The Eurasian Collared Dove, Streptopelia decaocto, is one of the great colonisers of the avian world. Its original range was warmer temperate regions from southeastern Europe to Japan. However, in the twentieth century it expanded across the rest of Europe, reaching as far west as Great Britain by 1953; breeding in Britain for the first time in 1956, and Ireland soon after. It also now breeds north of the Arctic Circle in Scandinavia. It is not migratory.
