Similar species
Similar to Rimatara Reed Warbler but ranges don't overlap and albinism in Rimatara Reed Warbler usually affects anterior not posterior parts of body.
Distribution
Henderson Island, an uninhabited coral island in the south Pacific Ocean.
Abundant in its very small range. The accidental introduction of alien species like rats to the islands has to be prevented to conserve this species.
Taxonomy
This is a monotypic species.
Has been treated conspecific with Rimatara Reed Warbler and Pitcairn Reed Warbler.
Habitat
Found in forest which covers the entire islands.
Behaviour
Diet
Feeds on insects. Takes also land snails, some seeds and fruit pulp.
Forages in all levels of forest, often in family groups. Takes items from the vegetation and from the ground.
