Alopecoenas nui (Steadman)

Giant Ground Dove (Alopecoenas nui)

The Giant Ground Dove is known only from subfossil bones which were found on the islands of Mangaia, Cook Islands; Kamaka, Gambier Islands; Hiva Oa, Tahuata and Ua Huka, Marquesas as well as Huahine, Society Islands.

The species was sympatric on the Cook-, Gambier- and Society Islands with the smaller Polynesian Ground Dove (Alopecoenas erythroptera (Gmelin)) and on the Marquesan Islands with the Marquesas Ground Dove (Alopecoenas rubescens (Vieillot)), and perhaps with additional, yet extinct species.

The Giant Ground Dove was no true giant, but was still larger than all its Polynesian congeners, reaching a size of about 36 cm.
