A History of North American Birds, Land Birds. Volume 2

Mr. Dall states that these Blackbirds arrive at Nulato about May 20, where they are tolerably abundant and very tame. They breed later than some other birds, and had not begun to lay before he left, the last of May. Eggs were procured at Fort Yukon by Mr. Lockhart, and at Sitka by Mr. Bischoff.

Besides these localities, this bird was found breeding in the Barren Grounds of Anderson River in 69° north latitude, on the Arctic coast at Fort Kenai, by Mr. Bischoff, and at Fort Simpson, Fort Rae, and Peel River. It has been found breeding at Calais by Mr. Boardman, and at Halifax by Mr. W. G. Winton.

Eggs sent from Fort Yukon, near the mouth of the Porcupine River, by Mr. S. Jones, are of a rounded-oval shape, measuring 1.03 inches in length by .75 in breadth. In size, shape, ground-color, and color of their markings, they are hardly distinguishable from some eggs of Brewer’s Blackbird, though generally different. All I have seen from Fort Yukon have a ground-color of very light green, very thickly covered with blotches and finer dottings of a mixture of ferruginous and purplish-brown. In some the blotches are larger and fewer than in others, and in all these the purple shading predominates. One egg, more nearly spherical than the rest, measures .98 by .82. None have any waving lines, as in all other Blackbird’s eggs. Two from near Calais, Me., measure 1.02 by .75 of an inch, have a ground of light green, only sparingly blotched with shades of purplish-brown, varying from light to very dark hues, but with no traces of lines or marbling.

According to Mr. Boardman, these birds are found during the summer months about Calais, but they are not common. Only a few remain of those that come in large flocks in the early spring. They pass along about the last of April, the greater proportions only tarrying a short time; but in the fall they stay from five to eight weeks. They nest in the same places with the Redwing Blackbirds, and their nests are very much alike. In early summer they have a very pretty note, which is never heard in the fall.

Sp. Char. Bill stout, quiscaline, the commissure scarcely sinuated; shorter than the head and the hind toe; the height nearly half length of culmen. Wing nearly an inch longer than the tail; the second quill longest; the first about equal to the third. Tail rounded and moderately graduated; the lateral feathers about .35 of an inch shorter. General color of male black, with lustrous green reflections everywhere except on the head and neck, which are glossed with purplish-violet. Female much duller, of a light brownish anteriorly; a very faint superciliary stripe. Length about 10 inches; wing, 5.30; tail, 4.40.

Hab. High Central Plains to the Pacific; south to Mexico. Pembina, Minn.; S. Illinois (Wabash Co.; R. Ridgway); Matamoras and San Antonio, Texas (breeds; Dresser, Ibis, 1869, 493); Plateau of Mexico (very abundant, and resident; Sumichrast, M. B. S. I, 553).

Autumnal specimens do not exhibit the broad rusty edges of feathers seen in S. ferrugineus.

The females and immature males differ from the adult males in much the same points as S. ferrugineus, except that the “rusty” markings are less prominent and more grayish. The differences generally between the two species are very appreciable. Thus, in S. cyanocephalus, the bill, though of the same length, is much higher and broader at the base, as well as much less linear in its upper outline; the point, too, is less decurved. The size is every way larger. The purplish gloss, which in ferrugineus is found on most of the body except the wings and tail, is here confined to the head and neck, the rest of the body being of a richly lustrous and strongly marked green, more distinct than that on the wings and tail of ferrugineus. In one specimen only, from Santa Rosalia, Mexico, is there a trace of purple on some of the wing and tail feathers.

Habits. This species was first given as a bird of our fauna by Mr. Audubon, in the supplementary pages of the seventh volume of his Birds of America. He met with it on the prairies around Fort Union, at the junction of the Yellowstone and the Missouri Rivers, and in the extensive ravines in that neighborhood, in which were found a few dwarfish trees and tall rough weeds or grasses, along the margin of scanty rivulets. In these localities he met with small groups of seven or eight of these birds. They were in loose flocks, and moved in a silent manner, permitting an approach to within some fifteen or twenty paces, and uttering a call-note as his party stood watching their movements. Perceiving it to be a species new to him, he procured several specimens. He states that they did not evince the pertness so usual to birds of this family, but seemed rather as if dissatisfied with their abode. On the ground their gait was easy and brisk. He heard nothing from them of the nature of a song, only a single cluck, not unlike that of the Redwing, between which birds and the C. ferrugineus he was disposed to place this species.

Dr. Newberry found this Blackbird common both in California and in Oregon. He saw large flocks of them at Fort Vancouver, in the last of October. They were flying from field to field, and gathered into the large spruces about the fort, in the manner of other Blackbirds when on the point of migrating.

Mr. Allen found this Blackbird, though less an inhabitant of the marshes than the Yellow-headed, associating with them in destroying the farmers’ ripening corn, and only less destructive because less numerous. It appears to be an abundant species in all the settled portions of the western region, extending to the eastward as far as Wisconsin, and even to Southeastern Illinois, one specimen having been obtained in Wisconsin by Mr. Kumlien, and others in Wabash Co., Ill., by Mr. Ridgway.

In the summer, according to Mr. Ridgway, it retires to the cedar and piñon mountains to breed, at that time seldom visiting the river valley. In the winter it resorts in large flocks to the vicinity of corrals and barn-yards, where it becomes very tame and familiar. On the 3d of June he met with the breeding-ground of a colony of these birds, in a grove of cedars on the side of a cañon, in the mountains, near Pyramid Lake. Nearly every tree contained a nest, and several had two or three. Each nest was saddled on a horizontal branch, generally in a thick tuft of foliage, and well concealed. The majority of these nests contained young, and when these were disturbed the parents flew about the heads of the intruders, uttering a soft chuck. The maximum number of eggs or young was six, the usual number four or five. In notes and manners it seemed to be an exact counterpart of the C. ferrugineus.

Dr. Suckley found these birds quite abundant at Fort Dalles, but west of the Cascade Mountains they were quite rare. At Fort Dalles it is a winter resident, where, in the cold weather, it may frequently be found in flocks in the vicinity of barn-yards and stables. Dr. Cooper also obtained specimens of this Grakle at Vancouver, and regards it as a constant resident on the Columbia River. He saw none at Puget Sound. In their notes and habits he was not able to trace any difference from the Rusty Blackbird of the Atlantic States. In winter they kept about the stables in flocks of fifties or more, and on warm days flew about among the tree-tops, in company with the Redwings, singing a harsh but pleasant chorus for hours.

Dr. Cooper states it to be an abundant species everywhere throughout California, except in the dense forests, and resident throughout the year. They frequent pastures and follow cattle in the manner of the Molothrus. They associate with the other Blackbirds, and are fond of feeding and bathing along the edges of streams. They have not much song, but the noise made by a large flock, as they sit sunning themselves in early spring, is said to be quite pleasing. In this chorus the Redwings frequently assist. At Santa Cruz he found them more familiar than elsewhere. They frequented the yards about houses and stables, building in the trees of the gardens, and collecting daily, after their hunger was satisfied, on the roofs or on neighboring trees, to sing, for an hour or two, their songs of thanks. He has seen a pair of these birds pursue and drive away a large hawk threatening some tame pigeons.

This species has an extended distribution, having been met with by Mr. Kennicott as far north as Pembina, and being also abundant as far south as Northern Mexico. In the Boundary Survey specimens were procured at Eagle Pass and at Santa Rosalia, where Lieutenant Couch found them living about the ranches and the cattle-yards.

Mr. Dresser, on his arrival at Matamoras, in July, noticed these birds in the streets of that town, in company with the Long-tailed Grakles Q. macrurus and Molothrus pecoris. He was told by the Mexicans that they breed there, but it was too late to procure their eggs. In the winter vast flocks frequented the roads near by, as well as the streets of San Antonio and Eagle Pass. They were as tame as European Sparrows. Their note, when on the wing, was a low whistle. When congregated in trees, they kept up an incessant chattering.

Dr. Coues found them permanent residents of Arizona, and exceedingly abundant. It was the typical Blackbird of Fort Whipple, though few probably breed in the immediate vicinity. Towards the end of September they become very numerous, and remain so until May, after which few are observed till the fall. They congregate in immense flocks about the corrals, and are tame and familiar. Their note, he says, is a harsh, rasping squeak, varied by a melodious, ringing whistle. I am indebted to this observing ornithologist for the following sketch of their peculiar characteristics:—

“Brewer’s Blackbird is resident in Arizona, the most abundant bird of its family, and one of the most characteristic species of the Territory. It appears about Fort Whipple in flocks in September; the numbers are augmented during the following month, and there is little or no diminution until May, when the flocks disperse to breed.

“The nest is placed in the fork of a large bush or tree, sometimes at the height of twenty or thirty feet, and is a bulky structure, not distantly resembling a miniature Crow’s nest, but it is comparatively deeper and more compactly built. A great quantity of short, crooked twigs are brought together and interlaced to form the basement and outer wall, and with these is matted a variety of softer material, as weed-stalks, fibrous roots, and dried grasses. A little mud may be found mixed with the other material, but it is not plastered on in any quantity, and often seems to be merely what adhered to the roots or plant-stems that were used. The nest is finished inside with a quantity of hair. The eggs are altogether different from those of the Quiscali and Agelæi, and resemble those of the Yellow-headed and Rusty Grakles. They vary in number from four to six, and measure barely an inch in length by about three fourths as much in breadth. The ground-color is dull olivaceous-gray, sometimes a paler, clearer bluish or greenish gray, thickly spattered all over with small spots of brown, from very dark blackish-brown or chocolate to light umber. These markings, none of great size, are very irregular in outline, though probably never becoming line-tracery; and they vary indefinitely in number, being sometimes so crowded that the egg appears of an almost uniform brownish color.

“In this region the Blackbirds play the same part in nature’s economy that the Yellow-headed Troupial does in some other parts of the West, and the Cowbird and Purple Grakle in the East. Like others of their tribe they are very abundant where found at all, and eminently gregarious, except whilst breeding. Yet I never saw such innumerable multitudes together as the Redwinged Blackbird, or even its Californian congener, A. tricolor, shows in the fall, flocks of fifty or a hundred being oftenest seen. Unlike the Agelæi, they show no partiality for swampy places, being lovers of the woods and fields, and appearing perfectly at home in the clearings about man’s abode, where their sources of supply are made sure through his bounty or wastefulness. They are well adapted for terrestrial life by the size and strength of their feet, and spend much of their time on the ground, betaking themselves to the trees on alarm. On the ground they habitually run with nimble steps, when seeking food, only occasionally hopping leisurely, like a Sparrow, upon both feet at once. Their movements are generally quick, and their attitudes varied. They run with the head lowered and tail somewhat elevated and partly spread for a balance, but in walking slowly the head is held high, and oscillates with every step. The customary attitude when perching is with the body nearly erect, the tail hanging loosely down, and the bill pointing upward; but should their attention be attracted, this negligent posture is changed, the birds sit low and firmly, with elevated and wide-spread tail rapidly flirted, whilst the bright eye peers down through the foliage. When a flock comes down to the ground to search for food, they generally huddle closely together and pass pretty quickly along, each one striving to be first, and in their eagerness they continually fly up and re-alight a few paces ahead, so that the flock seems, as it were, to be rolling over and over. When disturbed at such times, they fly in a dense body to a neighboring tree, but then almost invariably scatter as they settle among the boughs. The alarm over, one, more adventurous, flies down again, two or three follow in his wake, and the rest come trooping after. In their behavior towards man, they exhibited a curious mixture of heedlessness and timidity; they would ramble about almost at our feet sometimes, yet the least unusual sound or movement sent them scurrying into the trees. They became tamest about the stables, where they would walk almost under the horses’ feet, like Cowbirds in a farm-yard.

“Their hunger satisfied, the Blackbirds would fly into the pine-trees and remain a long time motionless, though not at all quiet. They were at singing-school,’ we used to say, and certainly there was room for improvement in their chorus; but if their notes were not particularly harmonious, they were sprightly, varied, and on the whole rather agreeable, suggesting the joviality that Blackbirds always show when their stomachs are full, and the prospect of further supply is good. Their notes are rapid and emphatic, and, like the barking of coyotes, give an impression of many more performers than are really engaged. They have a smart chirp, like the clashing of pebbles, frequently repeated at intervals, varied with a long-drawn mellow whistle. Their ordinary note, continually uttered when they are searching for food, is intermediate between the guttural chuck of the Redwing and the metallic chink of the Reedbird.

“In the fall, when food is most abundant, they generally grow fat, and furnish excellent eating. They are tender, like other small birds, and do not have the rather unpleasant flavor that the Redwing gains by feeding too long upon the Zizania.

“These are sociable as well as gregarious birds, and allied species are seen associating with them. At Wilmington, Southern California, where I found them extremely abundant in November, they were flocking indiscriminately with the equally plentiful Agelaius tricolor.”

Dr. Heermann found this Blackbird very common in New Mexico and Texas, though he was probably in error in supposing that all leave there before the period of incubation. During the fall they frequent the cattle-yards, where they obtain abundance of food. They were very familiar, alighting on the house-tops, and apparently having no cause for fear of man. Unlike all other writers, he speaks of its song as a soft, clear whistle. When congregated in spring on the trees, they keep up a continual chattering for hours, as though revelling in an exuberance of spirits.

Under the common Spanish name of Pajaro prieto, Dr. Berlandier refers in MSS. to this species. It is said to inhabit the greater part of Mexico, and especially the Eastern States. It moves in flocks in company with the other Blackbirds. It is said to construct a well-made nest about the end of April, of blades of grass, lining it with horse-hair. The eggs, three or four in number, are much smaller than those of Quiscalus macrurus, obtuse at one end, and slightly pointed at the other. The ground-color is a pale gray, with a bluish tint, and although less streaked, bears a great resemblance to those of the larger Blackbird.

Dr. Cooper states that these birds nest in low trees, often several in one tree. He describes the nest as large, constructed externally of a rough frame of twigs, with a thick layer of mud, lined with fine rootlets and grasses. The eggs are laid from April 10 to May 20, are four or five in number, have a dull greenish-white ground, with numerous streaks and small blotches of dark brown. He gives their measurement at one inch by .72. They raise two and probably three broods in a season.

Four eggs of this species, from Monterey, collected by Dr. Canfield, have an average measurement of 1.02 inches by .74. Their ground-color is a pale white with a greenish tinge. They are marked with great irregularity, with blotches of a light brown, with fewer blotches of a much darker shade, and a few dots of the same. In one egg the spots are altogether of the lighter shade, and are so numerous and confluent as to conceal the ground-color. In the other they are more scattered, but the lines and marbling of irregularly shaped and narrow zigzag marking are absent in nearly all the eggs.

Mr. Lord found this species a rare bird in British Columbia. He saw a few on Vancouver Island in the yards where cattle were fed, and a small number frequented the mule-camp on the Sumas prairie. East of the Cascades he met none except at Colville, where a small flock had wintered in a settler’s cow-yard. They appeared to have a great liking for the presence of those animals, arising from their finding more food and insects there than elsewhere, walking between their legs, and even perching upon their backs.

Captain Blakiston found this species breeding on the forks of the Saskatchewan, June 3, 1858, where he obtained its eggs.

Genus QUISCALUS, Vieillot

Quiscalus, Vieillot, Analyse, 1816 (Gray). (Type, Gracula quiscala, L.)

Quiscalus purpureus.

2104

Sp. Char. Bill as long as the head, the culmen slightly curved, the gonys almost straight; the edges of the bill inflected and rounded; the commissure quite strongly sinuated. Outlines of tarsal scutellæ well defined on the sides; tail long, boat-shaped, or capable of folding so that the two sides can almost be brought together upward, the feathers conspicuously and decidedly graduated, their inner webs longer than the outer. Color black.

The excessive graduation of the long tail, with the perfectly black color, at once distinguishes this genus from any other in the United States. Two types may be distinguished: one Quiscalus, in which the females are much like the males, although a little smaller and perhaps with rather less lustre; the other, Megaquiscalus, much larger, with the tail more graduated, the females considerably smaller, and of a brown or rusty color. The Quiscali are all from North America or the West Indies (including Trinidad); none having been positively determined as South American. The Megaquiscali are Mexican and Gulf species entirely, while a third group, the Holoquiscali, is West Indian.

Sp. Char. Length about 12.50; wing, 5.50; tail, 4.92; culmen, 1.24; tarsus, 1.28. Second quill longest, hardly perceptibly (only .07 of an inch) longer than the first and third, which are equal; projection of primaries beyond secondaries, 1.56; graduation of tail, .92. General appearance glossy black; whole plumage, however, brightly glossed with reddish-violet, bronzed purple, steel-blue, and green; the head and neck with purple prevailing, this being in some individuals more bluish, in others more reddish; where most blue this is purest anteriorly, becoming more violet on the neck. On other portions of the body the blue and violet forming an iridescent zone on each feather, the blue first, the violet terminal; sometimes the head is similarly marked. On the abdomen the blue generally predominates, on the rump the violet; wings and tail black, with violet reflection, more bluish on the latter; the wing-coverts frequently tipped with steel-blue or violet. Bill, tarsi, and toes pure black; iris sulphur-yellow.

Hab. Atlantic States, north to Nova Scotia, west to the Alleghanies.

Var. purpureus.

This form is more liable to variation than any other, the arrangement of the metallic tints varying with the individual; there is never, however, an approach to the sharp definition and symmetrical pattern of coloration characteristic of the western race.

The female is a little less brilliant than the male, and slightly smaller. The young is entirely uniform slaty-brown, without gloss.

An extreme example of this race (22,526, Washington, D. C.?) is almost wholly of a continuous rich purple, interrupted only on the interscapulars, where, anteriorly, the purple is overlaid by bright green, the feathers with terminal transverse bars of bluish. On the lower parts are scattered areas of a more bluish tint. The purple is richest and of a reddish cast on the neck, passing gradually into a bluish tint toward the bill; on the rump and breast the purple has a somewhat bronzy appearance.

Habits. The common Crow Blackbird of the eastern United States exhibits three well-marked and permanently varying forms, which we present as races. Yet these variations are so well marked and so constant that they almost claim the right to be treated as specifically distinct. We shall consider them by themselves. They are the Purple Grakle, or common Crow Blackbird, Quiscalus purpureus; the Bronzed Grakle, Q. æneus; and the Florida Grakle, Q. aglæus.

The first of these, the well-known Crow Blackbird of the Atlantic States, so far as we are now informed, has an area extending from Northern Florida on the south to Maine, and from the Atlantic to the Alleghanies. Mr. Allen states that the second form is the typical form of New England, but my observations do not confirm his statement. Both the eastern and the western forms occur in Massachusetts, but the purpureus alone seems to be a summer resident, the æneus occurring only in transitu, and, so far as I am now aware, chiefly in the fall.
