Produces a loud, repeated booming call and guttural clucking notes. The deep, far-carrying boom is the key territorial sound; diagnostic in semi-arid Australian mallee scrubland.
Biak Scrubfowl
Produces a loud, wailing cackle and guttural clucks. Calls are consistent with other Pacific Megapodius scrubfowl; heard on Biak and Numfoor islands at dusk and dawn.

About These Birds
Malleefowl
A large megapode (~2.1 kg) of family Megapodiidae, cryptically patterned in brown, black, and white. Endemic to arid and semi-arid mallee scrublands of southern Australia. Males build enormous soil-and-litter mounds, monitoring internal temperature with the bill and adjusting insulation year-round. Feeds on seeds and invertebrates. Vulnerable due to land clearing and introduced predators.
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.
