This bird was reported be common until middle nineteenth century, but it declined before 1885 and thought extinct early this century. A small population persisted in rugged interior Rarotonga; 1987 stood at 38 birds decline. We determined that introduced predators, especially ship rats (Rattus rattus), were affecting breeding success. Through a program experimental management, aimed mainly rodent control, increased from low 29 Spring 1989 60 1993. recovery can attributed both improved success adult survivorship.
