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): Symes, A. & Butchart, S.
Contributor(s): Torres-Mura, J.
Facilitator/Compiler(s): Capper, D., O'Brien, A., Sharpe, C J
Justification:
This species is classified as Near Threatened because it has an extremely small range on a single island. Although its population is currently thought to be stable, it is susceptible to stochastic events and human impacts.

Geographic Range [top]

Range Description: Anairetes fernandezianus is endemic to Isla Robinson Crusoe in the Juan Fernández Islands, Chile (Ridgely and Tudor 1994). It is apparently common within this restricted range, and the population was estimated at a stable and secure 5,000 birds in the mid-1980s (Brooke 1987).

Population [top]

Population: The population was estimated at 5,000 individuals in the mid-1980s (del Hoyo et al. 2004)
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It is found in all wooded habitats: undisturbed forest, luma Nothomyrica fernandeziana parkland (even where the understorey has been heavily degraded by cows), Eucalyptus woodland, and even (although not commonly) among the miscellany of exotic vegetation in Cumberland Bay (Brooke 1987).

Systems: Terrestrial

Threats [top]

Major Threat(s): Threats include predation by cats (Brooke 1987) and possible, but unquantified predation, by introduced Red-backed Hawk Buteo polysoma from Isla Alejandro Selkirk (Hahn and Römer 2002).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
The Juan Fernández Islands were designated as a national park in 1935 (protected from 1967) and a biosphere reserve in 1977. The Chilean government began a habitat restoration programme in 1997 (J. C. Torres-Mura in litt. 1999), and the islands have been nominated for World Heritage listing (Hulm 1995).

Conservation Actions Proposed
Regularly monitor population to detect any trends. Implement control measures against cats. Study possible effects of predation by Red-backed Hawk and develop eradication plan if necessary.
