The Anjouan brush warbler is a species of Old World warbler in the family Acrocephalidae. Clements lumps this bird into the Malagasy brush warbler N. typica. This is supported by the IUCN, whereas the IOC recognizes it as a valid species. It is endemic to the Comoros and Mayotte.
Region
Comoro Archipelago, western Indian Ocean
Typical Environment
Occurs primarily on Anjouan in the Comoros, favoring dense low vegetation, overgrown thickets, and scrubby edges. It uses secondary growth, plantations, and hedgerows as well as forest margins. Birds often keep close to the ground or mid-story, moving through tangles and reeds. Proximity to water or moist gullies is common, but it also occupies drier coastal scrub. Human-modified habitats with dense undergrowth are frequently utilized.
