One of the most widespread and abundant songbirds in the world today is the House Sparrow. It has a simple success formula; it associates with humans. Native to Eurasia and northern Africa, it has thrived in urban and farming areas all over the world including North America where it was introduced in New York in 1851. It is a permanent resident over most of its range, including North America.
Tough, adaptable, and aggressive, it survives on city sidewalks where few birds can make a living. It may even evict native birds from their nests.
