Family CHAMÆADÆ.—The Ground-Tits

Char. Bill compressed, short, rather conical, not notched nor decurved. Culmen sharp-ridged. Nostrils linear, with an incumbent scale. Rictal bristles reaching beyond nostrils, which are scantily overhung by bristly feathers. Loral feathers bristly and directed forwards. Tarsi booted, or covered with a continuous plate anteriorly, with faint indications of scutellæ on the inner side. Basal joint of middle toe attached for about half its length on either side. Primaries ten; sixth quill longest. Plumage very lax.

Chamæa fasciata.

We have found it impossible to assign the genus Chamæa to any recognized family of American birds, and have accordingly been obliged to give it independent rank in this respect, although it may properly belong to some Old World group with which we are not acquainted. In its general appearance it approaches the Paridæ in loose plumage, bristly lores, want of notch to bill, etc.; but differs in the very much bristled rictus, sharp-ridged culmen, linear nostrils, booted tarsi, less amount of adhesion of the toes, etc. It approaches the Sylviidæ in the sharp-ridged culmen and bristly gape, but is otherwise very different. The excessively rounded wing is a peculiar feature, the sixth primary being the longest.

Chamæa fasciata.

The family may, perhaps, be best placed between the Sylviidæ and Paridæ.

This family has but one representative (Chamæa fasciata), and this confined to the coast region of California. The characters of the genus are those of the family.

Genus CHAMÆA, Gambel

Eggs light blue, unspotted; nest on low bushes.

Hab. Coast region of California.

Habits. This very interesting species, which seems to combine within itself the principal characteristics of the Wren and the Titmouse, was first described by the late Dr. Gambel of Philadelphia. So far as is now known, it is confined to the coast country of California, from Fort Tejon to the shore and from San Diego to the Sacramento. Dr. Gambel’s attention was first directed to it by the continued sound of a loud, crepitant, grating scold which he was constantly hearing in fields of dead mustard-stalks and other similar places. He at last discovered it to be this species, which from its peculiar habits he called a Wren-tit. It kept close to the ground, was difficult to be seen, and eluded pursuit by diving into the thickest bunches of weeds, uttering, when approached, its peculiar grating wren-like notes. When quietly watched it could be seen to search for insects, climbing twigs and dry stalks sideways, jerking its long tail, or holding it erect in the manner of a wren, which, in this position, it very much resembles. He describes it as at times uttering a slow, monotonous singing note like a chick-a-dee, represented by pee-pee-pee-peep. At other times its song is a varied succession of whistling. In spring it was heard, in pairs, calling and answering, in a less solemn strain, and in a manner not unlike a sparrow, with a brief pit-pit-pit, ending with a prolonged trill. If disturbed, they at once resumed their usual scolding cries.

Mr. Bell found this species chiefly frequenting damp places, and speaks of it as of pert habit, and not easily frightened. Its white iris, when observed in its native retreats, makes it easily recognized. This feature is as conspicuous in this bird as it is in the White-eyed Vireo. Its skin is remarkably strong, the muscles of the thighs powerful and well developed, and its whole muscular system exhibits an unusual strength and firmness.

Dr. Cooper’s observations in regard to this bird are a little different in some respects. He found it common everywhere west of the Sierra Nevada on dry plains and hillsides, among the shrubby undergrowth, but not in the forests. Instead of preferring damp places, he found it living where there is no water, except occasional fogs, for six or eight months at a time. Their movements can be observed by patient watching and keeping perfectly quiet, when they seem attracted by curiosity to such a degree as to approach one within a few feet, and fearlessly hop round him as if fascinated.

Dr. Cooper found their nests near San Diego built about three feet from the ground in low shrubs. They were composed of straw and twigs mixed with feathers and firmly interwoven. The cavity, about two inches wide and an inch and three fourths deep, is lined with grass and hair. The eggs, three or four in number, are of a pale greenish-blue, and measure .70 by .52 of an inch.

Family PARIDÆ.—The Titmice

Char. Bill generally short, conical, not notched nor decurved at tip. Culmen broad and rounded, not sharp-ridged at base. Nostrils rounded, basal, and concealed by dense bristles or bristly feathers. Loral feathers rough and bristly, directed forwards. Tarsi distinctly scutellate; basal joints of anterior toes abbreviated, that of middle toe united about equally for three fourths its length to the lateral: in Parinæ forming a kind of palm for grasping; outer lateral toe decidedly longer than the inner. Primaries ten, the first much shorter than the second. Tail-feathers with soft tips. Nest in holes of trees; eggs white, spotted with reddish.

With Cabanis we include the Nuthatches in the same family with the Titmice, and have prepared the above diagnosis to embrace both groups. They agree in having a conical bill, not notched nor decurved, with much rounded culmen, and nearly straight commissure, and rounded nostrils covered with dense bristles. These characters will readily distinguish them, in connection with the ten primaries, and tarsi with scutellæ on the anterior half only (as compared with Alaudidæ), from any other American Oscines.

The two subfamilies may be thus distinguished:—

Parinæ. Body compressed. Bill shorter than the head. Wings rounded, equal to or shorter than the rounded tail. Second quill as short as the tenth. Tarsus longer than the middle toe and claw, which are about equal to the hinder; soles of toes widened into a palm. Plumage rather soft and lax.

Sittinæ. Body depressed. Bill about equal to or longer than the head. Wings much pointed, much longer than the nearly even tail. Tarsus shorter than the middle toe and claw, which are about equal to the hinder. Plumage more compact.

Subfamily PARINÆ

The characters of the subfamily will be found sufficiently detailed above. The genera are as follows:—

Bill with curved outlines

Head with a long pointed crest. Wings and tail rounded.

Body full and large. Tail about equal to wings … Lophophanes.

Head with feathers full, but not crested. Wings and tail rounded.

Body full. Tail about equal to wings; rounded … Parus.

Body slender. Tail much longer than wings; much graduated … Psaltriparus.

Bill with outlines nearly straight

Head with compact feathers. Wings pointed.

Body slender. Tail rather shorter than the wings; nearly even … Auriparus.

823 ♂

Of this genus there are several North American species, all agreeing in general characters. One of these, the L. wollweberi, is given by Cabanis as typical, while he separates the L. bicolor generically under the name of Bæolophus, as having a rather different form of crest, stouter bill and feet, and longer wings. All of our species, however, vary in these characters, each one showing a different combination, so that we prefer to consider all as belonging to the same genus with P. cristatus.

The species, all of which have the under parts uniform whitish, may be arranged as follows:—

L. bicolor. Above plumbeous; forehead black; crown much like the back. Hab. Eastern Province United States.

L. atricristatus. Above plumbeous; forehead whitish; crown black. Hab. East Mexico, north to Rio Grande.

L. inornatus. Above olivaceous; forehead and crown like the back. Hab. South of Middle and Western Provinces of United States.

L. wollweberi. Sides of head banded black and white; crown ash; throat black. Hab. S. Rocky Mountains of United States; Mexico to Oaxaca.

Upper parts ash-color, with a tinge of olivaceous. Forehead dark sooty-brown. The feathers of the upper part of the head and crest obscurely streaked with lighter brown. Under parts of head and body, sides of head, including auriculars, and a narrow space above the eye, dirty yellowish-white, tinged with brown; purest on the side of head, the white very distinct in the loral region, and including the tuft of bristly feathers over the nostrils, excepting the tips of those in contact with the bill, which are blackish. The sides of the body and the under tail-coverts are tinged with yellowish-brown. The quills and tail-feathers are edged with the color of the back, without any whitish. Bill black. Feet lead-color.

Specimens from the West are larger, the colors all more strongly marked.

Habits. The Tufted Titmouse is a common and well-known species in the Southern States, from the seaboard to the Rocky Mountains. Its northern limits are in Pennsylvania, Missouri, and Kansas. Farther north than this its occurrence appears to be only occasional and accidental. The statement of Mr. Audubon that they are found in the Northern States, even to Nova Scotia, was evidently a mistake. They do not occur in Massachusetts, nor, so far as I am aware, have they been met with in any part of New England.

They are abundant in Northern Georgia, where, according to the observations of Dr. Gerhardt, they are among the first birds to breed, having fledglings fully grown as early as the first of May. Dr. Woodhouse found them very common in the Indian Territory, but none of the other exploring parties met with it farther west, where it is replaced by its kindred species.

It is perhaps the most abundant bird in Southern Illinois, where it is resident, being excessively numerous in winter, and in that season often a positive nuisance from their impertinent vehement scolding as they appear to follow the hunter in troops through the woods. In winter it is a constant inhabitant of the door-yards and shrubbery, particularly fruit-trees in the towns, where it is associated with the Carolina Chickadee (Parus carolinensis) and other winter birds, but exceeding them all in familiarity and boldness. (Ridgway.)

Mr. Nuttall, who never met with this bird north of Pennsylvania, found it very common in the winter and spring in the Southern States, where it displayed all the habits and uttered the usual notes of the family. In the dreariest solitudes of the Southern States these birds were his constant and amusing companions. Their sprightly movements and their varied musical talents made it even more peculiarly interesting at a time when all the other tenants of the forest were silent. The notes of this bird, which, when expressed by this writer on paper, seem only quaint and eccentric articulations, were characterized by him as lively, cheering, and varied, delivered with a delicacy, energy, pathos, and variety of expression to which it was far beyond the power of description to do justice.

These notes, at times, even partook of the high-echoing and clear tones of the Oriole. The usual song of this Titmouse is presented by Mr. Nuttall by the following characteristics: “Whip-tom-killy-killy-dāy-dāy-dā-it-tshica-dēē-dee,” varied with “Kāī-tee-did-did-did,” etc., etc. Later in the season, under the milder influences of spring, these Titmice pursued the insects from branch to branch, calling restlessly and with loud and echoing voices, peto-peto-peto, with frequent quaint variations too numerous to be repeated. Their song even consisted of successions of playful, pathetic, or querulous calls, never exhibiting any trills after the manner of the Warblers, yet the compass and tones of their voice, their capricious variety, and their general effect are described as quite as pleasing as the more exquisite notes of our summer songsters.

When wounded this Titmouse resists with great spirit any attempt to take him alive, but soon becomes tame and familiar in confinement, subsisting on seeds, broken nuts, etc. Impatient of restraint, it incessantly attempts to work its way out of its cage.

The general habits of these birds correspond closely with those of the large family to which they belong. They move usually in small flocks of from five to ten through the branches of trees and bushes in quest of insects, examine the cracks and crevices of the bark, hang on the under side of small branches, move sideways around the trunks of trees, probe the openings in acorns, pine-cones, nuts, etc., for its food, and retain apparently the family group until the spring, when they separate into pairs.

One of these birds kept in confinement by Dr. Bachman of Charleston was in the habit of hiding its food in the corner of its cage, in a small crevice, and of creeping at night into a small box, where it lay doubled up like a ball till the first light of the morning, when it resumed its restless habits.

The Tufted Titmouse passes its nights and days, when the weather is inclement, in the hollows of decayed trees or the deserted holes of the woodpeckers. In such places it also builds its nests. It has been known to excavate a hole for itself even in hard sound wood. Its nest is simply a rude lining of the selected cavity, composed of various soft and warm materials. In this are deposited from six to eight eggs. But a single brood is raised in a season. The young birds, as soon as they are fledged, hunt in company with their parents, and remain associated with them until the following spring. The eggs of this bird have a length of .75 of an inch and a breadth of .56. They are of a rounded oval in shape, and are thickly sprinkled with fine rust-colored dots, intermingled with a few larger markings of lilac, on a white ground.

Lophophanes atricristatus, Cassin

BLACK-TUFTED TITMOUSE; TEXAS TITMOUSE

Sp. Char. Crest very long and pointed (1.25 inches). Above ash-colored. A broad band on the forehead dirty white, rest of head above, with crest, black, tinged with ash on the sides. Color of the back shading insensibly into the dull ashy-white of the under parts. Sides of body pale brownish-chestnut. Female with the crest duller black. Iris dark brown. Length, about 5.25 inches; wing, 3.00.

Hab. Valley of Rio Grande, south, into Mexico. San Antonio. Texas. Vera Cruz, Sclater.

This species is not rare in Texas, where it has been noticed as far east as San Antonio.

Habits. So far as known, the Black-crested Titmouse is restricted in its distribution to the valley of the Rio Grande, including portions of Mexico and Western Texas. It was first met with in the latter State by John W. Audubon, and described by Mr. Cassin in the Proceedings of the Philadelphia Academy.

In its general appearance and in all its habits it is mentioned as having so close a resemblance to the common Tufted Titmouse as to be hardly distinguishable from that bird. Dr. Woodhouse met with this species near San Antonio, Texas, in March, 1851. While his party was encamped on the Rio Salado he observed these birds busily engaged in capturing insects among the trees on the banks of the stream. Like all the members of this family, it was incessantly in motion and very noisy. Later in the season, on the 8th of May, the same party, when encamped on the Quihi, again found this species very abundant among the oaks. The young males, then fully grown, closely resembled the adult females, both wanting the black crest that distinguishes the mature male. He afterward noticed this species occurring at intervals along his route as far as the head waters of the Rio San Francisco in New Mexico. He observed it almost exclusively among the trees that bordered streams of water. The females and the young males invariably had crests of the same cinereous color as their general plumage, but in the latter slightly tinged with brown. They occurred in small parties, were very lively and sociable in their habits, and in their general appearance and even in their notes so very closely resembled the Eastern species as, at a short distance, to be hardly distinguishable from it.

Dr. Heermann, in his report on the birds of Lieutenant Parke’s survey, mentions having first observed this species near Fort Clarke, in Texas, where it was very abundant. He describes it as sprightly and active in its movements, searching with great assiduity for insects in the crevices of the bark and among the branches of trees. While thus engaged it keeps up a chattering note, varied with an occasional low and plaintive whistle. Its habits appeared to him to resemble most those of the common Parus atricapillus. Dr. Heermann states that it builds its nest in the hollow of trees, and that it lays from twelve to sixteen eggs. He does not, however, say that he ever met with its eggs, nor does he give any description of them. The nest, he states, is composed of fine dry grasses, feathers, wool, mosses, etc.

General Couch’s description of this species and its habits is very similar. He observed it in the province of New Leon, in Mexico, where he found it very abundant along the San Juan into the Sierra Madre. He describes it as a very lively bird, with a very perfect whistle of a single note.

Mr. Henry A. Dresser sought very diligently for its nest and eggs near San Antonio and Houston, in Texas, where he found the bird very common, and where he was sure many pairs remained to breed, but its nest was very hard to find, and the birds very wary. He succeeded in finding one nest, in a hollow tree, near the head springs of the San Antonio River, but it contained young. The nest he does not describe, nor does he mention the number of young it contained.

Lophophanes inornatus, Cassin

GRAY-TUFTED TITMOUSE; CALIFORNIA TITMOUSE

Parus inornatus, Gambel, Pr. A. N. Sc. Phil. Aug. 1845, 265 (Upper California).—Ib. J. A. N. Sc. new ser. I, 1847, 35, pl. vii. Lophophanes inornatus, Cassin, Ill. 1853, 19.—Baird, Birds N. Am. 1858, 386; Review, 78.—Sclater, Catal. 1861, 14, no. 88.—Elliot, Illust. I, pl. iii.—Cooper, Birds Cal. 1, 42.

Sp. Char. Crest elongated. Color above olivaceous-ashy, beneath whitish. Sides of body and under tail-coverts very faintly tinged with brownish, scarcely appreciable. Sides of head scarcely different from the crown. Forehead obscurely whitish. Length, 5 inches; wing, 2.55.

Hab. Southern United States, from Rocky Mountains to Pacific; Western Nevada (Ridgway). W. Arizona (Coues).

The bill and feet of this species are lead-color. The third, fourth, and fifth quills are longest; the third and eighth about equal; the second is shorter than the shortest primaries. The lateral tail-feathers are a little shorter than the others.

A specimen from Fort Thorn has the crest longer than in other specimens before me, measuring 1.35 inches from base of bill to its tip. This may be a characteristic of the male, the sexes being otherwise alike.

Habits. The Gray Titmouse belongs essentially to the Pacific coast, coming eastward only as far as the banks of the Rio Grande in Texas. It was first discovered and described by Dr. Gambel, in his Birds of California. It has since been met with not only throughout California, but also in all the southern portions of the Rocky Mountains, in New Mexico, and from Mimbres to the Rio Grande.

Dr. Woodhouse met with this species in the San Francisco Mountains, near the Little Colorado River, New Mexico. He found it very abundant, feeding among the tall pines in company with the Sitta pygmæa, S. aculeata, and Parus montanus.

Dr. Gambel first noticed this species near Monterey on the 20th of November. It was flitting actively about among the evergreen oaks of that vicinity in company with large flocks of several kindred species. They were all in restless activity, searching every branch for insects. As well as he could distinguish its notes among those of the busy throng in the midst of which he observed it, they appeared to resemble very closely those of the common P. atricapillus. Upon his following it up, it would utter a loud scolding outcry, erect its high and pointed crest, and appear as angry as possible at the intrusion. He found it very common, frequenting tall bushes in small flocks, searching branches of low trees, uttering weak and slender cries, resembling the syllables tsēē dāy-dāy.

Dr. Heermann found it one of the most common of the birds of California, where it is resident throughout the year. He describes their notes as possessing an almost endless variety, so much so that he was repeatedly prompted to follow it as a new species. He met with a nest of this bird in a deserted woodpecker’s hole, which contained young.

Dr. Cooper has met with this species in February near San Diego, but not on the Colorado. They seem to prefer the evergreen-oak groves toward the middle of the State, but are not found in the higher Sierra Nevada. They are residents throughout the year in the evergreen oaks near San Francisco. He adds that they are seen in small parties, scattered about the trees, and calling to each other with a variety of sweet and loud notes, some of which are said to equal those of our best singers. It also has certain powers of imitation like the Eastern crested species and the same cry of pēto-pēto.

It feeds on acorns as well as insects, and often goes to the ground in search of them. It cracks the acorns with its bill, and hammers at bark and decayed wood with the industry of a woodpecker.

Mr. Ridgway met with this species among the pines of the eastern slope of the Sierra Nevada, but nowhere in abundance. Among the cedars it was almost the only bird seen. He describes its manners as greatly resembling those of the other species. Its notes, though differing from those of the Eastern L. bicolor, being weaker and less distinct, retain its vehement and characteristic manner of utterance.

Hein. 1850, 1851, 90.

Sp. Char. Central portion of crest ash, encircled by black, commencing as a frontal band, and passing over the eye. Chin, throat, and a line from behind the eye and curving round the auriculars to the throat (bordered behind by white), as also some occipital feathers, black. A white line from above the eye margining the crest, with the cheeks below the eye and under parts generally white. A black half-collar on the nape. Upper parts of body ashy. Length, about 4.50; wing, 2.50.

Hab. Southern Rocky Mountains of United States, and along table-lands through Mexico, to Oaxaca (high regions, Sclater). Orizaba (Alpine regions, Sum.).

Habits. Wollweber’s Titmouse, so far as its distribution is known, is a bird of Western Texas, the high table-lands of Mexico, and of the whole of New Mexico. It was described by Bonaparte and by Cassin nearly simultaneously, in 1850. It bears a very close resemblance to the Lophophanes cristatus of Europe.

Although comparatively nothing is known in reference to the specific habits of this species, they may be very readily inferred from those of the other members of this genus, whose characteristics are all so well marked and so uniform. Dr. Kennerly is the only one of our naturalists who has mentioned meeting the species in its living form. In his Report upon the Birds of Lieutenant Whipple’s Survey he states that he found it in the thick bushes along the Pueblo Creek. Wherever noticed it was constantly in motion, hopping from twig to twig in search of its food. He also found it among the pines of the Aztec Mountains. No mention is made of its nest or eggs, and its nidification remains to be ascertained.
