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.
Tanimbar Scrubfowl
A medium-sized megapode (~990 g) of family Megapodiidae, restricted to the Tanimbar Islands in the Banda Sea of eastern Indonesia. Inhabits coastal and hill forests, building mound nests for solar incubation of eggs. Feeds on fallen fruits, seeds, and invertebrates on the forest floor. Vulnerable due to small island range, deforestation, and sustained egg collection pressure.
