Шрифт:

As many of the rivers of the northern shires approach the sea they widen into estuaries, the shores of which are the resort of a great variety of bird-life. The Humber and the Tyne on the east coast, the Solway, the Lune, the Ribble, and the Mersey on the west coast of England are capital instances of such. The mud-flats up to tidal limits, often extending many miles inland, are favourite feeding-places of large numbers of wading birds, not only during the two seasons of migration, but throughout the winter months. In summer these places are more or less uninviting; the birds are scattered far and wide, not only over our own uplands and inland waters, but beyond the seas on arctic tundras; in early autumn the birds appear again in small numbers, and as that season advances become increasingly numerous. When these birds of mud-flat and sand-bank depart, little else is left but an occasional Gull, or possibly a laggard wading bird or two that from some reason or another have not migrated with their companions. We might, however, mention that in or near the beds of some of these northern rivers the Ringed Plover breeds. In spring and autumn companies of Terns hang about these estuaries; the Sandwich, Common, Arctic, and Lesser Terns appear from the middle of April onwards; their return is noticed during August and the first half of September. These dates are nearly coincident with those at which we notice these birds in the Devonshire estuaries, save that in autumn the migration continues into October, and during some years is even prolonged into November. Sanderlings, Curlew Sandpipers, and Knots, birds that migrate amongst the latest in spring and breed in the high north, are some of the first to reappear in autumn, even at the end of July or early in August. Common Sandpipers, as their name suggests, are abundant during their short stay at the mouths of these northern rivers previous to passing south. In the Humber district especially, vast flights of Dunlins often appear upon the mud-flats towards the end of August, and remain for the winter. When the rising tide drives them from the muds, they often resort to the fields to wait until the ebb. The movements of these birds are most interesting, as a vast flock wheels and spreads out or closes up with as much precision as drilled troops. Scattered amongst them are many odd Stints and Sanderlings and Ringed Plovers. Curlews, Whimbrels, and Bar-tailed Godwits also appear about these estuaries during migration time, and some of them remain upon them throughout the winter. At the latter season Ducks of various species are regular visitors. Some of these, however, keep well off the land out at sea, only entering the river mouths during rough weather, or at night for the purpose of feeding in the shallower water. One of the most familiar, perhaps, is the Scaup; the Pochard is another, with a much more marked preference for rivers; the Pintail is a third. Companies of Swans from time to time may be observed, usually consisting of Whoopers, and much more rarely of Bewick’s Swans.

During the migration season in spring, and more especially in autumn, these northern river-valleys are frequented by great numbers of land birds on their way to more northern and eastern breeding grounds in Continental areas, or returning south and west to winter in our islands or to cross over them to warmer latitudes. These northern rivers are exceptionally favourable for migration, so many of them trending in the same general direction as the birds are bent on following. Vast numbers of migrant small birds follow such river-valleys as the Tees and the Humber, on their way into Yorkshire, Notts, and Derbyshire, by way of the Don and its tributary streams. It is unnecessary here to dwell upon these species in detail, for we hope to go much deeper into the matter when we come to a study of the migration of birds in the northern shires. We have gathered much evidence in support of this migration during a residence of many years at no great distance from the Humber and certain valleys in direct communication with that important estuary – next, perhaps, in interest, so far as bird-life is concerned, to that still more wonderful locality the Wash, a little lower down the coast.

CHAPTER VIII
ON SEA AND SHORE

It is the bird-life of sea and shore especially that renders these northern shires so much more interesting than the littoral counties of the south and west. Compared with these the southern coasts seem tame and deserted, indeed. This is principally due not only to the fact that so many marine species breed in northern areas only, but also to the much greater strength of migration generally along the coasts. All along the coast from Lincolnshire northwards to the Firth of Forth, and onwards to the Hebrides, St. Kilda, the Orkneys and the Shetlands, we have vast and varied bird populations, not only scattered up and down the shore, but congested here and there where the sea-fowl in unnumbered hosts congregate to rear their broods. The southern counties present us with nothing approaching to this; the wealth and variety of the marine avifauna of the northern shires is one of the most pleasing of their many characteristics.

For the sake of comparison we may here state that along the entire coast-line of South Devon – embracing some of the finest cliff scenery in England and full of sandy reaches, rolling downs, rocky islets and stacks, and lengths of shingle and sand – there are but two typical marine species (at most three, if we include the doubtful Oyster-catcher) that breed, and one only of these, the Herring Gull, in any numbers; the other, the Ringed Plover, is local and nowhere numerous! But how very different is the case when we get round the English coast as far as the Wash and enter that area which for the purposes of the present work we describe as the northern shires. Let us follow this line of varied coast, with its alternating lengths of sand and shingle, buttress-like cliffs, rocky shores, and islets round to the Forth, and briefly glance at the several species that frequent it and breed upon it in succession. We will, however, leave for a future chapter the birds that are more strictly confined to the sea-cliffs, and deal with those only that nest either along the flat shores or low rocky islands.

The first two species that we shall meet with during summer on the sandy reaches of the Lincolnshire coast are the Lesser Tern and the Ringed Plover. The first-named of these is a summer migrant and a late one. We remark it passing up the Devon coast early in May; it reaches its breeding-places by the middle or the third week in that month on the Lincolnshire and Yorkshire coasts, but is later still in Scotland. The return passage is made towards the end of August and through September. Incidentally we may remark that not only this but the other British species of Tern often continue their migrations at night. We have frequently heard the well-known note sounding from the darkened air as flocks of these birds passed north or south along the coast, a short distance from shore. The Lesser Tern breeds in May. It makes no nest, but deposits two or three eggs upon the bare shingle, in spots where the debris of the shore is large – pebbles, broken shells, and the like – not on the fine sand. We may remark that we have taken as many as four eggs in a clutch from this part of the coast. The eggs are very difficult to see on the rough shingle, and during our search for them the distressed little birds flutter and beat about the air uttering their shrill note incessantly, peering down most anxiously, yet displaying no increased alarm when they are actually found and taken. It is a most unfortunate circumstance that this Tern prefers the coast of the mainland to an island for breeding purposes. To this fact its absolute extermination is largely due in not a few localities. There can be no doubt that the three or four other British Terns would have shared the same fate, and become rare and local long ago, in England especially, had they not bred in much less accessible spots, as on the Farne Islands, for instance. Upon the same coast the Ringed Plover also breeds. This bird is a resident in the British Islands, but subject to a good deal of local movement during autumn and winter. We shall find, however, that it always prefers to deposit its four pear-shaped eggs upon the finest brown sand, where scarce a pebble or a shell can be seen. The reason for this curious choice is because the eggs are only spotted, not blotched, and therefore they best resemble such a resting-place as is chosen for them. They would be much more conspicuous upon the shingle where the Tern’s eggs rest. Both eggs have a buff ground-colour closely resembling the sand, but those of one bird are heavily marked to harmonize with shingle, those of the other finely spotted to imitate grains of sand. These birds, again, evince little or no anxiety during our search for their eggs; they seem fully aware that the best policy is to leave them to the safety ensured by their protective coloration. They are laid in Lincolnshire in June, and fresh eggs of both species may be got together during that month; and during the daytime the nearly vertical sun renders incubation scarcely necessary. Both these species may be found breeding here and there along the shore right up to the Humber, and from Spurn still farther northwards until the coast assumes a more rocky character as we approach the famous Flamborough headland. When we reach the rocks a little Passerine bird makes its appearance, and this is the Rock Pipit. As its name implies – and it is a most appropriate one – the bird is only found breeding on a rocky shore. Given this, its distribution round our entire coast-line is a very general one. It breeds as commonly on the rocky shores of Devon as on the Hebrides and the Farne Islands; but there are no Rock Pipits on the flat coast-line between the Thames and the Humber. We meet with it again, however, here on the Yorkshire coast, and cannot easily mistake it, for it is about the only small bird that dwells in such a haunt during summer.

Travelling northwards again until we reach the coast of Northumberland, where between the towns of North Sunderland and Berwick we shall find another length of shore of great interest to the ornithologist. Indeed between these two points are situated the famous Farne Islands, the grandest and most imposing haunt of sea-birds round the entire English coast. On the mainland, nearly opposite to the Farne Islands, there is a long reach of sand dunes between the sea and the cultivated land, and these are frequented by at least one bird of exceptional interest. We may dismiss the Gulls that beat along in restless flight, and pay small attention to the Common Buntings that here justify their name, and for the time being confine our observations to the Sheldrakes that haunt this part of the coast. These sand dunes are an ideal locality for such a bird. Should the tide chance to be out, more likely than not this species will be detected upon them. It is a shy and wary fowl, though, and we need the aid of our powerful binocular to bring it within range of much detailed scrutiny. This Duck is to our mind quite the handsomest of its family in our islands, a combination of very pronounced black, white, and chestnut, with a dash of crimson and pink on bill and legs thrown in. You may watch it thus through your glass walking in a somewhat stately way, not waddling like a more typical Duck; but should you attempt a much nearer scrutiny the big bird unfolds its broad party-coloured wings and seeks a more secluded resting-place. Should the time be high-water, and the blue sparkling sea reaches almost up to the links, most probably a few Sheldrakes will be observed flying over the water up or down the coast. The flight is very characteristic, unlike that of the true Ducks, more like that of a Goose or a Swan, the wings moved up and down with slow measured strokes, so very different from the rapid beats of the bird’s Anatine relations. In this species the sexes are very similar in colour; indeed the chief external difference is the absence of the frontal shield from the female. Following the almost universal law, this conspicuous hen bird takes good care to conceal herself from enemies during the critical period of incubation, and lays her eggs at the end of a long and often winding burrow in the sand. In this particular district a rabbit hole is almost invariably selected, and some of the chosen burrows are so intricate that we may spend hours in the fruitless search for the exact position of the nest. This is usually made at the end of the burrow, and consists in the first place of a handful of dry grass – possibly a rabbit’s old abode; but as the creamy-white and fragile eggs accumulate (to the number of a dozen or sometimes more) the old birds surround them with down of exquisite softness and lavender-gray in colour. As is generally the case where both sexes are showy, and incubate in covered or concealed nests, the male bird takes his due share in the duty of hatching; but so careful are the birds in relieving each other – usually at morning and evening – that they seldom betray the whereabouts of the nest. The young birds, soon after being hatched, quit the burrow and betake themselves in their parents' company to the sea-shore. In this locality the bird is certainly becoming rarer owing to the way the young are captured and the eggs taken by fishermen and others. We once inspected an entire brood of a dozen ducklings that a fisher lad was rearing at Seahouses. He had them confined in a small pen and fed them chiefly upon sand-hoppers, which they were marvellously adept at capturing as he threw them down one by one amongst the downy little creatures. From Holy Island right round to the Forth, this Duck may be met with breeding, preferring in the latter locality the numerous sandy islets. Round the coasts of Scotland it becomes even more numerous and widely dispersed.

We will now retrace our steps to the Farne Islands and make a brief inspection of such birds that build their nests on the flat surface, reserving the cliff-haunting species for our next chapter. Repeated visits to these islands only increase their charm. A single visit is bewildering, renewed acquaintance impresses their wonders upon us and enables us fully to realize the grandeur of the scene and more completely to enjoy the avine wonders of the place. Apart from their bird-life, there is a strong human interest clinging to them, for Grace Darling casts a halo of romance around them by her daring deed long years ago, and which is still a stock subject for conversation up and down the coast. These rocky islands lying a few miles off the shore are nowadays almost a perfect sanctuary for sea-birds. This was not always so; for we can recall the time when the eggs especially were gathered in such a wholesale way that the wonder is there were any sea-birds left there. Strict protection is now the rule, and visitors are generally kept under such close supervision that the lifting of an egg without permission is almost an impossibility. There are, of course, a good many birds on and off these islands at all times of the year; now and then, especially in winter or during migration time, a rare straggler of some non-indigenous British species appears, and the light-keepers have repeatedly assured us that at intervals the sea around them during winter often swarms with Ducks and other northern birds. It is, however, in spring and summer that the islands become crowded with their normal inhabitants – Gulls, Terns, Eider Ducks, Cormorants, Ringed Plovers, Oyster-catchers, Guillemots, and Puffins – assembled there for the express purpose of rearing their young. One of the most characteristic birds of the islands is the Lesser Black-backed Gull – in fact the entire group may be regarded as one vast colony of this species, and perhaps the most densely populated one throughout the length and breadth of the British archipelago. These birds return to the islands – coming from the south from many parts of the German Ocean and the English Channel – early in spring, but the exact date varies a good deal in different years. In some seasons they return en masse as early as from the middle to the end of March; in other seasons not before the middle of April. A month later they are engaged in nesting duties. The date of breeding, however, varies little, and the eggs are invariably laid during May and June. On approaching some of the islands, the first impression is that this Gull monopolizes the whole of the ground, as it occurs in such vast abundance. The air seems full of them, the ground and bare rocks are crowded; and as our boat finally grates against the rough beach and we eagerly jump ashore all becomes noisy excitement – a perfect babel of protesting cries that is persistently kept up until we leave the place. We shall find that the nests vary a good deal in size, some being little more than hollows trampled out amongst the dense beds of campion and thrift, others more substantial and composed of pieces of turf, sea-weed, stalks of herbage and grass. The eggs are three or four in number, and subject to an incredible amount of variation in colour – greens, olives, browns, and grays of almost every possible shade representing the shell tints; browns and grays the markings, which take the form of round spots, blotches, streaks, either evenly distributed over most of the surface, scattered here and there, or forming zones round the end. Right through the summer these Gulls are employed in rearing their young, the period being unusually prolonged because so many of the first clutches of eggs are taken for culinary and other purposes. During the latter part of August and throughout September these Gulls and their young leave the islands and work their way southwards, scattering far and wide over the seas, following the shoals of herrings and sprats and other fish, some of them possibly wandering as far as the Spanish and north-west African coasts. A few Herring Gulls breed here and there among the other species, but this bird has very few large colonies in the northern shires. This is the one species of Gull that breeds on the south coast of Devon, and there its colonies are larger than any we have visited elsewhere in the British Islands. Scattered pairs, however, may be met with here and there along the coasts, and in some few inland spots throughout the northern shires. The Kittiwake also breeds in numbers at the Farnes, but we will reserve our notice of it for a later chapter.

Next to the Lesser Black-backed Gull the Terns are certainly the most numerous and most interesting birds. Three out of the five British species return each spring to these famous islands to breed. The Roseate Tern, rarest of all the indigenous species, used formerly to breed here, but it eventually became extinct, although from time to time an odd pair or so are observed in their old-time haunts, so that the bird may re-establish itself in them, more especially as the sea-birds are now so strictly preserved there. The three regular breeding species are the Sandwich Tern, the Common Tern, and the Arctic Tern. All are summer migrants only to the British Islands. The Sandwich Tern, by far the largest of the three species, arrives at the islands during the last half of April, as a rule, but some seasons is not seen until the beginning of May. There is much in their early movements that reminds us of the actions of Rooks just previous to nesting. Every morning for perhaps a month after their arrival they assemble at the islands and stay for a short time, previous to dispersing over the surrounding sea to search for food, lingering longer and longer as the actual breeding time approaches, until they finally decide upon a spot to nest, and about a week after this the first eggs are laid. The laying season lasts a month, say from the middle of May until the middle of June. The earliest young may be remarked about the latter date, and from that time onwards rapidly increase in numbers from day to day. July is a busy month indeed for the parent birds. In exceptionally early seasons some of the young are able to fly by the beginning of August, and by the end of the month the birds quit the breeding-place, and finally desert the vicinity of the islands during the first week in September. Sometimes the autumn exodus is made, but the birds return in a day or so and linger about the islands before finally taking their departure south. The Sandwich Terns do not always breed in exactly the same spot every season. Sometimes an exceptionally high spring-tide will wash away most of the eggs, and then the poor birds move to another situation, perhaps to another island, and try again. This happened in the summer of 1883, and we saw the beach literally strewn with broken egg-shells, the sole remains of the wrecked colony. On our way from the beach towards the barer rising ground in the centre, where the main colony chances to be established, we pass many outlying nests, not only of this Tern, but of Gulls and Eiders. Birds are rising from all parts of the ground, and gradually congregating into a dense bewildering, drifting, noisy throng above our heads. At last we reach the colony of Sandwich Terns, and there we find for an area of many square yards the ground literally covered so closely with eggs that to walk amongst them without breaking them is almost an impossible feat, not only because the nests are but a few feet apart, but because the eggs themselves so closely resemble the ground in colour. The nests are slight enough, many of them nothing but hollows in the ground, some of them with a few bits of weed and grass loosely arranged, and chiefly round the margin. The two, or less frequently three, eggs are very beautiful objects, and vary enormously in the character of the markings. The ground colour may be any shade between rich buff and dull white; the markings are brown of many shades, and ink-gray. These latter vary considerably in shape and size, from large irregular blotches that conceal nearly a third of the shell to splashes, spots, and streaks, sometimes distributed over the entire surface, or in zones, or irregularly here and there. During the whole period of our stay the birds remain above us, fluttering and gliding to and fro uttering shrill notes of alarm.

The Arctic Tern, on an average, arrives later than the preceding species, generally about the first week in May, sometimes not before the third week in that month. A week or so elapses before the birds finally settle down to nesting duties, so that the eggs are seldom laid before June, exceptionally during the last few days of May. As a rule the breeding season is over by August, and the bulk of the birds quit the islands in the first week of September. In later seasons they may not leave until the end of that month, and a few in rare instances linger into October. The eggs are generally laid close to the water’s edge, and so far as our experience extends (and that is a rather wide one, for we have visited colonies in many parts of the British area) no nest is ever made for their reception. They are placed upon the bare sand and shingle, and upon the line of rubbish that marks the limit of the highest water-mark. Two or three eggs are laid for a clutch, varying from buff to olive and pale-green in ground colour, heavily spotted and blotched with brown of many shades, and gray. Lastly, we have the Common Tern, a bird that arrives and departs at about the same dates as the preceding species. We generally found the breeding-places of this Tern at a greater distance from the water than those of the Arctic Tern, amongst the grass and sea campion on the higher parts of the island. As our boat approaches the nursery of this Tern, numbers of birds may be seen squatting on the beach or swimming about in the rock pools. These are the first to take alarm, and as we finally land others rise from the island, and the air is soon filled with screaming birds. The colony is established on some rising bare ground, and the eggs are laid in scanty nests – hollows lined with bits of grass and stalks of marine plants. The eggs, two or three in number, very closely resemble those of the Arctic Tern, but are larger, rounder, and never appear to have any olive or green tint on the shell.

Many pairs of Eider Ducks also breed upon the Farne Islands, placing their nests amongst the campion and long grass, in crevices of the lichen-covered rocks, or in holes in the ruins that are to be found on some of the islets. These Eiders are remarkably tame, and allow the observer to watch them as they brood over their eggs. The male birds, however, are much shyer, and never come near the nests at all, spending most of their time upon the sea off the islands. Then the Ringed Plover breeds here in small numbers, also the Oyster-catcher (a noisy, shy bird enough), and not a few Rock Pipits. Upon an outlying reef the Cormorants have their colony – a dirty, evil-smelling spot, which apparently by common consent is shunned by all the other species. This islet is low, not more than a dozen feet above the sea in its highest part, sloping to the water’s edge on one side. Where the huge nests of the Cormorants are built there is scarcely a trace of any vegetation; everything is more or less covered with droppings, and decaying fish are strewn here and there – the whole place smelling most offensively on a calm hot day. These nests are made of sea-weed, stalks of marine plants and turf, and many are lined with green herbage. The three or four long oval eggs are pale-green, but so thickly coated with lime and dirt that all trace of this is hidden until they are washed and well scraped.

The Farnes are also a great breeding resort of the Puffin (called “Coulter-neb” by some people because its beak closely resembles the coulter of a plough), some of the islands being so undermined by their burrows that almost every few steps we sink deep into the soft loamy soil. During the non-breeding season these birds disperse far and wide over the sea, roaming immense distances from their birthplace, but as spring arrives they collect at the old familiar spots to rear their young. Puffins cannot be regarded as common about the Farne Islands until April, but from then until the end of the following August they are one of the most abundant species at them, although, owing to their subterranean habits, the fact is not very palpable to ordinary observation. These birds excavate a long burrow in the soft soil, often extending many yards underground, and at the end, upon a handful of dry grass perhaps mixed with a few feathers, the hen bird lays a solitary egg, dull-white in colour, very sparingly marked with pale-brown and gray. When the colony is approached such birds as may chance to be above ground soon betake themselves to the sea; those in the burrows remain to be dug out before they will usually budge from their egg, resenting this by bites and scratches dealt in the most savage manner. There is something immensely ludicrous about the look of a Puffin as you drag the struggling bird into the daylight; but we would warn those who might essay the experiment to encase their hands in strong gloves, or they may repent the business. Had space permitted, we should have liked to say something about the curious transformation the beak of this bird undergoes as the pairing season approaches, but we must wait for a future opportunity. Most, in fact all, of these species breed in many other parts of the coasts of the northern shires, but we have elected to describe them here, for the Farne Islands are probably the most accessible locality and admirably situated for studying all these birds within a very small area.

The bird-life at sea off our northern shires is replete with interest at all seasons of the year. In summer, in the neighbourhood of the great breeding colonies of sea-fowl, the surrounding seas for many miles are full of animation, the birds scattering from these home centres far and wide in quest of their finny prey. What a variety of birds we meet with thus, each searching in its own peculiar way for sustenance! How varied their actions; how diversified their habits and economy! In winter these self-same waters are the home of countless birds that migrate from arctic latitudes to spend that season where food is ever plentiful and the water always open. Hordes of Ducks and Geese swell the more sedentary avine populations, or replace such species as Terns, that migrate or wander south with the approach of winter. Vast numbers of Divers and birds of the Auk tribe move south to these seas off the northern shires; Gulls in uncounted hosts do the same. At varying distances from the land armies of these sea-fowl migrate south in autumn and north in spring; sometimes for days in succession Gulls or Skuas, Terns, Gannets, Guillemots, and so on pass to and fro according to season, these avine movements being on a much grander scale than ever we remark on our southern coast lines.

From shore, on this bright May morning, for instance, there is nothing to indicate that much of special interest is to be seen among the birds at sea. From where we stand, near the old-fashioned little quay of this northern fishing village, redolent of tar and stale fish, the sparkling water right away to the headland yonder, and still beyond to the line of the horizon where blue sky and blue sea seem to meet in an indistinct haze, is apparently deserted of bird-life. But we will get aboard this well-found taut little coble, hoist the brown sail and put her nose before the spanking breeze, and see what birds we may fall in with during a few hours' cruise. Behind the headland yonder, and at no great distance from land, a mixed company of Terns are fishing. There are few prettier sights than this amongst bird-life on the sea, especially should a shoal of fry chance to be swimming close to the surface. Above the moving mass of glittering fish the snow-white looking Terns flutter and poise and drift to and fro in a constantly-changing throng; many birds are swimming above the shoal, and every few moments one of the flying Terns drops down like a stone into the water with a splash that we can hear half a mile or more across the sea. The force with which they descend is scarcely sufficient to immerse their light bodies, and before the spray has cleared the bird is either up again into the air, or swallowing the captured fish whilst sitting on the surface. A few Gulls are flying about close by, but these birds prefer larger game; although occasionally they will chase a Tern that may chance to be passing with a tiny fish and endeavour to make the poor little bird drop its capture. Out in the offing the Gulls are much more numerous, for there the fishing fleet is at work, and the birds hover around ready to pick up any unconsidered trifles that may chance to come in their way. A mile or so off the headland the sea is literally alive with birds of the Auk tribe that are breeding on the long range of cliffs. Here we renew our acquaintance with the comical-looking Puffins – hundreds of them swimming about, diving at intervals, preening their plumage, and disporting themselves generally. Many of them allow the bows of the coble almost to reach them before they dive with startling speed and reappear some distance ahead or astern, the first thing they do upon reaching the surface again being to look about in all directions for any possible further danger. Mingled amongst them are the Guillemots and Razorbills, the one bird easily identified by its long pointed bill, the other by its deep flattened one crossed with a conspicuous white line on either side. The Razorbill may be further distinguished by the white streak of plumage which runs from the base of the upper mandible to the eye. In the Ringed Guillemot, a form of the Common Guillemot, the white streak extends backwards behind the eye. Both birds are very similar in their actions out here at sea, swimming and diving with great celerity. Here and there small parties of one species or the other may be seen flying swiftly along just above the waves on their way to or from the headland where they are now breeding. They feed on fish – here in these northern waters young herrings and coal-fish are favourite fare – crustaceans, and molluscs, chasing the former with great dexterity through the water, searching for the latter in soundings amongst the weed and rocks. We shall have more to say about these Auks in the following chapter. They are all resident in British seas, coming to the land in summer to breed, and during the remainder of the year wandering far and wide over the waste of waters, and then visiting coasts and estuaries and harbours where they are never seen during the season of reproduction. Here and there in our northern waters, but only off the western coast-line during summer, we may frequently fall in with Petrels and Shearwaters. These birds are the most pelagic of all, and only visit the land to breed. The Fulmar is the largest indigenous British species, and looks very like a Gull as it flies about over the water. The Manx Shearwater comes next in size, but it is a dark-plumaged bird on the upper parts, only white below. Its long wings are very noteworthy, as it skims and dashes about round our boat. The Fork-tailed Petrel comes next in point of size. This and the following species are more nocturnal in their habits, but equally as pelagic as the foregoing. Lastly we have the Stormy Petrel – the smallest of web-footed birds – perhaps the most widely and commonly distributed of all, and often met with not only in our northern seas during summer, but as far to the south as the English Channel, in which it has at least one known nesting station. None of these birds are known to breed anywhere along the east coast of England or Scotland. The typical Petrels may be readily identified by the sooty-black plumage, relieved by a patch of white across the rump and the upper tail-coverts. These small Petrels rarely alight upon the sea to swim notwithstanding their webbed feet. They flutter often close to the big waves, and may then be seen to drop their legs downwards and to pat the water with their feet, seeming sometimes literally to run down the glassy surface of some huge roller. We shall have occasion to enter into more details respecting all these Petrels in the following chapter.
