The Eurasian Collared-Dove was accidentally introduced in 1974 to the Bahamas and shortly after Florida. It is currently increasing and spreading through the United States form the southeast.
The Eurasian Collared-Dove is a pale dusty brown, relieved by paler, grayer face, a narrow black half-collar on the hindneck, and a white terminal half to the black tail. It has an expanding range from Florida and the southeast of the United States. It has a habitat in suburbs, residential areas, farmland, wood edges, and open country. It feeds mostly on mostly seeds, some berries, and insects. It usually forages in flocks by walking on the ground and fluttery in branches of trees, or shrubs to take berries.
