About the Nauru Reed Warbler
The Nauru reed warbler is a passerine bird endemic to the island of Nauru in the Pacific Ocean. It is one of only two native breeding land-birds on Nauru and it is the only passerine found on the island. It is related to other Micronesian reed warblers, all of which evolved from one of several radiations of the genus across the Pacific. Related warblers on nearby islands include the Caroline reed warbler, with which the Nauru species was initially confused, and the nightingale reed warbler, which was formerly sometimes considered the same species.

How to identify it
The Nauru reed warbler is a medium-sized and warmly coloured reed warbler, with a relatively light build. The entirety of the upperparts are dark brown, with the rump and uppertail coverts slightly brighter than the tail and mantle. When closed, the wing is the same colour as the mantle, short and rounded. The wing does not reach the start of the tail feathers, which enhances the appearance of a long tail. Close inspection of the wing reveals darker centres to both the greater coverts and tertial feathers.
