The House Sparrows inhabit a greater extent of country than almost any other bird, being found over the whole of the northern portion of the Eastern hemisphere; moreover, it is a remarkable fact that wherever met with they are always in a state of semi-domestication: even in Australia, into which country Sparrows were only introduced some few years ago, they hold the same relation to man as in Europe. Few villages are to be found in which these little creatures have not settled, and that in the fullest sense of the word, as they never fly more than a mile from the place where they were born, except when in search of a spot on which to establish themselves. We are told by a Norwegian naturalist that these birds are yearly seen flying about some parts of Norway in couples, going from house to house, but that, not finding the country to their liking, they soon disappear, leaving no trace behind. Our House Sparrow is social in its habits, and even during the breeding season can hardly be said to live apart from its fellows; the nests are placed very close together, the males appearing to enjoy each other's society even whilst the process of incubation is going on. The young join the rest of the troop as soon as they can fly. During the whole time that corn can be obtained, or any green plants remain, these flocks fly daily over the neighbouring fields and plains in search of food, returning in the middle of the day to the villages, where they rest, and in the evening assemble upon the trees or roofs to make their preparations for passing the night--a proceeding that is always accompanied by great confusion and much squabbling. In the winter time these intelligent little creatures prepare beds or nests of the warmest description, into which they creep for shelter from the cold; they also frequent chimneys, quite regardless of the smoke and soot with which they are often covered.
