<P> The house sparrow originated in the Middle East and spread , along with agriculture , to most of Eurasia and parts of North Africa . Since the mid-19th century , it has reached most of the world , chiefly due to deliberate introductions , but also through natural and shipborne dispersal . Its introduced range encompasses most of North America , Central America , southern South America , southern Africa , part of West Africa , Australia , New Zealand , and islands throughout the world . It has greatly extended its range in northern Eurasia since the 1850s , and continues to do so , as was shown by the colonisations around 1990 of Iceland and Rishiri Island , Japan . The extent of its range makes it the most widely distributed wild bird on the planet . </P>
