About These Birds
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.
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.
