Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Más a Fuera Rayadito faces severe threats from invasive European rabbits that have devastated the native vegetation of Alejandro Selkirk Island through intensive grazing and soil erosion. Introduced goats and cats compound the pressure, with cats potentially preying on birds while goats continue habitat degradation. The species' extremely restricted range on a single remote island makes it exceptionally vulnerable to any environmental catastrophe or further habitat modification.

Threat summary

Habitat

Endemic to the native forests and shrublands of Alejandro Selkirk Island in the Juan Fernández archipelago, particularly favoring areas with dense understory vegetation. The species depends on the island's unique endemic plant communities that provide both nesting sites and foraging opportunities among the native ferns and shrubs.
