Your thinking of the ring neck dove , They can not live in the wild and die pretty fast if turned lose.
Google the euro and you will see it island hopped over here and has spread like crazy,
Its a warm weather dove but seems to be adapting to the cold.
The Eurasian collared dove bred for the first time in Britain in 1955 in Norfolk. Before 1930 it was confined to Turkey and the Balkans in Europe, although it was found as far east as China. In the next 20 years, it rapidly expanded its range northwest, quickly colonising most of Europe, and now lives north of the Arctic circle in Norway and as far south as Morocco and the Canary Islands.
So collared doves have only lived and bred in the UK for a few decades, but they weren’t introduced – they spread to new areas on their own, as their young have a tendency to disperse far and wide.
Eurasian collared doves are an invasive, non-native species in North America, where they’re now widespread since a few dozen collared doves escaped from an enclosure in Bahamas in 1974. Their range expansion through the US was even faster than their spread across Europe.
