While Birdlife International splits this into Grey-breasted Green-Pigeon & African Green-Pigeon, I believe iNat follows Clements and lumps the taxa. This subspecies: https://www.inaturalist.org/taxa/625970-Treron-calvus-delalandii is the one that is a full species. The issue, some of these are from inland Zimbabwe which should be one of the two subspecies of the African Green-pigeon that ISN’T split here: http://datazone.birdlife.org/species/factsheet/grey-breasted-green-pigeon-treron-delalandii vs http://datazone.birdlife.org/species/factsheet/african-green-pigeon-treron-calvus . Note the distributions. I looked through the descriptions for Clements:
Treron calvus | |
---|---|
Treron calvus [calvus Group] | |
Treron calvus nudirostris | Senegal to Gambia and Guinea-Bissau |
Treron calvus sharpei | Sierra Leone to s Nigeria and n Cameroon |
Treron calvus calvus | eastern Nigeria to northeastern Democratic Republic of the Congo and central Angola |
Treron calvus poensis | Bioko I. (Gulf of Guinea) |
Treron calvus virescens | Principe Island (Gulf of Guinea) |
Treron calvus uellensis | South Sudan, northern Democratic Republic of the Congo, and Uganda |
Treron calvus brevicera | SW Ethiopia to n Tanzania e of Rift Valley (except for coast) |
Treron calvus salvadorii | eastern Democratic Republic of the Congo, southwestern Tanzania, Zambia, northern Malawi, and Mozambique |
Treron calvus gibberifrons | southeastern South Sudan south to the Lake Victoria Basin in Uganda, Rwanda, Burundi, western Kenya, and northwestern Tanzania |
Treron calvus wakefieldii | coastal Kenya and northeastern Tanzania |
Treron calvus schalowi | eastern Angola, northeastern Namibia, northern Botswana, and northwestern Zimbabwe |
Treron calvus ansorgei | W Angola (south of Cuanza River) |
Treron calvus vylderi | NW Namibia (east to Grootfontein) |
Treron calvus delalandii/granti | |
Treron calvus granti | Lowlands of e Tanzania and Zanzibar |
Treron calvus delalandii | coast from southeastern Tanzania south to South Africa (Eastern Cape Province) |
none of the mention Zimbabwe or Northern South Africa, only Western Zim. Roberts 7 gives that subspecies as T. c. glauca, which isn’t on that list at all? Avibase lumps this with T. c. delalandii which is inconsistent with the Birdlife International distributions…
Long Story short, anyone know what the Southern African plateau African Green-pigeons should be logged as?
