The Sparrow will attach itself to man, but never sufficiently so to overlook the precautions necessary for its safety; it is ever upon its guard, and when angry even its inflated plumage cannot conceal the glances of its bright and crafty little eye; the unexpected opening of a window, the approach of a stranger, or even a stick held up like a gun, will at once excite alarm and cause its instant flight. Unlike the Pigeon race, this bird seems to become more wary and cunning as its intimacy with man increases--indeed, it never seems to forget the lessons taught by experience. Despite the clumsiness of its shape, the Sparrow has an air indicative of considerable spirit, as it hops energetically over the ground with tail borne aloft and head erect. The social disposition of these birds in no way interferes with their natural inclination to pick a quarrel upon every opportunity, and the most ludicrous combats often take place between the males relative to the appropriation of a mate. On these occasions, when the battle rages furiously, males and females alike mingle in the strife, until both parties come pecking, tumbling, and screaming through the air, to conclude the fight upon some neighbouring roof, forgetful in their fury of the safety they usually prize so highly, and take such precautions to ensure. During these contests they carry the head and neck erect, the tail raised, and their wings somewhat drooping. The Sparrow seldom flies at any great height; if perched upon a steeple, or other similar elevation, it will drop rapidly towards the ground before commencing its flight, rising again in a direct line when it wishes to attain the same altitude as before, although this attempt at soaring appears to cost the bird a great effort; it prefers, however, living at some distance from the ground.
