Coastal and mountain euclypt and wet forest.

Behaviour

Diet

They eat the seeds of various trees, including native pines, blue fig, acacia and eucalyptus. Also grasses and shrubs, as well as insects and some tree blossoms. They also are readily attracted to bird seed trays.

Breeding

Using a tree hollow, the nest is lined with wood shavings and dust . The clutch contains 4-8 white eggs which are incubated by the female for about 20 days; both sexes care for the young. The young fledge after about 35 days, but depend on their parents for a further 35 days.

Vocalisation

Very vocal (often while feeding), with range of calls, the commonest being a two-syllable cussik-cussik. They also have a range of harsh screeches and metallic whistles.

Movements

Nomadic movements reported in winter at edges of range, but generally sedentary.
