The maleo (Macrocephalon maleo) is a large megapode and the only member of the monotypic genus Macrocephalon. The maleo is endemic to the Indonesian island of Sulawesi. It is found in the tropical lowland and hill forests, but nests in the open sandy areas, volcanic soils or beaches that are heated by the sun or geothermal energy for incubation.
The maleo ranges from 55–60 cm long with blackish plumage, bare yellow facial skin, reddish-brown iris, reddish-orange beak and rosy salmon underparts. The crown is ornamented with a black helmet casque. The greyish blue feet have four long sharp claws, separated by a membranous web. The sexes are almost identical with a slightly smaller and duller female. Juveniles have largely brownish and paler heads with short blackish-brown crests and browner upperparts.
The maleo's egg is large, about five times as large as that of the domestic chicken's. The female lays and covers each egg in a deep hole in the sand and allows the incubation to take place through solar or volcanic heating. After the eggs hatch, the young birds work their way up through the sand and hide in the forest. The young birds are able to fly and are totally independent. They must find food and defend themselves from predators such as monitor lizard, reticulated python, wild pig and cats.
The maleo is monogamous, and members of a pair stay close to each other all the time. Its diet consists mainly of fruits, seeds, mollusks, ants, termites, beetles and other small invertebrates.
