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.
Micronesian Scrubfowl
A small megapode (~340 g) of family Megapodiidae, occurring on the Mariana and Palau Islands of Micronesia. Inhabits coastal and interior forests, burying eggs in warm sand or volcanic soil for solar incubation. Feeds on seeds, fruits, and invertebrates. Near Threatened; populations reduced by habitat loss, introduced predators (rats and pigs), and historically by collection.
