Eurasian Collared Dove

The Collared Dove was introduced into the Bahamas in the 1970s and spread from there to Florida by 1982. It has become invasive;[8] the stronghold in North America is still the Gulf Coast, but it is now found as far south as Veracruz, as far west as California, and as far north as Alaska, the Great Lakes, and Nova Scotia. Some of the more distantly dispersed records may refer to local escapes from captivity.[6] Its impact on other species there is as yet unknown; it appears to occupy an ecological niche between that of the Mourning Dove and the Rock Pigeon (also an invasive species in North America).
