Cassell's book of birds; vol. 4

by Alfred Edmund Brehm

As the Wild Swans, owing to their great size and strength, are well able to defend themselves against ordinary assailants, they have few enemies to fear, with the exception of the larger Eagles and of the arch-destroyer, man himself, who wages constant war against them, partly on account of their flesh, which affords excellent food, and partly for their feathers and down, the latter of which in particular is extremely valuable. The chase after these birds, however, requires considerable skill and perseverance, owing to their extreme watchfulness and the rapidity of their flight. In the north they are generally pursued in a boat whilst they are swimming in the water; the sportsman taking advantage of a high wind, and then steering with all sail directly towards them, in this manner he is sometimes able to approach them so closely as to get them within range of his gun, more especially as they always prefer to fly right against the wind. In Algeria, as Buvry informs us, they are taken in the same manner as the Flamingoes, by wading towards them under cover of floating herbage, or they are often captured on the shores of sheltered bays by means of hooks, and lines of camel's hair, baited with bread, flesh, or fish. When the bird has swallowed the bait, says Buvry, it must perforce remain quiet until the hunter comes to rescue it from its unpleasant position.

THE MUTE SWAN.

The MUTE SWAN (Cygnus olor), the species so frequently seen in this country living upon our ornamental water in a state of semi-domestication, and sometimes described by writers as the "Tame Swan" (Cygnus mansuetus) is, in its wild state, an inhabitant of Northern Europe and Northern Asia, more especially of Eastern Siberia, and is easily recognisable by the callous protuberance at the base of its bill. Its body is elongate, its neck extremely long and slender, and its bill, which is nearly of the same length as the head, of a red colour, surmounted at its base with the black knob-like protuberance above alluded to. The plumage of the adult is white, that of the young grey, or occasionally white. The eye is brown, the beak red, while the bridles and protuberance at the base[Pg 122] of the beak are black; the feet brownish or pure black. This bird is seventy inches long, and one hundred inches broad; the length of the wing is twenty-seven inches, and of the tail ten to eleven inches; the female is not quite so large. Brehm is of opinion that the Polish Swan (Cygnus immutabilis) of Yarrell, is merely a variety of the above species, but the following extract from a paper, read by Yarrell before the Zoological Society, will give our readers that naturalist's reasons for maintaining that these birds are not identical, although in their appearance, habits, and mode of life, they closely resemble each other. "The London dealers in birds," he says, "have long been in the habit of receiving from the Baltic a large Swan which they distinguish by the name of the Polish Swan. During the severe weather of January, 1838, several flocks of these Polish Swans were seen pursuing a southern course along the line of our north-east coast, from Scotland to the mouth of the Thames, and several specimens were obtained. The circumstance of these flocks being seen without any observable difference in the specimens obtained, all of which were distinct from our Mute Swan; the fact also that the Cygnets, as far as we observed, were of a pure white colour like the parent birds, and did not assume at any age the grey colour borne for the greater part of the first two years by the young of the other species of Swans; and an anatomical distinction in the form of the cranium, which was described by Mr. Pelerin in the Magazine of Natural History, induce me to consider this Swan as a distinct species, and in reference to the unchangeable colour of the plumage, I proposed for it the name of Cygnus immutabilis."

As additional peculiarities of this species, Yarrell notes that "the parent birds were remarkable in having the legs, toes, and their intervening membranes, of a pale ash-grey colour. The black tubercle at the base of the beak was of small size, and there was a slight difference in the nostrils, the elongated openings of which did not reach the black colour at the base of the beak." The Mute Swan, as it has erroneously been called from the fact of its possessing a soft voice very unlike the harsh tones of its wild brethren, utters a somewhat monotonous and plaintive call during the spring, or occasionally later in the season when moving about with its young. Col. Hawker, in his "Sporting Notes," describes this "Swan's melody" as consisting of two notes, C and the minor third E flat, adding that the musician he heard kept working with his head, as though delighted with the sounds he was producing. In England, where these birds live in a state of semi-domestication, they are met with at all seasons. During the period of incubation they live in pairs, and jealously drive away all intruders from the domain they have appropriated for the purpose of building. The nest, which is formed of a mass of reeds and rushes, is placed near the edge of the river or pond, or on an island, and by a most wonderful instinct is frequently raised to a height sufficient to escape a rising of the water even before man himself has observed any indication of such a danger. The eggs are six or seven in number, and have a dull greenish white shell; their length is about four inches by two inches nine lines broad. During the whole period of incubation, which lasts about six weeks, the male is in constant attendance to guard his spouse, boldly chasing off all intruders, and occasionally taking his place upon the nest. When first hatched, the young follow the mother about in the water, and are frequently carried on her back as she sails along the stream. Speaking of these birds in their wild state, Lloyd says, "In flying they make a strange appearance; their long necks protrude, and resemble at a distance long lines with black points; their heavy bodies and triangular wings seeming mere appendages to the prolonged neck. When thus in motion, their wings pass through so few degrees of a circle that, unless seen horizontally, they appear almost quiescent, their movements being widely different from the semicircular sweeps of the Goose. The Swan, when migrating, with a moderate wind in its favour, and mounted high in the air, travels at the rate of one hundred miles or more an hour. I have often timed the flight of the Goose, and found one mile a minute a common rapidity, and when the two birds, in a change of feeding ground, have been flying near each other, the Swan invariably passed with nearly[Pg 123] double the velocity." The Mute Swan was first brought to England from the island of Cyprus by Richard I., and is still regarded as a royal bird which no subject can claim when kept in a public river, except by permission of the crown. Formerly, when this permission was accorded, a Swan mark was granted in order to identify the property of the persons so endowed. In the days of Queen Elizabeth it was ordered that all Swans in the Thames and its tributaries should be "upped," i.e., taken up and marked on the skin of the bill on an appointed day in the presence of the king's Swanherd. This ceremony, known to us as "Swan hopping," was performed annually, until quite recently, upon the first Monday in August. The flesh of this Swan was formerly highly esteemed, and was served as one of the principal dishes on state occasions. The value of one of these birds in the reign of Edward III. may be estimated by the fact, that while the best Capon sold for sixpence, the best Hen for fourpence, and twelve eggs for one penny, the price of a Swan was fixed at four shillings, and the poulterers were forbidden by proclamation to exact a larger sum. The late Bishop of Norwich gave Mr. Yarrell the following account of the manner in which young Swans were formerly fed at Norwich for the table: "The town clerk," he says, "sent a note to the public Swanherd, and to the members of the Corporation there who had Swans and Swan rights. On the second Monday in August the Swans were collected in a small stew or pond (the number varying from fifty to seventy). They began to feed immediately, being provided with as much barley as they could eat, and were usually ready for killing in November; these were all Cygnets. If kept beyond November they begin to fall off, losing both flesh and fat, the flesh also becomes darker in colour and stronger in flavour." A printed copy of the following lines was usually sent with each bird:—

"TO ROAST A SWAN.

"Take three pounds of beef, beat fine in a mortar,

Put it into the Swan, that is when you've caught her;

Some pepper, salt, mace, some nutmeg, an onion,

Will heighten the flavour in Gourmand's opinion.

Then tie it up tight with a small piece of tape,
