Legend Overview
Field Identification
c. 18 cm. A slender brown reed-warbler with medium-length bill ; plumage highly variable, tending toward greyish and brownish colour morphs. Nominate race has whitish supercilium; generally grey-brown above, feathers often with fine dirty white margins, wings and tail slightly darker grey-brown but tipped with white; sometimes some white feathers scattered asymmetrically on wings, tail and/or head; whitish below; iris dark; upper mandible black, lower mandible pinkish; legs grey. Sexes similar. Juvenile unknown. Races differ mainly in measurements and, subtly, in shades of colour: <em>eremus</em> is larger than nominate, with much longer, downcurved bill , entire plumage heavily tinted with cinnamon; niauensis differs from nominate in being smaller, and almost lacking supercilium and the white feather margins of back; flavidus is larger than nominate, has upperparts slightly washed yellow, underparts strongly washed yellow; ravus differs from nominate in having underparts washed yellow.
Systematics History
Editor's Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.
Has sometimes been considered conspecific with A. caffer and A. mendanae, but the three show obvious morphological, behavioural and genetic differences. Recent study of morphology and DNA has recommended that races flavidus and ravus (both of which occur on low-lying atolls) be subsumed within nominate (1). Six subspecies recognized.Subspecies

Distribution
Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.
Habitat
Woodland and brush country on atolls and raised coral islands; occurs also in gardens, coconut (Cocos nucifera) plantations and Pandanus thickets.
Movement
Resident.
Diet and Foraging
Mainly insects, including beetles (Coleoptera), flies (Diptera), hymenopterans; also spiders (Araneae), molluscs, crustaceans, small lizards, and some plant material. Forages by hopping rapidly up and down branches, pecking small items from twigs and leaves; forages also on the ground. Sometimes catches insects in flight.
Sounds and Vocal Behavior
Call a low “chru”, frequently repeated. Song usually consists of the “chru” call followed by a short whistling phrase, “chr-peee-tu-tu-pee-wee”, then a pause before being repeated with different arrangement of whistling notes; similar to that of A. caffer, but less rich and less varied.
Breeding
Probably breeds throughout year, without distinct season. Territorial. Nest a deep cup of grass stems , twigs, long leaves and fine stems of vines, and coconut fibres, lined with delicate fibres and dry grasses, sometimes small green leaves, external diameter 9–13 cm, height 6–12 cm, internal diameter 5·5–8 cm, cup depth 3·5–4·5 cm, placed 1·5–10 m above ground in bush, among trailing vines or in tree (including coconut palm). Clutch 1–3 eggs; no information on incubation and nestling periods; both parents feed young.
Conservation Status
Not globally threatened. Restricted-range species: present in Tuamotu Archipelago EBA. Locally common. In 1999, recorded as frequent to uncommon on Tuanake, Hiti, Tahanea and Tepoto; estimated density on small island of Tepoto in that year was 3·1 birds/ha.
