BRUNNICH’S GUILLEMOT.
This Guillemot, the Uria bruennichi of Sabine and most modern writers, is a very rare visitor to the British Islands, its home being in the Arctic regions, from Greenland possibly to the Liakoff Islands, off the coasts of northern Siberia. It deserves a passing notice, for it is possible that it occurs in British waters more frequently than is generally supposed. It is a perceptibly stouter bird than the Common Guillemot, and has the base of the upper mandible pale gray. In its habits and economy it is not known to differ in any special manner from the better known species, of which it is the Arctic form.
BLACK GUILLEMOT.
This species, the Dovekey, or Greenland Dove, of northern mariners, the Tysty of the Shetlanders, and the Uria grylle of naturalists, is by far the most local of the Auks that are indigenous to the British Islands. During the breeding season it is only known to frequent one English locality, the Isle of Man; but in Scotland it is pretty generally distributed along the western and northern coasts, including St. Kilda, the Orkneys, and the Shetlands. Its chief resorts in Ireland are on the north and west coasts. The difference between the summer and winter plumage of this little bird is most extraordinary. In spring it assumes a rich black dress, glossed with green, except a patch of white on the wings; in winter it is uniformly mottled black and white; the legs and feet are bright coral red. With us the Black Guillemot is strictly marine in its haunts, but in Spitzbergen it was found breeding more than a mile inland—a habit very different from any it displays with us. In its actions it very closely resembles its larger allies. Like them it is an expert diver—I have seen it dive repeatedly at the flash of a gun, and thus escape the shot. It is, on the whole, a more trustful bird, often permitting a near approach, and frequently remaining on the surface until the boat is about to pass over it, when it will dive and reappear quite unconcernedly a short distance away out of danger. This Guillemot often feeds quite close in shore. At St. Kilda I used to see parties of this species every evening, fishing under the cliffs; but, on the other hand, I have often met with them searching for food many miles from land. The Black Guillemot is nothing near so gregarious as the Common Guillemot, nor does it appear to wander so far from its breeding places to feed. It is partially nocturnal in its habits in summer, feeding well into the dusk, and during winter seldom comes upon the land, sleeping out at sea. Although capable of flying swiftly, it always prefers to escape danger by diving; it swims lightly, usually sitting high in the water, but it has the power of sinking itself more than half below the surface when apparently alarmed. Black Guillemots may often be seen in strings, flying to and from a distant feeding place, hurrying along close to the water, their short wings beating rapidly, and rendered very conspicuous by the broad white bar. The food of this Guillemot is largely composed of the fry of the herring and the coal-fish, but other small fishes are eaten, as are crustaceans, and various marine insects. I have never heard the Black Guillemot utter a sound beyond a low grunting; but its note has been described as a whining sound, that of the young birds being more shrill. In chasing its finny prey under the water the Black Guillemot displays astonishing powers, darting to and fro, aided by its wings and feet. During winter these birds wander southwards, and then they may sometimes be seen off our more frequented coasts.
The Black Guillemot retires to its breeding-stations in May. These are situated, in our islands, on rocky headlands and islands, and on ocean cliffs. Here its colonies are never very large, and often much scattered. It very probably pairs for life, and resorts often to one particular spot year after year. The bird deposits its eggs in a hole or cranny of the cliffs, occasionally in the clefts amongst fallen rocks at the foot of the precipice, or on rock-strewn downs sloping to the sea. It makes no nest, and the eggs rest upon the bare ground or rock. The Black Guillemot, and its allies, are remarkable for the fact that their eggs are two or three in number; in all other members of the Alcidæ the eggs never exceed one. This peculiarity has induced some systematists to restrict the genus Uria to the Black Guillemots alone. The Black Guillemot lays two eggs, much smaller than, and not so pear-shaped as, those of the Common Guillemot, cream, buff, or pale green in ground colour, blotched and spotted with rich dark brown, paler brown, and gray. The young chicks are said not to repair to the sea at so early an age as those of the preceding birds; and to be soon deserted by their parents after doing so, congregating in flocks by themselves.
RAZORBILL.
This bird, the Alca torda of Linnæus and ornithologists generally, is widely confused with the Common Guillemot, and many local names refer indiscriminately to each—such as Murre, Marrot, and Diver. It is readily distinguished from the Guillemots by its much deeper bill, crossed by a white line at its centre, and by a narrow yet very conspicuous white stripe, extending from the base of the bill to the eye. Otherwise, the Razorbill closely resembles the Guillemot in appearance, both in its summer and winter plumage. It is widely distributed round the British coasts, breeding in most situations where the cliffs are sufficiently suitable, but is much less abundant in the south, and is nowhere, perhaps, so numerous as the Guillemot. During the non-breeding season it becomes more generally scattered, and may then be met with, although ever sparingly, in the seas round most parts of the British coastline. Its actions in the water are almost precisely the same as those of the Guillemot. Like that bird it may be seen swimming to and fro, sitting highly and lightly on the water, often permitting a very close approach, especially in districts where it is not much harassed by the shooter. It dives with the same marvellous celerity as the Guillemot, pursuing its prey through the water, often at a considerable depth, as readily as the swallows chase an insect through the air. It is a very pretty sight to watch the Razorbill in quest of food. This may often be done from the summits of the cliffs, but certainly to better advantage from a boat, in which the birds can be more closely approached, and consequently better observed. A Razorbill in the water is a remarkably striking, if not an actually pretty bird. He sits so lightly, riding buoyantly as a cork on the swell, turning his head from side to side as the boat approaches, swimming rapidly before it, and often nonchalantly dipping his head into the water and throwing a shower over his upper plumage. The boat comes too near at last, and the bird, with a scarcely audible or perceptible splash, disappears into the water. Several moments afterwards he rises again to the right or left, ahead or astern, and the salt spray rolls off his plumage glinting like diamonds in the sun. Should fish be plentiful the birds are diving and rising again incessantly, the time of absence depending upon the depth descended or the length of the chase. The Razorbill ever seems to use its wings with reluctance on these occasions, always keeping out of harm’s way by diving or swimming. It is capable of rapid flight though, and may often be seen in strings or skeins, hastening along just above the waves to or from a favourite fishing place. The Razorbill is gregarious enough during summer, but in winter it is most frequently seen in small parties, or often alone. It also goes some distance from land, where, should a gale overtake it, great numbers often perish, as their dead bodies washed up on the coast sadly testify. The food of the Razorbill is largely composed of fry, especially of the herring, but many other small fishes are captured, together with crustaceans and other small marine creatures. The bird, so far as my experience extends, never seeks its food upon the shore, and obtains most, if not all, of it by diving. The Razorbill is a remarkably silent bird; the only sound I have ever heard it utter has been a low grunting. This note is uttered both in summer and winter, on the rocks as well as on the sea.
In May the Razorbill gives up its roaming, nomad life upon the sea, and collects in numbers at the old-accustomed breeding-places. These are situated on the ocean cliffs, such as contain plenty of nooks and crannies being preferred to those of a more wall-like character. It is possibly due to this that the Razorbill’s colonies are never so crowded as those of the Guillemot, and that the birds are more scattered along the coastline. There can be little doubt that the Razorbill pairs for life. As a proof of this I have known a Puffin burrow resorted to yearly, whilst eggs possessing certain peculiarities of form and colour have repeatedly been taken from one nook in the cliffs, years and years in succession. Like the Guillemot the Razorbill makes no nest, but lays its single egg in a crevice or hole in the cliffs, or far under stacks of rock, poised one upon another, where to reach it is an utter impossibility. Like most birds that breed in such situations, the Razorbill is much more loth to quit its egg than the Guillemot, often remaining upon it until captured. When alarmed by man the birds may be heard scrambling amongst the crevices, and uttering their grunting cries of remonstrance.
The single egg of the Razorbill, though not displaying a tithe of the variety observed in that of the Guillemot, is a remarkably handsome object. The ground colour varies through every tint between white and reddish-brown, and the handsome large blotches and spots are dark liver-brown, reddish-brown, gray, or grayish-brown. No shade of green or blue is ever apparent upon them externally, but the shells, when held up to the light, have the interior of a clear pea-green tint—a character which readily serves to distinguish them from such eggs of the Guillemot that resemble them in external colour. If the first egg be taken the bird will lay another, and this process may be repeated several times, but on no occasion is more than one chick reared in the season. It is said that the young of this species remain upon the cliffs for a much longer period than the chicks of the Guillemot, and that they eventually fly or flutter down to the sea, never revisiting the rocks. The parent will sometimes dive with its offspring, just as the Little Grebe will do.
LITTLE AUK.
This species, the Rotche of Arctic navigators, and the Mergulus alle of ornithology, is but an irregular visitor to British seas during autumn and winter, and as it seldom comes near the land under ordinary circumstances, is not a very familiar bird to the seaside observer. Exceptionally severe weather not unfrequently drives this little bird far inland. In its general colouration the Little Auk closely resembles the Razorbill, but it is less than half the size, and has a considerable amount of white on the wings. This curious little species congregates in incredible numbers at certain spots in the Arctic regions, to breed. Beechey, at the beginning of the present century, records that he has seen nearly four millions of these birds on the wing at one time. Colonies of the Little Auk are known in Nova Zembla, Franz-Josef Land (?), Spitzbergen, Grimsey Island (to the north of Iceland), and the coasts of Greenland. Like all its larger allies, the Little Auk is thoroughly pelagic in its habits, apparently only visiting the land to breed, living on the sea for the remainder of the year. It is well adapted for its lengthened sojourn upon the waters. It swims well and buoyantly, sitting rather low, flies rapidly when inclined, dives with as much ease as a fish, and sleeps quite safely and comfortably upon the waves. Voyagers in the Arctic regions have met with flocks of Little Auks at most times of the year, often far from land, and occasionally crowding upon the masses of floating ice. All observers agree in describing it as a somewhat noisy bird, and its specific name of alle is said to resemble its ordinary note. There is scarcely a winter that the Little Auk is not obtained in varying numbers off the British coasts, more frequently, of course, in the northern districts, but under ordinary circumstances it keeps too far off the land to be observed, and occurs most plentifully during periods of continued storm. Where the uncounted millions of Little Auks winter, that are known to breed in the Arctic regions, washed by the Atlantic, is still an unsolved problem. The few that are observed are as nothing in comparison with the numbers that crowd at certain spots during summer. Perhaps it is because the area of distribution is so wide in winter, and, comparatively speaking, so restricted during summer. The food of the Little Auk consists largely of minute crustaceans, and possibly of small fish. The bird is said to resort to the vicinity of fishing fleets, to pick up the refuse thrown overboard.
In May, the Little Auk resorts to the land to breed. It is eminently gregarious, and some of its colonies consist of an almost incredible number of birds. Curiously enough, its breeding places are not always by the sea, some of them being situated a considerable distance from the coast. Sloping rock-covered banks at the foot of the cliffs, seem to be preferred to the cliff themselves. A favourite situation is on the sloping ground below a range of cliffs, where the surface is covered with stones and rock fragments that have, during succeeding ages, crumbled from the precipices towering above. Here, in cavities, worn by wind and storm, beneath large stones and rock fragments, or in various hollows and holes under the fallen débris, the Little Auk deposits its single pale greenish-blue egg, out of reach of the Arctic foxes that prowl about the colony in quest of prey. The actions of the Little Auk at its nesting colony, seem to be very similar to those of the Puffin when breeding on slopes, as, for instance, on the island of Doon, one of the St. Kilda group.
PUFFIN.
Of all the Auks the present species, the Alca arctica of Linnæus, and the Fratercula arctica of modern ornithologists, is not only the best known, but the most readily distinguished. The Puffin cannot readily be mistaken for any other bird along the coast, his big brightly coloured beak and comical facial expression, being never failing marks of his identity. In the colour of its plumage the Puffin somewhat closely resembles the Guillemot or the Little Auk, only the throat and the sides of the head are white. The most striking feature in the Puffin is its beak—a deep, laterally flattened, coulter-shaped organ, banded with blue, yellow, and red, singularly grooved and embossed with horny excrescences, although these latter are only assumed for the pairing season, and are cast again when the breeding period is over! Unlike most birds, therefore, the Puffin displays his wedding ornaments on his beak! And this singular peculiarity appears to be common to various other species, more distantly allied, yet undoubtedly of close affinity with the English Puffin. Many local names have been applied to the Puffin in consequence of its singular bill. Bottlenose, Coulterneb, and Sea Parrot, may be mentioned as the most commonly used. Like most, if not all, members of the Auk family, the Puffin is not seen much near the land after the breeding season has passed. Indeed, it is very doubtful whether the bird ever voluntarily seeks the coast after it leaves it in early autumn with its young; continued gales and storms will occasionally drive a bird even far inland, whilst rough weather often causes it to perish at sea, its remains being sometimes washed up in quantities. Its actions on the water are almost precisely the same as those of the Guillemot and Razorbill. It is an adept swimmer, a marvellous diver; it flies well and strongly, especially during the summer, where I have seen it in swarms, drifting round and round the highest peaks of its island haunt on apparently never-tiring-wing. At the summit of the cliffs its powers of flight may often be witnessed to perfection. At St. Kilda, I have watched it gracefully poising itself in the air, its narrow wings beating rapidly, and its two orange-coloured legs spread out behind acting as a rudder. Of all the Auk tribe, so far as my experience goes, the Puffin flies the most. The Puffin feeds principally upon small fish, especially sprats and the fry of larger fishes; it also eats crustaceans, and various marine insects. It dives often to a great depth, and is remarkably active beneath the surface; when on the water it generally tries to escape from danger by diving. Sometimes the Puffin may be seen close ashore during winter, but never in any abundance.
The Puffin becomes by far the most interesting at its breeding places. The regularity of its appearance at these has often been remarked. In many localities it not only arrives punctually on a certain day, but retires from them in autumn with its young almost as regularly! In some places Puffins arrive on the land to breed as early as March; in others, not before April; in others, yet again, not before the beginning of May. With the exception of the south and east coasts of England—where it is only sparingly and locally distributed—the Puffin, from Flamborough northwards, is widely and generally dispersed. In some places its numbers are almost incredible, as for instance, at Lundy Island, the Farne Islands, on some of the Hebrides, and St. Kilda. There is a very interesting colony of Puffins established amongst the walls of the ancient fortress on the Bass Rock, but so far as my experience goes the colony on St. Kilda stands unrivalled, and, at a very moderate computation, must consist of many millions of birds! The Puffin most probably pairs for life, and returns time out of mind to certain familiar spots to rear its offspring. In most places the bird makes its scanty nest in a burrow which it excavates itself, but in some localities rabbit holes are frequently made use of. In some localities, however, the bird makes a nest in a crevice of the cliffs or beneath heaps of rocks. By the end of April both birds are engaged in scraping out this burrow, if circumstances demand it, which often extends for several yards in the loamy soil, sometimes sloping downwards, sometimes tortuous, sometimes nearly straight. At the end, or elsewhere in some cases, the slight nest of dry grass and a few feathers is formed. Occasionally several pairs occupy one burrow, each pair enlarging a portion of it for their own requirements into a kind of chamber; whilst many of the burrows have several openings, and are evidently the work of successive years. In this rude nest the hen Puffin lays a single egg, dull white, sometimes tinged with blue or gray, and obscurely spotted with pale brown and gray. Contact with the earth in the burrow and with the wet feet of the sitting bird, soon discolours this egg, and renders it almost like a ball of peat in appearance. When disturbed at their breeding places, such Puffins as may chance to be outside the holes soon fly off to the sea, and join the hosts of birds that swarm in the water near every breeding station. Those in the burrows, however, remain, allowing themselves to be dragged out without making any attempt to escape. Great caution and gloves are recommended, for the Puffin resents intrusion and bites fiercely, being able to inflict a nasty cut with its powerful beak and sharp claws.
I still retain the most vivid impressions on my visit to the grand colony of Puffins on Doon, one of the St. Kilda group. Every available place is honeycombed with their holes; the ground cannot afford accommodation for all, and numbers of birds have to seek nesting places under the masses of rock lying on the grass-covered hillsides, or in the crannies of the cliffs at the summit of the island. As soon as we had fairly got ashore, and begun to walk up the slopes, the Puffins, in a dense whirling bewildering host, swept downwards to the sea, or rose high in air to circle above our heads, in the direst alarm. It seemed as if the whole face of the island were slipping away from under me, just like flakes of shale down a quarry side! Not a single bird, so far as I could ascertain, uttered a note, but the whirring noise of the millions of rapidly beating wings sounded like the distant rush of wind! But even Doon does not harbour so many Puffins as find a home on the face of the mighty cliff Connacher; and when we fired a gun and disturbed them from this noble precipice, it seemed as though the face of the entire cliff was falling outwards into the Atlantic, the enormous cloud of birds overpowering one with its magnificence! As soon as the young are reared the land is deserted, and the wandering pelagic life resumed.
In connection with this species mention may be made of its former repute as an article of food. Old records inform us that the young Puffins were regularly gathered by the owners of the breeding-places, and were salted down for future food. Gesner and Caius assert that the Puffin was allowed to be eaten during Lent, probably because, in the words of Carew, of its coming nearest to fish in taste. More than two hundred years ago Ligon, in his History of Barbadoes, complains of the ill taste of Puffins which he had received from the Scilly Islands (once a great centre of exportation of these birds), and asserts that this kind of food is only for servants. The taste for salted and dried Puffin, however, still lingers in the land; for at St. Kilda vast numbers are caught, and so preserved by the natives for food. Dried Puffin, perhaps a twelvemonth old, is one of the few delicacies of the island; whilst the feathers help materially to pay the rent!

The birds included in the present chapter belong to three well-defined families. None of them are so completely pelagic as the Auks, and yet, according to season, many of them are interesting features in the bird-life of the coast. Unfortunately for the summer visitor to the seaside, the Divers will be absent. They are birds that resort chiefly to inland districts to rear their young, or are only known as winter visitors to the British Coasts. The Divers form a small but well-marked family known as Colymbidæ, consisting of a single genus Colymbus, into which are grouped the four species that are now known to science. The Divers are allied to the Auks on the one hand, to the Grebes on the other, although systematists are not yet agreed upon the degree of their relationship. United, these three families form Dr. Sclater’s order Pygopodes. In every way the Divers are remarkably well fitted for an aquatic life. Their strong tarsi are laterally compressed, a form best suited for cleaving the water, the hind toe is well developed, and on the same plane as the rest, the feet are webbed, the bill is long, straight, spear-shaped and conical, admirably adapted for seizing the finny prey, the wings are comparatively short, yet capable of bearing the bird at great speed, the tail is short and fairly developed. The Divers in nuptial plumage are remarkably handsome birds, the neck being striped or richly marked, and the upper plumage beautifully spotted or adorned with white bars. They are all more or less gregarious birds during winter, and well marked social tendencies are displayed in some species during the breeding season. Their migrations, if comparatively short, are pronounced and regular. The young are hatched covered with down, able to swim with ease almost immediately. Adults moult in autumn, and assume their nuptial plumage in winter—a period doubtless when they pair—the winter plumage thus being carried for a short time. Young Divers carry their first plumage through the winter until the following spring (not moulting in December with their parents), when they assume their summer plumage, but the nuptial ornaments are not so brilliant in colour as in adults. Whether the vernal change in colour is effected without moulting, as in the Auks and some of the Limicolæ, appears not to have yet been ascertained. All the species of Divers are visitors to the British Islands, but only two breed in them, and one is an exceptionally irregular straggler. This is the largest of them all, the White-billed Diver, Colymbus adamsi, and a species apparently circumpolar in its distribution. The Divers are all birds of the north-temperate or Arctic regions, during summer; in winter their range is much more extended, almost reaching to the northern tropics. With this brief résumé of their more salient characteristics, we will now proceed to a more detailed examination of their economy.
GREAT NORTHERN DIVER.
This species, the Colymbus glacialis of Linnæus and of ornithologists generally, is, in its breeding plumage, one of the handsomest of British birds. Its chief characteristics are its large size—about that of a Goose—black head and neck, double semi-collars of white and black vertical stripes, and black upper parts, marked with white spots of varying size, and arranged in a series of belts. Whether it actually breeds within our limits has not yet been absolutely determined, although evidence is forthcoming that seems to point to the fact. Unfortunately for the seaside student of bird life, the Great Northern Diver is only known as a winter visitor. At that season, however, it may be met with pretty frequently off the British coasts, the young birds especially venturing into our bays and creeks and estuaries, older individuals, as a rule, keeping further out to sea. Adult birds are, however, often observed near the coasts of South Devonshire and Cornwall. I have known them linger in the waters near here until the summer has been well advanced. Young birds of this species, in the brown and white dress characteristic of immaturity, may often be seen quietly fishing under the cliffs, notably in Tor Bay. One very remarkable thing about this Diver is its singular habit of immersing the body to such a depth that the back is quite under water. It often so sinks itself when menaced by danger, and then, almost out of sight, swims away with great speed. If pursuit is still continued all but the neck is sunk below the surface, and finally, if hotly pressed, the bird will disappear entirely, and swim along under water at a speed absolutely astonishing, Gätke records that this Diver, when chased by a boat under these circumstances, will dive and allow the boat to pass over it, rising again in the rear of it, a habit which my own observations of the bird completely confirm. How this act of immersion, without apparent effort, is accomplished remains a mystery, and offers a problem in animal mechanics by no means easy of solution.
The Great Northern Diver is rarely seen on land, perhaps never except during the breeding season. Its movements on shore are ungainly in the extreme, the legs being placed so far back that the bird can only push itself along in a crawling sort of a way; it is equally rarely seen in the air, and apparently only uses its wings to fly when performing its annual migrations. How the species still retains the function of flight at all seems almost a mystery, but perhaps the constant use of the wings in the water keeps them to a standard of efficiency. This Diver is one of the least gregarious, and save on passage is rarely met with in numbers greater than a pair. It seems to be the rule for odd pairs to take up their residence in certain spots during the breeding season; after that period the bird is usually met with solitary, and the young individuals, unlike so many others that evince strong gregarious propensities, for the most part wander about alone. This Diver, like most big birds, is shy and wary, although I have repeatedly watched it from the cliffs in Tor Bay evincing little concern at my presence. As may be gathered from the foregoing remarks the Great Northern Diver is a proficient in the art of diving, and is said to be able to remain as long as eight minutes beneath the surface—a period of time which seems incredible. The depth to which it sometimes descends is also enormous—it has been captured in a net thirty fathoms from the surface. The food of this Diver is almost, if not absolutely, composed of fish. During the non-breeding season Divers are not particularly noisy birds, but at their nesting-places the cries they utter are both loud and startling, described by some listeners as similar to the screams of tortured children; as shrieks of maddened laughter, or as weird and melancholy howls by others.
It is a somewhat remarkable fact that the Great Northern Diver breeds nowhere in Europe, except on Iceland. It is an American species, and nests from Greenland westwards to Alaska, south of the Arctic circle to the more northern of the United States. It reaches its breeding-grounds in pairs towards the end of May, as soon as the northern waters are free from ice. Its favourite nesting places are secluded tarns and lakes, and an island is always selected if possible, doubtless from motives of security. The nest—always made upon the ground—varies a good deal in size, according to the local requirements. On wet marshy ground it is large, and composed of a heap of half rotten sedges, rushes, reeds, and such like vegetation, lined with dry bits of broken reed and withered grass. On drier and barer situations it is little more than a hollow in the sand or hard ground, with, perhaps, a few bits of dry grass for lining. The birds are very alert and watchful whilst nesting, as if fully conscious of their comparative difficulty in escaping from danger on the land. One bird is generally on the look out whilst the other sits, and at the least danger the alarm is given, and the incubating partner shuffles off in a floundering way to the water. A path is soon thus worn from the nest to the lake. The eggs are almost invariably two, elongated, and varying in ground colour from russet-brown to olive-brown, spotted sparingly with blackish-brown and paler brown. When the young are sufficiently matured, the inland haunts are deserted, and the nomad wandering life upon the sea resumed.
BLACK-THROATED DIVER.
The present species of Diver (much smaller than the preceding), the Colymbus arcticus of Linnæus and most other writers, is the rarest of the three that visit the British Islands regularly, and perhaps we might also say the most beautiful in nuptial dress. All its showy colours and patterns, however, are on the head, neck, and upper parts, the under surface being white. The head is gray, the throat patch black, above which is a semi-collar of white striped vertically with black; the sides of the neck are also striped with black and white; whilst the black upper parts of the body are conspicuously marked with a regular series of nearly square white spots, becoming oval in shape on the wing coverts: the bill is black, the irides crimson. After the autumn moult all this finery is lost, and the upper parts become a nearly uniform blackish-brown. This Diver breeds sparingly in various parts of the Hebrides and the Highlands, from Argyll to Caithness; elsewhere it is only known as a winter visitor. In many of its habits it closely resembles the preceding species. It is exclusively aquatic, only seeking the land during the breeding season, but is, perhaps, not quite so oceanic as that bird in the winter, when it not unfrequently haunts inland waters. It dives with equal skill, flies with the same powerful rapidity, and utters during the nesting season very similar unearthly cries. Fish form the chief food of this Diver, but it is said also to capture frogs. Most of the examples of this Diver that are seen close in-shore (on our eastern and southern coasts principally) during winter are immature, the older birds as a rule keeping further out to sea. The Black-throated Diver indulges in the same peculiar habit of gradually sinking its body in the sea when alarmed, and will frequently seek to escape pursuit by diving outright, and swimming under water for a considerable distance.
The Black-throated Divers that breed with us, retire to their inland haunts in May. Its favourite nesting places are on islands in moorland lochs, pools, and tarns. It displays few social tendencies at this season, although several pairs not unfrequently nest within a comparatively small area of exceptionally suitable country, each, nevertheless, keeping to its own particular haunt. This Diver may also pair for life, seeing that it evinces considerable attachment to certain favourite nesting places. The nest is always made upon the ground, and seldom very far from the water, to which the frightened bird can retire readily. An island covered with short herbage is always preferred in Scotland, but in some places the bare shingly beach is selected. This nest, often of the slightest construction, is made of stalks of plants, roots, and all kinds of drifted vegetable fragments, lined with grass. Sometimes no nest whatever is made. The two eggs are narrow and elongated, olive- or rufous-brown, sparingly spotted and speckled with blackish-brown and paler brown. The sitting bird is ever on the alert to slip off into the water at the first alarm; and sometimes both birds will fly round and round in anxiety for the fate of their treasured eggs. A movement seawards is soon taken when the young are sufficiently matured. This Diver has a wide geographical range outside our limits, extending across Europe and Asia to Japan and North-west America, perhaps as far as Hudson Bay. American authorities, however, insist upon the specific distinctness of most of the Black-throated Divers found in Alaska, and have named this form C. pacificus.
RED-THROATED DIVER.
Smallest of the British Divers, the present species, the Colymbus septentrionalis of Linnæus and modern authorities, is also the best known and the most widely distributed. It is also the least showy in nuptial dress. In this plumage the throat is marked with an elongated patch of chestnut; the head, and sides of the neck are ash-brown, the latter striped with black and white, the general colour of the upper plumage blackish-brown, sparingly spotted with white, and the under parts are white. The plumage, as in all the Divers, is remarkably dense and compact, adapted in every way to the aquatic habits of the bird. The Red-throated Diver is a fairly frequent visitor, during autumn and winter, off the English coasts, often entering bays and the mouths of wide rivers. In summer, however, it becomes much more local, retiring then to haunts in Scotland, especially in the Hebrides and along the wild and little populated western districts, from the Clyde northwards to the Shetlands. Outside our limits, this Diver has a very wide distribution, occupying in summer the Arctic and north temperate regions of Europe, Asia, and America; in winter migrating southwards for a thousand miles or more. The Red-throated Diver is certainly the most gregarious species, and in winter may not unfrequently be seen in gatherings of varying size. In connection with this trait, mention may be made of the extraordinary numbers of this bird that, on the 2nd and 3rd of December 1879, passed Heligoland. The movement was not strictly a migratory one, but a grand flight of storm-driven, frozen-out birds, seeking more congenial haunts. Gätke tells us that during this visitation, there was about thirteen degrees of frost, an easterly wind, and a snowstorm in the evening. The Divers were by no means alone in their distress, for hundreds of thousands of Ducks, Geese, and Swans, Curlews, Dunlins, and Oyster-catchers, passed from east to west. From early morning until noon, on both days in succession, the Divers were seen in one incessant stream, travelling north-east, in numbers estimated almost by the million! Well may Gätke have wondered whence such vast multitudes came, and whither they were going, and what was the initial cause of such gregarious instincts, never manifested in this Diver under any ordinary circumstances.
The Red-throated Diver is a master at the art of diving, and is often seen slowly to sink its body under water when alarmed. It also flies with great strength and speed, and is said to show more preference for flying than either of its congeners. The food of this Diver is chiefly composed of fish. Its ordinary note is a harsh ak or hark; but at the nesting places the same wild unearthly cries are uttered that are equally characteristic of the other species. These cries are said to foretell rain or rough weather, and have caused the bird to be called “Rain Goose” in many Highland districts. The Red-throated Diver, however agile and graceful it may be in the water or even in the air, is a clumsy object on the land, incapable of walking upright, owing to the backward position of its legs, and compelled to shuffle along with its breast touching the surface. In winter these Divers are by no means shy, and I have many times watched them pursuing their fishing operations, from my station on the cliffs.
In May, the Red-throated Diver retires to its breeding stations—the wild romantic lochs and pools so characteristic a feature of the Highlands and the Hebrides. Solitary pairs generally scatter themselves over a district, resenting intrusion, and keeping to their own particular haunt. This Diver probably pairs for life, returning each successive season to a certain spot to nest. An island is usually selected for the nest, which is invariably made upon the ground, and consists generally of little more than a hollow, into which is collected a few bits of withered vegetation. As may be expected, this nest is seldom made far from the water, so that at the least alarm the sitting bird can slip off and shuffle into the water at once. The two narrow elongated eggs are olive- or buffish-brown, spotted and speckled with blackish-brown and paler brown.
GREBES.
In many respects Grebes are remarkable birds. They form so well defined a group that no other known bird can possibly be confused with them, their characteristics being absolutely unique among the class Aves. The most noticeable external features of a Grebe are its relatively short body, laterally compressed tarsi, lobed feet, rudimentary and functionless tail, and dense compact plumage of a peculiar silky texture. The twenty or so species of Grebes are grouped into a single family, called Podicipedidæ, of which the genus Podiceps (or more correctly Podicipes) contains the greater number. The Grebes are almost cosmopolitan. Five well-marked species are found in Europe, all of which, being visitants or regular residents, are included in the British avifauna. In the colours of their plumage the Grebes are not very remarkable, with the exception of the crests or tippets assumed by some species during the nuptial period: plain browns predominate on the upper surface; the underparts are almost always glossy white. The Grebes fly well; dive with great dexterity, but their movements on the ground are not graceful. The young are hatched covered with close down, and able to swim at once. The Grebes have a complete moult in autumn, and assume their nuptial ornaments in spring. The quill feathers are moulted so rapidly that for some little time the birds are unable to fly, as is the case with the Geese and some others.
It is only during the winter months that the Grebes become pelagic or marine in their habits, and even some species are much less addicted to a sea life than others. We will now proceed briefly to glance at the British species.
GREAT CRESTED GREBE.
This, the largest species, the Podicipes cristatus of naturalists, is chiefly an inland bird, but resorts to the sea when fresh waters are frozen. I have sometimes met with half a dozen together in a quiet bay, under these circumstances, and very graceful interesting birds they are. They rarely come upon the land at these times, swimming about and diving from time to time in quest of food. Like the Divers, they sometimes sink the body very low in the water, but under ordinary conditions sit rather high, with the long neck held well up, the head turned at intervals in all directions as if on the look out for enemies. They always prefer to dive when pursued; and as this species more especially is in great demand by plumasiers, and subject to much persecution, it is wary and shy in extreme. The food of this Grebe whilst on the sea is composed largely of fish, but inland the bird’s tastes are more omnivorous. Sometimes many of its own feathers are found in its stomach, mixed with the food, but as yet ornithologists have been unable to assign any plausible explanation of the fact. In Spring, the adults assume two very conspicuous crests or horns of a dark brown colour, and a tippet or ruff of bright bay, shading into nearly black on the margin. The birds now retire inland to meres and lakes, where the shallows are full of reeds, sedges, rushes, and other aquatic vegetation, and here, at some distance from the shore, a large floating nest is made, composed of dead and decaying vegetation. As the bird is sometimes gregarious several nests may often be found within a small area—huge floating rafts moored to the reeds, or built up from the bottom of the shallow water. In a shallow depression at the top four or five eggs are laid, elliptical in shape, chalky in texture, and white, until contact with the bird’s wet feet and the wet nest covers them with stains. Several mock nests are often made in the vicinity of the one containing the eggs, probably destined as resting places for the future young. The sitting bird very dexterously covers its eggs with weed when alarmed, previous to slipping off the nest into the water. The note of this Grebe is a loud kak.
RED-NECKED GREBE.
This Grebe, the Podicipes griseigena of Boddaert, and the P. rubricollis of most modern naturalists, is a fairly common winter visitor to the seas off our eastern and southern coasts, from the Orkneys to Cornwall. The range of the Red-necked Grebe outside our limits is a wide one, and embraces during summer the sub-Arctic portions of Europe, Asia, and America, becoming much more southerly in winter. During winter this Grebe may be met with close inshore, yet it seldom or never visits the land, living exclusively on the sea. Its habits at this season do not differ in any marked degree from those of its congeners. It may be seen swimming to and fro, sometimes just outside the fringe of rough surf, diving from time to time in quest of its food, which at this season is composed of fish principally. The nuptial ornaments of this Grebe are not so conspicuous as those of the preceding species, the dark crests are shorter, the tippet is scarcely perceptible, and the lower neck and upper breast are rich chestnut. In winter plumage this Grebe is best distinguished by its large size—next in this respect to the Great Crested Grebe—and by the absence of the white streak over the eye, which characterises that bird then. In April the Red-necked Grebe returns to its accustomed inland summer haunts to breed. These are reed and rush-fringed lakes and ponds. Here in the shallows a floating nest of rotten vegetation is formed, smaller than that of the preceding species, but otherwise closely resembling it. Many pairs may be found breeding close together—in colonies, so to speak. The four or five elliptical shaped eggs are laid in May or June, dirty white in colour, chalky in texture. The same habit of covering the eggs with weeds, previous to leaving them, may also be noted.
BLACK-NECKED GREBE.
This bird, the Podicipes nigricollis of systematists, is so rarely met with in the British area, that it scarcely requires more than a passing allusion. Examples occasionally occur on our eastern and southern coasts especially, but the bird is too rare to form any feature in the ornithology of the British seaboard. It may be readily distinguished from the other European Grebes by its decidedly up-curved bill, and by the large amount of white on the primaries and secondaries. In the nuptial plumage the head and neck are black. In its habits generally it differs little from the other species.
SCLAVONIAN GREBE.
Along the eastern coasts of England, and round most of the Scottish littoral, as well as off Ireland, this species, the Podicipes cornutus of most naturalists, is of tolerably frequent occurrence during winter. It requires all the skill of an expert ornithologist to distinguish this Grebe in winter plumage, so closely does it resemble the Red-necked species. It is a shorter winged bird, and has the three outermost secondaries dusky brown, instead of white, as in that bird, whilst the previous species is always distinguishable by its up-curved bill. There is nothing in the habits of this Grebe to call for special remark: it keeps exclusively to the water, dives to escape danger and to capture prey, and swims beneath the surface as adroitly as a frog. The Sclavonian Grebe is a wide ranging species, inhabiting during summer the Arctic and sub-Arctic regions of Europe, Asia, and America, retiring southwards in winter. This Grebe is exceptionally remarkable for its nuptial ornaments, but which, as usual, are confined to the head and upper neck. Two chestnut or bay-coloured crests start backwards over the eyes, whilst the tippet is black. This ornament, when extended to its utmost, looks very beautiful, and gives the head an appearance of being surrounded by a glittering aureole. This Grebe is a late breeder, the eggs not being laid before June. It retires to fresh-water pools for the purpose of nesting, and resembles the other species closely in its habits at this season, making a slovenly floating nest, and laying four or five dull white eggs.
LITTLE GREBE.
This species is the smallest of the European Grebes, and certainly by far the best known member of the family found in the British Islands. It is rather remarkable that the Little Grebe was unknown as a distinct species to Linnæus. It was known to Brisson as Colymbus minor, and to most modern ornithologists as Podicipes minor, although some few writers speak of this bird as P. fluviatilis. Outside the British Islands it has a very wide distribution in Europe, Asia, and Africa, but the Little Grebe of America is a distinct species. The Little Grebe is found more or less frequently on the coast during winter, driven thereto when frosts seal up its inland haunts. On the coast this bird is more partial to the brackish back-waters, dykes, and estuaries, than to the open sea. The food of this bird consists not only of fish, but small crustaceans and molluscs, aquatic insects, young frogs, and various vegetable fragments. Its habits are very similar to those of the other Grebes; its swimming and diving powers are wonderful; its flight on occasion is rapid and strong, whilst its note is a shrill but not very loud weet. In its nesting economy the Little Grebe closely resembles its congeners. It quits the coast in spring, resorting to inland pools, often of very small size, making its usually floating or water-surrounded nest amongst the vegetation fringing the shallows, on which it deposits five or six eggs, dull white in colour. The parents often dive with their young from the nest to carry them out of impending danger—a habit common to all species in this genus.
CORMORANTS.
The Grebes are so little in evidence to the seaside naturalist that an account of them seems more like a digression in our narrative, than a continuation of our observations concerning the bird life of the sea. We now, however, reach another pelagic group, consisting of birds that form an important and seldom absent feature in marine ornithology. And yet, so great is the adaptability of some species, the Cormorant is by no means exclusively confined to the sea, has many inland breeding stations, and repeatedly wanders from the coast to fresh waters, where an abundant supply of fish offers a solace to its great voracity. The Cormorants and the Gannet are members of the family Phalacrocoracidæ, although generically distinct from each other. Their principal external characteristics are the webbed feet, each toe, including the hind one, being connected by a membrane, the long and powerful wings, and the strong beak. The young birds in this family are hatched naked and blind, but soon become clothed with down. The first plumage differs considerably from that of maturity, and the latter is not rarely attained for several years. These birds have but one actual moult in the year, in autumn, but just previous to the pairing season in winter, crests in some species, and ornamental filaments and tufts in others, are assumed, but are lost by abrasion during the ensuing breeding period. Three members of this family are British, and breed abundantly within our limits. Cormorants and Gannets are widely dispersed species; the former are almost cosmopolitan, only being absent from the polar regions and Polynesia; the latter are most abundant in the tropics and the southern seas. A detailed account of the three British species will now be given.
CORMORANT.
From the autumn onwards to the following spring, there are few parts of the coast, indeed, where this bird, the Phalacrocorax carbo of ornithologists, may not be seen; whilst even in summer it is sufficiently widely dispersed to merit us classing it as common. It is, however, seldom seen off low-lying coasts, save after the breeding season, or except such individuals as have not yet reached maturity. There is but one other British species with which the Cormorant may be confused, and that is the Shag; but even then the difference in size is sufficiently great for the much larger Cormorant to be readily identified. Very black, very heavy, and very clumsy the Cormorant looks, as he rises in slow cumbersome flight from the sea, or unfolds his big, bronzed-green wings, and flutters into the air from a rock shelf, or sea-girdled pinnacle; but very soon one’s opinion of him undergoes a change, as, when once fairly on his way, he passes swiftly enough over the sea to a distant resting place, or after flying some distance, pitches down into the water. The colours of the Cormorant are not seen to best advantage at a distance. Certainly the prevailing colour is black, but this is richly loricated with green and purple tints, whilst most of the upper plumage of the body is a beautiful bronzy-brown, the feathers being margined with soft velvety-black, shot with green; the throat is white, as are also the sides of the head; whilst the bright yellow gape and bare portions of the throat form a pleasing contrast to the more sombre hues. As the breeding season approaches the Cormorant increases in beauty; large white patches of silky feathers spring out from the thighs, and the dark head and neck become covered by feathery filaments of white. Perhaps the Cormorant is most interesting when engaged searching for food. This bird obtains its food in various ways. Most frequently of all, it swims to and fro, diving with a headlong plunge at intervals; sometimes it swims with its body low in the water, and the head and neck below the surface peering about in quest of fish. Less frequently it takes up its station on a rock, or even on a tree, from which it flies from time to time, Kingfisher-like, to capture a fish near the surface; or occasionally it dives from such a situation, and pursues its finny food far down into the crystal depths. The Cormorant, however, never fishes like the Gannets and the Terns, by a headlong plunge from the sky. This bird may often be met with fishing in fresh-water some distance inland. Waterton records how it used to visit his lake at Walton Hall; but the habits of the bird on sea and shore shall exclusively claim our attention here. After a meal the Cormorant is very fond of resorting to a rock to rest, and to dry its plumage, standing perfectly motionless with its wings uplifted and outspread. Few, if any, birds can excel the Cormorant in diving: it vies with the very fish themselves, and seems as much at home beneath the surface of the water as in the air. The Cormorant when taken young is easily tamed, and from the earliest recorded times it has been trained to capture fish for its owner. To this day the Chinese and Japanese train Cormorants for this purpose. In England this sport was once a regal pleasure, the Master of the Cormorants finding a place in the Royal household. According to Professor Newton, the sport still lingers amongst a few. Willughby asserts that the trained Cormorant was carried hooded until cast off, but nowadays its bearer protects his eyes from a stroke from the bird’s beak, with a wire mask. A strap or a ring is fastened round the Cormorant’s neck, to prevent it swallowing its captures, just as we muzzle a ferret to prevent it lying up. All who have witnessed this novel way of fishing testify to the bird’s marvellous skill in catching fish after fish, until the gular pouch will hold no more, when the Cormorant is taken, and the fish removed. The food of this bird is composed almost entirely of fish. In winter Cormorants become even more gregarious, often associating in large flocks which wander far in quest of food. This bird is not so completely pelagic in its habits as the Auks, the Divers, and the Grebes. It generally retires to the caves and shelves of the cliffs to sleep, whilst stormy weather will drive it shorewards soon, where it will sit and mope on the rocks, or shelter in the quiet creeks, or under the lee of cliffs, as if waiting for the sea to subside, and allow of its labours being renewed.
As the Cormorant returns for years in succession to one particular spot to breed, there can be little doubt that it pairs for life. The birds begin to associate closely in pairs somewhat early in spring; but actual nesting duties do not commence for a little time after that event. In most places the Cormorant breeds in colonies, the size apparently varying according to the amount of accommodation. For the present purpose we need not describe in detail any of the inland nesting places of this species, beyond remarking that the bird often breeds in trees like Rooks, making a huge nest of sticks and twigs, lined with grass. Upon the coast the favourite breeding resorts of the Cormorant are ranges of lofty cliffs, and small low islands and reefs. The nest may thus either be on the ground—as at the Farne Islands, for instance—or on a ledge of the cliffs. When in the former situation it is generally composed of masses of seaweed, stalks of marine plants, and lined with green grass or other herbage. A Cormorant’s nesting place is by no means a pleasant one for persons whose olfactory nerves are sensitive, the smell from the decaying fish, and from the droppings of the birds, that literally whitewash the whole vicinity, being sickening in the extreme. Other sea fowl usually give these colonies a wide birth. The eggs are from three to six in number, of a delicate bluish-green—where the colour can be detected through the abundant coating of lime—small for the size of the bird, and long and oval in shape. When disturbed the sitting Cormorants make little demonstration, but fly out to sea at once. But one brood is reared in the season, and the eggs are deposited during April or May, in the British Islands. The Cormorant is a silent bird: the only note I have ever heard it utter has been a croaking one at the nest.
SHAG.
This species, the Pelecanus graculus of Linnæus and Latham, and the Phalacrocorax graculus of most modern writers, is readily distinguished from the Cormorant by its smaller size, more glossy appearance, and much greener general colouration. The Shag differs structurally from the Cormorant in possessing only twelve tail feathers, the latter bird having fourteen. The nuptial ornaments are also very different, for just previous to the pairing season, in early spring, a nodding plume or frontal crest of recurved feathers is assumed. The Shag is a much more marine bird than the Cormorant, and its appearance inland is exceptional. Of the two species the Shag is certainly the commonest and most widely dispersed, being met with off almost all parts of the British coasts, but preference is shown for such as are rocky, and where the ranges of cliffs are full of hollows and caves. Outside our islands the range of the Shag is restricted to the coasts of western Europe, and the Mediterranean basin. As a rule the Shag keeps well into the coast, seeking for its food in the somewhat deep water below the rocks, and retiring to some fissure or cave to sleep. Its habits in most respects are very similar to the larger species. It flies well and rapidly, if in a somewhat laboured manner, dives as skilfully as its ally, and often indulges in the habit of sitting on the rocks with wings extended, basking in the sun. It is equally gregarious during the non-breeding season, and it is no uncommon thing to see a hundred or more birds of this species sitting in solemn statuesque rows on some sea-encircled rock, gorged with fish and digesting their food. At these gatherings many birds may be noticed still fishing in the sea around, or flying up to or leaving the rocky resting place. The young birds congregate indiscriminately with the adults. A fishing Shag is a very interesting object. He may be watched quietly swimming along, and every now and then springing half out of the water, arching his long neck, and then diving head first into the sea. Soon he reappears again, the body coming into view all at once, it may be close to where he dived, or it may be fifty or a hundred yards away from the spot where he descended. The Shag feeds almost exclusively on fishes, and these are chased through the water with incredible skill. The bird may thus be watched by the hour together swimming and diving, propelling itself by its feet, and bringing the captured fish to the surface to swallow them. At the approach of night the Shag almost invariably betakes itself to the shelter of some cave or fissure; and it is no uncommon sight along the rock-bound shore to see a dozen of these birds hurrying along close to the sea in silence towards the rocks where they sleep.
The Shag breeds in May. Its favourite nesting haunts are the caves and fissures in the cliffs, but where such are wanting, or not available, the bird will content itself with a cranny amongst the rocks of a low island. If plenty of accommodation exists many pairs of Shags will nest in company; where suitable sites are scarce the birds breed in scattered pairs along the coast. It is more than probable that the Shag pairs for life: it returns season by season to its old nesting-place. The nest of this species is either wedged into some crevice of the sides or roof, or made upon a ledge in a cave; sometimes a hole in the face of a wall-like cliff is chosen; less frequently a site is selected amongst the rough boulders on a reef; or even on a ledge of the cliffs where they overhang considerably. In most cases the nest is bulky and made of sticks, stalks of plants, and sea-weed, lined with straws, coarse grass, and turf, all more or less matted together with droppings, decaying fish, and slime, and smelling most unpleasantly. Many nests are enlarged and patched up year by year. The two, three, or four eggs are a little smaller than those of the Cormorant, of a delicate bluish-green where the thick coating of lime does not conceal it. The Shag shows more reluctance to leave its nest than the Cormorant does. The effect is most startling as the big birds dash out of the gloomy sea caves one after the other. The only note I have heard this species utter has been a low croak.
GANNET.
This remarkable bird differs in many important respects from all other pelagic species inhabiting the temperate portions of the northern hemisphere. Outside the limits of the British Islands its only other breeding places in Europe are on Iceland and the Faröes. The Gannet or Solan Goose, the Sula bassana of Brisson and modern naturalists, is one of the most pelagic of birds. Except during the breeding season it is rarely seen near land, the thousands of birds that congregate in a few chosen spots round the British coasts dispersing themselves far out to sea as soon as the duties of the year are over. Like the Albatross, the Gannet may almost be said to live in the air. Its powers of flight are simply magnificent. Occasionally a few odd birds may be observed here and there fishing in the bays, during autumn and winter; but the person who would study its habits and movements thoroughly must visit one of its breeding places. There are many colonies of Gannets round the British coasts, one of the most accessible, and perhaps the most famous, being on the Bass Rock, in the Firth of Forth. There are small ones on Lundy Island and Grassholm; large ones on Suleskerry, Sulisker, St. Kilda, Ailsa Craig, and Little Skellig. The adult plumage of the Gannet is white, tinged with buff on the head and neck, except the primaries, which are black. The bare skin round the base of the bill is blue. The bird probably does not attain its white plumage until nearly four years old, passing through a series of mottled stages of black, brown, and white. The young are hatched blind and naked, but eventually become clothed in dense white down. Other structural peculiarities are the closed nostrils, and the subcutaneous air cells almost covering the body, which the bird can fill with air at will, as they communicate with the lungs. Whether seen at its nest, or when fishing at sea, the Gannet is a remarkably interesting bird. As may naturally be inferred, a bird so light and buoyant as the Gannet does not obtain its food by diving. It is incapable of submerging itself even for a little distance, except by gaining sufficient momentum from a plunge headlong from some distance in the air. Nevertheless, the Gannet feeds exclusively on fishes, which it catches almost like a Tern, by dropping from a great height and seizing or impaling them with its strong bill. The Gannets follow the shoals of fish as they swim near the surface. First one bird, and then another, will be seen to poise itself, and then, with closed wings, to dash downwards, glinting like a piece of white marble in the sun, into the sea, disappearing for a moment, then rising again into the air to prepare for another descent. Many Gannets at these times may, perhaps, be seen swimming, but they are merely resting, not fishing. The captured fish is invariably swallowed at once. The sitting birds are kept well supplied with fish by their mates. These fish, however, are not conveyed to them in the beak, but in the gullet, from which they are disgorged, and left by the nest side to be eaten as required. Very often a Gannet will disgorge several large fish before leaving its nest, whilst many more fish are brought to the rocks than are actually eaten. The Gannet is a voracious eater, and often so gorges itself with food as to be incapable of flight. The power of wing of this beautiful bird is wonderful in the extreme. I have seen the Gannet repeatedly keep the air for hours together, apparently without effort, wheeling in graceful curves, and ascending to vast heights, just as Vultures are wont to do.
Although the Gannet is a resident in British waters, it seldom comes near land except to breed. During the nesting season it is very gregarious, and some of its stations contain many thousands of pairs. Early in the spring Gannets begin to assemble at the breeding places, and towards the end of April nest building commences. The nests are made either on the ledges of the cliffs, amongst the broken rock fragments at the summit, or on the flat table-like tops of pinnacles and stacks. Where the birds are numerous and the accommodation limited, great numbers of nests are crowded together; and as may readily be inferred, such close companionship leads to not a few battles between the birds themselves. Indeed, a sort of guerrilla warfare is being waged constantly, and is by no means one of the least interesting features of the never-to-be-forgotten scene. The nest of the Gannet possesses little architectural beauty, and is generally so trodden out of shape as to resemble a mere heaped mass of rubbish, caked together with droppings, and slime, and filth, giving off an almost unbearable stench, especially on a calm hot day in May or June. Seaweed, masses of turf, straws, moss, and stalks of marine plants are the principal materials. The nest is shaped like a flattened cone, the cavity at the top being shallow. It is no unusual thing to see the birds adding to their nests, even when incubation is in progress. The Gannet lays but a single egg, but if this be taken—as it often is, especially in colonies easily accessible to man—the bird will replace it several times in succession. It is pale bluish-green, but generally so thickly coated with chalky matter—and later with stains—as to hide all trace of this colour. There are few more noisy animated scenes in bird life than a Gannet colony, during the height of the breeding season. The stirring sight once witnessed can never be forgotten. The air, for many yards from the face of the cliffs and high above it, is filled with thousands of flying Gannets; every available spot, on the edges and face of the rock itself, is occupied by a Gannet, the standing birds vieing with each other in uttering harsh cries, the flying birds silently drifting to and fro in a mazy bewildering throng. Many of the flying birds are carrying nest materials; many of the birds standing on the rocks are fast asleep! On every side the Gannets are eyeing you suspiciously, some disgorging fish previous to taking wing, others barking defiance as you approach them, and stubbornly remaining upon their egg until absolutely pushed from it. Rock, sea, and air teem with birds. It will, however, be remarked that none of the birds fly over the land; all keep to the face of the cliffs. At the Bass Rock, numbers of young Gannets used to be taken for food, the proprietor baking quantities, and selling them to the country people round about. The taste for baked Solan Geese, however, is not so prevalent as formerly, and the custom seems likely to die out. At St. Kilda, however, the Gannet harvest still continues to be gathered, and the young birds form a welcome article of food.
