European Starlings and House Sparrows Introduced in 19th Century Now Widespread in North America
In the 19th century, small groups of European birds were introduced to North America, leading to widespread populations today. In 1890, 80 European Starlings were released in New York's Central Park, eventually numbering around 93 million, while in 1851, 100 House Sparrows were introduced in Brooklyn and spread across the continent. Both species adapted well to diverse environments, often thriving near human settlements. Although their populations peaked in the 20th century, recent declines have been noted, with studies highlighting their ecological impact and adaptability.
