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.
Facilitator/Compiler(s): Benstead, P., Derhé, M., Dutson, G., Mahood, S.
Justification:
This poorly known species is likely to have a moderately small population which is probably declining owing to introduced cats. It is consequently classified as Near Threatened.

Geographic Range [top]

Range Description: Megalurulus whitneyi is endemic to the mountains of Espiritu Santo in Vanuatu and Guadalcanal in the Solomon Islands. On Santo, it is usually found at 500-1,500 m but occasionally down to 150 m. Although there are few records of this shy species, it appears to be fairly common (Medway and Marshall 1975, Bregulla 1992, G. Dutson pers. obs. 1997-1998, Dutson 2011). On Guadalcanal, it is only known from three records at the type locality at 1,200-1,550 m (Galbraith and Galbraith 1962, Gibbs 1996, G. Dutson pers. obs. 1997-1998) but is likely to be more widespread (Dutson 2011).

Population [top]

Population: The global population size has not been quantified, but the species is described as probably locally relatively common but its status is difficult to determine because of its shy and retiring nature (del Hoyo et al. 2006).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It occurs in upper montane forest with dense undergrowth at 500-1,550 m, rarely down to 160 m in wet forest on Santo, and at 1,200-1,550 m in forest with both dense bamboo undergrowth and sparse undergrowth on Guadalcanal (Dutson 2011).

Systems: Terrestrial

Threats [top]

Major Threat(s): As a terrestrial species, it may be threatened by feral cats on montane Guadalcanal (Leary 1991) and this may also apply on Santo (Dutson 2011).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
None is known.

Conservation Actions Proposed
Conduct surveys on Guadalcanal to determine the species true distribution. Protect high-altitude forest on Santo and Guadalcanal. Research the effects of introduced predators on nest success.
