Megapode the surface of the mound, lying on their backs and scratching at the sand and vegetable matter. Similar to other superprecocial birds, they hatch fully feathered and active, already able to fly and live independently from their parents. In megapodes superprecociality apparently evolved secondarily from brooding and at least loose parental care as more typical in Galliformes, but their reproductive model has been compared to various extinct maniraptors, implying that supreprecociality was common if not ancestral in early birds. Eggs previously assigned to "Genyornis" have been reassigned to giant megapode species. Some dietary and chronological data previously assigned to dromornithids
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
