The kea (Nestor notabilis) is endemic to New Zealand also known as the woodhen or bush hen, is
another endemic New Zealand bird belonging to the rail family. It bears the same
kind of structural resemblance to the banded rail, as the takahe does to the pukeko.
There are four weka subspecies. Stewart Island weka are only on Stewart Island,
Western weka are found in the western South Island, and North Island weka are found at
a number of North Island locations. The buff weka of the eastern South Island is
extinct in that region. |
In the early 1900s, settlers took buff weka from their
original habitat to the Chatham
Islands, where they now thrive so well they have to be controlled. |

Weka have been an ecological management dilemma because of their predatory conflict
with other native animals. Some weka have been a problem within the constrained
boundaries of offshore islands, as they eat the eggs and chicks of other threatened
birds. Normally the weka has been removed to eliminate the conflict.
The Department of Conservation killed 400 buff weka in the Chatham Islands in 2003,
to protect the critically endangered taiko which is one of the world's rarest seabirds,
and the Chatham Islands oystercatcher.
Weka were traditionally an easily obtained food source for Maori and early 19th century
European settlers. The decline of weka on the mainland has prevented Maori from
continuing 'mahinga kai' harvesting, but some iwi are today expressing the need for
conservation to allow the tradition to return. The Chatham Islands is the only
place where weka are presently hunted legally.
DoC reports that little is known about the density of the various populations.
According to DoC, the causes of decline, and the density and stability of populations
are complexly linked to the ecosystems of each locality. There are large
fluctuations in populations, possibly due to changes in food supply and adverse weather.

The smartest, most mischievous bird ...
Like the kiwi, wekas are good swimmers even though they do not have
webbed feet. It is seen drying off after a cool dip in a Fiordland stream.

The decline of weka remains a mystery as they are an adaptable, aggressive,
inquisitive and resourceful bird. They are known to be a bit of a nuisance
in rural vegetable gardens, where their favorite meal includes tomatoes and hens
eggs. Weka will also eat food scraps, rodents, and lizards. In their
indigenous habitat fallen fruit, invertebrates, snails and the eggs and chicks of
ground nesting birds are part of their diet.
