Talpanas lippa, the Kauaʻi mole duck, is an extinct species of duck. It was first described by Andrew N. Iwaniuk, Storrs L. Olson, and Helen F. James in the journal Zootaxa in November 2009. It is the only known member of the genus Talpanas. It was endemic to the Hawaiian island of Kauaʻi where the fossil remains were unearthed in the Makauwahi Cave, Maha‘ulepu. The archaeological association of the bones is about 6000 years BP (around 4050 BCE).

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.
