Pile-builder megapode ulna, a distal left ulna, a distal-end left ulna proximal, and a half right femur. When the early settlers of the Lapita culture arrived in Tonga around 1500 BC, they found only marine species such as sea turtles and giant forms of terrestrial birds such as megapodes, doves, and rails. The hunting of these bird species for food led to their rapid extinction. In New Caledonia, the giant megapode might have survived into historic times. William Anderson, a naturalist and surgeon's mate aboard during James Cook's second South Sea voyage, described a bird from New Caledonia with bare legs, which
Micronesian megapode the multiple threats across its range, it is likely to be suffering from a continuing decline. It seems that the only way for the species to be safe is to protect a few small islands and release a small population of megapodes there. That way, a safe population is secured. On the larger and higher islands, an increase of people and introduced pests will sooner or later destroy any megapode populations. The Marianas Island megapode or "Megapodius laperouse laperouse" is the nominate subspecies of the Micronesian megapode found in the Mariana Islands. It is rare, localised and in danger of
