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.
Vanuatu Scrubfowl
A medium-sized megapode (~770 g) of family Megapodiidae, endemic to the Vanuatu archipelago in the southwest Pacific. Inhabits coastal and inland tropical forests, using solar-heated volcanic soils or organic mounds for egg incubation. Omnivorous, foraging on the ground for seeds and invertebrates. Least Concern; utilizes the geothermal activity characteristic of Vanuatu's volcanic islands.
