Sexes similar. Immature with brownish crown and without dark streaks on underparts.
Distribution
Found on New Guinea and some adjacent islands.
Uncommon but widespread. An unobtrusive species, occuring in rather low density.

- S. s. granti in western New Guinea (Snow Mountains)
- S. s. wuroi in southern New Guinea (Trans-Fly lowlands)
- S. s. guttatus in the mountains of southeast New Guinea
- S. s. ferrugineus on Waigeo Island (New Guinea)
- S. s. aruensis on Aru Islands (New Guinea)
- S. s. batantae on Batanta Island (New Guinea)
Habitat
Mostly in hill forest from 200 to 1200 m. Also in lowland forest in Trans-Fly lowlands and northern New Guinea. Replaced at higher eleveations by Large Scrubwren. Overlaps with Grey-green Scrubwren and with Tropical Scrubwren in parts of its range.

Diet
Not well known. Feeds mostly on insects.
Forages low in understorey up to middle level. Flicks often with its tail and gleans prey actively from leaves, twigs and branches. Sometimes in mixed-species flocks together with Yellow-bellied Gerygone, Chestnut-bellied Fantail, Spot-winged Monarch, Frilled Monarch, Wallace's Fairywren and Hooded Pitohui.
