The orange-footed megapode is a chicken-sized, ground-living bird with dark plumage, powerful orange legs and a pointed crest at the back of its head. Its strong feet rake through leaf litter while it searches for seeds, fallen fruit and terrestrial invertebrates. The species occurs across numerous islands of the Lesser Sundas and also in southern New Guinea and northern Australia; its island populations have been divided into several named forms (Wikipedia general species account).
Instead of warming its eggs by sitting on them, a pair builds and maintains a mound of sand, leaves and other organic debris. Heat released as the plant material decomposes incubates eggs buried within the structure. Active mounds may reach 4.5 m high and 9 m across, and maintenance continues through the year. This unusual system leaves the developing chick dependent on mound temperature rather than direct parental brooding (Wikipedia general species account, drawing on the cited megapode literature).
