Pampusana
Pacific ground-doves, heavily impacted by extinction since the 18th century.
Pampusana is a genus of medium-sized, ground-dwelling doves within the family Columbidae. It includes 13 species that live in Pacific rainforests. These birds are not closely related to the American ground doves of the genus Columbina. The genus was originally named Alopecoenas in 1899, but the earlier name Pampusana, from 1855, takes priority. Some researchers consider Pampusana a very small subfamily, but current evidence places it within a basal radiation of Columbidae that includes many small, unusual lineages, such as Goura and Otidiphaps (which ecologically resemble Galliformes) and possibly the dodo and its relatives (Raphinae). About 10 species of Pampusana are still alive today. Among the larger dove genera, Pampusana has been hit hardest by extinction: three to four species have vanished since the 1700s, and most of the remaining species are declining, threatened, or have lost subspecies due to habitat destruction, invasive species, or overhunting. Several additional species are known only from subfossil bones and went extinct in the prehistoric Southern Pacific, between roughly 13000 BC and 1400 BC. The bones of Pampusana are distinctive enough to identify the genus easily, but the evolutionary relationships of extinct species are often unclear. Many now-extinct Polynesian forms once lived where the white-headed lineage (including P. jobiensis and P. erythroptera) and the Melanesian expansion (which produced P. sanctaecrucis and P. stairi, and possibly P. rubescens) would have overlapped. These ground-doves were moved out of the non-monophyletic genus Gallicolumba and reassigned here. The genus contains 13 species, three of which went extinct in historical times: the Norfolk ground dove (P. norfolkensis, extinct around 1800), the Tanna ground dove (P. ferruginea, extinct in the late 18th to 19th century), and the thick-billed ground dove (P. salamonis, extinct in the mid-20th century). The remaining living species are the Wetar ground dove, white-breasted ground dove, white-fronted ground dove, Polynesian ground dove, white-throated ground dove, shy ground dove, Santa Cruz ground dove, Marquesan ground dove, bronze ground dove, and Palau ground dove. Four additional species are known only from prehistoric remains: the Rota ground dove, great ground dove, Henderson ground dove, and New Caledonian ground dove.

Lore & Background
The genus Pampusana was previously named Alopecoenas, but Pampusana has priority. These doves might be ranked as a very small subfamily, but available data suggests they are better considered part of a basal radiation of Columbidae that includes many small and often bizarre lineages, such as Goura and Otidiphaps (ecologically convergent to Galliformes) and possibly the didines (Raphinae). Currently about 10 species are extant. Of the larger genera of Columbidae, Pampusana is the one most affected by extinction: 3–4 species have disappeared since the 18th century, and most remaining are decreasing due to habitat destruction, invasive species, or overhunting. Several additional species are known only from subfossil bones, having become extinct during prehistory of the Southern Pacific region (c. 13000 BC – 1400 BC).
Reader's Guide
Pampusana holds significance as a genus that illustrates the vulnerability of island bird populations to human activity. Its high extinction rate—three historically extinct species and four prehistoric ones—highlights the impact of habitat destruction, invasive species, and overhunting in the Pacific region. The genus also contributes to understanding the basal radiation of Columbidae, as it may be related to other unusual lineages like Goura and Otidiphaps. The bones of Pampusana are distinct enough for easy recognition, yet the evolutionary affiliation of extinct species is often uncertain. The removal of these ground-doves from the non-monophyletic genus Gallicolumba and their reassignment to Pampusana reflects ongoing taxonomic refinement. The loss of subspecies and the decline of most remaining species underscore the ongoing conservation challenges faced by these doves.
