ID tip

A small warbler that occurs only on Nīhoa and Laysan in the Northwestern Hawaiian Islands. It is unlikely to be confused with any other species; the only other passerines on those islands are finches. It does not occur on the main Hawaiian Islands and prefers dense, low vegetation. It is usually secretive and hard to see well, but males sometimes sing from an exposed perch. The song and calls are harsh chirps and churring.
