Megapode

A ground-dwelling bird in the family Megapodiidae that incubates its eggs using environmental heat, often from sunlight or decomposing vegetation.

Mound-building: The construction of a large nest mound from soil and decomposing plant material. Many megapodes bury eggs in mounds whose microbial decay supplies incubation heat.
Megapodiidae: A family of birds commonly called megapodes, native to Australasia and nearby islands. This family contains all birds classified as megapodes.
Australian brushturkey: A large megapode of eastern Australia that incubates eggs in substantial compost mounds. Its conspicuous communal mounds exemplify incubation by decomposing vegetation.
Megapode fossil record: The preserved remains of extinct megapodes and close relatives across geological time. Fossils document a wider past distribution than the family’s modern range.
Nest mound: A pile of soil and organic material used by some birds as a nesting site. The mound is a megapode’s heat-producing incubator, carefully adjusted by the male in many species.
Galliformes: An order of mostly ground-dwelling birds that includes chickens, turkeys, and pheasants. Megapodes belong to this broader bird order.
Malleefowl: An Australian megapode that breeds in large mounds and adjusts their temperature with sand. Its precise mound management shows how environmental incubation can be regulated.
Australasia: A geographic region encompassing Australia, New Zealand, and neighboring parts of the Pacific and Southeast Asia. Modern megapodes are concentrated in this broad region.
Thermal incubation: The development of embryos in eggs warmed by an external heat source. Megapode eggs develop using environmental warmth rather than the parent’s body heat.
Precociality: A developmental pattern in which young are relatively mobile and independent soon after hatching. Newly hatched megapodes can leave the nest and fend for themselves unusually quickly.
