Threat Summary:
Recently, remote-sensing techniques have shown that the lowland forest on which this species relies for nesting sites is being cleared at a rapid rate, which is likely causing the population to decline precipitously. It is suspected that up to a third of tree cover may be lost from the species’ range over the next three generations.
Range:
Found in New Britain, E Papua New Guinea.
Habitat:
Occurs up to 950 m (3116 ft). Found in forest and partly cleared areas, most common in lowlands.
Wild Diet:
Feeds on fruits of coconut Cocos nucifera, Melanolepis multiglandulosa and Ficus sp., as well as the flowers of C. nucifera, Eucalyptus deglupta and Cryptocarya sp.
Ecology and Behaviour:
Keeps mainly to forest canopy; usually seen singly, in pairs or small groups; makes presence known with series of discordant notes. Most active in early morning and late afternoon. Acrobatics seen before roosting.
Clutch and Egg Size:
2 or 3 elliptical eggs, 52.0 x 31.5 mm (2 x 1.2 in)
