Little Spotted Kiwi - photographer: Simon FordhamDay visitors to Tiritiri Matangi are likely to see all but one of the translocated species of bird present on the Island. The one they almost certainly won’t see is the little spotted kiwi because, like all Kiwi, they are nocturnal. For those fortunate enough to spend the night on the Island, a night walk can be a most rewarding experience. As the Kiwi population grows and the birds become increasingly tolerant of human presence, the chance of an encounter has gone from being a possibility to a probability.

Five pairs of little spotted kiwi were released on Tiri in 1993, followed by six more birds two years later. A 1997 census showed the birds were breeding well with a population of around 25. This included the largest ever little spotted kiwi recorded at the time, a female weighing almost 2kg (this has since been surpassed on Tiri).

Endemic to New Zealand, there are also four other distinct species of kiwi. By far the most common are the brown kiwi (in the North Island) and tokoeka (on Stewart Island). The others are the rowi, which is by far the rarest kiwi species, and the great spotted kiwi. The little spotted is the smallest species of  kiwi. The only certain populations are on offshore islands, with most of these on Kapiti Island. 

Despite being our national symbol, the kiwi is rarely seen outside of captivity. It is a tragedy that, without outside help they are expected to all but disappear from the mainland within fifty years. The reason for this is predation. Although adults can generally fend off attacks from all but dogs, other predators, particularly stoats, wreak havoc on nests and juvenile populations. Juveniles leave their parents very early and it is believed that only 1-5% survive their first year. There is some hope however, thanks to 'Operation Nest Egg', a programme whereby eggs and juvenile kiwi are removed from the wild and raised in captivity. They are then released into their original habitat when large enough to fend for themselves.

On Tiritiri Matangi, there is a census of little spotted kiwi every five years. In July 2012, 32 individual birds were caught and a further three were seen. Four of the captured birds were from the original translocation in 1993. The estimated total population for the Island is 80-100 birds, a 38% increase on the 60-70 estimated in 2007. During the 2012 survey, five males were found incubating eggs. These are the earliest nests ever recorded for little spotted kiwi, two months earlier than expected.
