About These Birds
New Guinea Scrubfowl
A medium-sized megapode (~650 g) of family Megapodiidae, found in lowland and foothill forests of northern and western New Guinea. Constructs large mound nests of decomposing litter and soil for thermally regulated incubation of eggs. Forages on the forest floor for seeds, fruits, and invertebrates. Least Concern; broadly distributed but dependent on intact forest habitats.
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.
