Population [top]
Population: The global population size has not been quantified, but the species is described as fairly common within its very small range (Cheke et al. 2001).
Trend Justification: The population is suspected to be stable, but may be declining very slowly owing to ongoing habitat degradation.
Current Population Trend: Decreasing
Additional data:
? Number of mature individuals: Unknown ? Continuing decline of mature individuals: No
? Extreme fluctuations: No ? Population severely fragmented: No
? Continuing decline in subpopulations: No
? Extreme fluctuations in subpopulations: No ? All individuals in one subpopulation: No
Habitat and Ecology [top]
Habitat and Ecology: It generally occurs in flowering trees and shrubs in stunted (and mossy) forest above 1,500 m. It has been recorded breeding in January-July.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: No

Threats [top]
Major Threat(s): Although its area of occupancy must be very small, its habitat is apparently fairly secure.
Conservation Actions [top]
Conservation Actions: Conservation Actions Underway
None are known.
Conservation Actions Proposed
Determine whether habitat loss poses any threat within its altitudinal range. Survey to quantify the population size. Grant protection to areas of suitable habitat to safeguard against future threats.
