Erromango Imperial Pigeon (Ducula sp.)
This taxon is known from subfossil remains that were found on the island of Erromango, Vanuatu and apparently cannot be assigned to any of the congeneric forms found on that island today and may thus in fact constitute an extinct species.

Erromango Starling (Aplonis sp.)
The Erromango Starling is known from subfossil remains found on the island of Erromango, Vanuatu, which apparently cannot be assigned to one of the starling species that inhabit Vanuatu today, the Mountain Starling (Aplonis santovestris Harrison & Marshall), and the Rusty-winged starling (Aplonis zelandica (Quoy & Gaimard)).
This form apparently disappeared sometime after the arrival of humans onto the island. [1]
