egg (weighing as much as a quarter of the adult bird's weight) is proportionately the largest of all birds. Kiwi are nocturnal and live mainly by foraging with their long beaks for [[earthworm]]s and other invertebrates in leaf litter, which they find using their sense of smell, which is unusually well-developed for a bird. Unusually for a bird, their nostrils are positioned at the [[distal]] end of the beak. | '''Kiwi''' are any of the five species of small flightless birds [[endemic]] to [[New Zealand]] of the genus '''Apteryx''' (the only genus in family '''Apterygidae''').
