How to Tell Them Apart
Biak Scrubfowl
Dull brownish with darker brown upperparts; bare reddish periorbital skin; small pale crest on forecrown; underparts grey-buff. Similar to Dusky Scrubfowl but restricted to Biak Island, with slightly paler flanks.
Yellow-legged Brushturkey
Plumage is dark brown to black; bare skin around face reddish, throat wattle yellow; legs and feet bright yellow, distinguishing it from allies. Wings faintly barred with paler brown.
About These Birds
Biak Scrubfowl
A medium-sized megapode (~525 g) of family Megapodiidae, endemic to the Biak-Supiori island group in Geelvink Bay, West Papua, Indonesia. Inhabits lowland forests and coastal vegetation. Builds mound nests warmed by solar heat for egg incubation. Forages for seeds and invertebrates. Near Threatened due to its very restricted island range and ongoing deforestation.
Yellow-legged Brushturkey
A medium-large megapode (~1.3 kg) of family Megapodiidae, identifiable by yellow legs and a dark bill. Inhabits lowland rainforests of southern New Guinea. Like other brushturkeys, it is a mound-builder that uses decomposing vegetation to incubate eggs. Feeds on fruits and invertebrates on the forest floor. Least Concern; relatively poorly studied species.
