The grey-green scrubwren is a species of bird in the family Acanthizidae. It is found in the highlands of New Guinea ; its natural habitat is subtropical or tropical montane forests.
Region
New Guinea Highlands
Typical Environment
Occurs along the central cordillera of New Guinea, including the Arfak and Vogelkop ranges in the west and the Owen Stanley Range in the east. It inhabits dense understory of montane and mossy cloud forests, forest edges, and secondary growth. Birds typically keep to shaded thickets, bamboo patches, and tangles near streams. It is generally sedentary within suitable habitat and can be locally common where understory is intact.

The grey-green scrubwren is a small New Guinea songbird formerly placed in Sericornis and now in Aethomyias following genetic studies. It forages quietly in dense undergrowth and often joins mixed-species flocks with other highland insectivores. Though subtly colored, its preference for mossy montane forest and thin, high calls help with identification.
Temperament
shy and skulking
Flight Pattern
short rapid wingbeats
Social Behavior
Usually seen singly, in pairs, or small family groups, and frequently joins mixed-species flocks in the understory. Nests are typically domed or globular structures placed low in dense vegetation. Territorial during the breeding season but tolerant in loose foraging flocks.
Migratory Pattern
Resident
Song Description
Song consists of thin, high-pitched trills and soft tinkling phrases delivered from low perches. Calls include sharp chips and scolding notes when disturbed.
Plumage
Olive-grey to grey-green upperparts with a greyer face and underparts; subtly mottled or washed flanks. Throat pale to whitish with faint streaking; wings and tail dusky with olive edging.
Diet
Feeds primarily on small arthropods such as insects, spiders, and their larvae gleaned from leaves, bark, and moss. It probes tangles, vine clusters, and bamboo for hidden prey. Occasionally takes small berries or other soft plant matter.
Preferred Environment
Forages in the shaded understory of montane and mossy forests, along forest edges, and in dense secondary growth. Often works near the ground up to mid-levels, especially in tangled vegetation and bamboo thickets.
