Systematics History

Species name officially validated against Plyctolophus DuCrops [sic] (1). Species names goffini and tanimberensis, both used previously for C. goffiniana, are synonyms of present species (see C. goffiniana). Monotypic.

Subspecies

Monotypic.

Distribution

Solomon Is from Bougainville SE to Malaita and Guadalcanal.

Habitat

Found universally throughout forest  , up to 1700 m in cloud forest.

Movement

Not reported in large flocks, occurring mainly in pairs or groups  of 5–10 individuals.

Diet and Foraging

Eats fruits, seeds, blossom, leaf buds, epiphytes, large caterpillars and soft-bodied insects; raids native gardens, eating pawpaws and digging up sweet potatoes.

Sounds and Vocal Behavior

Flight call is a fast succession of two or three short grating notes, “reh-reh” or “ryeh-eh-eh”, repeated at short intervals. When perched, vocabulary is more diverse but mainly involves staccato series of short grating notes with a similar tonal quality to flight call.

Breeding

Until recently, unknown. Eleven nests with young, estimated to be 4–5 weeks old, recently found in Jun (3), Jul (5) and Aug (3). Nests were in natural cavities in trees, 20–25 m above ground. Brood size was 3 chicks (1), 2 chicks (9) and 1 chick (1); all nestlings had some body feathers still in sheath and primaries well developed; colour of natal down not documented.

Conservation Status

Conservation status on BirdlifeLC Least Concern

Not globally threatened. CITES II. Present species is the only island cockatoo that has not been subjected to heavy trapping for the aviary trade. Precise information lacking, but species is still common, though likely to suffer in the future as result of increased pressure from logging.
