The Black Stilt
Kaki/black stilt
(Himantopus novaezelandiae) are one of the
world's rarest and most endangered birds. Once widespread
and common in many parts of New Zealand, kaki are
now restricted to the Mackenzie Basin, South Canterbury.
It is believed that their decline was caused mainly
by the introduction of mammalian predators (e.g.
ferrets, feral cats) and habitat modification
following European colonisation.
Adult kaki look very distinctive
with their completely black plumage, long red legs
and fine black bill. Young kaki go through various
black and white phases before becoming fully black
at around 18 months. Kaki live in braided rivers and
wetlands, feeding on aquatic invertebrates, small
fish and molluscs. Kaki are the only river bird to
remain in the Mackenzie Basin throughout the year.
