A good example of a Pharoah Breed of Coturnix coturnix quail

The quails that I mentioned, Coturnix coturnix, all have some commercial value somewhere in the world for hunting, eggs, meat and research purposes, whereas Button and Chinese quails are purely decorative and known by a different name everywhere. All quails are called different names in different parts of the world and as soon as money gets involved, the facts are starting to be distorted, but we cannot create species at will. Hence there is no such species of animal as a Coturnix japonica. Mediterranean quails, Coturnix coturnix, roam freely in the Mediterranean. I have an estate in the Po Valley in Italy where Coturnix coturnix are abundant still today. The “problem” with Coturnix coturnix is that it is such an adaptable animal in captivity with such great production capacities and very short generation intervals that it is being favoured all over the world by researchers and commercial producers alike. These Mediterranean birds migrate over to North Africa every year and the Egyptian Pharaohs have caught and domesticated them many hundreds of years ago. Some time later the Japanese Emperors purchased some from the Pharaohs for their song apparently – which is just another nonsense as Coturnix coturnix does not have any singing sound and would probably be the last bird you would acquired for such.  Because of the special qualities of Coturnix coturnix they were and are being kept in every corner of the world and as such various mutations happened over the years and combined with selective breeding, new breeds have evolved (Tibetans, Golden Italians, Whites, Etc, Etc), but no new species has sprung up from somewhere. As an example the latest meat Ross and Cobb chickens are different breeds, but still Gallus gallus, not a new species. Similarly Jumbo, White, Golden Italian, Tibetans, Common quails, call them what you like, are different BREEDS, but not different SPECIES – still Coturnix coturnix. Similarly an Alsation, Bulldog, Greyhound and Chihauhau are all different breeds of dogs and not different species of animals and all are Canis lupus https://backyardfarmer.co.nz/quails/

As soon as money gets involved people make all sorts of claims for personal benefit

Do not believe everything you read on Wikepedia either

In New Zealand, the problem is that as result of legislation, no new Coturnix coturnix have entered the country for many decades, resulting that ALL Coturnix coturnix in NZ being related, inbred and mongrels with poor production capacities compared to birds in other parts of the world (Maybe we must apply for a Coturnix newzealandia nomenclature for an exceptionally poor example of the species) The problem with the breed in New Zealand is that there is no overseeing controlling body that monitors matters and every person with a male and a female call themselves “breeders”, whereas they are just multipliers doing more harm than good to the species. As a qualified geneticist (retired) I am, as a hobby, trying to breed a better Coturnix coturnix in New Zealand and have achieved good results over the 10 years that I lived in New Zealand

There is no such species of animal as a Coturnix japonica or Japanese Quails
