Part 18

While a few of these birds are resident of the Northern States, they are, to a considerable extent, of migratory habits. Wilson observed them leaving in large numbers for the Southern States in October, and returning again in April. On the 20th of May, 1867, the writer observed a small flock in Eastern Massachusetts, evidently just arrived from the South. They were apparently fatigued and hungry, and paid no attention to the near presence of workmen engaged in setting bean-poles. They visited and carefully examined each pole, and bored holes into several in search of hidden larvæ, often within a few feet of persons at work.

While on the Pacific coast they are said to prefer the forests of deciduous trees, and to be rarely found in the dark evergreen forests, in the Eastern States they seem to be particularly fond of the seeds of pine-trees, and in the winter are seldom found in the woods of deciduous trees.

They feed in pairs and climb about in all directions, usually in company with the white-breasted species, Chickadees, and the smaller Woodpeckers. They are restless and rapid in their motions, and have a voice at least an octave higher than any other of this family. The note is a monotone, and is unmusical. Mr. Nuttall represents their cry as consisting of three syllables, represented by _dāy-dāy-dāit_, and compares it to the sound of a child’s trumpet.

Those wintering at the North occasionally visit farm-yards and orchards, and examine the eaves of outbuildings for food.

Audubon found this species more plentiful in the woods of Maine and Nova Scotia than anywhere else. He never met any south of Maryland, saw none in Newfoundland, and only met with one in Labrador. At Eastport he found a pair breeding as early as the 19th of April, before the Bluebirds had made their appearance, and while ice was still remaining on the northern exposures. An excavation had been made in a low dead stump, less than four feet from the ground, both male and female birds working by turns until they had reached the depth of fourteen inches. The eggs, four in number, were of a white ground-color, tinged with a deep blush when fresh, and sprinkled with reddish dots. They raise but a single brood in a season.

C. S. Paine, of East Bethel, Vt., found a nest of this species about the middle of May, in a small beech-tree, the excavation having been made at the height of twelve feet from the ground. The hole was about as large as that made by the Downy Woodpecker. When first noticed, the bird was looking out of the hole. Having been started out, she flew to a limb close by and watched the party some time. When she flew back, she buzzed before the hole in the manner of a Humming-Bird, and then darted in. While Mr. Paine was looking on, the male came several times to feed his mate, who would meet him at the opening with a clamorous noise, to receive his bounty. The nest contained five eggs.

In Western Massachusetts, Mr. Allen speaks of this species as chiefly a winter resident, appearing the first week in October, and leaving the last of April.

The eggs of this species measure .62 by .48 of an inch, and are of an oblong-oval shape. Their ground-color is a clear crystal white, marked principally about the larger end with a wreath of purple and roseate markings.

Sitta pygmæa, VIG.

PIGMY NUTHATCH.

_Sitta pygmæa_, VIGORS, Zoöl. Beechey’s Voy. 1839, 25, pl. iv.—AUD. Orn. Biog. V, 1839, pl. ccccxv.—IB. Birds Am. IV, pl. ccl.—REICH. Handb. 1853, 153, tab. dxiv, figs. 3365, 3366.—NEWBERRY, P. R. R.

SP. CHAR. Above ashy-blue; head and upper part of neck greenish ashy-brown, its lower border passing a little below the eye, where it is darker; nape with an obscure whitish spot. Chin and throat whitish; rest of lower parts brownish-white; the sides and behind like the back, but paler. Middle tail-feather like the back; its basal half with a long white spot; its outer web edged with black at the base. Length about 4 inches; wing, 2.40.

HAB. Western and Middle Provinces of United States; south to Xalapa.

This species is closely related to _Sitta pusilla_ of the Southern States. The brown of the head has, however, an olivaceous-green tinge not seen in the other; the white spot on the nape less distinct. The middle tail-feather has its basal half white and the outer web edged with black at the base. This black edging is never seen in the other, and the white patch is reduced to a faint trace, only visible in very highly plumaged specimens.

HABITS. This diminutive species of Nuthatch is found throughout our Pacific coast and on the western slope of the Rocky Mountains, from Washington Territory to Southern California. It is also to be found in New Mexico, and specimens have been procured from Mexico.

Dr. Kennerly found them quite abundant in the Sierra Madre and San Francisco Mountains, even as high up as the snow-line, seeking their insect food among the tops of the lofty pines. Dr. Newberry frequently met with these Nuthatches in the most wooded places on his route, where water was near and any considerable amount of animal life visible. He, however, never met with them in the forests of yellow pines. Dr. Gambel mentions their almost extraordinary abundance, in the winter months, in Upper California. Around Monterey, at times, the trees appeared almost alive with them, as they ran up and down and around the branches and trunks, uttering their monotonous and querulous cries. Their note he describes as a repeated whistling _wit-wit_. When one utters this cry, the rest join in. They also have a whistling trill while they are busily searching the tree in every part, and they never leave till they have pretty thoroughly searched every crack.

Dr. Cooper only met with this Nuthatch in the open pine-forests about Fort Colville, near the 49th parallel. They were associated in small flocks about the 20th of October, when there were heavy frosts at night. The chirping noise they made resembled the cries of young chickens. Their habits were very similar to those of the _Psaltriparus minimus_.

Mr. J. K. Lord found this Nuthatch an abundant bird along the entire length of the boundary line from the coast to the Rocky Mountains. It was also common on Vancouver Island. They were seen in large flocks in company with the Chickadees, except during the nesting-time, which is in June. A few were winter residents at Colville, but the greater number left in November. He describes it as a very active bird, always on the move. After nesting they congregate in large flocks and move about from tree to tree, twittering a low sweet note as if singing to themselves, now climbing back downwards along the under sides of the topmost branches of tall pines, searching into every crevice for insects, or, descending to the ground, clinging to the slender flower-stalks for other insects. They nest in June, make a hole in the dead branch of a pine, and deposit their eggs on the bare chips of the wood. This account does not agree with the experience of California ornithologists, who have found a loose nest within the excavation.

Mr. Ridgway found this Nuthatch abundant among the pines of the Sierra Nevada, in the vicinity of Carson City. They were found generally in pairs. Its note is said to greatly resemble the vociferous peeping of some of the small Sandpipers, being sharp, loud, and distinct, and vigorously and continuously uttered, whether climbing or flying. He found it exceedingly hard to discover this bird among the branches, or even when flying, owing to the swiftness and irregularity of its flight. When the female of a pair had been killed, the male bird was extremely loud in his lamentations. Diminutive as this bird is, Mr. Ridgway states that it is also the noisiest of all the feathered inhabitants of the pines, though it is less active in the pursuit of insects than the larger species.

Nests of this bird obtained near Monterey appear to be as well made as those of any of this genus, lining the cavity in which they are placed and conforming to it in size and shape, the materials sufficiently interwoven to permit removal and preservation, and warmly constructed of feathers, wool, vegetable down, hair, and the silky efflorescence of seeds.

Their eggs, seven in number, resemble those of the _S. canadensis_, but are of smaller size and a little more pointed at one end. Their ground-color is crystalline-white. This is covered more or less thickly with red spots, most numerous at the larger end. Their measure varies from .65 by .50 to .60 by .47 of an inch. The first eggs of this bird brought to the notice of naturalists were procured at Fort Crook on the Upper Sacramento of California, and not far from Mount Shasta, by Sergeant John Feilner, U. S. A., forming part of a very extensive collection of birds and eggs transmitted by him to the Smithsonian Institution. Promoted to a lieutenancy for gallant conduct, this gentleman finally attained the rank of captain of cavalry, and was killed by the Sioux during an exploring expedition into Dacotah under General Sully.

SP. CHAR. Above ashy-blue; top of head and upper part of neck rather light hair-brown, divided on the nape by white. Eye involved in the brown, which is deeper on the lower border. Beneath muddy-whitish; sides and behind paler than the back. Middle tail-feathers almost entirely like the back. Length of female, 4 inches; wing, 2.50.

HAB. South Atlantic and Gulf States. Ohio! KIRTLAND.

HABITS. The Brown-headed Nuthatch has a much more restricted distribution than the other members of this family in this country. The specimens in the Smithsonian Museum are chiefly from Georgia. Wilson met with it in Virginia, and states that it is found in the other Southern States. I have received its eggs from Cheraw, S. C., and from Florida.

Wilson’s description of its habits makes them almost identical with those of _Sitta canadensis_, while its notes are more shrill and chirping. Like that bird, it is very fond of the seeds of the pines. Wherever found, it is a constant resident, and does not migrate.

Audubon states that this bird never goes farther north than Maryland, and that it is the most abundant in Florida, Georgia, and the Carolinas. In Louisiana it is rare, and it is not found in Kentucky. Its notes, he states, are several octaves higher than those of the _carolinensis_, and more shrill, and at least an octave and a half higher than those of the _canadensis_.

Although apparently preferring pines and pine barrens, it by no means confines itself to them, but is not unfrequently seen on low trees and fences, mounting, descending, and turning in every direction, and with so much quickness of motion as to render it difficult to shoot it. It examines every hole and every crevice in the bark of trees, as well as their leaves and twigs, among which it finds abundance of food at all seasons. During the breeding-season they go about in pairs and are very noisy. Their only note is a monotonous cry, described as resembling _dĕnd, dĕnd_. Mr. Audubon further states that when the first brood leaves the nest, the young birds keep together, moving from tree to tree with all the activity of their parents, who join them when the second brood is able to keep them company. In Florida they pair in the beginning of February, having eggs as early as the middle of that month. In South Carolina they breed one month later. Their nest is usually excavated by the birds themselves in the dead portion of a low stump or sapling, sometimes only a few feet from the ground, but not unfrequently at the height of thirty or forty feet. Both birds are said to work in concert with great earnestness for several days, until the hole, which is round, and not larger at the entrance than the body of the bird, is dug ten or twelve inches deep, widening at the bottom. The eggs, according to Mr. Audubon, are laid on the bare wood. This, however, is probably not their constant habit. The eggs, from four to six in number, and not much larger than those of the Humming-Bird, have a white ground, thickly sprinkled with fine reddish-brown dots. They are said to raise two, and even three, broods in a season. According to the observations of the late Dr. Gerhardt of Northern Georgia, the Brown-headed Nuthatch breeds in that part of the country about the 19th of April.

The eggs of this Nuthatch are of a rounded oval shape, measuring .60 by .50 of an inch. Their white ground-color is so completely overlaid by a profusion of fine dottings of a dark purplish-brown as to be entirely concealed, and the egg appears almost as if a uniform chocolate or brown color.

FAMILY CERTHIADÆ.—THE CREEPERS.

CHAR. Primaries ten; first very short; less than half the second. Tail long, wedge-shaped, the feathers stiffened and acute. Bill slender, much compressed and curved. Outer lateral toe much longest; hind toe exceeding both the middle toe and the tarsus, which is scutellate anteriorly and very short. Entire basal joint of middle toe united to the lateral.

GENUS CERTHIA, LINN.

_Certhia_, LINNÆUS, Syst. Nat. ed. 10th, 1758, 112. (Type, _C. familiaris_.) (See REICHENBACH, Handbuch, I, II, 1853, 256, for a monograph of the genus.)

[Line drawing: _Certhia americana._ 827 ♂]

GEN. CHAR. Plumage soft and loose. Bill as long as head, not notched, compressed; all its lateral outlines decurved. Nostrils not overhung by feathers, linear, with an incumbent thickened scale, as in _Troglodytes_. No rictal bristles, and the loral and frontal feathers smooth, without bristly shafts. Tarsus scutellate anteriorly, shorter than middle toe, which again is shorter than hind toe. All claws very long, much curved and compressed; outer lateral toe much the longer; basal joint of middle toe entirely adherent to adjacent ones. Wings rather pointed, about equal to the tail, the feathers of which are much pointed, with stiffened shafts. Primaries ten; first less than half the second. Nest in holes of trees; eggs white, sprinkled with reddish.

Of the _Certhiadæ_ but one genus belongs to America,—_Certhia_, with its one small species of considerable variability with locality. The characters above given include both family and generic characters, derived from this one genus. This is readily distinguished by the decurved, compressed bill; absence of notch and bristles; exposed linear nostrils with incumbent scales; connate middle toe, very long claws, short tarsi, pointed and stiffened tail-feathers, etc.

The American and European varieties (they can scarcely be called species) resemble each other very closely, though they appear to be distinguished by such differences as the following:—

The two European races, _C. familiaris_ and _C. costæ_, both differ from all the American varieties in having the crissum scarcely tinged with yellowish. _C. familiaris_ is more ashy beneath than any others, and _C. costæ_ is purest white beneath of all. Nearest _C. familiaris_, in the American series, as regards tints of the upper parts, are the Pacific coast specimens of _C. americana_,—while the latter are most like the Atlantic region specimens of the same. _C. mexicana_ is to be compared only with the North American forms, though it is the only one approaching _familiaris_ in the ashy lower parts.

_C. familiaris_ is at once separated from the rest by having the tail shorter than the wing.

_C. costæ_ is almost precisely like Eastern specimens of _C. americana_ in colors, but is absolutely pure white below, and without the distinctly yellowish crissum of the American bird. The bill and claws, however, are considerably longer than in Eastern _americana_, though their size is almost equalled by those of Western specimens; the colors are, however, more decidedly different.

There is never any deviation from the generic _pattern_ of coloration; but the variation, _among individuals of each form_, in length of the bill and claws, as well as the tail, is remarkable.

SP. CHAR. Bill about the length of the head. Above dark brown, with a slightly rufous shade, each feather streaked centrally, but not abruptly, with whitish; rump rusty. Beneath almost silky-white; the under tail-coverts with a faint rusty tinge. A white streak over the eye; the ear-coverts streaked with whitish. Tail-feathers brown centrally, the edges paler yellowish-brown. Wings with a transverse bar of pale reddish-white across both webs. Length, 5.50; wing, 2.60; tail, 2.90. (No. 827.)

_Young._ (5945, Steilacoom, W. T.; Dr. J. S. Cooper.) Resembling the adult, but streaks above indistinct, and the feathers there tipped indistinctly with blackish; the rufous restricted to the upper tail-coverts. Breast and jugulum with very minute blackish wavings or indistinct bars.

HAB. Whole of United States, to Red River Settlement.

Specimens from the far west are purer white beneath, much as in _costæ_, but those from the northwest coast have the white tinged with light rusty. Though purer white below, these specimens are much browner above than Eastern ones,—sometimes more so than in _familiaris_, but then there is the yellowish crissum never seen in this “species,” and the proportions are quite different. Thus it will be seen the _C. americana_ may always be distinguished from the other forms; when most resembling _costæ_ in the grayish tints of the upper plumage (as in Eastern examples), the lower parts are less purely white, and the bill and claws smaller; when like it in the proportions and pure white of the lower parts (as in Western specimens), the colors above are altogether more brown. The yellowish crissum of _americanus_ will also distinguish them. Though often resembling _familiaris_ in the colors of the upper parts, the latter may always be distinguished by its ashy lower parts without yellowish crissum, the shorter tail, with its less acute feathers, and stouter bill.

_C. mexicanus_ is still more different in colors, for which see that variety.

HABITS. Our common Creeper, so closely resembling the Creeper of Europe as by many to be supposed identical with it, is distributed over the whole of North America, from the Gulf of Mexico to high northern latitudes. At different seasons it may be found in every one of the several States and Territories, yet it is never very abundant. The Smithsonian possesses specimens from various parts of the country, from Georgia to Fort Steilacoom on the Pacific, but of these none appear to have been secured during the period of reproduction. Dr. Heermann found them very common in the more mountainous districts of California. Dr. Cooper found these birds abundant in the forests of Washington Territory, but difficult to detect from the similarity of their color to that of the bark over which they crept. They were apparently constant residents in that Territory. Dr. Suckley, who obtained several specimens of this species in the oak groves in the vicinity of Fort Steilacoom, states that in their habits the Western birds resemble those of the Atlantic States.

Mr. Ridgway found this Creeper inhabiting both the pine forests of the Sierra Nevada, where it was the more common, and also, in winter, among the willows of the river valleys. He did not meet with it east of the Truckee River, nor until he had reached the Wahsatch Mountains.

Dr. Woodhouse found the Brown Creeper generally distributed throughout the Indian Territory, Texas, New Mexico, and California, and adds that it was especially abundant in the San Francisco Mountains of New Mexico.

Dr. Cooper states that he has met with this form in the winter throughout the higher mountains and among the Coast Range as far south as Santa Cruz. He found them chiefly frequenting the coniferous trees, creeping up and down their trunks and branches, searching for insects in their crevices, and so nearly resembling the bark in their general color, that they can be detected only with great difficulty, except when in motion.

He adds that their notes are shrill and wiry, and are often heard when the bird is scarcely visible, without a careful search, their cry appearing to be from a greater distance than the real performer. In March, Dr. Cooper heard them giving out a faint but sharp-toned song, resembling that of a Wren. If Dr. Cooper is correct in his account of the notes, they do not correspond with those of our Eastern bird.

Dr. Kennerly, in his Report on the birds observed by him near the 35th parallel, states that he found our common Creeper very abundant among the rough-barked cedars in the Aztec Mountains. It usually attracted notice, and its place of retreat was discovered, by his hearing its quick and sharp notes. A close and careful search generally enabled him to perceive it proceeding leisurely upward and downward, in straight or spiral lines, toward the top of the tree, dodging dexterously to the opposite side from the observer, and only resuming its occupation when assured of solitude and safety.

The observations of Dr. Kennerly, if they are to be received as characteristic of the Western Creepers, do not correspond with those of our Eastern birds, as far as we have observed them. None of our birds are more easily approached, and when they are pursuing their search for food, none are more regardless of observation. The statement that our Creeper, when watched, moves to the opposite side of the tree from the looker-on, has found a certain currency in our books. We are, however, of the opinion that this is owing to its restless activity, prompting it to constant changes of place and position, and not to its timidity or caution. We have uniformly found them either unconscious or regardless of our near presence.

They are solitary in their habits, and frequent, especially in the summer, deep woods, searching for their favorite food in high places where it is difficult to reach them, but this is no necessary evidence of their shyness. They often hunt for their food in very exposed places, with equal courage and recklessness. It is an active, restless bird, associating with Titmice and the smaller Woodpeckers, moving with great rapidity from side to side and from place to place. They breed in hollow trees, in the deserted holes of the Woodpeckers, and in the decayed stumps and branches of trees. Their nest is a loose aggregation of soft, warm materials, not interwoven, but simply collected with regard to no other requisite than warmth.
