Megapodes - Mound-Builders

There’s a group of birds that lay their eggs underground — in geothermally heated burrows, or  warm sands, or even mounds of organic material warmed by the heat of decomposition. These megapodes or mound-builders — like this Australian Brushturkey — are found in Australia, New Guinea, and nearby islands. The male builds a mound and adjusts the amount of material to maintain a constant temperature. After a long incubation, the eggs hatch and the chicks claw their way to the surface. They never know their parents, but emerge fully feathered and capable of flying and feeding themselves.
