The House Sparrow (Passer domesticus) is a member of the Old World sparrow family Passeridae, considered by some to be a relative of the Weaver Finch Family. It occurs naturally in most of Europe and much of Asia. It has also followed humans all over the world and has been intentionally or accidentally introduced to most of the Americas, sub-Saharan Africa, New Zealand and Australia as well as urban areas in other parts of the world. It is now the most widely distributed wild bird on the planet. In the United States it is also colloquially known as the English Sparrow to distinguish it from native species.
