Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Contributor(s): Dutson, G. & Iles, M.
Facilitator/Compiler(s): Benstead, P., Derhé, M., Dutson, G., Mahood, S., O'Brien, A. & Pilgrim, J.
Justification:
This species is classified as Near Threatened because it has a moderately small population with is thought to be declining owing to predation by village dogs.

Geographic Range [top]

Range Description: Hypotaenidia rovianae is known from New Georgia and Kolombangara, with reports from Kohinggo, Wana Wana (= Vonavona) and Rendova in the Solomon Islands (Diamond 1991a). It is locally fairly common in thickets and young plantations on Kolombangara, but there are few records from other islands (Diamond 1991a, Gibbs 1996, G. Dutson pers. obs. 1997, M. Iles verbally 1998).

Population [top]

Population: G. Dutson (in litt. 2002) estimated that fewer than 10,000 individuals survive, so it is placed in the band 2,500-9,999 individuals here. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It inhabits forest, especially secondary growth, young plantations, rank grassland, abandoned gardens and other edge habitats.

Systems: Terrestrial

Threats [top]

Major Threat(s): As a flightless species, it may be under threat from introduced predatory mammals and village dogs but there is no evidence of decline on Kolombangara, where it has presumably increased to populate the large forestry plantations (G. Dutson pers. obs. 1997, M. Iles verbally 1998).

Conservation Actions [top]

None is known.

Conservation Actions Proposed
Survey on Kohinggo, Wana Wana and Rendova to determine current status there. Investigate threats and ecology. Reduce levels of predation by dogs through community education programmes.
