Systematics History

Editor’s Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.Forms a species-group with M. keiensis and M. geelvinkiana. All races very similar and validity has been questioned, as distinguishing characters are not obvious and provenance of some material currently in doubt; species may be better considered monotypic. Proposed race salvadorii included in beccarii, and pusilla in nominate. Four subspecies tentatively recognized.

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

Lowland and floodplain gallery forest, tall secondary growth and trees in clearings, sometimes dense savanna and coconut stands, up to 800 m, although only common up to 400 m.

Movement

Wandering groups noted in extreme E of range, but whether there is true nomadism or birds simply range over large home ranges over several weeks is not known.

Diet and Foraging

Lichen, bark fungus, and probably termites; insect remains, tiny black seeds, yellow fruit flesh and flowers in stomachs.

Sounds and Vocal Behavior

Calls include high-pitched short notes such as “tsit” or “tsee”. Also short phrases of 2–4 different notes, e.g. “tsee-tsi-tsit”.

Breeding

Sept (1)–May. Nest

in hole excavated in arboreal termitarium, in one case that of Microcerotermes biroi about 2 m above ground on the trunk of a small tree in secondary forest. Eggs 2–3, size 16·2 mm × 14·3 mm (n = 1) (1).

Conservation Status

Conservation status on BirdlifeLC Least ConcernNot globally threatened. CITES II. Very uncommon or local on Sepik R, but common in Owen Stanley Range foothills, SE Papua New Guinea, where density estimated at 20 birds/km². Common, Bismarcks and Bagabag. Abundance may be underestimated owing to unobtrusive habits, e.g. infrequently seen near Port Moresby yet calls suggest it to be most abundant parrot in area.
