SYNONYMS OR RELATED TERMS: mound builder, incubator bird
DEFINITION: A member of a family of stocky, chickenlike birds (order Galliformes, family Megapodiidae) found in Australia and the islands of the southwestern Pacific that build huge mounds of decaying vegetable matter in which to incubate their eggs. Most of the 12 species rely on fermenting plant matter to produce heat for incubation, but some use solar heat and others the heat produced by volcanic action.
