Justification of Red List category
This species qualifies as Critically Endangered since it has an extremely small range and probably only one viable population persisting on an island where there has been a continuing decline in the extent of habitat. However, the situation may be improving as this population appears to have substantially increased in the last 20 years, at least partly owing to a variety of habitat management measures. The species may be more adaptable than its present range suggests as a number of territories are now in open woodland with housing encroachment, and an increasing number of tree species are used for nesting. Following the successful reintroduction of birds to Denis Island, this species will warrant downlisting after five years if both populations are still self-sustaining, as the species occurs at multiple locations; but in the meantime it retains this classification as a precautionary measure.

Distribution size (breeding/resident):
Land-mass type - oceanic island - Oceanic islands are islands or island groups that are <200,000 sq km in size and separated from other land masses by >200 m sea depth. Generally Oceanic islands are islands or island groups that are <200,000 sq km in size and separated from other land masses by >200 m sea depth. Generally they have never been connected to a continental area by a land-ridge, and are volcanic in origin.
