      Sp. Char. General tint of upper parts rufous and distinctly streaked with rufous-brown, dark-brown, and ashy-gray. The crown is rufous, with a superciliary and median stripe of dull gray, the former lighter; nearly white anteriorly, where it sometimes has a faint shade of yellow, principally in autumn; each feather of the crown with a narrow streak of black forming about six narrow lines. Interscapulars black in the centre, then rufous, then pale grayish on the margin, these three colors on each feather very sharply contrasted. Rump grayer than upper tail-coverts, both with obsolete dark streaks. There is a whitish maxillary stripe, bordered above and below by one of dark rufous-brown, and with another from behind the eye. The under parts are white; the jugulum and sides of body streaked with clear dark-brown, sometimes with a rufous suffusion. On the middle of the breast these marks are rather aggregated so as to form a spot. No distinct white on tail or wings. Length of male, 6.50; wing, 2.58; tail, 3.00. Bill pale brown above; yellowish at base beneath. Legs yellowish.

      Hab. Eastern United States to the high Central Plains.

      Specimens vary somewhat in having the streaks across the breast more or less sparse, the spot more or less distinct. In autumn the colors are more blended, the light maxillary stripe tinged with yellowish, the edges of the dusky streaks strongly suffused with brownish-rufous.

      The young bird has the upper parts paler, the streaks more distinct; the lines on the head scarcely appreciable. The under parts are yellowish; the streaks narrower and more sharply defined dark brown.

      As already stated, this species varies more or less from the above description in different parts of North America, its typical races having received specific names, which it is necessary to retain for them as varieties.

      Habits. The common Song Sparrow of eastern North America has an extended range of distribution, and is resident throughout the year in a large part of the area in which it breeds. It nests from about South Carolina north to the British Provinces of Nova Scotia and New Brunswick at the east, and to a not well-defined limit in British America. The most northern points to which it has been traced are the plains of the Saskatchewan and the southern shore of Lake Winnepeg, in which latter place Mr. Kennicott found it breeding. It is said by Dr. Coues to breed in South Carolina, and by Mr. Audubon in Louisiana, but I have never seen any of their eggs from any point south of Washington. In winter it is found from Massachusetts, where only a few are observed, to Florida. It is most abundant at this period in North and South Carolina. It is not mentioned in Dr. Gerhardt’s list as being found in Northern Georgia at any season of the year. Mr. Ridgway informs me that it does not breed in Southern Illinois. Its song is not popularly known there, though he has occasionally heard it just before these Sparrows were leaving for the north. This species winters there in company with the Z. albicollis and Z. leucophrys, associating with the former, and inhabiting brush-heaps in the clearings.

      To Massachusetts, where specimens have been taken in every month of the year, and where they have been heard to sing in January, they return in large numbers usually early in March, sometimes even in February. It is probable that these are but migrants, passing farther north, and that our summer visitants do not appear among us until the middle of April, or just as they are about to breed. They reach Maine from the 15th to the 25th, and breed there the middle of May. In Massachusetts they do not have eggs until the first week in May, except in very remarkable seasons, usually not until after the Bluebird has already hatched out her first brood, and a week later than the Robin.

      The tide of returning emigration begins to set southward early in October. Collecting in small loose flocks, probably all of each group members of the same family, they slowly move towards the south. As one set passes on, another succeeds, until the latter part of November, when we no longer meet with flocks, but solitary individuals or groups of two or three. These are usually a larger and stouter race, and almost suggest a different species. They are often in song even into December. They apparently do not go far, and are the first to return. In early March they are in full song, and their notes seem louder, clearer, and more vibratory than those that come to us and remain to breed.

      The Song Sparrow, as its name implies, is one of our most noted and conspicuous singers. It is at once our earliest and our latest, as also our most constant musician. Its song is somewhat brief, but is repeated at short intervals, almost throughout the days of spring and early summer. It somewhat resembles the opening notes of the Canary, and though less resonant and powerful, much surpasses them in sweetness and expression. Plain and homely as this bird is in its outward garb, its sweet song and its gentle confiding manners render it a welcome visitor to every garden, and around every rural home wherein such attractions can be appreciated. Whenever these birds are kindly treated they readily make friends, and are attracted to our doorsteps for the welcome crumbs that are thrown to them; and they will return, year after

Winter plumage. Gray above more olivaceous, the black streaks more subdued by a rufous suffusion; streaks beneath with the rufous predominating, sometimes without any black.

Winter plumage. Above rusty-olive, with little or no ashy, the black streaks broad and distinct. Streaks beneath with the black and rusty in about equal amount.

In summer the streaks beneath are entirely intense black; in winter they have a slight rufous external suffusion.

Melospiza melodia, var. mexicana, Ridgway. Mexican Song Sparrow. ? ? Melospiza pectoralis, von Müller.

Sp. Char. (Type, 60,046, Puebla, Mexico, A. Boucard.) Similar to M. melodia, but ground-color above olive-brown; inner webs of interscapulars pale ashy, but not in strong contrast. Crown and wings rusty-brown, the former with broad black streaks, and divided by a just appreciable paler line; back with broad black streaks without any rufous suffusion. Superciliary stripe pure light ash, becoming white anterior to the eye; two broad, dark-brown stripes on side of head,—one from the eye back along upper edge of auriculars, the other back from the rictus, along their lower border. Lower parts pure white, the flanks and crissum distinctly ochraceous; markings beneath broad and heavy, entirely pure deep black; those on the jugulum deltoid, on the sides linear. Wing, 2.60; tail, 2.85; bill, .37 and .24; tarsus, .85; middle toe without claw, .68. This may possibly be the M. pectoralis of von Müller. The description cited above, however, does not agree with the specimen under consideration. The pectoral spots are expressly stated to be brown, not even a black shaft-streak being mentioned, whereas the pure black spots of the specimen before us render it peculiar in this respect, being, in fact, its chief characteristic.
