Sexes similar, males are slightly larger. Juveniles of rufusater similar to adults, juveniles of carunculatus very different, dark brown plumage with chestnut wash on head and rump and dark lores. Immatures similar to adults.

Distribution

Endemic to New Zealand.
Extinct in most of its original range and now confined to small protected areas and some rat-free offshore islands.

Taxonomy

Two subspecies recognized which are sometimes treated as full species:

  • P. c. carnculatus - South Island Saddleback - extreme northeast and southwest South Island and islands of Stewart Island
  • P. c. rufusater - North Island Saddleback - islands of North Islands and some fenced areas on North Island.

Saddleback has previously been placed in genus Creadion.

Habitat

Native forest. Most populations live now in areas where they have been translocated.

Behaviour

Feeds on invertebrates and berries, takes sometimes nectar. It tears pieces of bark from tree trunks to find insects beneath, they will also feed on the ground in leaf litter.
Breeding depends on food availability, may breed three times or more in a good year. The nest is a medium-sized cup made of twigs and bound together with moss or lichens. It's placed in a hole or cavity in a trunk, sometimes on the ground in a rock crevice or among dense epiphytes. Lays 1-4 eggs (carnunculatus 1 - 2).
A sedentary species.
