About These Birds
Dusky Scrubfowl
A medium-sized megapode (~645 g) of family Megapodiidae, occurring across the Maluku Islands and western New Guinea. Inhabits coastal and lowland forests, constructing large communal mound nests of soil and organic debris for egg incubation. Forages on fallen fruits, seeds, and invertebrates. Least Concern with relatively wide distribution across the Wallacea region.
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.
