Juan Fernandez Tit-tyrant Anairetes fernandezianus

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.

Identification
13 cm. Small streaky flycatcher. Ashy-grey upperparts. Black head and long spiny crest feathers, with some white streaking. Whitish underparts heavily streaked black. Female has shorter crest. Voice Not reported. Hints Conspicuous at woodland edges.

Distribution and population
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 justification
The population was estimated at 5,000 individuals in the mid-1980s (del Hoyo et al. 2004)

Trend justification
The population was estimated to be stable and secure at 5,000 individuals in the mid-1980s (Brooke 1987).

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).

Threats
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 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.
