When first introduced into the United States in 1851, house sparrows were protected from predators and fed. However, populations expanded enormously in North America and they were soon considered a nuisance species. Since the 1960's, with the changes in farming to larger, single crop farms, populations have declined. They are not, however, seen as threatened and are not included in most Canadian and U.S. regulations.
