This species is restricted to a single very small island. Recent estimates suggest the population size may be much greater than was previously thought. The species is therefore classified as Least Concern.

Previously published Red List assessments:

Geographic Range [top]

Range Description:This species is restricted to Wetar, Indonesia. Although "never abundant", it was recorded at most forest sites in a recent survey of the island (Trainor et al. 2009).

Countries occurrence:
Indonesia (Lesser Sunda Is.)
Additional data:
Continuing decline in area of occupancy (AOO):Yes
Extreme fluctuations in area of occupancy (AOO):NoEstimated extent of occurrence (EOO) - km2:4000
Continuing decline in extent of occurrence (EOO):UnknownExtreme fluctuations in extent of occurrence (EOO):No
Continuing decline in number of locations:Unknown
Extreme fluctuations in the number of locations:No

Population [top]

Population:This is a poorly known species and the population size has not been quantified. A crude estimate puts the population at 30,000-50,000 pairs (Trainor et al. 2009b).

Trend Justification:  Some habitat loss is on-going on Wetar, and the population is suspected to be in slow to moderate decline as a result.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:UnknownContinuing decline of mature individuals:Yes
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:This species occurs in most forest types, preferring the forest edge and dry forest. It feeds mainly on figs (Trainor et al. 2009).

Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):3.7
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): Extensive forest remains on Wetar, but deforestation may have increased in recent decades, with illegal logging and gold and copper mining operations threatening to affect remaining habitats, as well as on-going pressure from agriculture and road building (Trainor et al. 2009).

Conservation Actions [top]

Conservation Actions: Conservation and Research Actions Underway
No targeted conservation actions are known for this species.

Conservation and Research Actions Proposed
Conduct repeated surveys within its range to determine current distribution and abundance, as well as assess population trends and rates of habitat loss. Conduct ecological studies to improve understanding of its precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Campaign for the protection of remaining tracts of lowland woodland on Wetar.
