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

The C. americanus has no analogue in Europe, though the C. corone somewhat resembles it. The most important feature of distinction appears to lie in the structure of the feathers of the head and neck, which in C. corone are narrow, with the tips distinct, while in the American bird these tips are blended together and do not maintain their individuality. The feathers on the fore-neck in corone are also lanceolate and distinct, showing the outline of each one as in the Raven, while in the American Crow they are three times as broad, rounded, and entirely blended. Mr. Audubon further remarks that the neck of the European bird is glossed with green and blue, while that of the American has a decided purplish-brown tinge.

Prince Maximilian states, in addition, that the note differs in the two species.

Habits. The Common Crow of North America is found in great abundance in all the Eastern States, from Texas to Florida, and from the Missouri to Nova Scotia. A few are found beyond the Great Plains, and they also extend their migrations, in summer, into high Arctic regions. Richardson found them as far north as the 55th parallel, but was in error when he stated that beyond this they do not go. He adds that none approach within five or six hundred miles of Hudson’s Bay. They were observed at Cross Lake and at Lake Winnepeg by Mr. Kennicott, at Big Island by Mr. Reid, at Fort Rae by Mr. Clarke, and at Fort Anderson and on the Lower Anderson River by Mr. MacFarlane, who also found them breeding even at this high latitude. They were not seen in Russian America, and Dr. Cooper thinks that the species does not occur in California, or, if at all, only rarely, but that it is there replaced by C. caurinus.

Mr. Ridgway found the Crow of very rare occurrence in the interior. A very few were seen in the Truckee meadows, in November, and others at the Humboldt marshes, in October. These western birds were exceedingly unsuspicious and familiar, so much so that those seen in the Humboldt marshes were walking about with all the familiarity of domestic pigeons, only hopping aside as they were approached. None were seen either in spring or summer.

In Western Iowa Mr. Allen states that he saw but very few of this species, and even in Northern Illinois it was not very common. At the West this bird is reported to be held in better estimation than at the East, by the farmers. It is not known to pull corn, and seems to be entirely unsuspicious. It is regarded generally as a benefactor, and not only deserves, but receives, good treatment. In Indiana he found it more common.

Dr. Coues met with a single individual on the Labrador coast. In Nova Scotia it is much more abundant, and there, as on the Western prairies, being unmolested by the inhabitants, it is exceedingly unsuspicious, and will permit a very near approach before it will fly, and even then will not move to a distance. In all of the United States east of the Mississippi it is very abundant. In Texas, between San Antonio and the Mexican frontier, it is not common; but Mr. Dresser found it very common in the northeast part of the State during the whole year.

Probably no one of our birds, so wholly worthless for food, has been more hunted and destroyed than this species. In certain parts of the country it is held in great aversion by the farmers, and in some States bounty-laws have been enacted by legislatures to promote its destruction. Had not these birds been possessed of an extraordinary intelligence, they must long since have been exterminated or driven from a large part of the country. In some sections their numbers have been of late much diminished by the use of strychnine. During the month of May the Crow is very destructive in the cornfield, pulling up the grains as soon as they begin to vegetate, and compelling the farmer to replant perhaps several times. Wilson remarks that in the State of Delaware these birds collect in immense flocks and commit great devastation upon crops of standing corn. They also occasionally commit depredations in the barn-yard, robbing hens’-nests of their eggs, and even destroying young chickens. They also destroy the eggs and young of other birds. The mischief they thus do is doubtless very great, and the ground for the prevalent prejudice against them is quite apparent. Yet it is equally demonstrable that this bird is surpassed, and probably is equalled, by no other in the vast amount of the benefits conferred upon agriculturalists. The evil it perpetrates is very limited, and is confined to but a short period, but during all the time it is resident the Crow is constantly engaged in the destruction of injurious insects and rodent quadrupeds. In the early spring it feeds almost wholly upon the most destructive grubs, and in extensive districts of Massachusetts, where these birds have been largely destroyed, the ravages of the May-bugs and the grasshoppers in pasture-lands have been a natural consequence of so short-sighted a policy.

The persecutions to which the Crow is subjected have developed in them a wariness and a distrust that is foreign to their nature. They can only live by keeping on a constant lookout for dangers, and by learning to distinguish the weapons that threaten their destruction. As soon as anything is seen that causes alarm, the signal is at once given, and the warning passed from one to another.

In New Jersey and in Pennsylvania, during the winter months, the Crows assemble in immense flocks, and their movements appear to be regulated by the guidance of a few chosen leaders. I received from the lips of the late John Cassin, an ornithologist hardly less remarkable for his outdoor observations than for his researches in the closet, only a few days before his death, a very surprising account of the movements of a large army of Crows, witnessed by himself, in the spring of 1868.

On a Sunday morning in April, when Philadelphia was enveloped in a fog so dense and impenetrable that it was hardly possible to distinguish objects across its streets, Mr. Cassin’s attention was called to an immense accumulation of these birds in Independence Square. The whole park he found, to his utter astonishment, occupied by an immense army of Crows. They filled all the trees, bending down the overloaded branches, and swarmed over and covered the ground. The entire space seemed alive with Crows. They had evidently become bewildered in the fog, and had strangely taken refuge in this small park in the very heart of Philadelphia. As if aware of their close proximity to danger, the whole assembly was quiet, orderly, and silent. A few birds, evidently acting as leaders, moved noiselessly back and forth through their ranks, as if giving tacit signals. These movements were followed by the departure of a few scouts, as if sent to make explorations, but they soon returned unsuccessful. Again were repeated the uneasy movements of their leaders, passing slowly and cautiously through their close ranks. After an apparently much longer consultation, another small party ascended to explore, wheeling round and round in wider and wider zones. At length, satisfied with their observations, they quietly returned, and made their report in a manner evidently understood, though not audibly expressed; for immediately the leaders passed again among the crowd, and, as if signals were given for a general movement, the whole of this immense congregation, numbering, Mr. Cassin estimated, hundreds of thousands, rose slowly and silently, preceded by their scouts, and, moving off in a westerly direction, were soon lost to view.

When taken young, the Crow can be easily domesticated, and becomes a very entertaining, but a very mischievous pet. It is very secretive, hiding objects of no value to itself, and seems to delight in mischief. It displays often a wonderful intelligence, appears to understand and to obey certain directions, and manifests also remarkable quickness of vision. A tame Crow belonging to a family resident near Boston, and permitted to go at large, manifested all the attachment of a dog. It especially enjoyed the society of the children, and played with them in their games of hide and seek, surpassing them by its readiness in finding the secreted object. It was especially attached to the mistress of the house, flying to her whenever she approached, hovering over her head, and alighting on her shoulder.

In a few instances the Crow has been taught to imitate articulate sounds. In one of these, in Grafton, Mass., the Crow not only vociferated a single monosyllable repeatedly, but at other times enunciated a short sentence of five syllables.

A few are resident in Massachusetts during the year, but the greater portion move south in November and return in March. Those who remain during the winter are chiefly resident near the sea-shore. The Crow breeds from April to June, varying with the latitude of its residence. In Massachusetts it has full-grown young by June 1. It builds, usually in March, a large rudely constructed nest of sticks, moss, and bark, lined with finer mosses, and sometimes with hair. The parent birds are very watchful and vigilant if their nest is in danger, and often expose their lives in their anxiety for their young. The male bird is attentive to his mate during incubation, and assists in feeding the young. The young are fed chiefly on insects, frogs, mice, and similar food.

The eggs of the Crow vary from 1.60 to 1.55 inches in length, and from 1.20 to 1.10 in breadth. In their markings they exhibit surprising variations. They usually have a ground of a light sea-green, over which are scattered, more or less thickly, blotches, some of them quite large, of a dark-brown, almost black, with purplish reflections. These are chiefly about the larger end. Another quite common variety is of a deeper ground of green, very uniformly and thickly sprinkled with fine dottings of a sepia-brown. Others have a ground nearly white, slightly tinged with green, more sparingly spotted with small blotches of light purplish-brown. A nest found near Springfield contained eggs having the ground-color on one side a pinkish-gray, the rest being greenish-white, all spotted with brown. Another set of eggs from Hudson, Mass., were of a light bluish-green, entirely unspotted, resembling large Robin’s eggs; and Dr. Wood mentions another four, the ground of which was flesh-color, and the spots red.

Corvus americanus, var. floridanus, BairdFLORIDA CROW

Corvus americanus, var. floridanus, Baird, Birds N. Am. 568, pl. lxvii, f. 1. C. americanus, Allen, B. E. Fla. 297.

Sp. Char. About the size of C. americanus, but bill and feet larger. Tail less rounded. Third, fourth, and fifth quills nearly equal; third rather longer than fifth. Color less violet above. Length, 19.50; wing, 12.00; tail, 7.70; tarsus, 2.60.

Hab. Southern peninsula of Florida.

This resident Crow of Florida differs in some marked features from that of the more northern localities in several characters. Although perhaps rather smaller, the bill and feet, especially the latter, are very considerably larger. The nasal feathers extend over the basal two fifths of the bill, instead of the half. The proportions of the bill are about the same; in the Florida bird it is rather the longer. The greatest difference is in the feet. The tarsal joint of the tibia is bare, the feathers scarcely coming below it, even anteriorly, instead of projecting some distance. The tarsus is almost a quarter of an inch longer, covered anteriorly by nine scutellæ, instead of eight. The outer lateral toe is shorter, not reaching the base of the middle claw. The middle toe and claw are considerably shorter than the tarsus; the middle claw is shorter than in the northern bird.

The wing-formula differs somewhat; the third, fourth, and fifth quills are nearly equal, the third even longer than the fifth, instead of shorter. The tail is short and very nearly even, the difference in length of feathers being less than half an inch, instead of an inch. This, however, may in part be owing to the absence of the middle pair.

The colors differ somewhat from those of the common Crow. There is less violet, and the feathers of the back have almost a brassy gloss on their margins, as in Crotophaga.

The specimen upon which these remarks are based, though apparently perfectly mature, is changing some of its feathers, such as the inner primaries, the middle tail-feathers, and the greater coverts. The long primaries and ten tail-feathers, however, are of full length. It is possible that the bird is really as large as the northern Crow, although this is hardly probable. It was killed on the mainland of the extreme southern portion of Florida, not far from Fort Dallas.

No comparison of this bird is required with the Fish Crow, which has the middle toe and claw longer than the tarsus, not shorter, and the proportions much less.

Habits. The common resident Crow of Florida exhibits so many peculiarities differing from the northern species, that Professor Baird, in his Birds of America, deemed it worthy of mention at least as a race, if not a distinct species. We have no account of its habits, and do not know if, in any respects, they differ from those of the common Crow. Dr. J. C. Cooper, in his brief manuscript notes on the birds of Florida, made in the spring of 1859, speaks of the Florida Crow as very common, as being quite maritime in its habits, and as having full-fledged young on the 20th of April. Three eggs of this race, obtained in Florida in the spring of 1871, by Mr. Maynard, differ not more from those of the Crow than do those of the latter occasionally from one another. They measure 1.73 by 1.20 inches; 1.70 by 1.20; and 1.54 by 1.25. Their ground-color is a bright bluish-green, and they are all more or less marked, over the entire egg, with blotches of a mingled bronze and brown with violet shadings. The latter tints are more marked in one egg than in the others, and in this the spots are fewer and more at one end, the larger end being nearly free from markings. Their average capacity, as compared with the average of the C. americanus, is as 5.1 to 4.2.

Corvus caurinus, BairdNORTHWESTERN FISH CROW

Corvus caurinus, Baird, Birds N. Am. 1858, 569, pl. xxiv.—Cooper & Suckley, 211, pl. xxiv.—Dall & Bannister, Trans. Chicago Acad. I, 1869, 286 (Alaska).—Finsch, Abh. Nat. III, 1872, 41 (Alaska).—Cooper, Orn. Cal. I, 1870, 285.

Sp. Char. Fourth quill longest; fifth and third about equal; second longer than sixth; first shorter than ninth. Color black, glossed with purple. Tail nearly even. Tarsus longer than middle toe and claw. Length about 16.50; wing about 11.00; tail about 7.00.

Hab. Northwestern coast, from Columbia River to Sitka.

This species is readily distinguished from the eastern Fish Crow by the larger size; the absence of green gloss on the belly; the tarsi longer than the middle toe and claw, instead of shorter; and the second quill being generally shorter than the sixth instead of longer, and considerably shorter than the culmen, instead of longer.

It is rather to be compared with C. americanus, with which it agrees in colors, but from which it differs, essentially, in having the wing and tail very much shorter, while the bill is considerably longer, and in having the tarsus shorter than the culmen, instead of longer, as in all the other North American species. In this last respect it agrees with C. mexicanus (see synopsis, p. 829) of Western Mexico; in this, however, the color and proportions are entirely different.

Habits. This species appears to be confined to the seaboard of the Pacific, from Alaska to California inclusive. Smaller than the common Crow, in its more essential features it closely resembles that bird, while in all its habits it appears the exact counterpart of the Fish Crow, from which it is specifically and essentially distinct.

It is found as far north as Sitka, several specimens having been procured at that point by Mr. Bischoff.

In the opinion of Dr. Suckley, the marked differences in the habits of this species from those of the common Crow, even more than the great difference in size, sufficiently mark them as entirely distinct. The western Fish Crow is never wary or suspicious, like the common species, but in its impudent familiarity with man resembles the English Jackdaw, and hardly learns to be shy even after having been annoyed with the gun. In Oregon and Washington Territory, he states, this Crow is very abundant, and is one of the marked ornithological features of the country. The great abundance of fish, especially of salmon, in both of these divisions, amply supplies this species with food. At Puget Sound it is abundant throughout the year. During the winter it subsists principally upon the refuse food and offal thrown out by the natives from their lodges. He describes it as cunning, but very tame and impudent, allowing a very near approach, and retiring but a short distance when pursued. Like the Raven and the Herring Gull, these birds are in the habit of carrying clams high into the air and then dropping them, in order to break the shell. Dr. Suckley observed one fruitlessly trying to break the shell of a clam by letting it drop on soft ground. In this effort he persisted perseveringly as long as he was watched.

Dr. Suckley found a nest of this species at Fort Dalles. It was situated in a dense willow-thicket, near a lagoon on the Columbia, and contained three eggs. He describes them as about an inch and a half long, and very wide in their short diameter, of a dirty green ground with brown spots.

Dr. Cooper speaks of it as much more gregarious and familiar than the common Crow, but otherwise resembling that bird in habits, being very sagacious, feeding upon almost everything animal and vegetable, differing rather in the tone than in the character of its cries. Its chief dependence for food being on the sea, it is generally found along the beach, devouring dead fish and other objects thrown up by the waves. At high tide the birds leave the shore and resort to dwellings near the sea, where they devour the offal and any refuse, vegetable or animal. As soon as the tide changes they are sure to notice it and to return to their favorite feeding-ground. They are very troublesome to the Indians, stealing their fish exposed for drying, and other articles of food. From some superstitious awe of them the Indians never molest these birds, but set their children to watch and drive them away. They build in trees near the shore, and the young are fledged in May.

In the southern half of California, Dr. Cooper states, these birds are rarely seen near the sea, preferring inland districts, and only occasionally coming to the shores of the bays to feed. During most of the year they associate in large flocks, feeding in company, and are gregarious even in the breeding-season, building in close proximity to one another. Frequently several nests may be found on the same tree. In this respect they are very unlike the eastern species, which never permit another pair near their nest.

These birds were found by Dr. Cooper breeding as far south as San Diego, where they selected for their breeding-places the groves of evergreen oaks growing in ravines. Their nests were from twelve to forty feet from the ground. In the north they generally build in spruces. He describes their nests as strongly built of sticks, coarse on the outside, but finer on the inside, where they are mingled with roots, grasses, moss, horse-hair, etc., to form a soft lining. The eggs, four in number, have a ground-color of a dark shade of green, thickly marked with dark brown and olive. He gives their average measurement as 1.60 by 1.10 inches. At San Diego they are laid about April 15.

Where unmolested, these birds have not yet become so shy as in the older districts, but they soon learn to apprehend the danger of a gun, and to evince the cunning characteristics of their tribe. They have not, as yet, manifested any disposition to disturb the growing crops, and the small depredations they commit are far more than counterbalanced by their destruction of immense numbers of grubs, grasshoppers, and other injurious insects. They obtain a large supply of food around the cattle-ranches.

In northern California they feed largely on fish, and on the Columbia on clams and oysters.

For reasons not well understood, they avoid particular districts during the breeding-season. Dr. Cooper has never noticed one, during this season, on the coast south of Santa Clara, has never seen one in the Colorado Valley, nor in the Sierra Nevada.

At Visalia, where an extensive forest of oaks forms an oasis in the great Tulare plain, he met with large flocks of these birds, with the same gregarious habits as were observed on the coast.

During the month of July, 1866, a large number of these Crows came every evening to roost in an alder-grove near the town of Santa Cruz. They gathered in long, continuous flocks from the neighboring fields, flying rather high. All at once they would descend, with zigzag turns, to the low trees, sportively chasing and pecking at one another, and chattering in the air.

Mr. John K. Lord, who enjoyed an unusually good opportunity of comparing the habits of our common Crow with those of this species, has not the slightest doubt as to their distinctness, though so very like in all essential respects, as far as color, form of bill, and other details are concerned. The smaller size of this bird, the difference in voice, and their habit of building with mud a domed nest, sufficiently demonstrate their difference. This Crow he found principally near the sea-coast; retiring to the trees at high tide, following out its ebb and retreating before its flood, they feed on any marine food they can find. The caw of this species reminded him of the Jackdaws of Europe. During the breeding-season they abandoned the coast, from early May resorting by pairs to the interior. Selecting patches of open prairie, they build their nests in the bushes of the crab-apple or wild thorn, and something in the manner of the Magpie, arching over the top with sticks, with two openings for entrance and exit on either side. The inside is plastered with mud, and lined with a few loose grass-stalks. The eggs he found generally small, and of a lighter color than those of the common Crow. After nesting, they return with their young to the sea-coast, and remain in large flocks. During the breeding-season they feed on small reptiles, freshwater mollusks, insects, grubs, etc. Mr. Lord noticed them capturing butterflies flying near their nests. Their eggs range in number from five to seven.

An egg of this species from Sitka measures 1.62 inches in length by 1.12 in breadth. It is of an oblong-oval shape, pointed at one end. The ground-color is a light sea-green, with marks and blotches of olive-brown, of varying size and different shades.

Sp. Char. Fourth quill longest; second rather longer than seventh; first shorter than the ninth. Glossy black, with green and violet reflections; the gloss of the belly greenish. Length, about 15.50; wing, 10.50; tail, less than 7.00; tarsus shorter than the middle toe and claw.

Hab. Atlantic coast, from New Jersey to Florida.

The Fish Crow of the Atlantic States is readily distinguishable from the common Crow by the much smaller size (16 inches instead of 20; wing, about 11 inches instead of 13); the bill is broader at the base and tapers more rapidly to the end; the middle toe and claw are longer than the scutellate portion of the tarsus, not shorter, the inner claw not reaching to the base of the middle one. The tail is less rounded. The gloss on the belly is green instead of violet; that on the back is mixed with green, not entirely violet.

Habits. The Fish Crow of Eastern North America has a distribution restricted to the Southern Atlantic and the Gulf shore. It is found in the States of New Jersey, Pennsylvania, Maryland, Delaware, Virginia, the Carolinas, Georgia, and Florida, and, according to Audubon, thence to the mouth of the Mississippi. West of that river it appears to be very rarely met with. Dr. Würdemann obtained it at Calcasieu, La. Mr. Allen, in a list of the birds of Massachusetts, published in 1864, names this species as an occasional visitor along the southern coast of that State, but I am not able to find any corroboration of the statement, and believe it to be a mistake. Dr. De Kay, in his Report on the birds of New York, states that this Crow is occasionally seen on the shores of Long Island, but Mr. Lawrence is confident that it never occurs farther north than Squaw Beach, in New Jersey. So, too, Mr. Townsend is quoted by both Audubon and Nuttall as authority for its occurrence on the Columbia River, of which we have no confirmation.
