In the other section of the genus the relation between arizonæ and sordida is a parallel to that between Cyanura macrolopha and C. coronata; the southern forms (sordida and coronata) differing principally in the greater intensity and prevalence or amount of the blue. The relations of couchi and ultramarina to the two above mentioned are yet obscure, owing to the small material at command,—there being only two specimens of the former, and none of the latter, in the National Museum at Washington.

Sp. Char. Tail much graduated; lateral feathers nearly 1.50 inches shortest. Tail an inch longer than the wings. Above blue, including scapulars; interscapular region and back brownish-ash, the former lighter. Forehead and sides of the crown, including the nasal feathers, hoary white. Sides of head and neck blue; the former tinged with blackish, the latter sending a streaked collar of the same entirely across the breast; region anterior to this collar dirty white, streaked on the edges of the feathers with blue; rest of under parts dirty whitish-brown; under tail-coverts blue, the tibia tinged with the same. Length, 11.00; wing, 4.50; tail, 5.70; tarsus, 1.45.

Hab. Florida only, and quite local.

Habits. This beautiful species appears to be exclusively confined to the peninsula of Florida, and there is no authentic evidence that it has ever been found outside of the limits of that State. The statement of Bonaparte, that these birds are found in the States of Louisiana and Kentucky, has never been confirmed, and Mr. Audubon, who was for many years a resident of both States and familiar with the birds of each, was very positive the statement was without foundation. It has never been observed even in Georgia or Alabama, and Mr. Nuttall states that it is not found in any part of West Florida.

Mr. Allen, in his recent paper on the winter birds of East Florida, speaking of this species, states that it is numerous in the scrub, but does not appear to frequent the pine woods, the hummocks, or the swamps. He saw none along the St. John’s, except at Blue Springs, but they occur in numbers a few miles back from the river.

Dr. Bryant, in his Notes on the birds of Florida, mentions that this species is tolerably plentiful in the vicinity of Enterprise. He regarded it as exceedingly interesting on account of its limited geographical distribution. With no apparent obstacle to its movements, it is yet confined to a small part of the peninsula of Florida, its area of distribution north and south not exceeding three degrees of latitude, if so much. He saw none north of St. Augustine, and none south of Jupiter’s Inlet. So far as he observed them, they were exclusively confined to the growth of scrub-oak, which in many places is so entangled with creeping plants that it is impossible to walk through without cutting a path. This growth is generally found on elevated ridges running parallel to the sea-coast. The most extensive of these, near Enterprise, is about three miles wide, and eighty feet above the lake.

The flight of this species is said by Mr. Audubon to be performed at a short distance from the ground, and to consist either of a single sailing sweep, as it passes from one tree to another, or of continuous flappings with a slightly undulating motion, in the manner of the Canada Jay. Its notes are described as softer than those of the Blue Jay, and more frequently uttered. Its motions are also quicker and more abrupt. Its food is said to consist of snails, which it collects on the ground, insects, and various kinds of fruits and berries. It is also charged with being very destructive of eggs and young birds.

The Florida Jay is said to be easily kept in confinement, feeding readily on dried or fresh fruit and the kernels of various nuts, and soon appears to be reconciled to its loss of liberty. It secures its food between its feet, and breaks it into pieces before swallowing it. In this way it feeds on the acorn of the live-oak, snails, and the seeds of the sword-palmetto.

The nest of this Jay is formed of dry sticks, placed across each other, and, although rounded in form, is so lightly made that the birds may be seen through its interstices. It is lined with fibrous rootlets. Only one brood is raised in a season. Audubon’s descriptions of its eggs are inaccurate, and only applicable to those of the Blue Jay.

Mr. Audubon observed a pair of these birds in confinement in New Orleans. They were fed upon rice and dry fruit. At dessert they were allowed their liberty, when they would fly to the table, feed on the almonds given them, and drink claret diluted with water. They attempted to mimic various sounds, but did so very imperfectly.

Mr. Nuttall states that at the approach of winter these birds retire to the south of St. Augustine. He regards their voice as less harsh than that of the Blue Jay, and states that they have a variety of notes, some of which are probably imitations, and are said to resemble the song of the Wood Thrush and the calls of the common Jay.

An egg of the Florida Jay before me is of a rounded oval shape, being nearly equally obtuse at either end. The ground-color is a light bluish-gray, marked almost exclusively at the larger end with a few small spots of a light rufous-brown. It has no near resemblance to the eggs of the California Jay, nor to those of any other Jay that I have seen. It measures 1.05 inches by .80.

In its flight and action, Dr. Bryant thought the Florida Jay resembled the Mocking-Bird. It has none of the restless, suspicious manner of the Blue Jay. He never heard it utter more than a single note, this being much softer than the usual cry of the Blue Jay; its song he regarded as rather monotonous. It seldom flies more than a short distance at a time, and seems to trust for protection to the difficulty of access to its abode. It also evinces a great partiality for particular localities. Generally only a single pair is seen at a time, though in one place he has seen three pairs together. It is not fond of civilization, and is seldom known to frequent the vicinity of dwellings.

A nest found by Dr. Bryant on the 15th of April was built in a scrub-oak about three feet from the ground. It was made of small twigs, compactly and carefully lined with fibres of the dwarf palmetto, that had apparently been brought a distance of half a mile. The cavity measured about five inches in breadth and one and a half in depth. The nest contained three eggs of a light blue, sparingly sprinkled with rufous, the spots being larger and more numerous towards the larger end. Another nest, found a few days later, contained five eggs of a more neutral tint, with the spots darker, larger, and more evenly distributed.

Sp. Char. Width of bill at base of lower mandible rather more than half the length of culmen. Lateral tail-feathers about an inch the shortest. Tail an inch longer than the wings. General color above, including the surface of the wings, bright blue, without bars. The whole back, including to some extent the scapulars, brownish-ash, very faintly glossed with blue in the adult. À streaked white superciliary line from a little anterior to the eye as far as the occiput. Sides of the head and neck blue, the region around and behind the eye, including lores and most of ear-coverts, black. The blue of the sides of the neck extends across the forepart of the breast, forming a crescent, interrupted in the middle. The under parts anterior to the crescent white, the feathers edged with blue; behind it dull white; the sides tinged with brown. Length, 12.25; wing, 5.00; tail, 6.15; tarsus, 1.55. (No. 2,841.)

Hab. Pacific Province from Columbia River to Cape St. Lucas; Carson City, Nevada (Ridgway).

Cyanocitta californica.

 

Specimens from Cape St. Lucas are rather smaller and perhaps whiter beneath than elsewhere; those from the eastern slope of Sierra Nevada are very large. Upon a careful comparison, we find that the supposed specimens of C. californica in the Smithsonian collection from Mexico (Orizaba, etc.) constitute a quite different form, characterized by very indistinct superciliary white and bluish edges to throat and jugular feathers, and especially by the lengthened wings, which average 5.75 inches instead of 5.00. In general respects the resemblance, as suggested by Sclater, is to californica, and not to woodhousei. The dorsal patch is very distinct.


PLATE XL.


1. Cyanocitta californica. ♂ Nev., 56642.


2. Cyanocitta californica. var. sumichrasti. ♂ Orizaba, 42129.


3. Cyanocitta woodhousii. ♂ Nev., 53647.


4. Cyanocitta floridana. ♂ Fla., 13734.


One Mexican specimen (8,465 from Real del Monte?), presented by Mr. John Gould, differs again in having the dorsal patch obscured by a bluish wash; an unusual amount of blue edging to the throat and jugular feathers, and a dull brownish tinge to the belly. It almost suggests the possibility of a hybrid form between sumichrasti and ultramarina.

Habits. The California Jay appears to be a Pacific coast species, occurring from the Columbia River southward to Cape St. Lucas, but not found in the interior at any considerable distance from the coast. Mr. Ridgway speaks of it as the Valley Jay of California, having been observed by him in abundance only among the oaks of the Sacramento Valley, the brushwood of the ravines, and the scattered pines of the foot-hills along the western base of the Sierra Nevada. It was also quite common, in April, in the vicinity of Carson City, where he found it breeding. Its notes and manners, he adds, are very similar to those of the Woodhouse Jay, belonging to the wooded regions of the interior, but the shrill cries of this species are even more piercing. There is, moreover, something in its appearance, caused by the sharp contrast of the bright blue, the light ash, and the pure white colors, by which it may be distinguished at a glance from the more uniformly colored woodhousei.

Dr. Heerman speaks of it as frequenting to some extent the same districts as Steller’s Jay, but also found in greater abundance throughout the valleys. He likewise describes it as noisy, alert, and cunning in its habits, wild and wary, and yet often seeking the habitations of man, near which to rear its young, drawn thither by the abundance of food found in such localities. Their nests, he states, are built in a thick-leaved bush, or on the lower branches of an oak, at but little height from the ground. They are constructed of twigs, and are lined with fine rootlets. The eggs, four in number, are, he says, emerald-green in color, profusely dotted with umber-brown spots.

Dr. Newberry states that he found the trees and the thickets bordering the streams in the valleys the favorite haunts of the California Jay. As his party ascended among the evergreen forests of the higher grounds, and passed northeasterly from the Sacramento Valley, these birds were no longer met with, and long before reaching the Oregon line they lost sight of it altogether. Nor did they meet with it again until their return to California. This Jay, he adds, has all the sprightliness and restlessness of the family, but is less noisy, and its notes are far more agreeable than those of Steller’s Jay, by which it is replaced at the north.

The Smithsonian Museum has a specimen of this species obtained on the Columbia by Townsend, and Mr. Nuttall mentions that early in October, on arriving at the forests of the Columbia, near Fort Vancouver, he met with it in company with Steller’s Jay. They were breeding in the dark pine woods, and by the 15th of June they were feeding their fully fledged young. He also states that they were found as far north as Fraser’s River, migrating to the south at the approach of winter. Without questioning the correctness of this statement, it is worthy of mention that these birds have not been met there by more recent collectors, and that Dr. Newberry nowhere met with them in Oregon. Dr. Cooper suggests that, since then, the increased severity of the winters may have driven them permanently farther south.

Mr. Nuttall describes its habits as very much like those of the Blue Jay. It usually flies out to the tops of the tallest pines, jerks its tail, and perches playfully on some extreme branch, where, as if in anger, it calls woit, woit-woit, with an occasional recognition note of twee-twee. When pursued, it retreats to the shade of the loftiest branches. It feeds on insects, acorns, which it breaks up, and pine seeds. He describes it as a graceful, active, and shy bird, with a note much less harsh and loud than that of Steller’s Jay.

Dr. Cooper remarks that this species is one of the most common and conspicuous of the birds of the State of California. They frequent every locality in which oak-trees are found, even within the limits of large towns, where they enter gardens and audaciously plunder the fruit. They have all the usual cunning of their tribe, and when alarmed become very quiet, and conceal themselves in the thick foliage. They are usually noisy and fearless, and their odd cries, grotesque actions, and bright plumage make them general favorites in spite of their depredations. They are also said to have a talent for mimicry, besides notes to express their various wants and ideas.

They breed abundantly throughout the western parts of California, and construct a large and strong nest of twigs, roots, and grass. These are placed in a low tree or bush. They lay about five eggs, which Dr. Cooper describes as dark green marked with numerous pale brown blotches and spots, and measure 1.80 by 1.04 inches. At San Diego he found these eggs laid as early as April 5.

This Jay inhabits the Coast Range of mountains to their summit, south of San Francisco, and the Sierra Nevada as far as the oaks extend, or to an elevation of from 1,000 to 5,000 feet. Dr. Cooper saw none on the east side of the Sierra Nevada in latitude 39°.

He describes their flight as slow and laborious, on account of their short wings, and states that they never fly far at a time. He also accuses them of being very destructive to the eggs of smaller birds, hunting for them in the spring, and watching the movements of other birds with great attention.

Mr. Xantus found these birds very abundant at Cape St. Lucas, being, like all the other resident species there, much smaller than those occurring in more northern localities. Their habits are said to be very much the same.

This species was taken in winter near Oaxaca, Mexico, by Mr. Boucard.

Four eggs of this species from different parts of California present the following measurements: 1.20 × 0.85; 1.10 × 0.80; 1.13 × 0.80; 1.05 × 0.80. The measurements given by Dr. Cooper we are confident must be a mistake. Their ground-color is a bright, but not a dark, emerald-green; and they are marked and blotched with faint purplish-brown, and deeper spots of dark umber. These spots are sparingly distributed, and are chiefly about the larger end. In one they are wholly of a light violet-brown. These eggs are of a perfectly oval shape.

Mr. Charles D. Gibbes, of Stockton, writes that he found in a garden in that city a nest built by a pair of these birds that had become half domesticated. It was placed in a very thick arbor of honeysuckle. The body of the nest was composed of clippings from a hedge of osage orange, with thorns on them half an inch long. These twigs were tied and interlaced with twine and bits of cotton strings. Within this frame was a layer of fine weeds and grasses nicely arranged, the whole lined with horse-hair. The nest was found in May, and contained five eggs. The parents kept a good deal about the kitchen door, and would steal anything they had an opportunity to take. They made use of an old nest in the same garden as a receptacle for their stolen goods; among other things was found a large slice of bread-and-butter.

Cyanocitta californica, var. woodhousei, Baird
WOODHOUSE’S JAY

Cyanocitta woodhousei, Baird, Birds N. Am. 1858, 585, pl. lix.—Ib. Mex. B. II, Birds, 20, pl. xxi.—Cooper, Orn. Cal. 1, 1870, 304.

Sp. Char. Size and general appearance of C. californica. Bill slender. Graduation of tail one inch. Blue, with a very obscure ashy patch on the back. Sides of the head and neck and incomplete pectoral collar, blue; throat streaked with the same. Breast and belly uniform brownish-ash, glossed with blue; under tail-coverts bright blue. Sides of head, including lores, black, glossed with blue below; a streaked white superciliary line. Length, 11.50; wing, 5.35; tail, 6.10; tarsus, 1.60. Young. All the blue, except that of the wings and tail, replaced by dull ash.

Hab. Rocky Mountains and Middle Province of United States; north to Idaho and Wyoming (Ridgway); south to Northern Mexico; east to Wyoming and Colorado.

The bluish wash on the back nearly obscuring the dorsal patch, the general ashy tinge of the under parts, the decided blue under tail-coverts, and the longer and much slenderer bill, distinguish this form from californica, although probably both are geographical races of the same species.

Habits. This bird was first met with by Dr. Woodhouse among the San Francisco Mountains of New Mexico, and was given by him, in his Report of the Sitgreaves Expedition, as the California Jay. He states in regard to it, that wherever he found the piñon, or nut-pine (Pinus edulis), growing in New Mexico, this bird was sure to be there in great numbers, feeding upon the fruit of those trees. Among the men it was known as the piñon bird. Its notes are said to be harsh and disagreeable. It was extremely restless, and was continually in motion, flying from tree to tree, uttering its well-known cries.

Mr. Ridgway calls this a very interesting species, and states that it was found very abundant in the fertile cañons of the West Humboldt Mountains, as well as in all the extensive nut-pine and cedar woods to the eastward. On the Toyaba and East Humboldt Mountains, and the extensive piñon woods in Southern Idaho, it was equally common. In Utah, in the cañons of the Wahsatch Mountains, it was occasionally seen, though oftener observed in the valley of the Weber. When unmolested, this bird is, he states, very unsuspicious, and anything unusual at once excites its curiosity. Often when at work, in camp, skinning birds, on the edge of bushes, one of them would approach within a few feet, and quietly watch every movement. At Unionsville they were quite common in the gardens and around the door-yards of the town, and were very familiar and unsuspicious. Their cries greatly resembled those of the California Jay, and consisted of a repetition of harsh screeching notes.

This species, according to Dr. Coues, is a resident and a very abundant species in Arizona, where it is one of the most characteristic species. It was found in all situations, but seemed to shun dense pine woods, and to prefer to keep on the open hillsides, among the scrub-oaks, etc. In winter it collects in rather large flocks, sometimes as many as fifty together. They are, however, usually seen in small groups of six or seven individuals. They are said to be a restless, vigilant, shy, and noisy species.

Mr. C. E. Aiken found this bird a common and resident species in Colorado. He met with it along the foot of the mountains, in brush thickets, in which they also breed. The base and periphery of a nest found by him were composed of dead twigs, intermingled within with fine rootlets and horsehair. The eggs, four or five in number, are said to be laid about the first of May. They have a ground-color of a light bluish-green, and marked with reddish-brown specks, thickest at the larger end. They are of a rounded oval shape, much more pointed at one end, and rounded at the other, and average 1.06 inches in length by .80 of an inch in breadth.

3. Perisoreus canadensis. ♂ Nova Scotia, 26940.


4. Perisoreus canadensis. var. capitalis. ♂ Colorado, 51642.


Sp. Char. Bill short, thick; half as high as long. Wing considerably longer than the tail, which is slightly graduated (.50 of an inch). Upper surface (including whole side of head to the throat) light sky-blue, the whole dorsal region inclining to pure bluish-ashy. Beneath fine, uniform, pale ash for anterior half (including the throat), this gradually fading into white on the posterior portions (including whole abdomen), the lower tail-coverts being pure white. Lores blue. Length, 13.00; wing, 6.20; tail, 5.70; culmen, 1.30; depth of bill, .40; tarsus, 1.50; middle toe, .97. Fourth, fifth, and sixth quills equal and longest, second shorter than ninth; first 2.20 shorter than longest. (18,279, Fort Buchanan, Arizona, December; Dr. Irwin.) Immature (8,469 ♂, Copper Mines, Arizona). The blue, except that of the wings and tail, replaced by dull ash; the blue feathers appearing in scattered patches.

Hab. Arizona (Copper Mines, J. H. Clark; and Fort Buchanan, Dr. Irwin, U. S. A.).

The nearest ally of this race is the var. sordida of Mexico, which, however, differs in many important respects; the differences between the two being giving in the synopsis (page 880), it is unnecessary to repeat them here. In both there is a tendency towards a party-colored bill; each example of the northern style, and most of those of the southern, having more or less whitish on the lower mandible.

Nothing definite is known as to the habits or reproduction of this bird.

Cyanocitta ultramarina, var. couchi, Baird
ULTRAMARINE JAY

Garrulus ultramarinus, Bonap. J. A. N. Sc. IV, 1825, 386 (not of Audubon).—Temm. Pl. Col. II, 439. Cyanocitta ultramarina, Strickland, Ann. & Mag. XV, 1845, 260.—Gambel, J. A. N. Sc. 2d Ser.

Sp. Char. Tail rounded, but little graduated; lateral feather about a quarter of an inch shortest. Wings longer than the tail; when closed, reaching nearly to its middle. Above and on sides of head and neck bright blue; the lores blackish; the middle of the back slightly duller, the tips of some of the feathers dark brown. Beneath brownish-ash, paler on the chin and towards the anal region, which, with the crissum, is white. No trace of white or black on the sides of the head, nor of any streaks or collar on the breast. Length, (fresh,) 11.50; wing, 6.00; tail, (dried,) 5.40; tarsus, 1.50.

Hab. South side of valley of Rio Grande, near the coast, and southward.

This well-marked species is quite different in form from the C. californica, having a shorter, more even tail, much longer wings, and stouter feet. The absence of any collar or streaks on the breast and throat, of black or white on the side of the head, and of decided ash on the back, are very well marked features. There is also much more green in the blue of the head.

As suggested in the P. R. R. Report, the birds collected by Lieutenant Couch at Monterey, Mexico, although agreeing almost exactly with the original description of Bonaparte, are much smaller, and perhaps entitled to recognition as a separate form. The tail is nearly two inches less, 5.40 instead of 7.00, or over.

Habits. The Ultramarine Jay is a well-marked species, and is specifically quite distinct from the C. californica. It is found in the valley of the Rio Grande, and thence southward and eastward in the northern provinces of Mexico. Though we know of no specimens having been procured on this side of the boundary line, their occurrence is quite probable. Lieutenant Couch met with this species near Monterey, Mexico, and from thence west to Parras. He describes it as being gregarious and eminently Jay-like in its habits. They are very noisy and vociferous in their outcries, and three or four of them suffice to keep a whole forest in an uproar. Near Guyapuco a large snake (Georgia obsoleta) was seen pursued by three or four of this species. The reptile was making every effort to escape from their combined attacks, and would, no doubt, have been killed by them, had they not been interfered with. The cause of so much animosity against the snake was explained when, on opening its stomach, three young of this species, about two thirds grown, were found.

In the Department of Vera Cruz, Sumichrast found what he calls C. ultramarina in company with Cyanura coronata and Cyanocitta nana, “californica” (Sumichrasti), and sordida, occurring in the alpine region, and with the three first named restricted to that locality. The limit of their extension is about that of the alpine region, that is, from an elevation of about 4,500 feet to the height of 10,500 feet. The sordida is also found on the plateau.

Genus XANTHOURA, Bonap

Xanthoura, Bonaparte, Consp. Av. 1850. (Type, “Corvus peruvianus, Gm.”)

Char. Head without crest. Throat black. Lateral tail-feathers bright yellow. Bill very stout, rather higher than broad; culmen curved from the base. Nostrils rather small, oval, concealed by a nasal tuft varying in length with species. Tail longer than the wings; graduated. The wings concave, rounded; the secondaries nearly as long as the primaries. Legs very stout; hind claw about half the total length of the toe.


Xanthoura luxuosa.

4052


The genus Xanthoura is composed of three so-called species, of different geographical distribution, and exhibits a progressive change from one to the other, with variation of latitude that enforces assent to the hypothesis of their all belonging to one primitive form. These differences may be expressed as follows:—

Common Characters. Nasal tufts, patch on side of lower jaw and one above eye, (both eyelids,) bright blue; remainder of face and throat black. Back, and upper surface of wings and tail (the four central feathers), green, the latter tinged with blue at end; the rest of tail-feathers bright yellow. Belly and crissum varying from bright yellow to green. Forehead yellowish or whitish.

a. Nasal tufts short, only covering the nostrils; whole top of head (except anteriorly) and nape bright blue.

1. Body beneath, and crissum, green. Hab. Mexico and South Texas … var. luxuosa.

2. Body beneath, and crissum, yellow, sides more greenish. Hab. Guatemala and Honduras … var. guatemalensis.

b. Nasal tuft elongated, forming an anterior crest, the feathers reaching far beyond nostrils. Whole top of head pale heavy yellow, glossed behind with bluish.

3. Body beneath, and crissum, very bright gamboge-yellow. Hab. Colombia, Ecuador, Bogota, and Bolivia … var. incas.

Thus, starting with the green-bellied luxuosa of the Rio Grande, we come to the yellow-bellied guatemalensis; but intermediate localities show different proportions of the two colors. The nasal tufts in the first do not extend beyond the nasal fossæ; and the frontal yellowish is very narrow. In the second these tufts reach beyond the fossæ, and the frontal yellowish is more extended. In incas again the nasal tufts have reached their maximum, while the frontal yellowish extends over the whole cap, leaving only a trace of blue on the nape.
