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.
Orange-footed Scrubfowl
A large megapode (~950 g) of family Megapodiidae, with striking orange feet and a dark plumage. Found in coastal and savanna forests of northern Australia and southern New Guinea. Builds enormous communal mound nests that may reach 4 m high, maintained by multiple birds over many years. Feeds on seeds and invertebrates. Least Concern; widespread in tropical northern Australia.
