High grassland in New Zealand

Where it lives

It lives in high grassland in the south of New Zealand. Snow tussock grass covers the hills there. Cold winters bring deep snow.

The bird needs dense grass for cover. Some birds now live on small predator-free islands. These islands are its safety net.

Grass stems, bugs and seeds

What it eats

It eats the soft base of grass leaves. The bird holds a leaf with one foot and strips it. It also takes bugs, seeds and fruit.

It feeds mostly in the early morning. Grass alone gives it little energy. So it must eat for much of the day.

Food of the South Island Takahe
It strips the soft base from grass leaves, holding each one with a foot, and also takes bugs, seeds and fruit.

1 or 2 eggs on the ground

The breeding cycle

A pair builds a nest of grass on the ground. The female lays 1 or 2 eggs. Both parents sit on them for about 30 days. The chicks are black and fluffy.

They can feed themselves within a few days. Young birds stay with the parents for months. A takahe may live over 20 years.

Endangered but rising

Conservation

This species is rated Endangered by the IUCN. Stoats and cats kill young birds. Deer eat the grass the bird needs. Snow slides can bury whole nesting grounds.

Rangers track every bird by radio. Moving birds to safe islands has raised the numbers. Fewer than 600 birds now live in the wild.

Quick hits

Five things to remember

  • Its name honours a scientist from long ago.
  • A doctor found it again in 1948.
  • It cannot fly, but it can run fast.
  • The chick is born with a dark fluffy coat.
  • The whole world population would fit in one hall.
