edit: lol, some people are crazy.
Although there are approximately 200 million starlings in North America, they are all descendants of approximately 60 birds (or 100 [1]) released in 1890 in Central Park, New York, by Eugene Schieffelin, who was a member of the Acclimation Society of North America reputedly trying to introduce to North America every bird species mentioned in the works of William Shakespeare.[36] <---- wiki
