Most birds incubate their eggs with body heat, but not megapodes, a chicken-sized bird with heavy body, short rounded wings and large, strong, four-toed feet. Birds in this family bury their eggs in soil and incubate them using natural heat sources. Depending on the species and its location, megapodes may lay their eggs in burrows dug in sun-warmed beaches, or geothermally active areas, or they may build large incubation mounds and fill them with organic matter such as leaves, and derive heat through their decomposition.
