|Scientific Name:||Mayrornis schistaceus|
|Species Authority:||Mayr, 1933|
|Red List Category & Criteria:||Vulnerable C2a(ii) ver 3.1|
|Facilitator/Compiler(s):||Derhé, M., Dutson, G., Mahood, S., O'Brien, A. & Taylor, J.|
This species has been uplisted from Near Threatened because, although its population is estimated to be larger than previously thought, it is believed to be in slow decline owing mainly to habitat loss and degradation caused by the gradual expansion of subsistence agriculture. It is therefore listed as Vulnerable on the basis that its population is small and declining.
|Range Description:||Mayrornis schistaceus occurs on the island of Vanikoro (170 km2) and its small satellite island of Buma in the Solomon Islands. The total population has been estimated at around 5,000 individuals (based on 90 encounters in 1998) (G. Dutson in litt. 2013). It is suspected to be in slow decline owing to limited habitat loss and degradation (G. Dutson in litt. 2013).|

|Population:||The global population size is described as numbering around 5,000 individuals, based on 90 encounters in 1998 that suggest a very approximate density of 36 individuals/km2 (G. Dutson in litt. 2013); this is equivalent to c.3,300 mature individuals.|
|Habitat and Ecology:||
It occurs within and at the edge of forest, and in regrowth adjacent to forest, to at least 450 m (Dutson 2011, G. Dutson in litt. 2013). It is tolerant of old logged forest but not scrubby or open habitats (Parker 1963, Gibbs 1996, Dutson 2011).
|Major Threat(s):||The primary threat to the species's habitat is from the gradual expansion of subsistence farming (G. Dutson in litt. 2013). Although there are no imminent plans for large-scale commercial logging, there is on-going pressure from multinational logging companies to exploit the forests of Vanikoro (G. Dutson pers. obs. 1997).|
Conservation Actions Underway
No targeted conservation actions are known for this species. Conservation Actions Proposed
Conduct regular surveys to monitor the population. Protect remaining tall forest on Vanikoro from logging and agricultural encroachment.
