Masafuera Rayadito



The Masafuera Rayadito, Aphrastura masafuerae, is a rare bird endemic to Alejandro Selkirk Island in the Juan Fernandez Islands. The species is a member of the ovenbird family and only one of two species in the rayadito genus. The species' natural habitat is humid montane scrub, dominated by tree ferns (Dicksonia externa) and ferns (Lophosoria quadripinnata) between 800-1300m above sea level (though they will descend lower during the austral winter).

Masafuera Rayaditos travel in pairs while feeding on arthropods; feeding occurs in the wood understory and occasionally on the ground in the leaf-litter. Nesting occurs at high altitudes (above 1200m), in small natural crevices in rocks.

The Masafuera Rayadito is a critically endangered species. The species once occurred on Surveys of the species in the 1980s found between 500-1000 birds but by 1992 that had dropped to 200 and by 2002 only 140. The species is threatened by introduced species, particularly goats which trample and degrade habitat, but also probably rats and feral cats.
