East Asian Treron Nomenclature (1 Viewer)

[petemorris]

I've been re-ordering and updating some of our East Asian checklists at work, following the publication of Birds of East Asia, Brazil, 2009. In it he has split Whistling Green Pigeon into Taiwan Green Pigeon (T. formosae including filipinus) and Ryukyu Green Pigeon (T. riukiuensis including permagnus and medioximus). I've no problem with the split, but where did riukiuensis come from? Surely Ryukyu Green Pigeon should be T. permagnus, or am I missing something??:-C

Hi,

Check out this thread for a discussion on riukiuensis:

Oops, thanks!:t:

IOC have Treron phayrei (Blyth, 1862) with two subspecies:
*T. p. phayrei (Blyth, 1862): ne India through Myanmar to sw China and s Indochina
*T. p. conoveri Rand & Fleming, 1953: Nepal

But there also appears to be a Treron nepalensis Blyth ex Hodgson (pic from Bonaparte, 1857), which from the name is presumably also from Nepal - is T. p. conoveri a synonym of this earlier name? Or is it an invalid name, or something different altogether?

There's a lot of pages on the web which use that name. But this one: https://m.wallace.biodiversity.online/species/A-Vert-Aves-000247 has pictures of specimens which were collected by A. R. Wallace under that name in Sumatra (not Nepal!) and it classifies them as T. curvirostra curvirostra.

Toria nipalensis Hodgson 1836 (https://www.biodiversitylibrary.org/page/43118057) is the Nepal ssp of Treron curvirostra.

This Bonapartian plate is taken from https://www.biodiversitylibrary.org/page/47762800, and should in principle show this taxon. The red bill base, and flashy green orbital skin -- the latter hardly visible on the Wikipedia version, though -- are characters of curvirostra. Why is this bird called phayrei ?

Excellent, thanks! I'll correct the wiki commons file. This file is very low resolution (only 78 KB), which is why the detail doesn't show.

Looks like the erroneous attribution to phayrei came from worldbirdinfo.net (see the 2013 edit adding it); that link is dead now so I don't know what it said.
