Produces a loud, raucous cackling call and guttural clucking notes. The wailing, repetitive cackle is the standard Megapodius call; echoes through Micronesian island forest at dusk.
Tongan Scrubfowl
Emits a loud, cackling wail and guttural territorial calls. Vocalizations poorly known; presumed to produce typical Megapodius scrubfowl cackling-wail calls on Tongan islands.
Geographic Range & Migration
Micronesian Scrubfowl
Endemic to Palau and the Mariana Islands in Micronesia. Found in lowland forest and scrub on volcanic and limestone islands.
Tongan Scrubfowl
Endemic to Niuafo'ou Island in Tonga. Found in tropical scrub and forest. Critically endangered, with a tiny population on one island.

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.
