Chapter X: Preface (10)

For a long time the breeding home of this bird was unknown, and even though it was discovered breeding over thirty years ago, it is only within the last four or five years that authentic eggs have been obtained and brought home from East Siberia. Its chief breeding-grounds are the Arctic regions of North America and the north of Greenland, and in winter it is found down both sides of the Atlantic.

In its food and habits it does not differ from its congeners, with whom it may often be found associating.

In winter the adult is grey on the upper parts and white below, with a few greyish flecks or bars on the upper breast. The young bird is browner, with light margins to the feathers of the back, the breast pale buff pink, with a few grey flecks. In nuptial plumage the head and neck are reddish brown, streaked with black; upper parts black, the feathers having marginal spots of chestnut and white tips; under parts chestnut, spotted with black; vent and flanks whitish, mottled with black. Length 10 in.; bill 1·5 in.; wing 6·5 in.

THE SANDERLING
Calidris arenaria (Linnæus)

From its habit of frequenting sandy stretches along our shores, and less frequently near inland lakes, this species has gained its trivial name. To this country it is only a migrant, young birds arriving from their northerly breeding-grounds as early as the middle of August; the old birds follow a week or so later, many of them still retaining traces of the nuptial plumage. They stay with us only a short time, and early in October the majority have left us to winter on the shores of the Mediterranean, very few remaining behind. In May the return migration commences, but they only stay for a very short time to rest and then continue their journey to the Far North.

Their food consists entirely of marine insects, sand-hoppers, and other crustacea, but at their summer-quarters large quantities of the northern saxifrage are consumed. It is very tame, allowing a close approach as it runs about on the sand, and appears conspicuously white among the Dunlins and other shore-birds with which it consorts. The note is a sharp "wick."

Its breeding range is entirely circumpolar, and the eggs are greenish, spotted with brown, not unlike miniature Curlew's.

In its winter plumage, in which it is most commonly met with in this country, the upper parts are pale grey and the under parts white. In its spring plumage the feathers of the back are black, with rufous margins; the chin, throat, and breast chestnut, with a few dark brown spots; vent white. In autumn the rufous edgings on the back of the old birds have almost entirely worn away. Length 8 in.; bill 0·9 in.; wing 4·7 in.

This species may always be distinguished by the absence of the hind toe.

In autumn the young have the back black, spotted with white; the under parts white, with traces of buff on the sides of the breast.

THE RUFF
Machetes pugnax (Linnæus)

Formerly this species used to be a regular summer migrant to our shores, breeding in the fen countries and other suitable places, but now, although a few birds visit this country in spring, and possibly a few may still breed, it is only as an autumn visitor that it will be generally found. Even on passage it can hardly be called common, but on our east and south coasts a good many pass through, halting merely for a few days. On the west and in Ireland it is decidedly rare and irregular in its appearances.

This species differs in its nesting habits from all other Waders. The males, who don a special showy ruff in spring, meet at their breeding-quarters on some raised mound and display their finery to the hens. Apparently they are very pugnacious, as they will often jump up and peck at another male, using their feet also after the manner of a gallinaceous bird, but on close observation it will be seen to be all "show," and we have never seen a proper fight between two males. On the arrival of a female the males spread out their ruff and remain motionless in front of her, and as she moves away they will jump up, and quivering with suppressed excitement again display their charms, to which she is apparently quite indifferent. Although said to be polygamous, the question is still open to doubt; from among her many admirers the female chooses one, and observations, so far as they go, seem to show that she only pairs with one male. A male, unless chosen, never pursues the female or interferes with her in any way, but trusts merely in his external beauty to attract her attention.

The nest is placed among rough herbage in a fairly damp place. It is a deep cup, well lined with grass and bents. The eggs, usually four but often three in number, are greyish green, blotched and spotted with various shades of brown. Except during the actual pairing the male takes no part in the housekeeping, and when the females are sitting the males may be seen together in flocks. In food and other habits this species resembles the majority of Waders.

In winter the sexes are alike, except that the male is very much larger than the female. The upper parts are of a uniform brownish, and the under parts brownish grey, with white margins to the feathers; belly white. The young resemble the adults but are darker on the back, the feathers of which have rufous or buff margins. The neck and breast are of a pale pinkish buff.

In spring, the male grows a long ruff on the neck and upper breast as well as a backwardly directed ear tuft on each side of the head. This ruff can be raised or depressed at will, and is of a variety of colours, hardly any two being exactly alike. The face also becomes covered with a mass of warty carbuncles. The feathers of the back and flanks are black, mottled, spotted, or barred with chestnut. The female has no ruff, but becomes darker on the back and breast. Length of male 12·5 in.; bill 1·5 in.; wing 7·25 in.: of female 10 in.; wing 6 in.

THE BUFF-BREASTED SANDPIPER
Tringites rufescens (Vieillot)

Several examples of this American species have been obtained on our shores. This bird is somewhat like the preceding species although much smaller, but it may always be recognised by the black markings on both sides of the inner webs of the primaries and secondaries. Length 8 in.; bill 0·9 in.; wing 5·25 in.

BARTRAM'S SANDPIPER
Bartramia longicauda (Bechstein)

This is another North American species, of which some eight or ten examples have been procured in this country.

Its general colour is pale tawny buff, barred and mottled with blackish. For a Sandpiper its tail is distinctly long and barred. Length 11·5 in.; bill 1·2 in.; wing 6·6 in.

[We may note here that the Sandpipers we have hitherto been dealing with have had the tail plain, whereas in the remaining ones, which belong to the genus _Totanus_, the tail is barred.]

THE COMMON SANDPIPER
Totanus hypoleucus (Linnæus)

This inland species, which is a summer migrant to our islands, is common and well distributed along the margins of lakes and on the gravel shores of streams and rivers. In the south and east, where suitable localities are scarce, it only occurs on migration, but elsewhere it breeds regularly.

The note is a plaintive "wheet, wheet, wheet," generally uttered on the wing. It is a very pleasing bird in its actions, running along the margin of the water and moving its body with a peculiar and delicate see-saw motion. When flying it remains fairly low down and follows the course of the stream, generally keeping over the water. Its food consists of worms, flies, and insects. The nest is placed on the ground, usually near the margin of some water, or on a rocky or gravel islet. The spot chosen is sometimes quite bare, or at other times thickly overgrown with brambles and rough vegetation. For a wading-bird it constructs a fairly substantial nest of grass and leaves, etc., and the eggs are of a pale clay buff, spotted with brown. The young when first hatched are greyish green with longitudinal dark stripes.

In August or early in September they begin to leave their summer-quarters and may then often be found in the salt marshes and on tidal ditches near the shore, but they do not remain there long, and by October they have all left, with the possible exception of a few stragglers that spend the winter in some of the south-western counties.

In summer the upper parts are bronzy brown, irregularly barred and flecked with blackish; sides of the neck and breast grey, with dusky streaks; rest of under parts white. In autumn the upper parts are uniformly brown, or nearly so, and the under parts lighter and with fewer streaks. The young have buff margins to the feathers of the back and lack the dark streaks on the throat. Length 8 in.; bill 1 in.; wing 4·25 in.

THE SPOTTED SANDPIPER
Totanus macularius (Linnæus)

This American species has been recorded on several occasions in these islands. It is closely allied to the Common Sandpiper and resembles it in plumage, but in the spring dress it is more spotted on the under parts, and in autumn it is greyer above, and lacks the bronzy tint of our native bird. All the secondaries are barred with ash brown, whereas in the Common Sandpipers the eighth and ninth are nearly white. Length 7 in.; wing 4·2 in.

THE WOOD SANDPIPER
Totanus glareola (J. F. Gmelin)

This species is a regular but somewhat scarce visitor to our shores on migration. In Ireland and the west it is extremely rare, but in the south-east corner of England it occurs in small numbers yearly, especially in autumn. Formerly a few pairs used to nest in one or two suitable localities, but they have long ceased to do so. In the west of Europe it does not breed south of the Baltic, but in the east it breeds in the valley of the Danube and also possibly in Northern Italy.

The nest is placed on the ground in a marshy spot, and when they have eggs or young the birds are extremely noisy if their haunts are invaded. In this country it is generally found on salt marshes near the sea and very rarely inland.

The sexes are alike: the back brown, spotted with white; upper tail coverts white; shafts of the quills dusky, except that of the _outermost one_, which is _white_. Under parts white, streaked with brown on the throat and breast, the flanks being barred with the same colour. Axillaries white. The young bird is similar, but the white spots are larger and more elongated, and the outer tail feathers are barred on both webs instead of on the outer one only. Length 8·5 in.; bill 1·1 in.; wing 5 in.

GREEN SANDPIPER
Totanus ochropus (Linnæus)

This is a much commoner species than the last, and haunts inland streams, especially in the neighbourhood of trees and woods. It is most numerous during the autumn migration, but many pass the winter with us, and it has been suspected of breeding on more than one occasion, but positive proof of this has not been forthcoming.

In the north and west of Scotland it is scarce, but otherwise it is widely distributed throughout the country. On the Continent it nests in marshy woods from the Arctic Circle southwards to Central Russia, Poland, and East Germany, its migrations extending to Africa in the winter.

In its nesting habits it differs from all others Sandpipers, for it lays its eggs in the deserted nest of some other bird, generally that of a Thrush, Blackbird, or Jay. The eggs are greenish grey, with small brownish spots. Its food consists of worms and insects.

In plumage it very closely resembles the preceding species, but the back is darker and the spots much more minute. It may, however, always be distinguished by the _dusky_ shaft of the _outermost_ primary and the brownish black axillaries. In young birds the spots on the back are less plentiful and of a more buffish tint. Length 9·5 in.; wing 5·5 in.

THE SOLITARY SANDPIPER
Totanus solitarius (Wilson)

This is an American species, which, like so many of its New World congeners, has occasionally and at long intervals straggled to these islands.

Its nearest ally is the preceding species, from which it may be recognised by having _all_ the tail feathers, except the central pair, boldly barred with black. Length 8·25 in.; wing 5·2 in.

THE YELLOWSHANK
Totanus flavipes (J. F. Gmelin)

Two examples of this American species have been obtained, the first near Nottingham and the second at Marazion in Cornwall.

In general appearance it is not unlike a young Redshank, but the legs are longer and more slender, and the axillaries are _barred_ and not white. Length 10·75 in.; wing 6 in.

THE GREATER YELLOWSHANK
Totanus melanoleucus (Gmelin)

A solitary example of this species was shot on the 16th September 1906 at Tresco in the Scilly Islands. It is an American species and is not unlike a very large Redshank, but the legs are longer in proportion and yellow in colour. Length 12·15 in.; bill 2 in.; wing 8 in.

THE COMMON REDSHANK
Totanus calidris (Linnæus)

The Redshank is a common breeding species in suitable localities throughout our islands.

In winter it occurs abundantly round all our coasts and causes much annoyance to shooters from its habit of flying up on the least alarm and warning all the other less wary fowl, with its shrill "tui too too."

The nest is usually situated on some inland marsh or low-lying grass field intersected with ditches. It is a very slight structure of grass and bents well concealed in a tussock of grass or tuft of rushes. The four eggs are of a pale stone colour, mottled and blotched with rich reddish brown. During the nesting season this bird becomes very noisy, and if the nesting site be approached, especially after the young are hatched, they fly round the intruder or sit on some bank, calling out vigorously all the time. It is a most interesting sight to take a sporting dog to where they have young and watch the way in which time after time these birds will decoy the dog away by fluttering under his very nose until they have led him to what they consider a safe distance, when they will spring in the air and with a cheery note return to their brood. This habit is common to many species and orders of ground-nesting birds, but unless we take a keen hunting dog with us we shall fail to realise what an excellent device it is for safeguarding the young from mammalian vermin. The food and habits of this species call for no special comment, as it does not greatly differ from its congeners.

In winter the adult is greyish brown on the back; secondaries nearly white; rump and under parts white, with a few dark streaks on the neck and breast. Bill black with a red tip; legs red.

In summer the upper parts are yellowish brown barred and spotted with blackish, the under parts white, profusely streaked on the neck and sides of the breast with ash brown, the flanks being barred with the same colour. Length 11 in.; bill 1·8; wing 6·25 in.

The female resembles the male, and the young may be recognised by the feathers of the mantle having buff spots and the legs being yellow.

The white secondaries are very conspicuous in flight.

THE SPOTTED REDSHANK
Totanus fuscus (Linnæus)

The Spotted Redshank is a rare migrant on both the spring and autumn migrations. In Scotland, Ireland, and the west of England it is almost unknown, but in the eastern counties a few probably occur every year on passage, but their stay is of such short duration that they are often unnoticed.

It breeds in the north of Scandinavia and Russia, laying its eggs in very dry situations at a considerable distance from its marshy feeding-ground. The young are, however, taken to the marsh as soon as they are hatched.

In summer the male has the upper parts black mottled with white, except the rump, and upper tail coverts, which are white, barred with black. Under parts black. Bill black, red at base of lower mandible; legs and feet deep red. The female at this season often has a white chin. In autumn the upper parts and neck are ashy brown mottled with white; under parts white. The young differ from the autumn plumage of the adults in having the chin white and the rest of the under parts thickly barred with ash brown. Length 13 in.; wing 6·6 in. This species lacks the white wing bar.

GREENSHANK
Totanus canescens (J. F. Gmelin)

In a few places in Scotland where large tracts of pine forest exist some small boggy swamps varying in size from two or three acres to perhaps half an acre, may be found situated in the midst of the woods. These swamps form the summer home of the few Greenshanks that nest with us. The eggs are placed on a tussock in the centre of one of these bogs, so that to reach them is by no means an easy matter, and so cunning are these birds that they are seldom seen feeding on the swamp where they nest, but prefer to dine elsewhere. The eggs are generally of a light stone colour, boldly blotched and marked with darker brown. As soon as the young are hatched the parents remain in constant attendance, and should any one disturb the peace of their solitude, fly round, calling out incessantly. Amid such surroundings, therefore, be it in Scotland, Sweden, Finland, or elsewhere, the Greenshank is born, but as soon as he is able to fly at about five weeks old he departs with his parents for the nearest sea-shore where the mud-flats exposed at each tide afford him abundant nourishment. He is a wild and restless bird, and continually utters his clear "tui-tui" when on the wing. As a rule he is more partial to ditches filled and emptied at every tide than a broad flat expanse of mud, and by walking quickly along a ditch he may often be closely approached and watched as he probes the soft ooze for worms, shrimps, sand-hoppers, or anything that may come handy. At the least sign of danger, however, he is off, calling out as he rises and displaying a very conspicuous white rump. Although liking to associate with others of his kind, his wild flight soon breaks up the family party, so that by the time he reaches our shores in August and September it is generally in twos and threes. The abundance of food on the shore has not been without its effect, and he is at this time of year exceedingly fat, doubtless a wise provision, as both old and young are moulting and migrating, which must be a serious tax on their system. They stay but a short time with us, and by the beginning of October the last of them has gone and their ringing "tui-tui" no longer enlivens the shore. In April they will return, but they are then anxious to reach their summer home, and brief as is their passage in autumn it is still shorter in spring, and if we wish to see them then it must be at their home in Scotland or farther north.

In summer the back is nearly black, each feather being margined with white; rump white; head white streaked with dark brown. Under parts white with a few blackish streaks on the throat and upper breast. In winter the back is greyer and the under parts are pure white. The sexes are alike. The young are browner on the back, and have buffish margins to the feathers. Length 14 in.; wing 7·25 in.

THE RED-BREASTED SNIPE
Macrorhamphus griseus (J. F. Gmelin)

Some half-dozen examples of this American species have been met with in England, all of them during the autumn months.

At this time of year, except in size, it resembles a Dunlin; but in spring the under parts are chestnut, spotted on the breast, and barred on the flanks with dark brown. The feathers of the back are black, edged and barred with rufous. Rump and upper tail coverts white barred with black. The shaft of the outermost primary is pure white. Length 10 in.; wing 5·5 in.

THE BAR-TAILED GODWIT
Limosa lapponica (Linnæus)

On migration this species visits us in fair numbers, being found on low sandy shores and sheltered estuaries. A few remain throughout the winter, but by far the larger number pass on to Africa after a short sojourn. In May there is a return migration, especially along the east coast, the birds being then in full nuptial plumage.

It breeds in the northern portions of Europe, and in winter it is found throughout Southern Europe as well as in Africa. The note is a loud "louey, louey."

In autumn the sexes are alike, and the general colour is brownish grey above and white below. The tail feathers are brown with no bars, but the tail coverts are barred at all seasons.

The young have a shorter beak than the adults, and are brown chequered with buffish above and dull buff below. The tail feathers are broadly barred.

In spring the male has the back blackish with tawny markings, the head and neck chestnut with dark streaks. Whole of the under parts deep chestnut, the sides of the breast spotted with brownish black. Rump white. Tail whitish with brown bars. Length 15·5 in.; bill 2·25 in.; wing 8 in. The female is much larger and has very little of the ruddy tint.

THE BLACK-TAILED GODWIT
Limosa belgica (J. F. Gmelin)

During the first half of last century this species used to nest in small but diminishing numbers in the fens and marshes of Lincolnshire and East Anglia. It is now only met with on passage, and even at such times it is by no means common, and in Scotland and Ireland it is scarce and its visits very irregular. On the Continent it breeds in South Scandinavia, Central Russia, Poland, North Germany, Denmark, and Holland, migrating during August to the Mediterranean basin.

Their food consists of insects and worms, which in this country are chiefly sought for in marshes near the shore. In the autumn plumage the general colour is ash brown above and greyish below. There is a conspicuous white wing bar, and the tail feathers are mostly black with white bases. In spring they have the mantle brown, mottled with black; head, neck and breast pale chestnut, the latter being barred with black. The female is considerably larger and rather duller than the male. The young in their first autumn resemble their parents, but have the neck and upper breast tinged with buff. Length 16 in.; wing 9 in.

THE CURLEW
Numenius arquata (Linnæus)

The Curlew is an abundant resident throughout the United Kingdom. In the winter it is essentially a shore-bird, moving about in large flocks, which may be found in the meadows and pasture-lands near the coast; these flocks journey to the shore twice daily to feed on the mud or rocks left bare by the ebbing tide. In April it leaves the coast to nest on the heath-covered moors, and though it breeds in larger numbers in Scotland it is well distributed in the north and west of England and Ireland.

The nest is a shallow "scrape" with hardly any lining, and is placed among the heather or in a grass field. The four eggs are very pyriform in shape and are olive green in colour blotched with brown; the duties of incubation are undertaken by both sexes. It is extremely wary, rising on wing at the least alarm and calling out its loud "cour lie," which may be heard a considerable way off. Its food consists of worms, slugs, snails, and other insects, and when on the shore, small fish and crustacea are added to the bill of fare.

The general colour is a pale brown, with dark streaks; rump, vent, and upper tail coverts white. In winter the under parts are very pale in colour, almost white. The female is larger and the young in their first plumage are spotted rather than streaked on the back. Length 21-26 in.; bill 4·7-6 in.; wing 11·5-12·25 in.

THE WHIMBREL
Numenius pheopus (Linnæus)

The Whimbrel only passes through these islands on migration, though a few pairs breed on the Orkneys and Shetlands. The spring passage generally takes place in May, from which it is known in some countries as the May-bird. In habits and food it closely resembles the Curlew, but its note is very different, being a rather melodious rippling whistle, which may be syllabled as "telly, telly, telly, tet." The fells of Arctic Europe form its chief nesting-grounds, whence it migrates in winter to the shores of the Mediterranean.

In plumage it is very similar to the Curlew, but may always be distinguished by having the crown of a uniform dark brown with a pale stripe down the centre. It is also a much smaller species. Length 17·5 in.; bill 3·4 in.; wing 10 in.

THE ESKIMO CURLEW
Numenius borealis (J. F. Forster)

The home of this bird is in Arctic America, and some eight or nine examples have been procured in this country.

In appearance it is rather like a small Whimbrel, but it may be recognised by the absence of barring on the primaries, no white on the rump, transverse arrow-head markings on the under parts, and the axillaries being chestnut barred with brown. Length 14 in.; wing 8·25 in.

THE BLACK TERN
Hydrochelidon nigra (Linnæus)

Up till the middle of last century the Black Tern was a regular summer visitor to our shores, remaining to breed in the fens and marshes of England. For the last forty years, however, it has only occurred on passage, the adult birds passing through in April and May, and flocks in immature plumage being found along the east coast in the autumn. To the west of England and Scotland it is a very irregular visitor, and the same may be said of Ireland.

It nests in colonies on inland marshes, the nest being an accumulation of decaying vegetation floating on the surface of the water. The eggs, three in number, are olive green blotched with dark brown. Its food consists largely of aquatic insects and their larvæ, dragon-flies and such like, but it also feeds readily on small fish.

South of the Baltic it breeds in suitable localities throughout Europe, migrating from its more northerly summer quarters to Africa.

The adult in summer has the head, neck, and under parts dark greyish black, the rest of the plumage slate grey, except the vent and under tail coverts, which are white. Bill black. In winter the forehead, nape, chin, throat, and under parts are white. The young resemble the adults in winter, but the upper tail coverts are lighter and the back and wing coverts are greyish mottled with brown. Length 10 in.; wing 8·5 in.

THE WHITE-WINGED BLACK TERN
Hydrochelidon leucoptera (Schinz)

This species, which is nearly allied to the preceding, breeds in the marshes of Central and South-eastern Europe. It is a very scarce and irregular visitor to our eastern and south-eastern shores, especially in spring.

In habits it resembles the Black Tern, from which it may be distinguished in summer by its red bill, white tail and tail coverts, and whitish wing coverts. The young may be distinguished from those of _H. nigra_ by their longer toes and much paler rump and tail. Length 9·5 in.; wing 8·25 in.

THE WHISKERED TERN
Hydrochelidon hybrida (Pallas)

This is a more southern species than its congeners, breeding in Spain, on the delta of the Rhone, and eastwards in Turkey, Greece, and South Russia. To our shores it is a very rare visitor, some half-a-dozen specimens only having been obtained.

In summer it is not unlike the Black Tern, but it may be recognised by the bill, which is stouter and red; the black of the head and nape is sharply contrasted with the grey of the back. A broad white stripe runs backwards from the base of the bill. Chin and throat grey, shading to black on the belly. In winter the forehead and under parts are white. Length 11·5 in.; wing 9·25 in.

THE GULL-BILLED TERN
Sterna anglica, Montagu

With this species we come to the true Terns or Sea-Swallows, the preceding species being known as Marsh Terns. The Gull-billed Tern is only a very scarce straggler to our shores, being a southern European species though occurring yearly as far north as Denmark.

In habits there is nothing to distinguish it from our commoner species.

In summer the adult has the whole of the upper parts, including the tail, pearl grey; head and nape dense velvety black; primaries blackish. Under parts pure white; bill and legs black. In winter the head is white streaked with black. Length 15·5 in.; wing 13 in.

THE CASPIAN TERN
Sterna caspia, Pallas

This large Tern is, like the preceding, only a rare straggler to our shores. It nests in Denmark and various islands on the Baltic, as well as in the Mediterranean basin eastwards to the Aralo-Caspian area.

Plumage much as in preceding species, but the tail nearly white. Bill vermilion red; legs black. Length 20 in.; wing 16 in.

THE SANDWICH TERN
Sterna cantiaca, J. F. Gmelin

This species arrives on our coasts about the middle of April and at once repairs to its breeding-stations. In England these are very few in number and mostly in the north, but occurring equally on the east and west coasts. In Scotland the colonies are rather more numerous, while Ireland can only boast of one in the north.

It nests on the bare shingle, the nests being usually placed quite close to each other. Two or three eggs of a pale stone colour, spotted and blotched with reddish brown and black, form the clutch.

Like all Terns, this bird is a powerful flier, and seizes the fish on which it feeds by plunging into the water with considerable force. Its note is a loud and harsh "kirhitt," which may be heard some way off and often enables this species to be detected when among other Terns. It leaves our shores as soon as the young are well on the wing, and though a few stragglers may occur on the coast during the autumn it is by no means a common species, and needs all the protection it can get, if it is to remain an annual summer visitor to our shores.

The adult male in summer has the crown of the head black; the rest of the upper parts pearl grey; rump, tail, and under parts white, the breast being suffused with a delicate rose tint which soon fades after death. Bill black with a yellow tip. Legs black. The female is similar but slightly smaller. In autumn the back of the head and nape are white, the latter being lightly mottled. In the young the head is white mottled with black. The feathers of the back and wing coverts have black and brownish crescentic markings and white tips. The tail is also marked with angular lines of black, the outer feather being almost entirely greyish. Length 16 in.; bill 2·5 in.; wing 12 in.

THE ROSEATE TERN
Sterna dougalli, Montagu

This Tern still nests in small numbers round our shores, but it is extremely scarce and somewhat erratic in its choice of breeding-quarters, which often vary from year to year. It arrives very late in May, and leaves our shores as soon as the young can fly, so that it is not often met with on migration. It breeds sparingly on the coast of France, but its chief breeding-quarters are along the Atlantic coast of the United States.

In general habits it resembles its congeners, but it is an exclusively sea Tern, obtaining most of its food some distance out at sea.

In plumage it is almost indistinguishable from the two following species, but it may be recognised at all ages by the white inner margins to the primaries reaching the tip and even some little way up the outer web. The bill in the breeding season is black; legs and feet red. Length 15·5 in.; wing 9 in.

THE COMMON TERN
Sterna fluviatilis, Naumann

This species arrives in May and nests in colonies round the whole of the coast as well as on some inland waters. In England it is the commonest Tern, but in Scotland and Ireland the Arctic Tern is almost if not quite as numerous, and both species may often be found nesting on the same island or beach.

Its food consists of small fish and crustacea, which it catches after the manner of all Terns by dropping down on them with closed wings from a moderate height.

They nest in colonies on rocks, shingle beaches, or near the margins of large inland waters, and very little attempt at a nest is made, though this species almost invariably gathers a few bents together. The eggs are usually three in number, often only two, and are very variable in colour, being as a rule greenish or stone buff, with brown and grey spots and markings.

The note is a sharp "kik-kik," but during the nesting season they utter a loud "ee-arre," which is rather characteristic of this species.

The young are covered with pale brown down mottled with black, and leave the nest as soon as they are hatched, but they remain near the spot until they are fully fledged and well able to fly, as they are during that period entirely dependent on their parents for food.

Soon after the young can fly, old and young gradually disperse along the coast, slowly working southwards till by the beginning of October the last straggler has left for its winter quarters in Africa.

In summer the adult has the crown of the head and nape black, the rest of the back pearl-grey; rump white; tail feathers white with greyish outer webs. Under parts white tinged with grey. Bill orange red with _horn-coloured tip_; legs coral red. The sexes are alike. In winter the forehead is sprinkled with white and the under parts nearly pure white. The young in its first plumage has the head white; spotted with blackish brown, the feathers of the back pale pearl-grey barred with buff or brown and tipped with white; by late autumn, however, the back is pure grey with the exception of a dark band along the carpal joint. Bill and legs yellowish. Length 14·25 in.; bill 1·7 in.; tail 6·5 in.; wing 10·5 in.

THE ARCTIC TERN
Sterna macrura, Naumann

Except in a few minor points of plumage and in its distribution this species is the counterpart of the preceding one. In England it is only met with on migration, though a few pairs may nest in the north, but in Scotland it is the commonest Tern, breeding in increasing numbers northwards. In Ireland it breeds commonly, especially on the wind-swept islets of the north and west. Elsewhere it breeds in circumpolar regions, and has been met with in winter in Antarctic seas, so that it has a latitudinal range of from 82° N. to 74° S., probably the largest range recorded for any one species.

Its nesting habits are similar to those of the Common Tern, and as a rule it collects absolutely no materials for a lining, but lays its eggs in a shallow "scrape" or even on the bare rock. The eggs are indistinguishable in colour from those of the Common Tern, but are on the average slightly smaller. To the experienced ear the note is also rather different, but that difference is too slight to be expressed on paper.

This species may be distinguished from the preceding species by its blood-red bill, which is _not_ darker at the tip, and the shorter tarsi. The under parts, especially in summer, are much darker, and the stripe on the inner web of the flight feathers is narrower and darker than in _S. fluviatilis_. In other respects these species are almost indistinguishable. Length 14·5 in.; bill 1·6 in.; tail 7·5 in.; wing 10 in.

THE LITTLE TERN
Sterna minuta, Linnæus

This is the smallest of our Terns and is a summer visitor, breeding in fair numbers on shingle beaches round the coast but becoming scarcer in the north.

It may often be seen fishing in small parties at the tidal mouth of some small stream, especially when the tide is flowing. At such times it flies slowly towards the sea till it sees a fish, when it stops, hovers for a moment, and then drops on its prey, rising immediately from the water to resume its search; after progressing a short distance it will wheel back and return to its starting-point.

The eggs are laid on the bare sand or shingle without any attempt at a nest; they are usually three in number and of a pale stone colour spotted with grey and brown. The note is a sharp "kik."

In summer the head and nape are black, except for the forehead, which is white. Upper parts grey, tail and under parts white. Bill yellow with a black tip. Legs orange.

The young have the head white, streaked with blackish brown, mantle grey with buffish tips, under parts white. In their first autumn plumage they are very similar to the young of the Sandwich Tern, the feathers of the back being marked with black, brown, and white. Length 9 in.; wing 6·75 in.

THE SOOTY TERN
Sterna fuliginosa, J. F. Gmelin

Stragglers of this tropical species have on two or three occasions been met with on our coasts.

There is a white band across the forehead, which extends backwards over the eye on each side; rest of the upper parts deep sooty black; under parts white; outer web of outer tail feathers white. Bill and legs black. Length 17 in.; bill 2·1 in.; tail 7·5 in.; wing 11·75 in.

THE NODDY
Anous stolidus (Linnæus)

Like the former, this is a tropical species, which has on two occasions wandered to our shores.

The general colour is a dark chocolate brown all over except for the head, forehead, and crown, which are lavender grey. Length 16 in.; wing 10·5 in.

SABINE'S GULL
Xema sabinii (Joseph Sabine)

This circumpolar species is a very rare autumnal visitor to our shores. Its chief breeding-grounds are the Arctic regions of North America, whence it migrates southwards, in winter.

The adult has a slate grey back; the head and neck are very dark grey, tail and under parts white. In winter the forehead and crown are white. In their first autumn the young are ash grey on the occiput, nape, and back. The tail feathers have broad black tips. Length 13 in.; wing 10·75 in.

This species may always be recognised by the forked tail.

THE WEDGE-TAILED GULL
Rhodostethia rosea, Macgillivray

This extremely scarce Arctic Gull is said to have been obtained in Yorkshire on one occasion. It may be recognised by the wedge-shaped tail.

The adult is grey on the mantle; the rest of the plumage, except for a narrow black ring round the neck, is pure white. Length 13·5 in.; wing 10·25 in.

BONAPARTE'S GULL
Larus philadelphia (Ordigny)

This is a common North American species, of which some three examples have been taken in the United Kingdom.

In summer the adult has the head and neck black; mantle grey; tail and under parts white. The black on the head is lost in winter. Length 14 in.; wing 10·25 in.

This species may always be recognised by the white margins to the inner webs of the two outer primaries.

THE LITTLE GULL
Larus minutus, Pallas

This species, which is the smallest of our Gulls, is an irregular autumn visitor to our shores. It breeds in Northern Russia and possibly on some of the islands of the Baltic, migrating in winter to the Black Sea and Mediterranean.

In summer the head and neck are black; mantle grey, primaries grey edged with white, rest of plumage white except the underside of the wing, which is black and forms a distinctive characteristic in the adult. Length 11 in.; wing 8·75 in.

THE BLACK-HEADED GULL
Larus ridibundus, Linnæus

The Black-headed Gull is an extremely abundant species throughout the United Kingdom at all times of the year. In summer it resorts to various inland marshes and bogs, where it nests in immense colonies, some of which have been in use for centuries. In autumn and winter it is found all along the coast and up tidal rivers, a great many coming to London, where they are extremely tame and show great agility in catching bread and other morsels of food thrown to them by pedestrians. The bird is practically omnivorous. When inland it follows the plough and feeds largely on worms and beetle grubs which are thus laid bare; but on the sea-shore, fish, crustacea, marine insects, and garbage are greedily devoured.

The nests are placed in a very wet and boggy place, surrounded, if possible, by water, but small ponds or tarns in marshy land are chosen in preference to large sheets of water. The nest is a large untidy heap of weeds and sticks. Four eggs, which are greenish, spotted and blotched with various shades of brown, form the usual clutch. The young hatch after about three weeks' incubation, and are covered with pale brown down mottled with black. They leave the nest when two or three days old, but for a week or ten days at least are entirely dependent on their parents for food; after that, however, though still fed by their parents, they pick up a good deal for themselves. They fly when about six weeks old. This gull is extremely noisy at all times, but when the nesting-ground is approached the babel of harsh screams is deafening. Although usually settling on the ground, this bird can perch with ease, and does so not infrequently when at its breeding haunts.

The sexes are alike, and in winter have the back pearl grey, wing feathers white with dark margins to the inner webs, head white with two indistinct dark crescents connecting the eyes and ears respectively, rest of the plumage white. Bill and legs white. In summer the head, with the exception of a narrow white circle over the eye, is dark brown. Bill and legs much darker than in summer. The young in their first plumage are mottled with pale brown, but soon become like the adult except for a black bar on the tail and pale brown wing coverts. The brown head is often only partially assumed in their first summer. Length 16 in.; wing 12 in.

THE MEDITERRANEAN BLACK-HEADED GULL
Larus melanocephalus, Natterer

This southern species has only once been taken on our shores, though, as it visits the west of France not uncommonly, there is no great improbability in its occurrence here. Its true habitat is the Mediterranean basin.

It is slightly smaller than the preceding species, and the head is jet black, _not_ brown. The beak is also stouter. In young birds the first five primaries are chiefly dark brown, whereas in our species the shafts and contiguous portion of the inner webs are white. Length 15·5 in.; wing 11·75 in.

THE GREAT BLACK-HEADED GULL
Larus ichthyaëtus, Pallas

This species is found in Egypt, the Levant, the Red Sea, and Persian Gulf, and only one example is known to have occurred on our shores.

The large size and black head are sufficient to distinguish this species when adult; young birds may be recognised by the clear-cut dark band across the tail and by the white margins to the outer webs of the secondaries. Length of male 26 in.; wing 19 in. The female is much smaller.

COMMON GULL
Larus canus, Linnæus

This bird is by no means the commonest of our Gulls, but may nevertheless be found in fair numbers along all our coasts in winter.

It does not breed in England, and in Ireland there are comparatively few colonies; but in Scotland, on the low islets round the coast as well as on the lochs and tarns inland, it is abundant in summer as well as in winter.

It usually nests in small colonies of six or eight pairs on some low-lying islet near the coast or on a lake, but it avoids during the breeding season precipitous coasts and exposed situations. The nest is placed on the ground and composed of a few bits of grass, seaweed, and heather without any attempt at concealment. The eggs, usually three in number, are olive brown streaked and spotted with blackish; like most Gull's eggs, however, they vary considerably in colour. In food and habits it closely resembles the Black-headed Gull. Its ordinary note is a harsh cry, but during the nesting season it tries, somewhat feebly, to imitate the well-known call of the larger Gulls.

In summer the plumage, with the exception of the wings and mantle, is pure white. The mantle and most of the wing feathers are delicate bluish grey, but the three outer pairs of flight feathers are black with a white mirror towards the tip. Bill greenish with yellowish tip, legs greenish yellow. The sexes are alike, and in winter the head is flecked with brown. The young in autumn may be distinguished by the black bar on the tail and brownish wing coverts. Length about 17 in.; wing about 15 in.

THE HERRING GULL
Larus argentatus, J. F. Gmelin

This is the commonest of all our Gulls, and may be found abundantly throughout the year, round all our coasts. It nests in colonies, usually on the ledges of precipitous cliffs, although small low islets are occasionally resorted to. The nest is composed of grass, seaweed, and other vegetable débris, and the eggs, three in number, are greenish brown with brown and grey markings, but they are not infrequently of a uniform pale blue. Incubation is undertaken by both sexes. The young as a rule remain in or near the nest till fully fledged, but when the nest is low down near the shore they leave it much sooner. The Herring Gull is practically omnivorous; fish, rats, crustacea, and garbage thrown up by the tide are all equally appreciated, and when nesting near colonies of Guillemots and Cormorants it systematically hunts the ledges and devours any uncovered eggs it can find. During the nesting season it is very noisy and utters a variety of cries; at times the head is bent right down and suddenly thrown up in the air with a loud "ollick, ollick," which cry is taken and repeated all over the colony. Young Gulls first commence to utter this note, which is not peculiar to the nesting season or to this species, at about three months old. If the colony be approached the birds utter a short "ow-ow"; the pairing note is a deep "mau," not unlike a cat's "miau," and a soft purring "ououou," the latter note being uttered while the bird sits down and toys with grass or other material at hand.

The adult in summer has the mantle French grey, secondaries grey tipped with white, outer primaries black with white tips and large subapical "mirrors." The rest of the plumage is white. Bill yellow with a red patch at the basal angle. Legs flesh-coloured. The female is said to be smaller than the male, but the difference is not always very apparent. In winter the head and neck are streaked with brownish.

The young in the first autumn are mottled all over with pale brown. They do not become fully adult until their fourth year, though they may sometimes breed in their third year. The adult plumage is assumed gradually, and there is much individual variation both as regards the time and method in which it is assumed. As a rule, however, some grey feathers appear on the back during the first summer; after the second autumn moult the under parts are chiefly white flecked with brown, but the back is chiefly brown. In their second summer much of the brown on the head and under parts is lost, the mantle becomes very grey, and the bill begins to show signs of yellow. The wing coverts and tail are, however, still very mottled.

After the third autumn moult the under parts, head, and neck are much as in the adult birds but more thickly mottled, the back chiefly grey, but the wing coverts, wings, and tail are still very brownish. In their third summer they are practically in adult plumage except for the wings and tail and a remnant of black on the bill. After the fourth autumn moult they are in full adult plumage except that the bill may still show some traces of black and occasionally the tail has some brown flecks, but by the time their fourth summer comes round they are in full adult plumage and breed.

Immature birds are seldom seen among colonies of adults during the summer, and it is still somewhat doubtful where they spend the summer; possibly round some islets out at sea where food is plentiful. Length 24 in.; wing 17 in.

THE LESSER BLACK-BACKED GULL
Larus fuscus, Linnæus

Very closely allied to the Herring Gull, this species is tolerably common everywhere, but is rather more local in the breeding season. In England it nests but sparingly and only in the west, but in Scotland it becomes much more abundant, and in some districts commits considerable havoc among the game-birds on the moors.

It chooses for its breeding-quarters some grassy slope on the top of the cliffs or on an islet in one of the numerous firths in the west of Scotland. In Ireland it is generally distributed and nests sparingly round the coast. In all its habits this species so closely resembles the Herring Gull that further description is unnecessary.

The adult only differs from the preceding species in being black on the mantle and wing coverts, and in the colour of the legs, which are yellow. Length 22 in.; wing 16 in.

It is almost impossible to distinguish the young of this species in their first autumn.

THE GREATER BLACK-BACKED GULL
Larus marinus, Linnæus

This species may be found during the winter on almost any part of our shores, but it is by no means so abundant as the Herring Gull.

As a breeding species in England it is rather scarce, chiefly owing to lack of suitable places, but in Scotland it is abundant. It is a bold and majestic species, with a fine soaring flight, but we must acknowledge that it is terribly destructive to weakly lambs and young water-fowl. Practically omnivorous, nothing comes amiss to this rapacious bird, and its food consists largely of carrion and other refuse of the shore. Although it has often been denied, this and other species of Gulls can completely immerse themselves and pick up food from the bottom in at least three feet of water, and we have repeatedly observed them do so in captivity. Having marked some food at the bottom of the water, they rise to a height of about four feet and forcibly precipitate themselves into the water with half-open wings; they are nevertheless extremely buoyant, and occasionally bob up on to the surface again before they have attained their object.

An isolated "stack" or islet in a loch is commandeered by a pair of these birds for their summer home. The nest, composed of grass and rubbish, is usually placed on the highest point. They lay two or three eggs, which are stone buff in colour, blotched and spotted with light brown and grey.

The most usual note is a deep "ow, ow, ow." In plumage the adult is almost the counterpart of the preceding, but the legs are flesh-coloured. Length 23 in.; wing 19 in.

The young are mottled and barred with various shades of brown and buff, but are rather lighter in colour than those of the Herring Gull. The adult plumage is assumed by precisely the same stages as in the other species, and they may occasionally become fully adult in their third summer.

THE GLAUCOUS GULL
Larus glaucus, O. Fabricius

This large white-winged Gull is an annual visitor to the north of Scotland, but southwards it becomes scarcer, and it is only in very severe weather that it visits the south of England. Its breeding range is circumpolar, its nearest breeding-place to our shores being in Iceland.

The mantle and wings are pearl-grey, with white tips to the secondaries and outermost webs of the quills. Orbital ring vermilion. Legs pink. Immature birds are whitish uniformly and thickly mottled with ash grey. Length 29 in.; wing 18 in.

THE ICELAND GULL
Larus leucopterus, Faber

This species is very closely allied in plumage and habits to the preceding. It is a winter visitor to the shores of Scotland, only coming south in severe weather. It breeds on Jan Mayen Islands and Greenland, and is only a winter visitor to the island whose name it bears.
