Rainforest, monsoon forest, occasionally teak plantations and nearby open ground; usually in lowlands and lower hills, locally to 1200 m, rarely to 1500 m.



Insects caught in middle storey to understorey by shortdashes out from branch, aerial flycatching, gleaning and hovering. Occasionally joins mixed flocks for faraging.


June to August, egg-laying in southeast New Guinea (Port Moresby lowland) from May to November, and juvenile in early June. This suggests that breeding starts at the end of the wet season and continues throughout the dry season.
Nest consists of a small cup of moss, hair lined and bound up with cobwebs, at 1.5–12 m from ground on parallel branch of an isolated small tree. 2 eggs.


Songs consists of rapidly falling and rising dissyllabic and repetitive “uliuliuliuliuli”, a quiet whistled note repeated 3 times or more, a reprimanding babble of repeated grating nasal notes, also a rusty “swee”.


Non migratory.
