It is cream with small reddish spots; and measures 36 x 27 mm in the Marquesas 41 x 29 mm in Rapa. Incubation lasts 50 days and 60 days in the Gambier.

Status and protection

The species is listed in category A of the list of species protected by the territorial regulations of French Polynesia.
It is classified “Endangered” (EN) on the IUCN Red List because many known breeding sites have been abandoned in the last 50 years. It nests only in islands where cats and big rats are absent. Even the small Polynesian rat could have a negative impact on this species.
