The family Megapodiidae, commonly known as megapodes or mound-builders, consists of large, ground-dwelling birds found primarily in Australia, New Guinea, and surrounding islands. These birds are unique for their reproductive strategy, where they build large mounds of decaying vegetation to incubate their eggs using the heat generated from decomposition. Megapodes are known for their strong legs and ability to run quickly. They have a distinctive appearance, often featuring a robust body and a short tail. Unlike many other birds, megapodes do not sit on their eggs; instead, they rely on the warmth of the mounds to ensure successful hatching.
