"The Pacific Emerald Dove is the name for birds that occur on mainland Aus and
the Pacific Islands. In Aus territory, Indian Emerald Dove occurs only on
Christmas Island
Pacific Koel is the bird on the mainland and has been recorded at Ashmore Reef.
Asian Koel is now regular on Christmas and Cocos so keep a look out for it in
the NW."

"Hi Mick,
You reminded me of something odd about the Emerald Dove split that I had
forgotten to look into, does the Pacific Emerald Dove have the right species
name. The splitting of Emerald Dove in 2 gives us Pacific Emerald Dove
Chalcophaps longirostis. HANZAB lisats the east coast subspecies as
chrysochlora, which is an older name (1827) than longirsotris (1842). Under the
rules of nomenclature the species should take the name of the oldest valid
subspecies, so unless there is something wrong with chrysochlora it should be
the Pacific Emerald Dove Chalcophaps chrysochlora. Christidis & Boles did not
split the emerald doves but they indicated that if they were split the one in
Australia would be C. chrysochlora. However, it seems that chrysochlora must be
invalid, rogersi Mathews 1912 is the subspecies in the east, and longirostris
is the species name after all.
This is how the IOC classify the emerald doves
Chalcophaps indica Common Emerald Dove
C.i.indica
C.i.robinsoni
C.i.maxima
C.i.augusta
C.i.natalis
C.i.minima
C.longirostris Pacific Emerald Dove
C.l.timorensis
C. l. longirostris
C.l.rogersi
C.l.sandwichensis
C.stephani Stephan's Emerald Dove
C. s. wallacei
C.s.stephani
C.s.mortoni

Subject: Emerald Dove RFI: Pacific or Common?
Hi Birders,
There appear to be inconsistencies in the naming of Pacific Emerald Dove and
Common Emerald Dove. At least some birders have adopted the name Pacific
(Chalcophaps longirostris) for birds from eastern Australia and Lord Howe
Island etc, and Common (Chalcophaps indica) for birds from the Top End. This
would seem to be a logical thing to do. However, according to both bird
guide books Pizzey & Knight and Simpson & Day, the former race longirostris
applies to birds from the Top End. If so, the abovementioned naming practice
would seem to be back to front.
So, has someone got something wrong? Was it the guide books, who some years
ago incorrectly reversed the locations of the 2 dove races? Or was it the
IOC, who accidentally ascribed the names Pacific and Common to the wrong
species? Certainly, the name Pacific should logically apply to the species
that inhabits the Pacific coast of Australia and adjacent islands.
A summary of some public information is set out below:
P&K; S&D
Chalcophaps indica - race rogersi (formerly chrysochlora) - eastern
Australia, Lord Howe Is - picture shows plain green back.
Chalcophaps indica - race longirostris - Kimberley & Top End - picture shows
grey & white bars on back.
IOC Checklist 3.1
4859. Common Emerald Dove - Chalcophaps indica - OR, AU - widespread.
4866. Pacific Emerald Dove - Chalcophaps longirostris - AU - Australasia.
Birding for Devils
366 - 14 Feb - Common Emerald Dove - Christmas Island
130 - 19 Jan - Pacific Emerald Dove - Lake Eacham, Qld
M Roderick on B.Aus
re: Emerald Doves, but as far as I understand it C. indica ("Common") occurs
in the Top End and Kimberley and this species also ranges into SE Asia.
whereas C. longirostris ("Pacific") is the one found on the East Coast of
Australia and Pacific Islands (including Lord Howe). C. natalis (from
Christmas Island) is retained as a subspecies of (presumably) C. indica.
Hoping that someone out there can bring all this to the attention of those
in power.

If I could tick both species I wouldn't be so concerned, but as I can only
tick one, I do need to know which one.
