Central Ranges of New Guinea (Snow Mts E to Owen Stanley Range).

Distribution

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Habitat

Mid-montane oak forest at 600–2000 m, favouring drier ridges.

Movement

Strongly nomadic, fairly often penetrating lowlands to sea-level, and sometimes ranging up to 2300 m, consistently forming larger flocks than G. geoffroyi. Only seen in flocks flying high over Crater Mountain forest.

Diet and Foraging

Seeds of Castanopsis and Lithocarpus oaks are particularly favoured, and small seeds found in stomachs, but regularly visits flowering trees presumably for nectar and blossoms.

Sounds and Vocal Behavior

Quite vocal. Calls include several, mainly even-pitched, metallic whistles, as well as short nasal squeaky notes and chirrups during squabbling “conversations”. In flight, flocks produce a characteristic chime-like sound comprising short metallic notes that proceed randomly up and down the scale. 

Breeding

Jan and Oct. Nest recorded in hole 10 m up in large rotten stump, with three young.

Conservation Status

Conservation status on Birdlife LC Least Concern
Not globally threatened. CITES II. Generally rather scarce to fairly common, but extremely shy.
