Characteristics

Present in many islands of the Marquesas, where it remains common (Nuku Hiva, Ua Huka, Ua Pou, Tahuata, Fatu Hiva, Mohotani) or rarer (Hatutu, Eiao, Hiva Oa). Despite an identical phenotype, it exists two species: A. percenis in the northern group of the Marquesas (except Ua Pou) and A. mendanae in the southern group of the Marquesas and Ua Pou.

The nests contain two to three pale blue eggs with blackish grey dots and on the wider side (24 x 15 mm). It is possible that the species breeds throughout the year, although it seems the young would for most of them, leave the nest around May and June on Ua Huka.

Gardens and wooded areas of the islands where it particularly likes dry areas. It is abundant, even at high altitude, including Nuku Hiva. Frequently hunting on the ground, which is unusual for the genus.

Melodious songs, “tululu”, “tri-tri-tri-tri” and “chrou”. The songs are less varied than those of the Tahiti Reed-warbler (Acrocephalus caffer).

Insects and lizards are the basis of his diet. Sometimes it eats plants.
