House Sparrow - upper parts ashy-gray; middle of back and scapulars boldly streaked with black and bay. A dark chestnut; median tipped with white, forming a conspicuous wing-bar, bordering which is a black line. Greater coverts and inner quills with central black field bordered with bay. Tail dusky-gray, unmarked. Lower parts ashy, gray or whitish; chin and throat jet black, spreading on the breast and lores, bordered on side of neck with white. Bill blue-black; feet brown. Mountain Sparrow - Somewhat like the last, but smaller and otherwise different. Crown and nape a peculiar purplish-brown. Lores, chin, and throat-patch narrow and short, not spreading on breast, contrasted with ashy-white on side of head and neck; ear-coverts blackish. Back and scapulars streaked with black and bay, the streaking reaching to the purplish nape; rump and tail plain grayish-brown. Wings marked much as in P. domesticus, with a black and white bar across tips of median coverts, but also a narrow white bar across tips of greater coverts. Primaries more varied with ochrey-brown on outer webs, forming a basal spot and other edging. Below, ashy-gray, shaded on sides, flanks, and crissum with grayish-brown. Bill blue-black; feet brown." Elliot Coues, 1884

The Tree Sparrow, Passer montanus, breeds over most of Europe and Siberia, and allied forms occur in other parts of Asia. It has been introduced to Australia, and the United States (where it is known as the Eurasian Tree Sparrow or German Sparrow to differentiate it from the native, unrelated American Tree Sparrow), where German immigrants introduced it to the area around St. Louis in the 1870s. From there, it has slowly expanded its range into Illinois and Missouri. Changes in farming methods have meant that this species is declining in some parts of western Europe.
