Noble megapode Noble megapode The noble megapode ("Megavitiornis altirostris"), also known as the deep-billed megapode, is an extinct, flightless, giant stem-galliform bird that was endemic to Fiji. Originally thought to be a megapode, more recent morphological studies indicate a close relationship with "Sylviornis", in a clade outside of the Galliformes crown group. It is likely that it became extinct through overhunting shortly after the colonisation of the Fiji Islands by humans. The genus is monotypic, with the generic name "Megavitiornis" derived from the Greek "mega" (great), "viti" (Fiji), and "ornis" (bird). The specific epithet "altirostris" comes from Latin "altus" (high or noble),
Tongan megapode in Polynesia. Similar extinctions occurred in Fiji and New Caledonia, which apparently had three species in prehistory. The species itself once had a more widespread distribution, occurring across most of Tonga, Samoa and Niue. The cause of all these extinctions and declines was the arrival of humans on the islands, and the associated predation on adults and particularly eggs, as well as predation by introduced species. On Niuafo'ou the small human population and remoteness of its habitat probably saved the species. The only megapode to survive human arrival in Western Polynesia, "the megapode nesting grounds were carefully controlled by the
