In 1890, European starlings introduced in New York’s Central Park began a spread that eventually produced about 150 million birds across North America

A small experiment in New York's Central Park initiated a major biological invasion. European starlings rapidly spread across North America after their 1890 introduction. These adaptable birds now number around 150 million across the continent. Their presence causes significant agricultural losses and displaces native species. This event serves as a key example of non-native species impacts.
