when were house sparrows introduced to north america
House sparrow The house sparrow originated in the Middle East and spread, along with agriculture, to most of Eurasia and parts of North Africa.[68] Since the mid-19th century, it has reached most of the world, chiefly due to deliberate introductions, but also through natural and shipborne dispersal.[69] 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.[70] It has greatly extended its range in northern Eurasia since the 1850s,[71] and continues to do so, as was shown by the colonisations around 1990 of Iceland and Rishiri Island, Japan.[72] The extent of its range makes it the most widely distributed wild bird on the planet.[70]
