Chapter VII: Preface (7)

On moorlands and cliffs by the sea-shore, the Merlin is tolerably abundant from Wales northwards, but in the south of England it is rarely seen. The nest is a mere "scrape" among the heather, or when near the sea-coast a former Crow's nest on a cliff is frequently appropriated, and it has been known to lay its eggs in old nests on trees. The eggs are very like those of the Hobby and Kestrel, from which they can with difficulty be distinguished.

The Merlin preys almost entirely on small birds; its flight is very swift and powerful and it is very bold, attacking birds as large as itself. Larks and Thrushes are its favourite prey, and on the sea-shore it is very fond of Dunlins and other kinds of Sandpipers.

Resident with us throughout the year, it nevertheless wanders about a good deal during the winter and becomes generally distributed, but the adults for the most part remain near their breeding haunts.

The adult male is slate grey on the back, throat white, under parts buffish, striped with dark brown. Length 11 in.; wing 7·8 in.

The female is browner above and with pale under parts. She is also rather larger than the male. The young resemble the female but they are more rufous in tint.

THE RED-FOOTED FALCON
Falco vespertinus, Linnæus

This species is commonest in Eastern Europe, and is gradually extending its range northwards; it migrates to Africa in winter. Some thirty examples have at long intervals occurred in this country, chiefly in the east and south.

The adult male has the head, throat, breast, and upper parts very dark lead grey; thighs and vent chestnut. The female has the head and nape chestnut; upper parts slate grey, with darker bars; under parts pale chestnut. Length 11·5 in.; wing 9·7 in.

KESTREL
Falco tinnunculus, Linnæus

The Kestrel, or as it is sometimes called, "the Windhover," is one of the most graceful and harmless of our small Hawks. Year in, year out, he is with us, and his beautiful flight may be observed throughout these islands. He may be seen on any fine day high up in the air, remaining apparently motionless, but ever and anon keeping his position by a few rapid and quivering wing-beats, he will then turn slowly sideways and, revealing as he does so a red back and dark quills, he will describe a wide curve and again hang motionless in the wind. He is at last beginning to be recognised as one of the farmer's most useful friends, and as a perfectly harmless adjunct to the Pheasant covert, and thus he is yearly becoming more abundant. He feeds entirely on mice and small rodents, and only occasionally on small birds such as Larks.

Towards the end of April the Kestrel repairs with his mate to his former abode or to some convenient spot near by. He does not build a nest for himself, but occupies the deserted home of a Crow or Magpie, a hole in a tree, if possible one which is open at the top, or the ledge of the cliff near the sea-shore. There, with little or no addition of material, the six eggs, of a beautiful rich red colour, are laid, but occasionally they have a paler ground colour and are blotched with deep red.

In about three weeks the young are hatched, and, as in the case of all birds of prey, are thickly covered with pale greyish down. At first their parents on bringing the food tear it up for them and allow the young to peck it from their beaks, but as they grow and their appetite increases (for their voracity at this age is enormous), the food is merely brought to the nest and the young tear it to pieces and eat it without further aid. Like several other birds, the Kestrel at such a time does not hunt in the immediate vicinity of his nest, and, except that he may occasionally be seen flying over, he is seldom "at home" to reveal the presence of his young. At the age of five or six weeks the young leave the nest; at first they do not fly much but remain perched near the nest and are still carefully watched and tended by the parents, while they gradually learn to catch and capture their own food.

At this time the family is always to be found near the nest, and that locality having been to a certain extent untouched, there is presumably abundant food for the young birds without their having to wander far afield. In this manner the summer passes, and as the days draw in and food becomes scarcer, the old birds become weary of their offspring and may frequently be seen fighting and driving them away. The young birds then take the hint, and leave the old folks at home, to wander forth all over the country and earn their living; many come down to the shore and emigrate, while others wander about till they find a suitable hunting ground in which to pass the winter.

With the advent of spring they have in their turn to seek a permanent home; perhaps they will meet with an older bird who has lost his mate during the winter and has a home ready, or perhaps they will inadvertently try to settle near an old eyrie and be driven away, but eventually a place will be found, and the inhabitants of a new district will be delighted, if they have eyes for Nature, by the charming ways and flight of their new visitors.

The adult male on the upper parts is of a deep chestnut, spotted or barred with black; under parts pale buff, striped with black. The head and nape are bluish grey, as is also the tail, which has a broad subterminal black band and is tipped with white. The female is more barred on the back and has the head brown, striped with darker. The tail is rufous, barred with black and slightly tinged with grey. The young resemble the female. Length 14 in.; wing 9·5 in.

THE LESSER KESTREL
Falco cenchris, Naumann

Very few examples of this small Hawk have been taken in this country. It is a summer visitor to Southern Europe, but towards the east it breeds in higher latitudes.

It may be distinguished from the Common Kestrel by its smaller size and white claws. Length 12·26 in.; wing 9·2 in.

THE OSPREY
Pandion haliaëtus (Linnæus)

This species may occasionally be seen on our shallow bays and estuaries or on inland lakes during the autumn migration, but its large size and conspicuous flight soon call forth a gunner and it is either shot or frightened away. It was never common in England, but in the eighteenth century it used to nest in a few localities. Nowadays only one or two eyries are known in the British Isles, and these are situated in remote parts of the Highlands of Scotland and zealously protected. Its food consists entirely of surface-swimming fish, on which it plunges from a considerable height.

The male has the head white, streaked with brown, rest of the upper parts brown; under parts white slightly spotted with brown on the breast. Legs greenish blue.

The female is rather larger and more spotted on the breast. The young have buff margins to the feathers of the back. Length 22 in.; wing 19 in.

THE CORMORANT
Phalacrocorax carbo (Linnæus)

With the Cormorant we come to quite another order of birds in which the feet, including the hind toe, are completely webbed. Their food consists entirely of fish, which they obtain by diving and of which they consume an immense quantity.

The Cormorant is abundant round all our shores and nests in colonies on rocky cliffs.

Its breeding places are very numerous and may be said to occur pretty generally wherever suitable localities are to be found. The nest is an untidy accumulation of seaweed, and the eggs, usually five in number, are pale blue in colour, but are thickly covered with a white chalky encrustation.

The young are blind at first and covered with blackish down. They feed on half-digested food, which they procure by inserting their head and neck into the parents' crop. It is rather a sedentary bird, spending much of its time on rocks just above high-water mark; in diving it moves almost entirely by means of its feet, the wings being kept closely folded to its side. When searching for food it places its head under water, and on sighting a fish dives under with scarcely a ripple; on being captured the victim is brought to the surface and swallowed head first, and the search for another is recommenced. Having satisfied his hunger he mounts a rock and stands there erect, drying himself in the wind with outstretched wings, for in spite of their diving habits the feathers of these birds have very little power of resisting water, and after a prolonged immersion become quite saturated. It flies well and strongly with the head and neck outstretched in front and looks not unlike a Duck. In some places it nests inland near large lakes, and in such localities the nest is placed on trees.

The adult is of a deep glossy greenish black, which becomes more bronze in tint on the mantle. Many of the feathers on the head and neck are white, and there is a white patch on the thighs which is assumed during the winter and lost in May. The young are brownish and lack the gloss of the old birds; the under parts are whitish. They become adult in about three years. Length 36 in.; wing 14 in.

THE SHAG
Phalacrocorax graculus, Linnæus

The Shag is widely distributed round our coasts, especially those rocky portions abounding in caves, on the ledges of which it breeds. It is a smaller and more local species than the last, and is never found breeding inland and rarely in colonies. In all other ways it is a counterpart of its larger congener, with which it is often confounded by local fishermen.

During the breeding season it is rather noisy, the note being a harsh "kraik, kraik."

The adult is of a uniform glossy bronze green and wears for a short time in spring an upright and forwardly-directed crest. The young resemble those of the Cormorant except in size, but the tail has only twelve, instead of fourteen tail feathers, and this forms an unmistakable character at all ages. The absence of the pale gular pouch will also enable this species to be recognised when on the wing. Length 27 in.; wing 10·75 in.

THE GANNET
Sula bassana (Linnæus)

The Gannet is a local species, nesting in enormous numbers on certain rocks which have formed their home for centuries. These colonies are pretty well distributed round our coasts, especially in Scotland and Ireland, but in England, the Farn Islands on the east, and Grassholm in Wales, are their only strongholds, a former colony on Lundy Island being nearly, if not quite, exterminated. The Bass Rock, one of the largest and best known of these colonies, is, in summer, a sight never to be forgotten; the whole of the face of the cliff appearing entirely white, from the closely packed sitting birds, who at this season are very tame and allow themselves to be stroked while incubating.

The nest is a loose accumulation of seaweed and other materials picked up along the shore. A single egg only is laid, which, except in size, resembles that of the Cormorant. The young when first hatched are black and naked, but soon assume a thick covering of white down; they remain in the nest a long time, not leaving it until they are fully fledged.

A party of Gannets fishing is a beautiful sight; they are not divers like the Cormorant but feed on surface-swimming fish, and in winter often follow the shoals of herring and mackerel. Having marked his fish from high up in the air, the Gannet folds his wings and drops on it perpendicularly, striking the water with great force. When not at its breeding haunts it keeps more out at sea than its rock-loving congeners and is very seldom seen sitting on the shore.

The adult is pure creamy white, buff on the crown and nape, and with black primaries. In their first year the young are brown all over, each feather having a small triangular white spot at the tip. The adult plumage is not assumed until the fifth or sixth year, the plumage during youth being various intermediate stages. Length 34 in.; wing 19 in.

THE COMMON HERON
Ardea cinerea, Linnæus

Owing to its shy, retiring, and wary habits, this bird is still fairly common with us. It spends the late summer and winter in marshes by the sides of sluggish rivers and ditches, patiently waiting for some unwary fish to come within striking distance of its formidable bill. Frogs, snakes, rats, and mice are also equally relished, and it is by no means dainty or particular as to its food.

In former days it was strictly protected and used as quarry for hawking, in which chase the Hawk would often receive serious wounds from the deadly dagger-shaped beak.

The Heron nests in colonies on high trees, the nest being built of sticks, lined with small twigs, moss, and wool. Five eggs of a uniform greenish blue form the clutch, and the young, which are extremely helpless when first hatched, are carefully fed by their parents on predigested food. The flight of this species appears slow and lumbering. The legs are carried stretched out behind and the head and neck closely folded in to the body. When disturbed or alarmed they utter a harsh "frank, frank." Although usually nesting inland, they may often be found by the sea-shore in autumn and winter, especially during hard weather when their inland haunts are frozen over.

The adult is bluish grey on the upper parts; the head and neck are white with the exception of the crest, which is bluish black, as well as a row of dark longitudinal markings on either side of the neck. Under parts greyish white. Shoulders bluish black. The young resemble their parents but are browner and lack the long filamentous plumes on the back and base of the neck. The adult plumage is assumed by degrees, not reaching its full beauty till in the fourth or fifth year. Length 34 in.; wing 19 in.

THE PURPLE HERON
Ardea purpurea, Linnæus

The Purple Heron inhabits marshes in South and Central Europe, building a nest low down in the reeds, its nearest nesting place to us being in Holland. A good many examples, mostly immature, have occurred along our east coasts. On the back the adult is dark slate grey with rufous and buff dorsal plumes. Neck reddish, with dark elongated stripe down either side. Under parts rich maroon red. Immature birds are rusty red on the neck and upper parts, brownish on the under parts. Length 33 in.; wing 14·25 in.

THE GREAT WHITE HERON
Ardea alba, Linnæus

Very few examples of this large species have occurred in Great Britain. It breeds on the Danube and thence eastwards in South Russia. The plumage is pure white, legs and feet black. This species has become much scarcer owing to persecution for its plumes, known as "ospreys." Length 33 in.; wing 17 in.

THE LITTLE EGRET
Ardea garzetta, Linnæus

This species breeds in Europe in the countries bordering the Mediterranean. It has only occurred in these islands on two or three occasions. Plumage pure white. Length 21 in,; wing 11·25 in.

THE BUFF-BACKED HERON
Ardea bubulcus, Audouin

A scarce species in Southern Europe, but breeding in the marismas of Spain. It is often found perched on the backs of cattle. Only known in England from one example shot in 1805. Plumage white, except the crown, nape, and back, which are saffron yellow. Length 20 in.; wing 9·5 in.

THE SQUACCO HERON
Ardea ralloides, Scopoli

The Squacco Heron breeds in suitable localities throughout Central and Southern Europe, and has visited this country on a good many occasions, generally during the spring immigration. Head, neck, and back pale buff, the crown and nape streaked with dark lines. Sides and front of the neck buff; under parts white. Length 20 in.; wing 9 in.

THE NIGHT HERON
Nycticorax griseus (Linnæus)

This species has frequently occurred on our south and east coasts at irregular intervals, and on one occasion eight adult birds were destroyed during the breeding season, when they might possibly have nested. It breeds chiefly in Southern and South-eastern Europe, but a few pairs still nest in Holland and Northern Germany.

The crown, nape, and back of the adult are greenish black; the neck, tail, and wing coverts drab; the under parts greyish white. Length 23 in.; wing 12 in.

THE LITTLE BITTERN
Ardetta minuta (Linnæus)

This species is abundant in summer throughout Central and Southern Europe, migrating to Africa for the winter months. To Northern Europe it is only a scarce straggler, but in the United Kingdom it has been obtained fairly frequently, especially in our eastern and southern counties, and there is little doubt that it has on more than one occasion stayed to breed. It inhabits thick reed-beds, and when disturbed either creeps away with great speed through the vegetation or remains motionless with head erect, in which position it closely resembles the reeds.

The male has the crown, nape, back, quills, and tail greenish black, the rest of the plumage buff, paler on the wing coverts. The female has the crown, nape, and back brown, and the under parts buff, streaked with brown. The young resemble the female. Length 13 in.; wing 6 in.

THE COMMON BITTERN
Botaurus stellaris (Linnæus)

Owing to drainage and cultivation, the Bittern, which used formerly to breed in various swamps and reed-beds, especially in our eastern counties, is now only known as a migrant. It still occurs yearly on our shores, and if unmolested it is probable that it would once more nest with us.

The nest is a heap of reeds placed on the marsh in the thickest part of a reed-bed. The eggs are usually four in number and of a uniform brownish olive colour. In the breeding season it utters a loud "booming" noise, but at other times it is a very silent bird.

The adult is buff, irregularly barred and streaked all over with black, except on the head, which is pure black. Sexes and young are alike in plumage. Length 28 in.; wing 13 in.

THE AMERICAN BITTERN
Botaurus lentiginosus (Montagu)

This bird was, curiously enough, first described from a specimen killed in Dorset. It is a purely American species but a good many examples have been taken in all parts of the United Kingdom. It may be distinguished from the preceding species by its smaller size, darker coloration, and uniformly brown primaries. Length 24 in.; wing 11 in.

THE WHITE STORK
Ciconia alba, Bechstein

It is curious that a bird so common and well protected on the Continent should not be of more general occurrence in these islands. It can only be considered a rare straggler, most of the examples having been seen in spring.

The whole plumage is white, except the quills, which are black. Legs and bill crimson. Length 40 in.; wing 23 in.

THE BLACK STORK
Ciconia nigra (Linnæus)

Some fourteen examples in all of this fine bird have been procured in England. It breeds in Sweden, Denmark and East Germany and thence eastwards in Central and Southern Russia. Like the White Stork, it is a migrant, wintering in Africa.

The whole of the plumage is black, with metallic reflections, except the lower breast and vent, which are white. Length 38 in.; wing 21 in.

THE GLOSSY IBIS
Plegadis falcinellus (Linnæus)

In the southern and eastern parts of England this species used to be well known as an autumn migrant, but of late years it has become decidedly scarcer. It breeds commonly in the marismas of Spain and the marshes of the Danube.

The head, neck, and under parts are a deep coppery brown; back, wings, and tail glossy brownish black. The bill is long and shaped like that of a Curlew. The sexes and young are alike in plumage. Length 22 in.; wing 10·75 in.

THE SPOONBILL
Platalea leucorodia, Linnæus

This species used formerly to breed in several localities in England, but these have long been deserted. It, however, still occurs on migration, and a few annually visit the Norfolk Broads in spring, where, as they are now strictly protected, it is to be hoped that they may once again be induced to nest. It still nests in Holland, but in other districts where it used to occur it seems to have died out as a breeding species, and is now restricted to more southern localities, such as the south of Spain, the Danube, and the Black Sea.

The whole of the plumage is white; gular pouch orange; bill black, with yellow tip; legs black. The sexes are alike in plumage. The young may be distinguished by the black ends to the quill feathers and the flesh-coloured bill. The adult plumage is not fully assumed till in the second or third year. Length 36 in.; bill 8·5 in.; wing 14·5 in.

THE FLAMINGO
Phoenicopterus roseus, Pallas

This curious and well-known bird is only a very rare straggler to our shores. It breeds in the Camargue district at the mouth of the Rhone as well as in Spain, but its main breeding grounds are in Africa. It nests in colonies, the nests being conical structures, formed of mud, built near the edge of the water. It is now definitely ascertained that it sits with its long legs doubled up, and not straddle-legged as was stated by early travellers. The food consists of minute crustacea and other insects.

The adult is of a pale rose pink all over, darker on the wing coverts. The quills are black. Legs pink; bill rosy, with black tip. The young are of a pale mottled brown. Length about 5 ft.; wing 15 in.

THE GREY LAG GOOSE
Anser cinereus, Meyer

Although about a century ago this bird used to nest in the fens of Cambridge and Lincolnshire, it has long since ceased to do so, and the only places where it may still be found breeding in these islands are in the north of Scotland and in the Outer Hebrides. In winter it occurs on our coasts in company with other species of Geese, but it is by no means common, and the majority pass on to the south, reappearing on their way north in spring. The food consists chiefly of grass and other green food, which it seeks on salt marshes near the sea by day, retiring to the shore to rest at night. It is the only Goose that breeds in our islands. The nest is begun in the middle of April and consists merely of a "scrape" amongst the grass or heather which is lined, as incubation proceeds, with down plucked from the body of the female. The eggs are usually six in number and dull yellowish white in colour.

As soon as the female begins to sit the males gather together in small flocks and take no further interest in their mates. Geese are strong fliers, and, being very wary birds, extremely difficult to approach. In flight they usually assume a wedge-shaped formation known as a "skein." The note is a harsh "gaggle, gaggle," like that of our domestic Goose, which is supposed to have originated from this species.

There is some doubt as to the origin of the name Grey Lag, but it is now generally conceded to have been applied to this species because it lagged behind after the other Geese had gone to their breeding quarters in the north.

The adult is greyish brown on the upper parts and breast, the rest of the under parts being whitish grey with a few black feathers. The young are rather darker and lack the black feathers underneath. Length 34 in.; wing 17 in.

THE WHITE-FRONTED GOOSE
Anser albifrons (Scopoli)

This Goose, whose chief breeding grounds are in Siberia, though it also nests across the whole of Northern Europe, visits us in fair numbers every winter, but it is more abundant in the south and south-west than on the east coast, and is everywhere very local in its distribution.

It very closely resembles the Grey Lag Goose, but there is more white on the forehead; the bill is orange yellow with white nail, and the legs orange. Length 27 in.; wing 16 in.

THE BEAN GOOSE
Anser segetum (J. F. Gmelin)

This species nests throughout Northern Europe and Asia. It is common on our coasts in winter, and is in fact the most abundant of our wild Geese. In Scotland, however, it is not so numerous as the preceding species.

This bird feeds inland on grain and vegetation.

The bill is black, with an orange band across the centre and a _black_ nail; the amount of orange on the bill varies, however, in individuals, and several forms have been differentiated, though the matter requires further confirmation before being finally accepted. The amount of orange in the bill may also vary, in some cases, during the life of a single individual. Legs orange yellow. There is no bluish grey on the shoulder of the wing, as in the Grey Lag and Pink-footed. Length 34 in.; wing 19 in.

THE PINK-FOOTED GOOSE
Anser brachyrhynchus, Baillon

On the east of England and Scotland this species is very plentiful during the winter, but in the south of England and on our west coasts it is comparatively rare, and its occurrence in Ireland is not yet authenticated. It breeds in Northern Europe and is apparently the only "Grey Goose" breeding on Spitzbergen.

The bill is black, with pink across the centre and a black nail. Legs pink. This pink colour has sometimes a yellowish tinge and so cannot be accepted as a definite character on which to diagnose this species. The wing, however, in the Pink-footed Goose is blue grey, approaching that of the Grey Lag, and this, together with its smaller size, will distinguish it from the preceding species. Length 28 in.; wing 17·5 in.

THE SNOW GOOSE
Chen hyperboreus (Pallas)

This is a North American species, breeding in Arctic Regions and wandering south in winter. It has occurred several times in Ireland, and small flocks were seen in Cumberland, Northumberland, and Yorkshire during the severe winter of 1890-91.

The adult is pure white, with black quills. The young is brownish grey on the back, lighter on the under parts. Length about 30 in.; wing 17 in.

THE RED-BREASTED GOOSE
Bernicla ruficollis (Pallas)

Only one or two examples of this rare Goose have been obtained in this country. It breeds in Eastern Siberia, whence it migrates southwards past the Ural and Caspian Seas.

The general colour above is black; the ear patches, throat, and breast chestnut; lores and belly white; chin black. Length 21 in.; wing 14·5 in.

THE BERNACLE GOOSE
Bernicla leucopsis (Bechstein)

Nesting abundantly in Greenland and in some numbers on Spitzbergen, the Bernacle Goose is by no means uncommon in winter along the west coast of the United Kingdom as far south as Lancaster, as well as on the north coast of Ireland. Elsewhere in these islands it is decidedly rare. It feeds on grass pastures near the sea, almost invariably by night.

This species is commonly kept in captivity, where it breeds freely.

The crown of the head, neck, and upper breast are black; mantle grey, barred with black and white; forehead, cheeks, and chin white. Under parts greyish. Tail coverts pure white. Length 27 in.; wing 16 in.

THE BRENT GOOSE
Bernicla brenta (Pallas)

This species is one of the most abundant of our Geese, and is found in enormous flocks round our coasts throughout the whole winter. It breeds along the west coast of Greenland and also on the islands and northern coasts of Russia and Siberia. It feeds chiefly by day, and is fond of wading about in mud-flats or in shallow water feeding on aquatic vegetation.

The whole plumage is chiefly black, except the tail coverts, which are white, and a white patch on each side of the neck. Length 22 in.; wing 13 in.

THE WHOOPER SWAN
Cygnus musicus, Bechstein

Formerly breeding in small numbers in the Orkneys, this species now only visits us during the winter, its numbers depending largely on the severity of the climate in Northern Europe. It frequents bays, estuaries, and inland lakes, feeding on weeds and aquatic vegetation. The note is a loud "whoop, whoop, whoop," from which its trivial name has been derived, and is often uttered as they fly along the shore in a long straggling line. The sexes are alike in plumage, as are all palæarctic Swans, and this species may be distinguished by the colour of the bill, which is black at the tip and yellow at the base, the yellow extending forward beyond the openings of the black nostrils. The base of the bill is flat and quadrangular and not knobbed as in the Mute Swan. Length 60 in.; wing 25·5 in.

BEWICK'S SWAN
Cygnus bewicki, Yarrell

This species, which is smaller than the Whooper, visits us regularly every winter, and is in some places the commoner of the wild Swans. In Scotland it is abundant in some seasons as it is also in Ireland, but on the coasts of England and Wales it is always rather scarce. It breeds in the Far North to the east of the White Sea.

It may be distinguished from the Whooper by its smaller size and the extent of the yellow on the beak, which does not quite reach the nostrils. Length about 46 in.; wing about 21 in.

THE MUTE SWAN
Cygnus olor (J. F. Gmelin)

In this country the Mute Swan is only met with in a state of semi-domestication, having been introduced at some early period of history. It is now, however, widely distributed throughout our islands. Inhabiting lakes, rivers, and ornamental waters, it feeds on aquatic weeds and grain, and is extremely useful in preventing an undue growth of weeds in ornamental ponds and lakes. The nest is a huge structure of straw and rushes, built upon the edge of the water, or in the centre of a reed-bed. The eggs, which vary in number from five to nine or ten, are of a uniform pale green, and are hatched after some five weeks' incubation.

The young, which are covered at first with greyish down, are carefully tended by both parents, and when tired nestle on their parents' back. In olden times the right to keep Swans on the Thames was granted by the King to many of the City Companies, and in the autumn of each year (a custom which is still continued) the young Swans are caught up and marked on the bill with the private mark of the Company to whom they belong. This is known as "Swan upping." The male is known as the "Cob" and the female as the "Pen," and the rules and regulations clearly state how the brood shall be awarded in the event of the Cob and Pen belonging to different Companies, while the landowner on whose ground they nest also comes in for a share.

At the nest the male Swan is very savage, attacking any intruder with his bill and with savage beats of his powerful wings; his mate, however, is very quiet and will allow herself to be pushed off the nest with no stronger protestation than a subdued "hiss."

This Swan is not mute as its name implies, but has a loud trumpet-like note, to which, however, it seldom gives utterance.

In a purely wild state, this species may be found breeding in Denmark and the south of Sweden, and it is a common breeding species in South-eastern Europe. From its northern breeding haunts it migrates in winter, many probably coming over to our shores.

The plumage is pure white; the bill reddish orange with a black knob at its base. This knob is much larger than in the male. The young are greyish drab. The so-called "Polish Swan" is a variety of this species, in which the young are white. Length about 56 in.; wing 27 in.

THE COMMON SHELD-DUCK
Tadorna cornata (S. G. Gmelin)

Although somewhat local in its breeding haunts, this species is fairly abundant round all our coasts in winter. It is a Sea-Duck, being seldom found far inland, and its food consists of small mollusca and marine insects, which it seeks on our flat estuaries and along the shore.

A rabbit-burrow in sand-dunes near the sea is chosen for a nesting-site, and lined with a little grass, to which is subsequently added an abundance of grey down from the body of the female. Occasionally it makes its own burrow, or other sites such as crevices between boulders or under furze bushes are selected. The eggs, generally ten in number, are creamy white. As soon as they are hatched the mother leads her brood to the shore, where they feed, making for the sea on the first sign of danger.

During the pairing season this bird is very noisy, the male uttering a short whistle, while both sexes run round each other with out-stretched neck, making a curious guttural chuckle.

In winter large flocks of these birds visit us from the Continent. These flocks may be seen resting out at sea by day and come in to feed on the soft ooze by night; they are of course more partial to flat and sandy parts of the coast, but may nevertheless often be found in small sandy bays on an otherwise rocky shore.

The head and neck are glossy bluish black; the scapulars and primaries black. There is a broad band of bright chestnut across the back and breast, and a black stripe along the centre of the under parts. Speculum green. The rest of the plumage is pure white. Legs flesh pink; bill crimson. The sexes are alike, but the female is smaller and duller. The male has a crimson knob at the base of his bill which swells up considerably during the breeding season.

The young bird lacks the chestnut band, the head and neck are dull brownish black, the scapulars greyish brown, and in its first autumn it assumes a plumage similar to the adult female, but duller. Length 25 in.; wing 13 in. Both sexes assume in July a much duller plumage, somewhat resembling that of the young in their first winter.

THE RUDDY SHELD-DUCK
Tadorna casarca (Linnæus)

The Ruddy Sheld-Duck is a South-eastern European species, breeding on the shores of the Levant and throughout Northern Africa, but it is rare on the north shores of the Mediterranean west of the Adriatic. It has several times been noted as a straggler to England, and in 1892 many flocks appeared in different parts of the country.

The general colour is a deep orange brown, the head being rather lighter. The male has a narrow black collar during the nesting season. The female is much paler on the head, the forehead, lores, and a ring round the eye being nearly white. Length 25 in.; wing 14·5 in.

THE MALLARD OR WILD DUCK
Anas boschas, Linnæus

This is at once our commonest and most beautiful Duck. Owing to drainage of fen-lands and higher cultivation it is, perhaps, not so abundant as formerly, yet there are few marshes or low-lying lands of any extent in our islands, which do not afford a home to a few pairs of this species.

It feeds chiefly by night on worms, aquatic insects, water weeds, and grain, and prefers ditches overgrown with weeds or shallow ponds to open stretches of deep water. Early in March it chooses a nesting site, usually on the ground and at no great distance from water, but exceptionally it has been known to nest in trees, faggots, stacks, and other elevated places. No nest is formed, but a cup-shaped hollow is scraped out, which is warmly lined with down after incubation commences. The eggs, usually ten to twelve in number, are pale greenish yellow, and are always carefully covered up by the Duck on leaving the nest. They hatch after twenty-seven days' incubation, and the young are then taken to the nearest water, on or near which they remain for about two months till they can fly. If, however, they are much disturbed they will be led away by their mother to a neighbouring piece of water, often at some considerable distance.

In a wild state the Mallard, as the male of this species is called, is strictly monogamous, and during the whole of incubation he will remain in the vicinity of the nest, warning his mate of the approach of danger, and accompanying her when she comes off to feed. Once the young are hatched he retires to some secluded and sheltered piece of water, where he assumes a dull plumage, somewhat resembling that of the female. During this period he becomes very skulking, rarely showing himself on the open water. When his dull or "eclipse" plumage has been assumed, he casts all his flight feathers at once, and for a short time becomes incapable of flight. These grow again in about a fortnight, and then in September he begins to assume his brilliant colours once more, and comes from his secluded retreat to join his comrades. In the winter they gather in large flocks, which resort to open sheets of water or the sea, flighting every evening to the marshes and shore to feed, and retiring again at daybreak to rest on the water.

It is these daily movements of Duck that are known to sportsmen as "flights," and they afford excellent shooting to the gunner concealed on their route. Vast numbers of this and other species of Duck used formerly to be taken in decoys, but partly owing to decrease in the numbers of the fowl, or still more to the increase of shooters, who frighten them away, few if any decoys are now worked at a profit in this country. A decoy is a pond in a suitable locality near the sea surrounded by trees and having two or four curved arms known as "pipes" running up at the different corners. These pipes are covered with netting, and end in a small bag net. The Duck are enticed up by tame birds and by means of a red dog that they follow out of curiosity. When some way up the pipe they see behind them the decoyman, who has hitherto been concealed by an ingenious arrangement of reed-screens, and rather than turn back and face him, they rise and fly up the pipe into the net. The whole operation must be carried out in silence so as not to scare the other birds on the pond, who remain in complete ignorance of their comrades' fate. Absolute quiet and plenty of food are the essentials for the successful working of a decoy. They are still used in Holland, where they form a considerable source of profit to their owners; their number is limited, and a licence has to be paid for each decoy.

After the brood can fly the Duck loses her primaries and becomes incapable of flight for a short time, but as soon as her quills are grown the whole family move off to join the flocks, which are now rapidly forming. Large numbers visit us yearly from abroad, and a spell of severe weather in midwinter still further increases their numbers.

The male has a glossy green head and neck, the latter being encircled by a narrow white ring; rump and tail coverts glossy greenish black, the four central coverts upturned; chest and breast deep chestnut; rest of under parts pale grey, vermiculated with black; bill greenish yellow; legs orange. The Duck is dark brown, the feathers having paler edgings. The young resemble the female, but the males have assumed their full dress by October. The male in eclipse has a plumage which approximates to that of the female. Length 23 in.; wing 11 in.

THE GADWALL
Anas strepera, Linnæus

The Gadwall is a scarce visitor to our shores, occurring irregularly along the east coasts of Scotland and England, but it is very rarely seen in the west or in Ireland. In a few places in Norfolk, where it was originally introduced, it breeds, and has of late years considerably increased both there and in the surrounding counties. In habits it resembles the Mallard. The eggs are usually ten in number and of a delicate creamy pink. It may be easily recognised on the wing by its white speculum.

On the Continent it nests in Central and Eastern Europe, its breeding range extending to the far north of Russia. It winters in the Mediterranean basin.

The adult male is greyish brown, with darker mottlings on the head and neck; back dark brown, with greyish markings; median wing coverts chestnut; greater coverts almost black. Under parts white, grey on the flanks and vent. Under tail coverts black. The female is marked with dark brown and buff much like a Wild Duck, but is recognisable by the _white_ speculum. The young somewhat resemble the female. The white speculum forms a distinctive mark of this species at all ages. Length 20 in.; wing 10·5 in.

THE SHOVELLER
Spatula clypeata (Linnæus)

This bird is by no means rare with us in winter, when large numbers come over from abroad. It is essentially an inland species, preferring small and sheltered pieces of water rather than wide open stretches. Its most characteristic feature is the large flattened bill with which it feeds on the surface-swimming animalculæ and other insects, the broad lamellæ of the mandibles forming an efficient strainer. When feeding three or four will often follow each other in a circle, each feeding in the other's wake. Of late years it has become more numerous as a breeding bird, and it now nests commonly in the Broads and other districts of Norfolk and the eastern counties. In Kent and the Midlands, Yorkshire and the North, it nests sparingly, as well as in some of the southern and eastern counties of Scotland. In Ireland it is a local but by no means scarce species. Except in the breeding season it is a very silent bird; when courting it moves its head up and down, uttering a low "took, took," which is answered by the female. The nest is generally placed at some distance from the water in the middle of a dry grass-field, where there is hardly any cover beyond a small patch of grass more luxuriant than the rest.

The eggs, which number from eight to ten, are pale greenish buff in colour. The female sits very closely, and the male remains in attendance at no great distance and accompanies her when she comes off to feed. The incubation period of this species is rather shorter than with most Ducks, and lasts between twenty-one and twenty-three days. The young are solely looked after by the Duck, and when first hatched their bills show no trace of the broadening and flattening, characteristic of the adult.

During the summer the Drake assumes an "eclipse" plumage, which somewhat resembles that of the Duck. In October he begins, _unlike_ most other species, to assume an "intermediate" plumage, in which the head is very dark but not metallic, and the white of the breast is obscured by dark transverse bars. The full plumage is not usually complete till the end of February or early in March.

In this country our breeding birds are practically resident, only shifting from their nesting-quarters when frozen out. The majority of birds met with, however, in winter are immigrants from the Continent, who leave us again in March.

The adult Drake in full plumage is a beautiful bird. The head and upper neck are metallic green; lower neck, breast, and scapulars white; back brown; shoulders pale blue; greater wing coverts white. The under parts are deep chestnut; speculum green; bill black; legs orange.

The Duck is dark brown, with light rufous buff edgings to the feathers. Shoulders bluish. The young at first resemble the Duck, and in November begin to assume the "intermediate" plumage described above, except that the breast feathers are spotted and not barred. It does not always assume its full plumage in the first year.

THE PINTAIL
Dafila acuta (Linnæus)

This species visits us in large numbers during the winter, arriving in September and not leaving our shores till April. During this period it is essentially a Sea-Duck, haunting shallow shores and estuaries, where it feeds on aquatic vegetation, crustacea, and other animal life brought in by each tide. It is commoner on the east coast than elsewhere owing to the large tracts of shore suited to its habits, but it may be found in smaller numbers on the west and in Ireland, wherever suitable localities exist.

It is only of late years that it has been known to nest in this country, a small colony having established themselves on one of the Scotch lochs. Elsewhere it breeds abundantly throughout Northern Europe, migrating southwards in winter. The nest is placed in a dry situation, at some little distance from the water. The eggs are rather elongated in shape and pale buffish green in colour.

The adult male has a brown head, greenish black on the nape. A white stripe runs down the neck on either side, merging into the white of the under parts. Back and flanks dark brown, mottled with grey. Wing coverts buff; speculum bronze green; tail black, the two central feathers much elongated; under tail coverts black; bill and legs slate grey. The female is of varying shades of buff and brown. The elongated neck and general shape of this species is sufficient to distinguish it from others of its family. The young resemble the female, and moult directly into their full plumage in their first autumn. The eclipse plumage of the Drake, which is dark brown above and smoky grey below, is lost about October. Length 26 in.; wing 11 in.

THE TEAL
Nettion crecca (Linnæus)

This is the smallest of our native species of Duck, and is fairly common throughout our islands at all times of the year, but its numbers are largely augmented in winter by the arrival of vast flocks from abroad. It may be found in winter near the mouths of rivers and shallow estuaries as well as inland; its food consists of grain, insects, worms, slugs, and molluscs.

It breeds throughout our islands, but more abundantly in the north. The nest is generally placed at some distance from water on a dry moorland or rough grass-field, and this species makes a rough nest of leaves and grass, lined with down. The eggs, eight to ten in number, are creamy white.

The male has the crown, nape, cheeks, and throat chestnut; an elongated patch of purplish green behind the eye, the rest of the upper parts vermiculated with black and white except the rump and tail coverts, which are black. Under parts white, the lower part of the neck and breast being spotted and sometimes of a yellowish tinge; flanks vermiculated with black. Speculum green and purplish black. Bill black, legs brownish grey. The female is mottled with brown and buff. The young resemble the female. The male in his eclipse dress, which is worn till late in October or November, resembles the female very closely, more so in fact than is the case with any other species. Length 14·5; wing 7·25 in.

THE AMERICAN GREEN-WINGED TEAL
Nettion carolinense (J. F. Gmelin)

This species has only occurred three or four times in these islands. The male differs from the Common Teal in having some greyish vermiculated feathers on either side of the breast, and the buffish white lines on the face are very slightly defined. The female cannot be distinguished from our native species. Length 16 in.; wing 7·25 in.

THE BLUE-WINGED TEAL
Querquedula discors (Linnæus)

This American species has been taken at least once in the United Kingdom. The male has the throat, forehead, and crown dark lead colour, and _a long crescentic patch of white_ in front of the eye. Cheeks and neck dull lavender grey. Length 16 in.; wing 7·25 in.

THE GARGANEY
Querquedula circia (Linnæus)

This is one of our scarcest species, coming to us as a summer immigrant from April to September, and remaining in a few suitable spots to breed. It is commonest in Norfolk, and may also be found in Hants, Kent, Suffolk, and Yorkshire. Elsewhere its occurrences are rare and only consist of stragglers on migration.

It breeds regularly on the Continent from Sweden southwards, becoming commoner in the east.

The nest is usually placed in a dry and often open situation, where there is but little cover. The eggs resemble those of the Teal, but are rather greener in tint.

The crown and nape of the male are dark brown, with a conspicuous white stripe passing backwards over the eye. Cheeks and neck brown ticked with white. Back dark brown; wing coverts bluish grey. Chin black; breast pale brown, with dark crescentic bars; remainder of under parts white. Vermiculated on the flanks. Speculum green; bill black; legs greenish. Female somewhat similar to Duck of the common Teal, but may be distinguished by the presence of a light stripe over the eye. The feathers of the back are dark with light margins, not barred as in the Teal, while the feathers of the breast are also entirely dark with white margins. Length 16 in.; wing 7·8 in.

THE WIGEON
Mareca penelope (Linnæus)

The Wigeon is one of our commonest winter visitors, arriving in large numbers from early in September onwards, and frequenting estuaries, bays, and tidal waters, but rarely wandering far inland. Although feeding also on marine insects and crustacea, it is chiefly a vegetable eater, living almost entirely upon _Zostera marina_.

In Scotland a good many pairs remain to breed, and during the summer it frequents high moorlands and inland waters. The nest is placed in a tuft of rushes or among heather, and the eggs, usually ten in number, are of a delicate creamy white. The note is a melodious whistle, which may be expressed as "whee you."

The male has the head and neck chestnut, with a broad buff stripe extending backwards over the crown; back grey uniformly vermiculated; throat and upper neck chestnut; breast white, vermiculated on the flanks; shoulders white; speculum green. In the eclipse plumage the head is dark chestnut, grizzled with brown; back brown, with chestnut edgings to the feathers; flanks chestnut; under parts white. The female is dark brownish grey above, lighter on the wing coverts, and white underneath. Length 18·5 in.; wing 10·5 in.

THE AMERICAN WIGEON
Mareca americana (J. F. Gmelin)

One or two examples of this species have occurred in this country at long intervals. It may be distinguished from our Wigeon by the forehead and crown being dull white, the cheeks and neck whitish, speckled with brown, and a green stripe passing backwards from the eye. The female has the head and neck yellowish white, speckled with black. Length 19 in.; wing 10·25 in.

THE RED-CRESTED POCHARD
Netta rufina (Pallas)

The Red-crested Pochard, whose nesting home is in South-Eastern Europe, though it also nests sparingly in the Rhone delta and Spain, is only a rare straggler to these islands, and most of the examples have been obtained in Norfolk, where as recently as last year, 1906, a flock of eight appeared, and needless to say were soon all shot.

It is a much larger bird than the Common Pochard, and may be distinguished by its rufous crest, red bill, and legs, though differing also in many other particulars. There are sixteen tail feathers instead of fourteen as in the genus Fuligula. Length 22 in.; wing 10·5 in.

THE COMMON POCHARD
Fuligula ferina (Linnæus)

With this and the preceding species we come to the second division of the Ducks, which are known as Diving Ducks, in contradistinction to the others which are known as surface-feeders, although quite capable, when alarmed, of diving. Diving Ducks may be recognised by having the legs placed further back on the body, thus rendering their progress on land rather difficult, and by the hind toe being lobed.

The Pochard is chiefly a winter visitor to our shores, occurring not uncommonly in most seasons, but being in some years much more numerous than in others. It chiefly frequents the sea-coasts, feeding on crustacea, molluscs, and a certain amount of marine or aquatic weeds, which it procures almost entirely by diving, but it is by no means exclusively confined to such localities, and is frequently met with on inland waters, provided they are of sufficient size. In spring the majority leave us for their breeding haunts on the Continent, but as a breeding species with us it is on the increase, and may be found in a certain number of favoured localities throughout England and Scotland. In Ireland, where it is fairly abundant during the winter, it has only been known to nest on a few occasions.
