Recording by Philippe Raust:
Varied, especially insects. Like all French Polynesian Reed-warblers, it hunts both on the ground and in trees and shrubs, which is unusual for the genus. This reflects an adaptation to island lifestyles where birds tend to occupy several ecological niches rather than specialize and frequent only one type of habitat as is often the case for continental species.
One to three light blue-green eggs (23 x 16 mm) with dots and brown spots concentrated on the broadest side. Nests probably all year long.
