Corvus americanus.
PLATE CLVI. Male.

The Crow is an extremely shy bird, having found familiarity with man no way to his advantage. He is also cunning—at least he is so called, because he takes care of himself and his brood. The state of anxiety, I may say of terror, in which he is constantly kept, would be enough to spoil the temper of any creature. Almost every person has an antipathy to him, and scarcely one of his race would be left in the land, did he not employ all his ingenuity, and take advantage of all his experience, in counteracting the evil machinations of his enemies. I think I see him perched on the highest branch of a tree, watching every object around. He observes a man on horseback travelling towards him; he marks his movements in silence. No gun does the rider carry,—no, that is clear; but perhaps he has pistols in the holsters of his saddle!—of that the Crow is not quite sure, as he cannot either see them or "smell powder." He beats the points of his wings, jerks his tail once or twice, bows his head, and merrily sounds the joy which he feels at the moment. Another man he spies walking across the field towards his stand, but he has only a stick. Yonder comes a boy shouldering a musket loaded with large shot for the express purpose of killing crows! The bird immediately sounds an alarm; he repeats his cries, increasing their vehemence the nearer his enemy advances. All the crows within half a mile round are seen flying off, each repeating the well known notes of the trusty watchman, who, just as the young gunner is about to take aim, betakes himself to flight. But alas, he chances unwittingly to pass over a sportsman, whose dexterity is greater; the mischievous prowler aims his piece, fires;—down towards the earth broken-winged, falls the luckless bird in an instant. "It is nothing but a crow," quoth the sportsman, who proceeds in search of game, and leaves the poor creature to die in the most excruciating agonies.

Wherever within the Union the laws encourage the destruction of this species, it is shot in great numbers for the sake of the premium offered for each crow's head. You will perhaps be surprised, reader, when I tell you that in one single State, in the course of a season, 40,000 were shot, besides the multitudes of young birds killed in their nests. Must I add to this slaughter other thousands destroyed by the base artifice of laying poisoned grain along the fields to tempt these poor birds? Yes, I will tell you of all this too. The natural feelings of every one who admires the bounty of Nature in providing abundantly for the subsistence of all her creatures, prompt me to do so. Like yourself, I admire all her wonderful works, and respect her wise intentions, even when her laws are far beyond our limited comprehension.

The Crow devours myriads of grubs every day of the year, that might lay waste the farmer's fields; it destroys quadrupeds innumerable, every one of which is an enemy to his poultry and his flocks. Why then should the farmer be so ungrateful, when he sees such services rendered to him by a providential friend, as to persecute that friend even to the death? Unless he plead ignorance, surely he ought to be found guilty at the bar of common sense. Were the soil of the United States, like that of some other countries, nearly exhausted by long continued cultivation, human selfishness in such a matter might be excused, and our people might look on our Crows, as other people look on theirs; but every individual in the land is aware of the superabundance of food that exists among us, and of which a portion may well be spared for the feathered beings, that tend to enhance our pleasures by the sweetness of their song, the innocence of their lives, or their curious habits. Did not every American open his door and his heart to the wearied traveller, and afford him food, comfort and rest, I would at once give up the argument; but when I know by experience the generosity of the people, I cannot but wish that they would reflect a little, and become more indulgent toward our poor, humble, harmless, and even most serviceable bird, the Crow.

The American Crow is common in all parts of the United States. It becomes gregarious immediately after the breeding season, when it forms flocks sometimes containing hundreds, or even thousands. Towards autumn, the individuals bred in the Eastern Districts almost all remove to the Southern States, where they spend the winter in vast numbers.

The voice of our Crow is very different from that of the European species which comes nearest to it in appearance, so much so indeed, that this circumstance, together with others relating to its organization, has induced me to distinguish it, as you see, by a peculiar name, that of Corvus Americanus. I hope you will think me excusable in this, should my ideas prove to be erroneous, when I tell you that the Magpie of Europe is assuredly the very same bird as that met with in the western wilds of the United States, although some ornithologists have maintained the contrary, and that I am not disposed to make differences in name where none exist in nature. I consider our Crow as rather less than the European one, and the form of its tongue does not resemble that of the latter bird; besides the Carrion Crow of that country seldom associates in numbers, but remains in pairs, excepting immediately after it has brought its young abroad, when the family remains undispersed for some weeks.

Wherever our Crow is abundant, the Raven is rarely found, and vice versa. From Kentucky to New Orleans, Ravens are extremely rare, whereas in that course you find one or more Crows at every half mile. On the contrary, far up the Missouri, as well as on the coast of Labrador, few Crows are to be seen, while Ravens are common. I found the former birds equally scarce in Newfoundland.

Omnivorous like the Raven, our Crow feeds on fruits, seeds, and vegetables of almost every kind; it is equally fond of snakes, frogs, lizards, and other small reptiles; it looks upon various species of worms, grubs and insects as dainties; and if hard pressed by hunger, it will alight upon and devour even putrid carrion. It is as fond of the eggs of other birds as is the Cuckoo, and, like the Titmouse, it will, during a paroxysm of anger, break in the skull of a weak or wounded bird. It delights in annoying its twilight enemies the Owls, the Opossum, and the Racoon, and will even follow by day a fox, a wolf, a panther, or in fact any other carnivorous beast, as if anxious that man should destroy them for their mutual benefit. It plunders the fields of their superabundance, and is blamed for so doing, but it is seldom praised when it chases the thieving Hawk from the poultry-yard.

The American Crow selects with uncommon care its breeding place. You may find its nest in the interior of our most dismal swamps, or on the sides of elevated and precipitous rocks, but almost always as much concealed from the eye of man as possible. They breed in almost every portion of the Union, from the Southern Cape of the Floridas to the extremities of Maine, and probably as far westward as the Pacific Ocean. The period of nestling varies from February to the beginning of June, according to the latitude of the place. Its scarcity on the coast of Labrador, furnishes one of the reasons that have induced me to believe it different from the Carrion Crow of Europe; for there I met with several species of birds common to both countries, which seldom enter the United States farther than the vicinity of our most eastern boundaries.

The nest, however, greatly resembles that of the European Crow, as much, in fact, as that of the American Magpie resembles the nest of the European. It is formed externally of dry sticks, interwoven with grasses, and is within thickly plastered with mud or clay, and lined with fibrous roots and feathers. The eggs are from four to six, of a pale greenish colour, spotted and clouded with a purplish-grey and brownish-green. In the Southern States they raise two broods in the season, but to the eastward seldom more than one. Both sexes incubate, and their parental care and mutual attachment are not surpassed by those of any other bird. Although the nests of this species often may be found near each other, their proximity is never such as occurs in the case of the Fish-Crow, of which many nests may be seen on the same tree.

When the nest of this species happens to be discovered, the faithful pair raise such a hue and cry that every Crow in the neighbourhood immediately comes to their assistance, passing in circles high over the intruder until he has retired, or following him, if he has robbed it, as far as their regard for the safety of their own will permit them. As soon as the young leave the nest, the family associates with others, and in this manner they remain in flocks till spring. Many crows' nests may be found within a few acres of the same wood, and in this particular their habits accord more with those of the Rooks of Europe (Corvus frugilegus), which, as you very well know, breed and spend their time in communities. The young of our Crow, like that of the latter species, are tolerable food when taken a few days before the period of their leaving the nest.

The flight of the American Crow is swift, protracted, and at times performed at a great elevation. They are now and then seen to sail among the Turkey Buzzards or Carrion Crows, in company with their relatives the Fish-Crows, none of the other birds, however, shewing the least antipathy towards them, although the Vultures manifest dislike whenever a White-headed Eagle comes among them.

In the latter part of autumn and in winter, in the Southern States, this Crow is particularly fond of frequenting burnt grounds. Even while the fire is raging in one part of the fields, the woods, or the prairies, where tall grass abounds, the Crows are seen in great numbers in the other, picking up and devouring the remains of mice and other small quadrupeds, as well as lizards, snakes, and insects, which have been partly destroyed by the flames. At the same season they retire in immense numbers to roost by the margins of ponds, lakes, and rivers, covered with a luxuriant growth of rank weeds or cat-tails. They may be seen proceeding to such places more than an hour before sunset, in long straggling lines, and in silence, and are joined by the Grakles, Starlings, and Reed Birds, while the Fish-Crows retire from the very same parts to the interior of the woods many miles distant from any shores.

No sooner has the horizon brightened at the approach of day, than the Crows sound a reveillÉ, and then with mellowed notes, as it were, engage in a general thanksgiving for the peaceful repose they have enjoyed. After this they emit their usual barking notes, as if consulting each other respecting the course they ought to follow. Then parties in succession fly off to pursue their avocations, and relieve the reeds from the weight that bent them down.

The Crow is extremely courageous in encountering any of its winged enemies. Several individuals may frequently be seen pursuing a Hawk or an Eagle with remarkable vigour, although I never saw or heard of one pouncing on any bird for the purpose of preying on it. They now and then teaze the Vultures, when those foul birds are alighted on trees, with their wings spread out, but they soon desist, for the Vultures pay no attention to them.

The most remarkable feat of the Crow, is the nicety with which it, like the Jay, pierces an egg with its bill, in order to carry it off, and eat it with security. In this manner I have seen it steal, one after another, all the eggs of a wild Turkey's nest. You will perceive, reader, that I endeavour to speak of the Crow with all due impartiality, not wishing by any means to conceal its faults, nor withholding my testimony to its merits, which are such as I can well assure the farmer, that were it not for its race, thousands of corn stalks would every year fall prostrate, in consequence of being cut over close to the ground by the destructive grubs which are called "cut-worms."

I never saw a pet Crow in the United States, and therefore cannot say with how much accuracy they may imitate the human voice, or, indeed, if they possess the power of imitating it at all, which I very much doubt, as in their natural state they never evince any talents for mimicry. I cannot say if it possess the thieving propensities attributed by authors to the European Crow.

Its gait, while on the ground, is elevated and graceful, its ordinary mode of progression being a sedate walk, although it occasionally hops when under excitement. It not unfrequently alights on the backs of cattle, to pick out the worms lurking in their skin, in the same manner as the Magpie, Fish-Crow, and Cow-bird. Its note or cry may be imitated by the syllables caw, caw, caw, being different from the cry of the European Carrion Crow, and resembling the distant bark of a small dog.

At Pittsburgh in Pennsylvania I saw a pair of Crows perfectly white, in the possession of Mr Lampdin, the owner of the museum there, who assured me that five which were found in the nest were of the same colour.

I have placed the pensive oppressed Crow of our country on a beautiful branch of the Black Walnut tree, loaded with nuts, on the lower twig of which I have represented the delicate nest of our Common Humming Bird, to fulfil the promise which I made when writing the history of that species for my first volume.

In conclusion, I would again address our farmers, and tell them that if they persist in killing Crows, the best season for doing so is when their corn begins to ripen.

Adult Male. Plate CLVI.

Bill longish, straight, robust, compressed; upper mandible with the dorsal line a little convex, declinate towards the end, the sides convex; lower mandible straight, the sides inclined obliquely outwards; the edges of both sharp and inflected. Nostrils basal, lateral, round, covered by bristly feathers, which are directed forwards. Head large, neck of ordinary length, body of moderate proportions, the whole form rather compact and not inelegant. Legs of moderate length, strong; tarsus anteriorly scutellate, rather longer than the middle toe; toes scutellate above, separated almost to the base; first, second, and fourth nearly equal in length, third longest; claws moderate, arched, compressed, acute.

Plumage of the back compact, of the head and neck blended, and glossy, of the lower parts rather loose. Stiff bristly feathers with disunited barbs over the nostrils, directed forwards and adpressed. Wings long, first primary short, fourth longest; primaries tapering, secondaries broad, the outer abrupt with a minute acumen, the inner rounded. Tail rather long, rounded, of twelve nearly straight, rounded feathers, their shafts distinctly undulated.

Beak, tarsi, toes and claws, black. Iris brown. The general colour of the plumage is deep black, with purplish-blue reflections, the hind parts of the neck tinged with purplish-brown; the lower parts less glossy.

Length 18 inches, extent of wings 3 feet 2 inches; bill along the ridge 2 2/12; tarsus 2½.

The Female differs from the Male in being less glossy, but the difference is not very perceptible. The young when fully fledged are of a rather dull brownish-black, with the blue and purple reflections much less brilliant.

After a careful comparison of specimens of the European Carrion Crow with others of the American Crow, I have found decided differences, which to me seem quite sufficient to set the question of their identity at rest.

The European Crow is larger than the American; the length of the former being 20 inches, that of the latter 18; and the wing from the flexure to the extremity is proportional, being in the one 13¼ inches, in the other 12.

The bill is stronger and deeper, more convex on the sides, and with the edges more involute in the Carrion Crow than in the American Crow, the depth at the base in the former being 10/12, in the latter 8½/12.

The scutella of the tarsus in both are 10, but the feet of the Carrion Crow are much stronger and its toes and claws larger than those of the other. In the European Crow, the fourth primary is longest, the third almost equal, and this is also the case in the American, although slight differences occur in individuals.

The principal character besides the different form of the bill, is to be found in the feathers of the neck. In the European bird, the feathers of the hind neck are narrow, and although blended, have their points distinct; while in the American bird, they are broad, rounded, and perfectly blended, so that their individual form cannot be traced. The feathers of the fore neck in the former are lanceolate, compact at the end, and, although shorter, resemble those of the Raven; but in the American Crow they are three times as broad, rounded, and entirely blended.

Lastly, the American species has a decided purplish-brown tinge on the neck, while the European bird has that part glossed with green and blue.

I am happy on this occasion to have an opportunity of referring you to an excellent paper, on the specific characters of birds, by Mr Macgillivray, which you will find in the Transactions of the Wernerian Natural History Society, and in which he shews the great advantage that may be derived from attending to the structure and form of the feathers. The characters by which the American Crow is distinguished from the European Carrion Crow are an exemplification of his views, in which I cordially agree:—"Allowing," says he, "only a partial application of the principle of characterizing the species by the forms of the feathers, even this would be a matter of importance; and were the attention of ornithologists directed toward this point, there can be little doubt that discoveries would quickly be made, which would determine species and varieties with much greater precision than can be attained by attending to colour alone."

THE BLACK WALNUT.

The Black Walnut of the United States is generally a tree of beautiful form, and often, especially in the Western and Southern States, attains a great size. Wherever it is found, you may calculate on the land being of good quality; the wood is very firm, of a dark brown tint, veined, and extremely useful for domestic purposes, many articles of furniture being made of it. It is also employed in ship-building. When used for posts or fence rails, it resists the action of the weather for many years. The nuts are gathered late in autumn, and although rather too oily, are eaten and considered good by many persons. The husking of them is however a disagreeable task, as their covering almost indelibly stains every object with which it comes in contact.
