Cuculus heinrichi heinrichi Collar and Andrew (1988)
|Taxonomic Source(s):||del Hoyo, J., Collar, N.J., Christie, D.A., Elliott, A. and Fishpool, L.D.C. 2014. HBW and BirdLife International Illustrated Checklist of the Birds of the World. Lynx Edicions BirdLife International.|
|Taxonomic Notes:||Cacomantis aeruginosus (del Hoyo and Collar 2014) was previously listed as C. heinrichi; the name aeruginosus has priority.|
|Red List Category & Criteria:||Near Threatened ver 3.1|
|Facilitator/Compiler(s):||Benstead, P., Bird, J., Taylor, J. & Symes, A.|
This species is listed as Near Threatened because it is thought to have a moderately small population, which may be experiencing a continuing decline owing to forest loss. However, little is currently known about the population size and structure of, and threats to, this species. Further information may indicate that its classification needs revision.
|Previously published Red List assessments:|
|Range Description:||Cacomantis aeruginosus is restricted to the Northern Maluku Endemic Bird Area, Indonesia, where it occurs on Halmahera and Bacan (BirdLife International 2001).|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||This species has a relatively small range, within which forest habitats have declined and hence, the global population is suspected to be moderately small. It is placed in the band 10,000-19,999 individuals, equating to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.|
Trend Justification: The population is inferred to be undergoing a continued decline owing to forest clearance and degradation, although the rate of decline may only be slow or moderate.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It inhabits montane forest at 1,000-1,500 m on Halmahera, but occurs lower (800-1,200 m) on Bacan with recent reports from as low as 100-450 m. No information is known about breeding and foraging behaviour.|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Generation Length (years):||4.2|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||It may be vulnerable to forest loss within its range owing to the expansion of small-holder farming and subsistence logging.|
Conservation Actions Underway
None are known. Conservation Actions Proposed
Survey for this species and calculate density estimates in order to revise its global population estimate. Assess its dependence on forest. Calculate rates of forest loss using remote sensing of satellite images. Protect areas of suitable habitat and safeguard against encroachment and degradation.
