This naturally scarce species may not tolerate degraded forest; it has a moderately small population and as logging operations increase within its range it is likely to suffer a moderately rapid population reduction. It consequently is classified as Near Threatened.

Geographic Range [top]

Range Description:Coracina holopolia is endemic to Bougainville, Papua New Guinea and six islands in the Solomons Islands. It is generally scarce, although most common in the hills. Its tolerance of logged and degraded forest is poorly known (Cain and Galbraith 1956, Schodde 1977, Coates 1990, Webb 1992, Buckingham et al. 1995, Schofield in litt. 1995, G. Dutson pers. obs. 1998).

Population [top]

Population:The global population size has not been quantified, but the species is described as generally rather scarce but common on Bougainville and Buka islands (del Hoyo et al. 2005).

Trend Justification:  There are no data on population trends; however, logging is intensifying on the Solomon Islands and is probably causing this species to decline at a slow rate.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:UnknownContinuing decline of mature individuals:Unknown
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No
No. of individuals in largest subpopulation:100

Habitat and Ecology [top]

Habitat and Ecology:It occupies the canopy of hill and lowland forest from sea-level to 950 m.

Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):4.6
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): Lowland forest throughout the region is threatened by increasingly widespread logging, but as a large proportion of this species's population appears to inhabit forest unsuitable for logging, it is probably declining only relatively slowly.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
None is known.

Conservation Actions Proposed
Monitor populations at known sites. Study its tolerance of degraded forest. Protect primary lowland and hill forest at suitable sites where it is known to occur.
