Eugene Schieffelin was an American amateur ornithologist who belonged to the New York Genealogical and Biographical Society and the New York Zoological Society. In 1877, he became chairman of the American Acclimatization Society and joined their efforts to introduce non-native species to North America for economic and cultural reasons.
In 1890, Schieffelin released 60 imported starlings from England into New York City’s Central Park. He did the same with another 40 birds in 1891. According to an oft-repeated story, Schieffelin supposedly introduced starlings as part of a project to bring to the United States all the birds mentioned in the works of William Shakespeare. Some historians have cast doubt on this story, as no record of it exists until the 1940s. He may have also been trying to control the same pests that had been annoying him thirty years earlier, when he sponsored the introduction of the house sparrow to North America.
Schieffelin’s efforts were part of multiple releases of starlings in the United States, ranging from the mid-1870s through the mid-1890s. The successful spread of starlings has come at the expense of many native birds that compete with the starling for nest holes in trees.[18] The starlings have also had negative impact on the US economy and ecosystem. European starlings are now considered an invasive species in the United States.
