Moorea reed warbler is a species of songbird in the genus Acrocephalus. Formerly placed in the "Old World warbler" assemblage (Sylviidae), it is now in the newly recognized marsh warbler family Acrocephalidae. It was once considered a subspecies of the Tahiti reed warbler.
Region
Society Islands (French Polynesia)
Typical Environment
Historically found across lowland valleys and riparian thickets on Moorea, using dense shrubbery, reedbeds, and secondary growth. It frequented Hibiscus and bamboo stands, forest edges, orchards, and regenerating scrub near streams. The species foraged within dense vegetation but would sing from conspicuous perches. Invasive plants (such as Miconia) and habitat conversion have fragmented suitable habitat. Predation by rats and cats likely compounded declines, especially around nests.

The Moorea reed warbler is a Polynesian island specialist confined to Moorea in the Society Islands. It was formerly treated as a subspecies of the Tahiti reed warbler but is now widely recognized as a distinct species. Habitat loss, invasive plants, and introduced predators likely drove a severe decline, and it may be possibly extinct, though occasional unconfirmed reports persist.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats between perches
Social Behavior
Typically found singly or in pairs, maintaining territories in dense low vegetation. Nests are neat cups woven from grasses and fibers, placed low in shrubs or reeds. Clutches are small, and both parents participate in feeding the young.
Migratory Pattern
Resident
Song Description
The song is a loud, varied warble interspersed with harsh scolding notes and squeaks. Males sing from exposed perches at dawn and throughout the day, switching to sharper calls when alarmed.
