Noble Megapode

Megavitiornis altirostris is an extinct, flightless, giant stem-galliform bird that was endemic to Fiji, it is the only known species in the genus Megavitiornis. Originally thought to be a megapode, more recent morphological studies indicate a close relationship with Sylviornis of New Caledonia, with both genera belonging to the family Sylviornithidae 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.

==Etymology== 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), and rostrum (bill), referring to the extraordinarily large vertical dimension of its bill. Worthy also suggested “Noble Megapode” would be an appropriate vernacular name for the bird.
