The maleo Macrocephalon maleo (Megapodiidae; Galliformes) is a megapode, endemic to Sulawesi, Indonesia, that lays its eggs communally in geothermally or solar-heated soil. The majority of maleo nesting grounds are threatened to some degree and over one-third of known sites have been abandoned. Maleos are severely threatened by habitat degradation and uncontrolled egg-collecting. Hunting of adult birds is also contributing to their decline in some areas. Conservation measures implemented so far have not been sufficiently effective in preventing maleo population declines. In order to safeguard the maleo from further declines we recommend that the laws protecting the maleo and its habitat be strengthened as a matter of urgency and that long-term community conservation and environmental awareness projects be implemented. To achieve these goals we advocate the formation of a collaborative network of international NGOs, Indonesian conservationists, government departments and local communities.
