THE JACKDAW CORVUS MONÉDULA

Crown of the head and upper parts black, with violet reflections; back of the head and nape grey; lower parts duller black; iris white; beak and feet black. Length thirteen inches; breadth twenty-seven inches. Eggs very light blue, with scattered spots of ash-colour and dark brown.

This lively and active bird, inferior in size as well as dignity to the Rook, yet in many respects resembles it so closely that it might be fabled to have made the Rook its model, and to have exercised its imitative powers in the effort to become the object of its admiration. A vain effort, however; for nature has given to it a slender form, a shriller voice, a partially grey mantle, and an instinct which compels it to be secretive even in the placing of its nest. Its note, which may be represented either by the syllable 'jack' or 'daw', according to the fancy of the human imitator, sounds like an impertinent attempt to burlesque the full 'caw' of the Rook; it affects to be admitted into the society of that bird on equal terms; but whether encouraged as a friend, or tolerated as a parasite whom it is less troublesome to treat with indifference than to chase away, is difficult to decide. Most probably the latter; for although It is common enough to see a party of Jackdaws dancing attendance on a flock of Rooks, accompanying them to their feeding-grounds, and nestling in hollow trunks of trees in close proximity to rookeries, they are neither courted nor persecuted; they come when they like and go away when they please. On the other hand, no one, I believe, ever saw a flock of Rooks making the first advances towards an intimacy with a flock of Jackdaws, or heard of their condescending to colonize a grove, because their grey-headed relatives were located in the neighbourhood. On the sea-coast, where Rooks are only casual visitors, the Jackdaw has no opportunity of hanging himself on as an appendage to a rookery, but even here he must be a client. With the choice of a long range of cliff before him, he avoids that which he might have all to himself, and selects a portion which, either because it is sheltered from storms, or inaccessible by climbers, has been already appropriated by Sea-mews.

The object of the Jackdaw in making church-towers its resort is pretty evident. Where there is a church there is at least also a village, and where men and domestic animals congregate, there the Jackdaw fails not to find food; grubs in the fields, fruit in the orchards, and garbage of all kinds in the waste ground. Here, too, it has a field for exercising its singular acquisitiveness. Wonderful is the variety of objects which it accumulates in its museum of a nest, which, professedly a complication of sticks, may comprise also a few dozen labels stolen from a Botanic Garden, an old tooth-brush, a child's cap, part of a worsted stocking, a frill, etc. Waterton, who strongly defends it from the charge of molesting either the eggs or young of pigeons, professes himself unable to account for its pertinacious habit of collecting sticks for a nest placed where no such support is seemingly necessary, and, cunning though it is, comments on its want of adroitness in introducing sticks into its hole: 'You may see the Jackdaw', he says, 'trying for a quarter of an hour to get a stick into the hole, while every attempt will be futile, because, the bird having laid hold of it by the middle, it is necessarily thrown at right angles with the body, and the Daw cannot perceive that the stick ought to be nearly parallel with its body before it can be conveyed into the hole. Fatigued at length with repeated efforts, and completely foiled in its numberless attempts to introduce the stick, it lets it fall to the ground, and immediately goes in quest of another, probably to experience another disappointment on its return. When time and chance have enabled it to place a quantity of sticks at the bottom of the hole, it then goes to seek for materials of a more pliant and a softer nature.' These are usually straw, wool, and feathers; but, as we have seen, nothing comes amiss that catches its fancy. In addition to rocks, towers, and hollow trees, it sometimes places its nest in chimneys or in rabbit-burrows, but never, or in the rarest instances, among the open boughs of a tree. It lays from four to six eggs, and feeds its young on worms and insects, which it brings home in the pouch formed by the loose skin at the base of its beak. When domesticated, its droll trickeries and capability of imitating the human voice and other sounds are well known. By turns affectionate, quarrelsome, impudent, confiding, it is always inquisitive, destructive, and given to purloining; so that however popular at first as a pet, it usually terminates its career by some unregretted accident, or is consigned to captivity in a wicker cage.

THE RAVEN CORVUS CÓRAX

Plumage black with purple reflections; tail rounded, black, extending two inches beyond the closed wings; beak strong, black as well as the feet; iris with two circles, the inner grey, the outer ash-brown. Length twenty-five inches; width four feet. Eggs dirty green, spotted and speckled with brown.

The Raven, the largest of the Corvidæ, and possessing in an eminent degree all the characteristics of its tribe except sociability, is the bird which beyond all others has been regarded with feelings of awe by the superstitious in all ages. In both instances in which specific mention of it occurs in Holy Writ, it is singled out from among other birds as gifted with a mysterious intelligence. Sent forth by Noah when the ark rested on the mountains of Ararat, it perhaps found a congenial home among the lonely crags strewed with the carcases of drowned animals, and by failing to return, announced to the patriarch that a portion of the earth, though not one fit for his immediate habitation, was uncovered by the waters. At a subsequent period, honoured with the mission of supplying the persecuted prophet with food, it was taught to suppress its voracious instinct by the God who gave it. The Raven figures prominently in most heathen mythologies, and is almost everywhere regarded with awe by the ignorant even at the present time. In Scandinavian mythology it was an important actor; and all readers of Shakespeare must be familiar with passages which prove it to have been regarded as a bird of dire omen.

In the Judgment of others, its friendly mission to the Tishbite invested it with a sanctity which preserved it from molestation.

Apart from all traditional belief, the Raven derives its ill-omened character as a herald of death from the rapidity with which it discerns, in the vicinity of its haunts, the carcase of any dead animal. In the coldest winter days, at Hudson's Bay, when every kind of effluvium is greatly checked if not arrested by frost, buffaloes and other beasts have been killed when not one of these birds was to be seen; but in a few hours scores of them have been found collected about the spot to pick up the blood and offal. 'In Ravens', says a writer in the Zoologist,'the senses of smell and sight are remarkably acute and powerful. Perched usually on some tall cliff that commands a wide survey, these faculties are in constant and rapid exercises, and all the movements of the bird are regulated in accordance with the information thus procured. The smell of death is so grateful to them that they utter a loud croak of satisfaction instantly on perceiving it. In passing any sheep, if a tainted smell is perceptible, they cry vehemently. From this propensity in the Raven to announce his satisfaction in the smell of death has probably arisen the common notion that he is aware of its approach among the human race, and foretells it by his croakings.' The same observant author, as quoted by Macgillivray, says again: 'Their sight and smell are very acute, for when they are searching the wastes for provision, they hover over them at a great height; and yet a sheep will not be dead many minutes before they will find it. Nay, if a morbid smell transpire from any in the flock, they will watch it for days till it die.'

To such repasts they are guided more by scent than by sight, for though they not unfrequently ascend to a great height in the air, they do not then appear to be on the look-out for food. This duty is performed more conveniently and with greater success by beating over the ground at a low elevation. In these expeditions they do not confine themselves to carrion, but prey indiscriminately on all animals which they are quick enough to capture and strong enough to master. Hares, rabbits, rats, mice, lizards, game of various kinds, eggs, and the larger insects, all of these enter into their diet, and, wanting these, they resort to the sea-shore for refuse fish, or ransack dunghills in villages, before the inhabitants are astir, for garbage of all sorts. Pliny even relates that in a certain district of Asia Minor they were trained to hawk for game like the noble Falcons. Few of these qualifications tend to endear them to mankind; and as they are dreaded by shepherds on account of their being perhaps more than suspected of making away with sickly lambs when occasion offers, and of plundering poultry yards, Ravens are become, in populous districts, almost unknown birds. I have only seen them myself on the rocky sea-shore of Devon and Cornwall, in the wilds of Dartmoor, and the Highlands of Scotland. There was for many successive years a nest built on a ledge of granite near the Bishop Rock, in Cornwall, a huge mass of sticks, and what appeared to be grass, inaccessible from below, but commanded by a venturous climber from above. Where it still continues to breed inland, it places its nest, constructed of sticks and lined with the wool and fur of its victims, either on an inaccessible rock, or near the summit of a lofty tree, the ill-omened 'Raven-tree' of romances. In the north of Scotland, in the Orkneys and Hebrides, where it is still abundant, it builds its nest in cliffs which it judges to be inaccessible, both inland and on the sea-shore, showing no marked preference for either. Two pairs never frequent the same locality, nor is any other bird of prey permitted to establish itself in their vicinity. Even the Eagle treats the Raven with respect, and leaves it to its solitude, not so much from fear of its prowess, as worn out by its pertinacious resistance of all dangerous intruders. Hence, in some districts, shepherds encourage Ravens, because they serve as a repellent to Eagles; while in others, where Eagles are of unusual occurrence, they allow them to build their nests undisturbed, but when the young are almost fledged, destroy them by throwing stones at them from above. Nevertheless the original pair continues to haunt the same locality for an indefinite term of years, and it is not a little singular that if one of them be killed, the survivor will find a mate in an incredibly short space of time.

The geographical range of the Raven is very extensive. Throughout all the zones of the Northern Hemisphere it is to be found; and having this wide range, its physical constitution is strong, and it lives to a great age, amounting, so the ancients tell us, to twenty-seven times the period of a man's life. The note of the Raven is well described by the word 'croak', but it is said by those who have had the opportunity of observing it under various circumstances, to utter another sound, resembling the word 'whii-ur'. With this cry it very commonly intermixes another, sounding like 'clung', uttered very much as by a human voice, only a little wilder in the sound. From the cry croak the Raven no doubt derives its Latin name Corvus the French Corbeau, and its common Scotch appellation Corbie.

THE CARRION CROW CORVUS CORÓNE

Black, with green and violet reflections; tail slightly rounded, extending an inch and a quarter beyond the closed wings; iris dark hazel; lower part of the beak covered with bristly feathers; beak and feet black. Length nineteen inches; breadth three feet. Eggs bluish green, spotted and speckled with ash-grey and olive.

Breeding early in the year, like the Raven, the Carrion Crow builds its nest in some tree which, from its loftiness or other reason, is difficult of ascent, where its young ones are hatched about the time that most other birds are laying their eggs, and when the lambing season is at its height. Then, too, its habits are most fully developed. Its young are clamorous for food, and will not be satisfied with a little. So the old bird sallies forth to scour the districts least frequented by man, and makes every living thing its prey, provided that by force or cunning it can overpower it. If Grouse are plentiful, it is said that one pair, what with stealing the eggs and carrying off the young, will in a season destroy more of them than the keenest sportsman. It will pounce on the leveret and bear it screaming from the side of its mother. It watches sheep which have strayed from the fold, and mangles the newly-born or weakly lambs, carrying them piece-meal to the young ones at home. If mowers are at work, the wary birds alight on some lofty tree, taking care to keep at a safe distance, and when a nest has been laid bare by the scythe, their incredibly sharp eye discerns the prize which, whether it consist of eggs or callow young, is borne off in triumph. Lest their depredations should be discovered by the accumulation of egg-shells, feathers and bones, which are the natural consequence of these raids, they carefully carry to some distance everything that would tend to betray them, so that one might pass directly beneath the scene of these enormities unsuspicious of the evil existing overhead. Keen as this bird is in pursuit of such delicate fare, he can be, when occasion serves, as unclean a feeder as the Vulture, and he can, on the other hand, make a meal off corn. Mr. Knox states that in the Weald of Sussex, where the Raven is common, it resorts to the brooks and ponds, which abound in fresh-water mussels (Anodon), and feeds on them most voraciously, especially after floods, when they lie scattered on the mud. The same author states that in winter it resorts to the sea-shore, and feeds on the oysters, mussels, small crabs, marine insects, worms, and dead fish which are cast up by the waves during the prevalent south-westerly storms. It has been frequently observed, he adds, to ascend to a great height in the air with an oyster in its claws, and after letting it fall on the beach, to descend rapidly with closed pinions and devour the contents. A similar instance of apparent reasoning is recorded of the same bird by Pliny, but with the substitution of walnuts for oysters.

With such wandering habits, it seems at first sight strange that the phrase 'as the Crow flies' should be adopted to mark distances in a straight line across the open country; yet when it is borne in mind how many persons confound the Crow with the Rook, and even talk of the 'Crows in a rookery', the suggestion will at once occur to the mind that the term owed its origin to its far gentler and more respectable relation, the Rook, whose evening flights from the feeding-ground are among the most familiar sights of the country, and are invariably performed in a line so straight, that if a whole flock could be tracked through the air on any one evening it would be found scarcely to deviate from that of the preceding or the following. It is to be feared that this inaccurate application of names has done the Rook ill service; yet the two birds are totally distinct; Crows are solitary birds, rarely being seen in more than pairs together; Rooks are eminently sociable. Crows shun the haunts of men; Rooks court the vicinity of his dwellings. Crows are carnivorous; Rooks feed principally on the grubs of beetles, worms, and noxious insects, rewarding themselves occasionally for their services by regaling on corn and fruits, but rarely touching carrion or molesting living animals. In appearance the two birds are much alike; the Crow, however, is somewhat smaller, the beak is stouter at the point and encircled at the base with numerous short feathers, while the bill of the Rook is encroached on by a white membrane which is almost bare of feathers. Both are noted for their intelligence; the Crow has been known to remove its eggs from its nest when apprehensive of danger; it was held in high consideration in the days of augury, and certain of its movements were considered to be indicative of changes in the weather. It builds its nest of sticks, and lines it with moss, straw, hair, and wool, and lays from four to six eggs. Like the Raven, it is a widely-diffused bird, and attains a great age, outliving (the ancients said) nine generations of men, showing great attachment to any spot in which it has once fixed its home, and suffering neither its own progeny nor any other large birds to nestle in its vicinity.

This Crow is becoming more numerous of late in the close vicinity of London. It comes constantly to some of our suburban gardens.

THE HOODED CROW, GREY OR ROYSTON CROW CORVUS CORNIX

Head, throat, wings and tail black, the rest of the plumage ash-grey; tail rounded; beak and feet black; iris brown. Length nineteen and a half inches; breadth three feet two inches. Eggs bluish green, mottled with ash-grey and olive.

The Hooded Crow closely resembles the Carrion Crow, scarcely differing from it in fact except in colour. They are, however, perfectly distinct species, and for the most part exercise their calling in separate haunts. In Norway Hooded Crows are very abundant, to the almost total exclusion of the Carrion Crow and Rook, and, though not congregating so as to form a society like the last-named bird, they may be seen simultaneously employed in searching for food in groups which collectively amount to a hundred or more. Though numerous in the winter at Newmarket Heath and Royston (where they are sometimes called Royston Crows), and annually resorting to many parts of the sea-coast, they rarely breed so far south. In the Isle of Man, the Orkneys, Hebrides, and in all but the south of Scotland they are of more frequent occurrence than any other of the tribe, essentially belonging to the 'Land of the mountain and the flood'. It is on the increase in Ireland and very unwelcome there. One can scarcely traverse the shores of the salt-water lochs of Scotland without seeing a pair, or, in the latter part of the year, a small party of four or five of these birds, gravely pacing the shingle and sand in quest of food. As far as my own experience goes, I should consider the Hooded Crow as 'half sea-bird', but it is said to be met with, in summer, in the very centre of the Grampians and other inland districts. Its proper diet consists of the smaller marine animals, such as crabs, echini, and molluscs, alive or dead, fish and carrion. At high-water it retires inland, and skulks about the low grounds in quest of the eggs and young of Moor-fowl, thereby gaining the execrations of gamekeepers; takes a survey of any adjacent sheep-walks, on the chance of falling in with a new-born lamb, or sickly ewe, whence it has but an ill name among shepherds; and returns when the tide has well ebbed, to finish the day's repast on food of a nature light and easy of digestion. It is less wary of man than the Carrion Crow, and often comes within shot, but, being far too numerous to admit of being exterminated, is but little assailed. In the comparatively mild climate of the Scottish sea-coast, these birds find an abundant supply of food all the year round and as there is no sensible diminution of their numbers in winter, it is supposed that those which frequent the English coast from October to March have been driven southwards by the inclement winters of high latitudes. They are then frequently observed on the coast of Norfolk and Sussex in parties of thirty or more, and it has been remarked that the hunting grounds of the two species are defined by singularly precise limits, the neighbourhood of Chichester being frequented by the Carrion Crow, that of Brighton by its congener. It is abundant on the sea-coast of Norfolk in the winter, where I have seen it feeding with Gulls, Plovers, etc. In musical capabilities it is inferior even to its relative, its solitary croak being neither so loud nor so clear. The nest of the Hooded Crow is large, composed of twigs, sea-weeds, heath, feathers, and straws, and is placed on rocks, tall trees, low bushes, and elsewhere, according to circumstances.
