Pipilo fuscus, var. albigula, BairdCAPE TOWHEE

Pipilo albigula, Baird, P. A. N. S. Nov. 1859, 305 (Cape St. Lucas).—Elliot, Illust. Am. Birds, I, pl. xv (“= P. mesoleucus”).—Cooper, Orn. Cal. I, 248.

Sp. Char. Similar to var. mesoleucus, having, like it, a distinctly rufous crown and white abdomen. Differing, however, in the following respects: The pale ochraceous gular area is more sharply defined, the buff being confined within the encircling series of dusky spots; the buff is palest posteriorly, instead of directly the opposite. The rufous of the crissal region is more restricted, only tingeing the anal region instead of invading the lower part of the abdomen, the white beneath also is shifted farther back, covering the abdomen alone, instead of the breast, the whole jugulum being distinctly ashy, like the sides. Wing, 3.80; tail, 4.25.

Hab. Cape St. Lucas.

A very large series of specimens from Cape St. Lucas agree in possession of the characters pointed out above, distinguishing them from mesoleucus, to which race the present one is most nearly related.

Habits. The White-throated or Cape Towhee of Cape St. Lucas was first met with by Mr. Xantus in the southern extremity of the peninsula of Lower California, and described by Professor Baird in 1859. Its close resemblance to P. mesoleucus suggests an equal similarity as to its habits, in regard to which we possess no actual knowledge. Mr. Xantus has furnished us with no memoranda as to the manners of the bird. We have only the brief mention among his notes to the effect that No. 4,855 is the nest with four eggs of this Pipilo, found in a wild Humulus thicket; and that No. 5,076 is a nest with eggs of the same, found in a thicket of wild roses in the garden fence.

Judging from the large number of the nests and eggs of this species collected by that gentleman at Cape St. Lucas, it would seem to be very abundant in that locality.

The eggs of this variety measure .95 of an inch in length and .72 in breadth. They bear a strong resemblance to those of the P. fuscus, but the markings are darker and more distinctly defined, standing out with a clear and striking effect, in marked contrast with the light background. The ground-color of the egg is a light tint of robin-blue. The markings of dots, dashes, and lines are all about the larger end, and are of a deep dark shade of purplish-brown, so dark as, except in a strong light, to be undistinguishable from black.

SECTION IIIBrown; throat without light patch Pipilo aberti, BairdABERT’S TOWHEE

Pipilo aberti, Baird, Stansbury’s Rep. Great Salt Lake, Zoölogy, June, 1852, 325 (New Mexico).—Ib. Birds N. Am. 1858, 516, pl. xxx.—Kennerly, P. R. R. X, b, pl. xxx.—Heermann, X, c, 15.—Cooper, Orn. Cal. 1, 244. Kieneria aberti, Bonap. Comptes Rendus, XL, 1855, 356.

6748 ♂

Sp. Char. General color of upper parts pale brownish yellowish-red; beneath brighter, and more ochraceous, especially on the under coverts, palest on the middle of the belly. Sides of head anterior to eyes, and chin dark brown. Bill and legs yellowish. Length, 9 inches; wing, 3.70; tail, 4.85.

Hab. Base of Rocky Mountains in New Mexico. Valley of Gila and Colorado.

This plainly colored bird is perhaps the largest of the North American Finches, and is without any blotches, spots, or variations of importance from one color, except on the chin and sides of the head. The bill is similar to that of P. erythrophthalmus, but the cutting edge is less concave and more sinuated. The tail is more graduated; the claws thicker and stronger. The wings are short and much rounded; the first quill shorter than the secondaries; fifth and fourth longest.

It may be easily distinguished from all the varieties of fuscus by the blackish lores and chin, as well as by the absence of any colored gular area, there being, instead, a pinkish rufous tinge prevalent over the whole throat and jugulum. There are no dusky spots across the throat as in fuscus.

Habits. Dr. Cooper assigns the base of the Rocky Mountains, in New Mexico, and the valleys of the Gila and Colorado Rivers, as the habitat of this species. Dr. Coues speaks of it as one of the most abundant and characteristic birds of those two valleys, and adds that it ranges northward to within a few miles of Fort Whipple, but is not found in the adjacent mountains. It was common at Fort Mohave, and particularly so at Fort Yuma.

Dr. Kennerly met with it at Camp No. 114, New Mexico, February 6, and again at Bill Williams Fork, February 12. He states that while travelling down the Big Sandy Creek and Bill Williams Fork, in the month of February, he found them very abundant. They confined themselves to the thick bushes near the water. Generally two or three were seen together. Their motions were very rapid, and their note was a peculiar, loud, chattering sound, sharp but not disagreeable. After leaving the Great Colorado he did not see it again.

On the borders of the Gila, east of Fort Yuma, Dr. Heermann found this bird in great abundance. It kept in the close sheltered thickets, where, secure from intrusion, it sought among the dead leaves for various seeds and insects and their larvæ, on which it feeds. In its habits it very much resembles the Pipilo fuscus, or Cañon Finch, diving into the bushes when alarmed, and repeating, at intervals, a short chirp. After leaving the Gila River he did not meet with any more, as he followed no longer the course of any large stream, for the borders of which these birds seem to have a decided preference.

Dr. Cooper regards this species as the almost exact counterpart of the Pipilo fuscus. The only difference he noticed in habits was in the character of its loud note of alarm, remarkably similar, however, to that of two very distinct birds of the same valley, namely, Centurus uropygialis and Phainopepla nitens. Like the Cañon Finch, this species is said to live almost constantly on the ground, but appears rather more gregarious, especially in winter.

About the first of April Dr. Cooper met with many of their nests. They were generally built in thorny shrubs, and were composed of a flooring of coarse twigs, or of green herbs, and strongly interwoven with strips of bark, grass, and leaves. One bird had taken advantage of the recent introduction of horses into the valley to obtain a lining of horse-hair for its nest. The eggs were in all cases only three, bluish-white, with brown spots and streaks in a ring near the large end, quite variable in number, and measuring one inch by .70. One of the nests was in a low mesquite-tree, another in a dense cluster of dead twigs hanging from a cottonwood. The time required for hatching was twelve or thirteen days, and in a fortnight more the young left the nest. Dr. Cooper found nests with eggs as late as May 25, and had no doubt that they raise two or more broods in a season. He adds that the song of the male, throughout April and May, is precisely like that of P. fuscus, and also reminded him of the notes of P. oregonus and of the eastern Black-throated Bunting (Euspiza americana).

Dr. Coues has kindly supplied me with the following interesting sketch of this species, as observed by him in Arizona:—

“This species appears to have a remarkably restricted geographical distribution. I never saw it at Fort Whipple, but on the Colorado bottom in the same latitude, and thence along the river to Fort Yuma, I found it to be one of the most abundant and characteristic birds of all. At the time I observed it, in September, it was generally in small flocks, and proved rather difficult to capture, partly because the dense underbrush it inhabited was almost impenetrable, and partly on account of its natural timidity. Everything along the river-bottom is scorched with the heat, and the dry dead twigs constantly snap at a touch, with such noise that it is almost impossible to force a passage through the underbrush without alarming all its inmates. The bird occurs everywhere along the river-side, but is particularly numerous on the patches of mesquite, and the extensive areas grown up to young willows and cottonwoods, and the arrowwood (Tessaria borealis). Its ordinary cry of alarm, if not its call-note, is a loud, clear chirp, very different from the mewing sound made under similar circumstances by its congener, the P. megalonyx. The latter, as is well known, is almost exactly like that of a Catbird. I never heard the song of this bird, which appears to sing only during the breeding-season, but Dr. Cooper says it resembles that of the western Black Pipilos, and I can indorse his observation, that this is curiously like the monotonous notes of the Black-throated Bunting,—Chip, chip, chee-chee-chee; the first two syllables deliberately pronounced, the others more rapidly enunciated, with greater emphasis. The associates of this species seem to be few, if indeed they be not confined to the P. mesoleucus, a very near ally. The moult seems to me unusually protracted, as many September specimens were still in poor plumage.

“Excepting my experience with this bird on the Colorado, I only met with it on the Hassayampa, a small stream a few miles from Fort Whipple, yet in a somewhat different region, across a slight mountain-ridge, lower and warmer. Two specimens were secured, adult and young, the first week in August.”

Dr. Coues, on his way from Arizona to the Pacific (Ibis, 1866, p. 261), mentions that he was often startled by the loud, clear, sharp chirp of this bird, which, though fringilline in character, is more than usually powerful, and is its alarm-note. Everywhere in the Colorado Valley this was one of the most characteristic birds. Fort Yuma seemed to be its head-quarters. It is, like all its congeners, a retiring species, and keeps perseveringly in the almost impenetrable undergrowth. It is said to be more decidedly gregarious than most of the genus, often collecting in flocks of a dozen or more, wandering restlessly, yet in a cautious manner, through the thickets.

A nest with eggs, procured at Fort Mohave by Dr. Cooper, is in the Smithsonian Collection (No. 7,276). The egg measures .93 by .70 of an inch, is obovate in shape, being much rounded at the smaller end. Its ground-color is a dull white, without any perceptible tinge of blue,—though possibly bluish when fresh,—with heavy dots and occasional delicate, hair-like, zigzag markings of black. These markings are wholly confined to the larger end. One of the eggs has these markings much finer, consisting of minute dots, more dense, and upon the apex of the larger end. The nest is loosely built and very bulky. Its external diameter is about six inches, and its depth three. The cavity is three inches wide and two deep. It is constructed almost entirely of strips of inner bark, the coarser, ribbon-like pieces being used on the outer portion, and the finer shreds composing the lining. Externally are also a few sticks about one quarter of an inch in diameter.

Sp. Char. Above dull grayish olive-green. Crown uniform chestnut. Forehead with superciliary stripe, and sides of the head and neck, the upper part of the breast and sides of the body, bluish-ash. Chin and upper part of throat abruptly defined white, the former margined by dusky, above which is a short white maxillary stripe. Under tail-coverts and sides of body behind brownish-yellow. Tail-feathers generally, and exterior of wings, bright olive-green, the edge and under surface of the wings bright greenish-yellow; edge of first primary white. First quill longer than eighth, fourth longest. Length, about 7 inches; wing, 3.20; tail, 3.65.

Hab. Whole of the Middle Province, including the Rocky Mountains and eastern slope of the Sierra Nevada; north to beyond the 40th parallel; south to Mexico.

In this species the wing is considerably rounded, the tertials considerably shorter than the primaries, and not exceeding the secondaries; the fourth quill longest, the first shorter than the sixth, the second and fifth quills considerably longer than the rest. The tail is long and considerably graduated, the outer feather half an inch shortest; the feathers broad and obtusely pointed, the corners rounded.

Pipilo chlorurus.

The extent of the chestnut of the crown varies somewhat; more extended probably in the males. The region on the side of the head, adjoining the nostrils, is whitish; the small feathers under the eye are spotted with the same. The posterior outline of the ash of the breast is much less sharply defined than the anterior.

Specimens vary in the brightness of the olive above, which is never as pure as that of the wings and tail. The olive of the tail, too, is darker than that of the wings.

Pipilo chlorurus.

A very young bird (1,896) has the whole under parts dull white, streaked and spotted on the sides of the throat and on the breast with dark brown. The crown and back are also thickly spotted. In 5,734 the ash of the breast has made its appearance; the middle of the belly is white, spotted; the chin white, encircled by spots. The spots above are restricted to near the head, and there is a small central patch of chestnut on the crown.

No. 1,896 is the original “Green-tailed Sparrow” killed July 12, 1834, by Townsend, and described in an extract of a letter to Mr. Audubon, published page 336 of Vol. V. of the Ornithological Biography.

Habits. Dr. Kennerly, who procured a specimen of this bird at San Elizario, Tex., December 16, states that it was obtained with some difficulty. For several successive days it was found in the same place, occupying a small clump of very thick weeds. When aroused, which was only accomplished with some effort, its flight was short, rapid, and decidedly irregular. Its motions on the ground were very awkward. This species was found by Mr. Ridgway very generally distributed throughout the fertile mountain portions of the interior. It was not seen by him in California, and was first met with in the ravines at the base of the eastern slope of the Sierra Nevada. On the high mountain-ranges it was a characteristic and the best-known singer, as well as one of the most abundant of the Fringillidæ, being found in all bushy places, from the bases to the summits of the mountains. It is exclusively a summer species, arriving at Carson City about the middle of April. He describes the usual note of this bird as very peculiar, and, as nearly as can be described, a sweet laughing utterance of the syllables keek-keek´, a little resembling the tweet of a Canary, but very musical. This curious note was generally uttered when anything unusual attracted its attention, such as the approach of an intruder. Then, with elevated tail and its very conspicuous red cap raised, it would hop familiarly and unsuspiciously about. He adds that it is a songster of high merit, in power and variety ranking very little below the song of the Chondestes grammaca. The song varies in the modulations greatly with the individual, but the same general style is preserved. At times it seemed to have a slight resemblance to the song of Bewick’s Wren, and at others to that of a Cyanospiza, and more rarely, to be the reproduction of a passage from the song of the Chondestes.

In the early part of July, near Austin, in the cañons of the mountains, he found these birds breeding in the greatest abundance, and later in the same month a few of its nests were found on the East Humboldt Mountains. All of its nests, with hardly an exception, were placed from eighteen inches to two feet above the ground, among the thick bushes of a species of Symphoricarpus, or “snow-berry,” which grows in great abundance upon the sides of the cañons of those mountains. The maximum number of eggs was four. It was also quite a common bird in the Wahsatch Mountains, though less abundant than the P. megalonyx.

Mr. Allen found this Finch quite numerous in Colorado Territory, and speaks of its song as very peculiar and very pleasing. It is said to resemble in no respect the eastern Towhee Finch, with which it is classed, but much more closely the group of Sparrows, so familiarly represented at the east by the White-throated, being like them in habits, song, and general aspect. It was more common among the foot-hills than on the plains. In Utah, according to Mr. Allen, this Finch begins to appear in numbers about September 20, from its breeding-haunts in the mountains.

Dr. Coues met with this species in Arizona, but only as a spring and autumn migrant. None remained there in summer to breed, and none were found there in the winter. In its migrations it passed rapidly by Fort Whipple, being found there only during the latter part of April and the beginning of May, and during the month of September. At those seasons it appeared to him the most silent and retiring of all the Pipilos. He found it very difficult to either observe its habits or to capture it. It winters sparingly at Fort Mohave.

Specimens of this bird were taken near Lookout Mountain by C. S. McCarthy, and at Gilmer, in Wyoming Territory, by Mr. Durkee.

Dr. Heermann, in his Report on the birds observed on the 32d. parallel, under Lieutenant Parke, mentions first meeting with this species near Tucson. They were frequenting, in numbers, the thick undergrowth, and were seeking seeds and insects on the ground. They seemed inclined to shun observation, and always kept in the most retired situations. They were sociable among themselves, going about singly or in pairs, associated with the Poospiza bilineata and two or three other kinds of Finch. When started they fly low, diving into the bushes, and soon disappear from sight. Occasionally, until reaching El Paso, Texas, birds of this species were met with, mingling with the flocks of migrating Fringillidæ. He there procured a pair apparently just entering upon incubation.

Instead of being suited by color, like most of the other Pipilos, to inhabit dark thickets and among dry leaves, this species is clad in a gayer livery, and seems well adapted for concealment in its summer resorts, and also among the growing vegetation of the lower country during the rainy season. Dr. Heermann found a few wintering in the Colorado Valley, and yet more at San Diego, but they left both places in March. He found them silent and shy, hiding very closely in the bushes, and feeding altogether on the ground. The only note he heard, resembled the crowing note of the California Quail.

Among the memoranda of Mr. Xantus, made near Fort Tejon, are the two following: “4,839, nest and two eggs (of Pipilo chlorurus) found in a dry hedge in Mr. Ritchie’s garden; 5,083, nest and eggs found in a dark garden-hedge.”

The eggs of the chlorurus are like those of no other Pipilo that I have met with. They are peculiar in shape, being nearly of an exact oval, neither end being apparently much more rounded than the other. Their ground-color is white with a bluish tint, over which is profusely diffused a cloud of fine dottings of a pinkish-drab. These markings are occasionally so fine and so thickly distributed as to give to the egg the appearance of a uniform color, or as an unspotted pinkish drab-colored egg. Occasionally the dots are deeper and larger, and more sparsely diffused.

In considering the eggs of the Pipilos in general we find certain variations which deserve more than a passing notice. Those of erythrophthalmus, oregonus, arcticus, and megalonyx are all fringilline in their characters, and have a marked affinity to eggs of Melospiza, Zonotrichia, and many other genera of this order. The eggs of aberti, fuscus, mesoleucus, and albigula are also all closely alike, and exhibit a very close resemblance to those of the Agelaii, and even of the Icteri, while the eggs of P. chlorurus, though of a fringilline character, are unlike either style.

Family ALAUDIDÆ.—The Larks

Char. First primary very short or wanting. Tarsi scutellate anteriorly and posteriorly, with the plates nearly of corresponding position and number. Hind claw very long and nearly straight. Bill short, conical, frontal feathers extending along side of the bill; the nostrils concealed by a tuft of bristly feathers directed forward. Tertials greatly elongate beyond the secondaries.

Subfamilies and Genera

Alaudinæ. Bill stout, short, and conical; nasal fossæ transverse and completely filled by the thick tuft of bristly feathers, and perforated anteriorly by a circular nasal opening. (Old and New World.)

Crown with a depressed soft crest of feathers, of normal structure; a spurious primary; tail deeply emarginate … Alauda.

Crown without a crest, but occiput with an erectile tuft of narrow elongated feathers on each side. No spurious primary; tail square, or slightly rounded … Eremophila.

Calandritinæ. Bill broader, more depressed, and straighter at the base; nasal fossæ longitudinal, large, elongated, the nasal opening rather linear. (Old World.)

Of the Alaudidæ only the two genera diagnosed above belong to the American continent; and one of them is properly only a wanderer from the Old World, while the other is cosmopolitan.

The most characteristic feature of the Larks among other oscine families is seen in the scutellation of the tarsus. The anterior half of this is covered by divided scales lapping round on the sides, but instead of the two plates which go one on each side of the posterior half and unite ultimately behind as an acute ridge, there is but one which laps round on the sides, and is divided into scales like the anterior ones, but alternating with them. The posterior edge of the tarsus is as obtuse as the anterior, instead of being very acute. There is a deep separating groove on the inner side of the tarsus; and there may be really but one plate divided transversely, the edges meeting at this place.

In the elongated hind claw and lengthened tertials, general style of coloration, mode of life, and manner of nesting, there is a decided approximation in the Alaudidæ to the Anthinæ, of the family Motacillidæ; but in these the posterior edge of the tarsus is sharp and undivided transversely, the toes more deeply cleft, the bill more slender, etc.,—their relations being rather nearer to the Sylvicolidæ than to the present family.

Genus ALAUDA, Linn Alauda, Linn. S. N. 1735

Gen. Char. Bill very small, less than half the length of the head, conical; nostrils exposed; rictal bristles quite strong; commissure without notch; tarsus much longer than middle toe; lateral toes equal; posterior toe about as long as the middle, its claw longer than the digit, and nearly straight; claws of anterior toe very small. Wing long, pointed, the third and fourth (apparently second and third) quills longest, the second and fifth successively, a little shorter; the first so small as to be almost concealed; tertials much elongated, reaching about half-way from end of secondaries to tip of primaries; their ends emarginated; tail rather deeply emarginated, and a little more than half the length of the wing.
