To see this bird outside of south west Spain and Portugal, you will have to travel about 9000kms to the Far East, China, Japan, Mongolia. A strange fact. It was thought that seamen, brought them back to Europe in the 15th C., but a specimen found recently in Gibralter put its age at 40,000 years. So the current theory is that they were separated during an ice age. The species name Cyanopica cyanus covers all Azure-winged Magpies from East to West, but while some geneticists believe that the Spanish population is a sub species with a name of Cyanopica cooki, Birdlife International do not believe the DNA case is strong enough to warrant sub-species status. I have gone with the sub-species name to link it to where I have seen (Extremadura, Spain) and photographed it.
