SUBSPECIES

S coast of SE New Guinea (Angabunga R E to Yeimauri R area).

Distribution

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Habitat

Rainforest, monsoon forest, nearby tall secondary growth and swamp-forest; lowlands to c. 650 m, locally to 850 m. Found mainly in interior of forest, sometimes at edge.

Movement

Sedentary; individuals observed or recaptured for up to 3 years at same locality.

Diet and Foraging

Insects. Forages from near ground level to below canopy, but mostly in lower to middle levels. Food obtained by gleaning, flycatching-gleaning and flycatching; proportions of each technique vary, from mainly flycatching (c. 80%) to little flycatching (less than 1%), and to mostly gleaning; gleans from outer to middle part of tree, from leaves (74%), leaf litter (12%), branches (10%), trunks (4%). May join mixed-species foraging flocks of small insectivorous passerines.

Sounds and Vocal Behavior

Song 3 rising whistled notes, each one tone higher than previous, and 3–5 (sometimes 8) high-pitched descending notes, with final note sometimes rising; varies geographically. Other vocalizations include short decelerating trill for scolding, high-pitched nasal “chicew”, and weak “chip” as contact.

Breeding

Nest with eggs in Jul, recently fledged young in early Oct, fledglings in late Aug, birds in breeding condition May–Aug (testes enlarged Jul), and paired adults observed late May to early Oct; apparently breeding during dry season. During what appeared to be courtship behaviour (in Jul), one individual occasionally hovered over the other. Nest a small cup with “tail” hanging from underside; placed 0·4–0·9 m from ground on thin horizontal fork in small, slender shrub several centimetres from main vertical stem, in fairly open area in forest substage. Clutch 2 eggs, pinkish-white, with sparse reddish-brown spots mainly at large end; no information on incubation and fledging periods.
Not globally threatened. Generally very common to fairly common in lowlands, less so in hills. Estimated density of 6 birds/10 ha at lowland rainforest site near R Brown, in SE New Guinea.
