Teach the Starlings
Eugene Scheiffelin being the incredibly short sighted fellow who decided to introduce the birds of Shakespeare to the United States in the late 19th century. One of which is the European starling.
Though many of Scheiffelinâ€™s introduced birds never really took off, those beloved little starlings virtually spread like wildfire across North America, displacing staggering numbers of native birds from their niches. With a North American population of more than 200 million, it is now the most common bird on the continent. Nice going, Scheiffelin.
