'''Kiwi''' are any of the three 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 quater 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 earthworms and other invertebrates in leaf litter.

Kiwi are nocturnal and live mainly by foraging with their long beaks for earthworms and other invertebrates in leaf litter, which they find using their sense of smell which is unusually well-developed for a bird.

All three kiwi species are protected and much reduced in range, though the large size of their eggs does offer some protection against the depradations of [[rat]]s, compared to other ground-nesting native birds such as the [[kakapo]] and [[takahe]].
