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.
Tongan Scrubfowl
A small megapode (~375 g) of family Megapodiidae, restricted to Niuafo'ou Island in the Kingdom of Tonga. Inhabits the island's forest edges and volcanic crater areas, using geothermal heat to incubate communally buried eggs. Feeds on seeds and invertebrates. Vulnerable; entire global population limited to a single small volcanic island with periodic eruption risk.
