Those of interest. This is undoubtly a complex dynamic issue. Please note
however that many species of "collared doves" are found in captivity and likely
the source of these feral populations. Aviculturalists do not often follow the
AOU! In fact often have their own names for species. In other cases the AOU
does not deal with the species as they are only a New World group. Fred will
know this from his experience with psittacines. My point is when dealing with
birds that are abundant in captivity one should always look at Avicultural and
Ornithological material and do not be surprised with you find conflicts!
Just another point to ponder!!

I have been privately corresponding with Brush about these doves, but see this
needs some wider discussion, as this is contrary to the AOU re: 47th Supplement
to the Checklist
(http://www.aou.org/checklist/suppl/AOU_checklist_suppl_47.pdf) which states as
follows:
p. 221. The name Streptopelia risoria is applied to a long-domesticated (often
feral) form of S.
roseogrisea (Goodwin 1983, Sibley and Monroe 1990, Baptista et al. 1997). We
follow these
authors in using the name of the wild species (roseogrisea) in place of the
name based on
domesticated birds. This follows the principle set forth in Opinion 2027 of the
International
Commission on Zoological Nomenclature (2003) that conserved the usage of
specific
names based on wild species of mammals that are predated by or contemporary
with
names based on domesticated forms. In the citation for the generic name
Streptopelia, add
to the designation of the type species “= Columba roseogrisea Sundevall.”
Replace the account of S. risoria with the following account:
Streptopelia roseogrisea (Sundevall). African Collared-Dove.
Columbam roseogriseam (accusative case) Sundevall, 1857, Kongl. Sv. Vet.-Akad,
Handl.
(n.s.) no. 1, art. 3, p. 54. (Nubia.) Habitat.—Arid country with trees and
shrubs,
often near human habitation. Feral populations occur mainly in urban and
suburban parks.
Distribution.—Resident in northeastern Africa and southwestern Arabia.
Introduced and established as feral populations of domesticated stock in
west-central
Florida (Pinellas County), the Bahamas (New Providence), and Puerto Rico. Other
introduced
populations in North America have failed to become established.
Notes.—Also known as Ringed Turtle-Dove and Barbary Dove. The widely
domesticated
and locally introduced populations (Goodwin 1983) have been known as S. risoria
(Linnaeus,
1758). Present North American feral populations may be entirely human-dependent
and
not self-sustaining.
all my best,

Fred,Feral populations of the popular cagebird the Common Ringneck Dove
(Streptopelia risora) do exist but are usually not large. One of the reasons
for this is that they often produce white mutations with are often the
preferred meal of raptors! This species is quite distinct from the African
Collared Dove (w/ Two races recognized: S. roseogrisea roseogrisea ; S. r.
arabica . Populations west of Lake Chad sometimes awarded separate race, S. r.
bornuensis) and the Eurasian Collared Dove (Two races recognized: S. decaocto
decaocto; S. d. xanthocylus - has a yellow eye cere instead of the whitish grey
eye cere color of the nominate race)
These are only three of a number of
collared doves throughout the World. Identification can be tricky although I
suspect the article mentioned by Brush should likely be the first place to
look. The Common Ringnecked Doves produces over 37 phenotypic variations!!To
compound identification challenges all the Streptopelia seem to hybridize
readily. If Eurasian Collared Doves were near a feral population of Common
Ringneck Doves I do not doubt you would see hybrids. I addition in order to
achieve a "wild type" Common Ringneck Dove breeders often hybridize
them with pure African Collared Doves.
Individuals interested in Streptopelia are encouraged to investigate John
Pire's International Dove Society webpage. John has been Texas's premier exotic
dove breederfor many years now. The site has numerous photos of all the seed
and fruit eating doves.
John has a great discussion of the matter
