Size: 

12.5- 14 cm; 19- 22 g

Phylogeny: 

Taxonomy: Eulacestoma nigropectus De Vis, 1894, Mount Maneao, south-east New Guinea. Affinities uncertain. A recent proposal separates present genus and Falcunculus in a narrow family Falcunculidae. Proposed race clara, from C ranges (Weyland Mts E to Mt Hagen and Kubor Mts), considered inseparable from populations elsewhere. Monotypic. (source: Handbook of the Birds of World)

Distribution: 

Distribution:

    C & E New Guinea from Weyland Mts E to mountains of SE.
Habitat: 

Forest and adjoining areas with dense regrowth, mainly at 1950- 2850 m, locally down to 1250 m in SE. Frequents substage and midstage, particularly thickest of climbing bamboo.

Trophic strategy: 

Insects. Forages from understorey to middle stage, to c. 10 m, particularly in thickest of climbing bamboo. Gleans prey from surfaces of branches and twigs , especially broken tips when these dead and dry; removes bark by chipping and stripping, digs forcefully in bark and moss. Will lean with head downwards over limb to examine underside for prey. Often joins mixed-species feeding flocks.

Reproduction: 

Juveniles in May and late Jun and female in breeding condition in Jul, indicative of breeding during both wet and dry seasons. Incubation by male reported; role of female unknown, but presumably shares duty. No other information. NoT.
