around. Within is a compactly woven inner nest, composed of straws, mingled and interwoven with horse-hairs. The cavity has a depth and diameter of two inches. The eggs, four in number, measure .85 by .63 of an inch. Their form is a rounded oval, distinctly pointed at one end. They have a greenish-white ground, marked and blotched with splashes of purplish and reddish brown.
Melospiza heermanni, Baird, Birds N. Am., 1858, 478, pl. 70, f. 1.—Cooper, Orn. Cal. 1, 212.
Sp. Char. Somewhat like melodia, but darker. The streaks on the back and under parts blacker, broader, more distinct, and scarcely margined with reddish, except in winter plumage. The median stripe on vertex indistinct. General shade of coloration olivaceous-gray rather than rusty. Length, 6.40; wing, 2.56; tail, 3. Bill and legs in size and color most like melodia.
Hab. Southern California; eastern slope of Sierra Nevada (Carson City), and West Humboldt Mountains, Nev.; Ridgway.
Of the various races of M. melodia, this one approaches nearest the typical style of the Atlantic region; agreeing with it in thicker bill and shorter tail, as compared with the var. fallax, which occurs between them. It differs from the var. melodia, however, in a more grayish cast to the ground-color of the upper plumage, being olivaceous-gray, rather than reddish; the black dorsal streaks are very much broader than the rusty ones, instead of about equal to them in width, and the edges to the interscapular feathers are not appreciably paler than the prevailing shade, instead of being hoary whitish, in strong contrast. In spring the “bridle” on the side of the throat and the spots on the jugulum have the black of their central portion in excess of their external rufous suffusion; but in autumn the rusty rather predominates; at this season, too, the rusty tints above overspread the whole surface, but the black streaks are left sharply defined. At all seasons, the spots on the jugulum are broader and rather more numerous than in melodia. The young can scarcely be distinguished from those of melodia, but they have the dark streaks on the crown and upper tail-coverts considerably broader.
Habits. The California Song Sparrow has been named in honor of the late Dr. Heermann, who first obtained specimens of this bird in the Tejon Valley, and mistook them for the Zonotrichia guttata of Gambel (M. rufina), from which they were appreciably different. Whether a distinct species or only a local race, this bird takes the place and is the almost precise counterpart, in most essential respects, of the Song Sparrow of the East. The exact limits of its distribution, both in the migratory season and in that of reproduction, have hardly yet been ascertained. It has been found in California as far north as San Francisco, and to the south and southeast to San Diego and the Mohave River.
The California Song Sparrow is the characteristic Melospiza in all that portion of the State south of San Francisco. It is found, Dr. Cooper states, in every locality where there are thickets of low bushes and tall weeds, especially in the vicinity of water, and wherever unmolested it comes about the gardens and houses with all the familiarity of the common melodia. The ground, under the shade of plants or bushes, is their usual place of resort. There they diligently search for their food throughout the day, and rarely fly more than a few yards from the place, and remain about their chosen locality from one year’s end to another, being everywhere a resident species. In the spring they are said to perch occasionally on some low bush or tree, and sing a lively and pleasant melody for an hour at a time. Each song, Dr. Cooper remarks, is a complete little stanza of a dozen notes, and is frequently varied or changed entirely for another of similar style, but quite distinct. Although no two birds of this species sing just alike, there is never any difficulty in distinguishing their songs when once heard. There is, he thinks, a similarity of tone and style in the songs of all the species of true Melospiza, which has led other observers to consider them as of only one species, when taken in connection with their other similarities in colors and habits.
Dr. Cooper found a nest, presumed to belong to this bird, at Santa Cruz, in June. It was built in a dense blackberry-bush, about three feet from the ground, constructed with a thick periphery and base of dry grasses and thin strips of bark, and lined with finer grasses. The eggs were of a smoky white, densely speckled with a dull brown. Although this bird was abundant around Santa Cruz, he was only able, after much searching, to find two of their nests. One was in a willow, close against the tree, and three feet from the ground, containing, on the 11th of May, four eggs partially hatched. This was built of coarse dry stems and leaves, lined with finer grasses and horse-hair. It was five inches in external diameter, and four high. The cavity was two and a half inches deep and two in diameter. These eggs had a ground of greenish-white, and were blotched and spotted with a purplish-brown, chiefly at the larger end. They were .82 by .62 of an inch in measurement. The ground-color was paler and the spots were darker than in eggs of Z. gambeli, the whole coloring much darker than in those of M. fallax. This nest was apparently an old one used for a second brood.
Another nest found as late as July 10, and doubtless a second brood, was in a thicket, six feet from the ground, and also contained four eggs. Dr. Cooper states that he has seen the newly fledged young by the 7th of May.
Dr. Heermann, in his account of this bird, which he supposed to be the guttata of Dr. Gambel, states that he found it abundant throughout the whole country over which he passed, and more especially so in the bushes bordering the streams, ponds, and marshes. Its notes, sweet, and few in number, resembled those of the common Song Sparrow. Its nests, usually built in thick tufts of bushes, were composed externally of grasses and lined with hair, and contained each four eggs, with a pale bluish-ash ground, thickly covered with dashes of burnt umber. Eggs of this species, from near Monterey, collected by Dr. Canfield, vary in measurement from .85 by .65 of an inch to .88 by .70,—larger than any eggs of Melospiza melodia that I have seen. Their ground-color is a light green. The blotches are large, distinct, and more or less confluent, and of a blended reddish and purplish brown. They are in some diffused over the entire egg, in others disposed around the larger end.
Ammodromus samuelis, Baird, Pr. Boston Soc. N. H. VI, June, 1858, 381.—Ib. Birds N. Am. 1858, 455, pl. lxxi, f. 1.—Cooper, Orn. Cal. 1, 191. Melospiza gouldi, Baird, Birds N. Am. 1858, 479.
Sp. Char. Somewhat like Melospiza melodia, but considerably smaller and darker. Bill slender and acute, the depth not more than half the culmen. Above streaked on the head, back, and rump with dark brown, the borders of the feathers paler, but without any rufous. Beneath pure white; the breast, with sides of throat and body, spotted and streaked with black, apparently farther back than on other species. Wings above nearly uniform dark brownish-rufous. Under tail-coverts yellowish-brown, conspicuously blotched with blackish. An ashy superciliary stripe, becoming nearly white to the bill, and a whitish maxillary one below which is a broad blackish stripe along the sides of neck; the crown with faint grayish median line. Length, 5 inches; wing, 2.20; tail, 2.35. Bill dusky; legs rather pale. Bill, .35 from nostril by .24 deep; tarsus, .71; middle toe without claw, .58. (5,553 ♂, Petaluma, Cal.)
Hab. Coast region of California, near San Francisco.
The above description is of a specimen in worn summer plumage, when the markings have not the sharp definition seen in the autumnal plumage. The autumnal plumage is as follows: Ground-color above grayish-olive, outer surface of wings, with the crown, more rufous; crown with narrow, and dorsal region with broad, stripes of black, the latter with scarcely a perceptible rufous suffusion; crown with a distinct median stripe of ashy. Streaks on jugulum, etc., broader than in the type, and with a slight rufous suffusion. Wing, 2.20; tail, 2.35; bill from nostril .31, its depth .22; tarsus .74; middle toe without claw, .60.
The type of Melospiza gouldi resembles the last, and differs only in having a more distinct rufous suffusion to the black markings; the measurements are as follows: Wing, 2.20; tail, 2.35; bill, .33 by .23; tarsus, .73; middle toe without claw, .59.
This is probably a dwarfed race of the common species, the very small size being its chief distinctive character. The colors are most nearly like those of heermanni, but are considerably darker, caused by an expansion of the black and contraction
