Which of the following birds is considered non-native to the United States?

• A. House sparrow
• B. Blue jay
• C. Woodpecker
• D. American goldfinch

Answer: (A)

The house sparrow is considered non-native to the United States because it was originally introduced from Europe in the mid-19th century. This bird has adapted well to urban environments and has since become widespread across North America. In contrast, the blue jay, woodpecker, and American goldfinch are all native species that have evolved alongside the North American ecosystems and play important roles in those environments. Understanding the distinctions between native and non-native species is essential for wildlife management, as non-native species can sometimes disrupt local ecosystems and outcompete native wildlife.
