Red List Category & Criteria:	Near Threatened ver 3.1
Year Published:	2012
Date Assessed:	2012-05-01
Assessor/s:	BirdLife International
Reviewer/s:	Taylor, J. & Butchart, S.

Facilitator/s:	Evans, M., O'Brien, A., Shutes, S., Starkey, M., Symes, A., Taylor, J.
Justification: This species is listed as Near Threatened because it probably has a moderately small population, which is likely to experience a moderately rapid population decline in the next ten years, owing to habitat loss to shifting agriculture. Surveys of the population and close monitoring of threats are required to confirm its status.

Geographic Range [top]

Range Description:	Bernieria cinereiceps is found along the entire length of the eastern rainforest belt in Madagascar, being rare or completely absent below 800 m (ZICOMA 1999). Within its high-altitude habitat it is common (ZICOMA 1999). The species probably has a relatively small population, given its restricted distribution.

Population [top]

Population:	The population size of this species has not been quantified, but it is described as fairly common in parts of its range.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	This species inhabits primary montane forests, being especially abundant at higher elevations (1,400 m-1,800 m), although it appears to be absent from slightly drier forests in rain-shadow (ZICOMA 1999). It is not found in disturbed forest (del Hoyo et al. 2005). It feeds chiefly in the understorey on small insects gleaned from mossy tree-trunks (Evans et al. 1992). Nesting has been recorded in November and juveniles have been seen in November-December (del Hoyo et al. 2005). A record of three adults feeding two chicks at a single nest suggests it is a cooperative breeder. Its nest, in which is lays three eggs, is bowl-shaped and made from moss, lined with dry grass and palm fibres, and situated 1-2 m above the ground on a horizontal fork or small branch (del Hoyo et al. 2005).
Systems:	Terrestrial

Threats [top]

Major Threat(s):	Any significant decline or loss of its forest habitat, e.g. through slash-and-burn cultivation by subsistence farmers (ZICOMA 1999), could seriously affect the species.
