About These Birds
New Guinea Scrubfowl
A medium-sized megapode (~650 g) of family Megapodiidae, found in lowland and foothill forests of northern and western New Guinea. Constructs large mound nests of decomposing litter and soil for thermally regulated incubation of eggs. Forages on the forest floor for seeds, fruits, and invertebrates. Least Concern; broadly distributed but dependent on intact forest habitats.
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.
