      Sp. Char. Above dark olive-brown, the crown with a very slight tinge of scarcely appreciable dark rufous. Under parts with the color somewhat similar, but of a lighter shade, and washed with grayish; middle of the belly only whitish; the under tail-coverts pale rufous, shading into lighter about the vent and sides of lower belly; chin and throat well-defined pale rufous, margined all round by brown spots, a few of them scattered within the margin. Eyelids and sides of head, anterior to the eye, rufous like the throat. One or two feathers on the lower part of the breast with a concealed brown blotch. Outer primary not edged with white. Fifth quill longest; first shorter than ninth, or even than secondaries. Bill pale brown, darker above; legs light. Length, 8.50 inches; wing, 4.00; tail, 4.60.

      Hab. Coast region of California.

      The bill is sinuated, as in P. aberti, differing from that of P. erythrophthalmus.

      This race is very similar to the original P. fuscus of Mexico, the original description of Swainson answering almost exactly. It is, however, considerably larger; the proportions of wing are similar; and there is no decided indication of whitish in the middle of the body beneath, such as is always distinctly appreciable in fuscus, and still more in mesoleucus.

      A young bird differs but little from the adult except in having obsolete dusky streaks below; the upper parts are uniform.

      Habits. The Brown, or Cañon Finch of California is found nearly throughout the State of California. Mr. Xantus obtained it at Fort Tejon, and Mr. Ridgway observed it among the chaparrals on the foothills of the western slope of the Sierras.

      Dr. Cooper considers the name of Cañon Finch ill applied to this species, as it is equally plentiful in level districts, wherever trees and shrubbery exist. He regards it as one of the most abundant and characteristic birds of California, residing in all the lower country west of the Sierras, and extending up the slopes of the Coast Range to the height of three thousand feet. They are said to have habits very similar to those of all the other species, living much upon the ground, and seeking their food among the dead leaves, which they greatly resemble in color. This resemblance Dr. Cooper regards as a great protection to them from Hawks; their hues also correspond with those of the earth and the dusky foliage during most of the year. They are thus less conspicuous in the light, and they venture more fearlessly forth and feed in open grounds.

      They have but little song, and only utter a few faint chirps and hurried notes, as they sit perched upon some low bush, in the spring. At San Diego Dr. Cooper saw the first nest with eggs on April 17, but some birds had laid much earlier, as he found young hatched by the 20th. He afterwards observed other nests, all of which were built in bushes, from two to four feet from the ground, and all but one contained three eggs; the other had four. He has found them built in low trees, and one in a vine growing over the porch of a house. The nest is formed of coarse twigs, bark, and grass, is thick and large, and is lined with fine root-fibres and finer grasses. The eggs are pale blue, spotted with purplish-brown blotches, mostly small and scattered. He gives the measurement of the eggs as .90 by .65 of an inch. In the more northern part of the State they are said to lay four eggs oftener than three. They are supposed by him to have two broods in a season.

      Colonel McCall has no doubt that they are found throughout California, as he has met with them from the upper waters of the Sacramento to the mouth of the Gila; the former having its origin in the extreme north, and the latter touching the extreme southern boundary of the State. It is most abundant south of Santa Barbara.

      Colonel McCall states that its habits and manners differ somewhat from those of the common Towhee and the Arctic Finches. Its flight is more even and regular, and is without that violent jerking of the tail from side to side, which gives such a singular appearance of awkwardness to the movements of the Towhee. It is less shy and suspicious than the Arctic. It is also much less decidedly a Ground Finch than either of the others. Its favorite abode he found to be the vicinity of watercourses, where it is generally to be seen in pairs, though he has, at times, surprised eight or ten together under the shade of a large bush at noon in a summer day, when he has had no difficulty in procuring three or four specimens before the party dispersed. It is at all times a familiar bird, boldly coming into the roads to feed, and permitting a close approach. If compelled to retreat, it darts suddenly into the thicket, but returns as soon as the cause of alarm has disappeared. Near Santa Barbara he found thirty or forty of these birds, in the month of July, dispersed over an old field of some five acres in extent, contiguous to a sea-beach, through which flowed a small stream of fresh water. They were feeding on the ground, sheltered by a rank growth of weeds. When one was flushed it flew into a neighboring tree instead of seeking shelter again in the weeds. The young at that time were fully fledged, and scarcely differed in the color of their plumage from the adults.

      Dr. Heermann once met with a nest of this bird built in a grapevine overhanging the Sacramento River. He describes the eggs of this species as differing entirely from any of this genus he had ever met with, and as having so great a resemblance to the eggs of the three different species of Blackbirds inhabiting California that they were liable to be confounded with them unless marked when taken from the nest.

      Dr. Newberry, who found this bird very common in the Sacramento Valley, states that when he first met with it, a strange bird to him, its habit of scratching among the dry leaves under the bushes, as well as its long tail and jerking flight from one clump of bushes to another, at once indicated to him its affinities.

      Among the memoranda made by Mr. Xantus at Fort Tejon are the following in reference to this species: “474, nest and two eggs, found May 19 on a small thorn-bush in a very dark thicket, about six feet from the ground; 1,675, nest and one egg, on a thick thorny bush, six feet from the ground; 1,851, nest and two eggs, May 12, on a rose-bush, four feet from the ground, eggs already incubated.”

      The eggs of this species measure one inch by .75, have a light ground of robin-blue, and are spotted and blotched with varying shades of dark and light purple. In some the color of the blotches is so deep as not to be distinguishable from black, except in a strong light. The lighter shades are a faint lavender.

      Sp. Char. Above very dull olivaceous-brown, with a grayish tinge; hood dull chestnut, conspicuously different from the back. Sides like the back, but paler; posteriorly, and about the vent and under tail-coverts, pale brownish-red. The ashy olive-brown of the sides scarcely meeting across the breast, the lower portion of which, with the upper belly, is rather pure white. The loral region, chin, throat, and upper part of the breast, pale yellowish-rufous, finely spotted on the sides and more coarsely across the breast with brown; an obscure spot in the middle of the breast; edge of outer primary white. Bill pale brown; legs flesh-color; first quill about equal to eighth, third and fourth longest. Length, 8.50 inches; wing, 3.80; tail, 4.70.

      Hab. Valley of Upper Rio Grande and across to the Gila River. East to Santa Caterina, New Leon.

      This race is similar in general appearance to P. crissalis, but the olive-brown СКАЧАТЬ
