About These Birds
Sula Scrubfowl
A medium-sized megapode (~845 g) of family Megapodiidae, endemic to the Sula Islands of eastern Indonesia. Inhabits tropical forests and uses solar or geothermal heat to incubate eggs in communal mounds or buried in warm substrates. Feeds on seeds and invertebrates. Vulnerable due to its restricted island range, forest clearance, and collection of eggs for food.
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.
