Phylogeny: 

Taxonomy: Drymophila trivirgata Temminck, 1826, Timor. Distinctive races diadematus and bimaculatus have been proposed as comprising a separate species. (source: Handbook of the Birds of World)

Distribution: 

Subspecies and Distribution:

    * bimaculatus G. R. Gray, 1861 - Morotai, Halmahera and Bacan, in N Moluccas. * diadematus Salvadori, 1878 - Bisa I and Obi. * bernsteinii Salvadori, 1878 - Salawati I, in extreme NW New Guinea.
Habitat: 

Mostly dense primary foest and secondary tropical and subtropical forest, wooded gulleys and adjacent scrub. Gouldi in sclerophyll forest and occasionally in adjacent eucalypt forest, also mangroves, parks and gardens. From sea level to 300 m in Timor, 800 m in Seram.

Migration: 

Resident.

Trophic strategy: 

Food mostly small invertebrates, including ants, termites, beetles, cockroaches, spiders, moths, dipteran and orthopterans, also small snails. Solitary or in pairs, and in mixed-species foraging flocks. Middle strata of ofrst trees. Gleaning in foliage, especially in vines, creepers and behind loose bark.

Reproduction: 

Season mainly Sept-Feb (May), fledgling seen in Jul and Aug on Sumba. Territorial, male vigorously defends territory against rivals. Contact between partners-fluffing-out of body feather. Nesc cup-shaped, conical and made of fine bark strips, plant fibres, grasses, dry leaves, plant down, moss lichens and gossamer, placed up to 6 m above ground in vertical fork of shrub, tree.
