Species Wild Status

World Population:

199

IUCN Red List Status:

Critically Endangered

CITES Listing:

Appendix I

Threat Summary:

Decline due to habitat degradation and clearance, as well as the introduction of predators such as stoats and cats. Its range contracted substantially following first human (Maori) occupation of New Zealand around 1200 years ago where the birds were hunted as food and to make clothing. European settlement caused the species' catastrophic decline. Has been intensively managed to ensure its survival and will continue to require help.

Range:

Restricted (translocated) to Maud, Inner Chetwode, Pearl and Codfish Islands, New Zealand.

Habitat:

Ground dweller of forest substrate and low scrubland. Formerly from sea-level to 1200m (3936 ft).

Wild Diet:

Feed on fruits, berries, nuts, seeds, green shoots, leaf buds, roots, rhizomes, tubers, bark, stems, moss and fungi. Some main food items include Blechnum fern fronds, Dracophyllum, Gahnia and Astelia, plus Lycopodium, Schizaea, Cyathodes, Olearia, Thelymitra, Oreobolus and Carex. Also important is fruit of Fuchsia, Agathis australis leaves as well as fruits and leaves of rimu Dacrydium cupressinum.

Ecology and Behaviour:

Are lek breeders-males clear track and bowl systems where small bowl shaped areas are linked by pathways, often up on ridges where sound will carry. From there, at night, the booming sounds of the males carry far and wide to attract females. Booming may be stimulated by an abundance of pollen early in summer, indicating that sufficient food will be available for families. Normally solitary outside breeding season.

Clutch and Egg Size:

2 to 4 ovoid eggs, more pointed at one end, 50.5 x 36.5mm (2 x 1.4 in).

Breeding Season:

December-February. Nest is mossy burrow in rock crevice.
