describes the bird as "A small, long-billed, long-tailed bird of dense tangled undergrowth in lowland forest. Has olive-green wings and tail, a pale belly, a gray back of the neck, a gray back, and a gray chest with streaks. Note rufous cap and orange legs. Somewhat similar to leaf-warblers, but has a longer bill and a rufous cap. Song consists of a medium-pitched, whistled melody, 'plik-wod plick-wee,' sometimes given in duet. Also gives downslurred nasal scolds."

Ecology and behavior
It is known to feed on small invertebrates and is usually seen foraging in dense undergrowth, typically in pairs. The breeding season is believed to be at least from March to May. Their nest is typically placed 2 to 10 meters above the ground on the tip of a branch or leaf of a fern. Like all tailorbirds, the nest is complex and sown together to form a pouch. Two to three eggs are laid.Habitat and conservation status
It lives in lowland forest edges and clearings and also agricultural land and in secondary growth with tangled undergrowth. They are found mostly below 600 meters above sea level.IUCN Red List
