I went to have a look at a rare bird reported in the Grimsby, Ontario area, a Eurasian Collared-Dove. It is an introduced species in North America, with the initial release in the Bahamas in the mid-70s. It has established itself on the mainland of the North American continent and is spreading across the continent. While still a rare bird in Ontario, there will probably come a time when it it much more common.
This is an old trick for this bird, in the 90s it rapidly established itself over much of Europe from its probably historical roots in India.
