Maleo

The maleo (Macrocephalon maleo) is a large megapode and the only member of the monotypic genus Macrocephalon. The maleo is endemic to Sulawesi and the nearby smaller island of Buton in Indonesia. 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. Description The maleo ranges from long with blackish plumage, bare yellow facial skin, reddish-brown iris, reddish-orange beak, and rosy salmon underparts. The crown is ornamented with a prominent, bony, dark casque - which is the origin of its genus name Macrocephalon (from the Greek makros meaning "large" and kephalon meaning "head"). 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. Juvenile birds have largely brownish and paler heads with short blackish-brown crests and browner upper parts. Behaviour and ecology 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 lizards, reticulated pythons, wild pigs, 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.
