About These Birds
Dusky Scrubfowl
A medium-sized megapode (~645 g) of family Megapodiidae, occurring across the Maluku Islands and western New Guinea. Inhabits coastal and lowland forests, constructing large communal mound nests of soil and organic debris for egg incubation. Forages on fallen fruits, seeds, and invertebrates. Least Concern with relatively wide distribution across the Wallacea region.
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.
