Buru Cuckooshrike Coracina fortis
BirdLife is updating this factsheet for the 2016 Red List
Please email us with any relevant information

This species's range is restricted to a single small island, within which it is scarce and local. It is therefore likely to have a moderately small global population size and is currently considered Near Threatened. It should be monitored carefully for any evidence of future population declines.

Distribution and population
Coracina fortis is restricted to Buru, Indonesia (BirdLife International 2001). In 1921-1922, it was regarded as unobtrusive but not particularly rare; in late 1989, it was sufficiently rarely encountered for no density estimates to be formulated; and in 1995-1996 a mere 14 birds were encountered at three localities, all reinforcing the notion that it is actually very local.

Population justification
The global population size has not been quantified, but the species is described as poorly known. In 1981-1982 the species was described as unobtrusive but not particularly rare (del Hoyo et al. 2005).

Trend justification
Although this species is apparently largely unaffected by habitat loss, any future changes in population trend could have significant and rapid effects, given the intrinsically small overall population size.

This species appears to be most abundant in higher-altitude primary forest with an open understorey (up to 1,500 m), although it is also recorded from disturbed habitats, lowland and monsoon forests.

As this species is tolerant of disturbed habitats and prefers high-altitude areas, it is probably little affected by current habitat changes.

Conservation Actions Underway
No targeted conservation actions are known for this species. Conservation Actions Proposed
Conduct repeated surveys in areas within and surrounding the species's range to determine current distribution and abundance, as well as assess population trends. Conduct ecological studies to improve understanding of its precise habitat requirements, tolerance of secondary habitats and response to fragmentation.
