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.
Nicobar Scrubfowl
A medium-sized megapode (~840 g) of family Megapodiidae, endemic to the Nicobar Islands of India in the eastern Indian Ocean. Inhabits dense coastal and inland forests, burying eggs in communal mounds of soil and leaf litter warmed by solar heat. Omnivorous, foraging for seeds and invertebrates. Vulnerable due to island endemism, habitat clearance, and tsunami impacts.
