Endemic to Rimatara.
This warbler is everywhere on the island with a predilection for the valley bottoms and horticultural areas.
The most common cries are “tip, tip, …” spaced and repeated one or more times. There is also an alarm call “chrou …”. More melodious though hardly heard. During social interactions, dry clicks that sound like cries from geckos and quail calls are emitted.

Scientific Name: Acrocephalus rimitarae (Murphy & Mathrews, 1929)
In 2002, the population of Rimatara Reed-warbler was 5700 individuals. The census conducted in 2017 gave 958 estimated individuals.
The species is therefore in danger because its presence is drastically reduced and restricted to this unique and small island (800 hectares). The intrusion of the black rat on this still protected land would have a disastrous impact on the entire local birdlife.
