Distribution: Australasian. Endemic to the northern and central SOLOMON ISLANDS (Bougainville, Choiseul, Santa Isabel, and possibly Makira); vagrant to PAPUA NEW GUINEA. more....

Subspecies: Monotypic.

Taxonomy: 

Movements: Non-migratory (Bildstein and Zalles 2005).

Habitat and Habits: Known from lower valleys of lowland forest or forest edge to about 1,000 m (Webb 1992, 1995, Debus 1995). This species may be better adapted to interior forest than the sympatric A. albogularis (Schodde 1977).

Food and Feeding Behavior: Probably preys on birds. One was seen feeding on a Chestnut-bellied Monarch (Monarcha castaneiventris) on Santa Isabel, Solomon Islands, by Webb (1997).

Breeding: No information.

Conservation: Poorly known and probably declining. Known from only one specimen from Bougainville and a handful from both Choiseul and Isabel (Schodde 1977, BirdLife International 2008). This species was categorized as Globally Threatened by Collar and Andrew (1988). and is presently regarded as Vulnerable by BirdLife International (op cit.) because of its limited range and the likelihood that its forest habitat is being lost. Logging on Choiseul and Santa Isabel has been extensive, and it may become a problem on Bougainville (BirdLife International op cit.). Although this species is assumed to be rare because of the paucity of records, it may have been overlooked to some extent.
