Acrocephalus longirostris   (Gmelin)

Moorea Reed-Warbler
(Acrocephalus longirostris)

syn. Acrocephalus caffer longirostris (Gmelin), Turdus longirostris (Gmelin)


Society Islands: Mo'orea

local name:

'Otatare (Tahitian)

size: ca. 19 cm (length)

extinction date: last seen in 1981

Up to the present the Reed-Warblers of the Society Archipelago were treated as subspecies of the Tahiti Reed-Warbler (Acrocephalus caffer (Sparrman)).

According to DNA analyses it is now known that the four known forms evolved from three separate colonisations.

The Reed-Warbler species from the island of Mo'orea should be regarded, for that reason, as a full species.
