ON CRAG AND SEA-CLIFF.
The bird-life of the inland crags nowadays is comparatively limited, but what it lacks in numbers is to some extent made up in interest. Time was when the Golden Eagle bred on some of these inland precipices of the northern shires; when the Raven and the Buzzard made them their home. For the purpose of the present work we propose to glance at the few birds that frequent the various crags and rocks—chiefly of limestone and millstone grit—of South Yorkshire and North Derbyshire. They may be taken as typical of many similar localities in the northern shires. It would certainly be difficult to find more grandly romantic scenery than is contained in the district of the limestone rocks of the Peak—in such spacious valleys as Dove Dale, Monsal Dale, and Millers Dale, or in such savage glens as are in the vicinity of Castleton. As examples of the crags of millstone grit we have the noble range of rocks known as Wharncliffe, that crest the valleys like a series of colossal bulwarks, below which is a sea of rolling wood and bracken. It is hard to believe that so much beautiful scenery still remains, surrounded as it is by some of the blackest towns and grimiest centres of manufacturing industry in the British Islands.
One of the commonest birds throughout this district of crags is the Jackdaw. In the south of England this bird perhaps shows more partiality for marine cliffs; inland, as in Yorkshire, it frequents churches and other buildings. Perhaps this is because such inland cliffs are not so common in the south. There is scarcely a rocky glen in the Peak that does not echo the Jackdaw’s cackling cry. At Castleton there is an exceptionally fine colony established in the lofty cliffs at Devil’s Hole, and which are crowned with the crumbling ruins of the keep of once-famous Peveril Castle. Here many times we used to stand at the mouth of the vast yawning cavern, in which the rope-makers are established, as the dusk gathered, and watch the noisy Daws come home to roost. Usually in one compact flock they came, sometimes in several detached parties, and after wheeling and fluttering they finally settled upon the scraggy trees growing out of the rock face. Their cackling cries made the grand old gorge echo again—a chorus that was kept up till their sable forms could not be distinguished in the evening gloom. They make their nests here in the holes and crevices of the mighty cliffs. Another common bird is the Rock Dove. Whether this white-rumped Dove is the truly feral Rock Dove, or whether they are descendants of tame birds run wild, it is perhaps difficult now to say; but our own opinion leans to the latter view, because we believe that the true wild Rock Dove is found nowhere but on maritime cliffs. Whatever their origin, however, here the birds are now, and wild enough. Their abundance is reflected in the names that they have inspired for “Dove” river, and “Dove” dale, both of them famous haunts of these birds. They nest in crevices of the limestone crags, and their habits generally are very similar to those of their relatives along the coast, which they also resemble closely in appearance. Another, yet much smaller colony of these Doves, is to be found in the range of crags that crest the right-hand side of the Rivelin Valley going westwards, close to the Norfolk Arms at Hollow Meadows. We can state from long personal observation, confirmed by keepers and others, that these birds arrive at this place in February, and after rearing several broods during the spring and summer and early autumn, that they leave in October. We have seen these birds perch upon a narrow rail fence on the edge of the crags they frequent. Vast numbers of Starlings also build in these places up and down the Peak and elsewhere. Another very common species is the House Martin. There must be many thousands of nests of this bird in the dales of North Derbyshire alone—a profoundly interesting fact, which indicates that such situations were invariably selected in prehistoric times before such things as houses and bridges were in existence. Talking of bridges brings to mind the fact that on some of the railway viaducts in these dales the copings are so thickly studded with nests in some places as to hide the masonry. We ought also to mention that the Kestrel breeds commonly in these limestone crags, and not a few Redstarts and Wheatears have their homes in crevices among them, at a lower level and near the ground, of course. Swifts are equally common, and in their choice of a haunt suggest a habit that has been retained from a remote period, although changed by many individuals in more recent times. We might also mention that the Peregrine Falcon still breeds locally on some of these inland crags of the northern shires, especially in the Lake District.
So far the inland crags; we will now proceed to a study of the bird-life on the sea-cliffs of the north. It is in these localities again that the northern shires show to advantage over most southern counties in the matter of their bird-life. Nowhere in the south can be found such vast bird bazaars as those that are established in such wonderful abundance upon the sea-cliffs of the northern shires. From Yorkshire northwards to the Hebrides and the Shetlands, one stirring scene of bird-life after another in bewildering numbers crowd upon the observer. From Flamborough’s cliffs to the Pinnacles at the Farnes; thence onwards to the Bass Rock, and across the Highlands to the Hebrides and to St. Kilda in one direction; or up the east coast of Scotland to the wall-like crags of Sutherlandshire and Caithness, and across the Pentland Firth to Orkney and on to Shetland, in another, what famous bird-stations may be found! We will visit a selection of these in turn, commencing our inspection upon the noble headland at Flamborough, at Speeton and Bempton.
The Razorbill.
Some of the finest cliff scenery in the north of England lies between Flamborough Head and Filey on the Yorkshire coast, and what is of more importance from an ornithologist’s point of view, its bird-life is correspondingly impressive. We have many fine cliff-scapes in the south of England, but the birds are disappointing, because they occur in small numbers only, or are absent altogether, as is the case in South Devonshire, for instance. There are few such haunts of Guillemots and Razorbills in the northern shires of England as are located upon some of these grand cliffs. During the non-breeding season they are practically deserted by sea-fowl, left to the undisputed possession of Jackdaws and Rock Doves. But with the approach of spring a great change comes over the scene, and Gulls and Auks begin to assemble once more upon the famous cliffs. Large numbers of eggs, especially of the Guillemot, are taken every season, and prove a welcome source of income to the intrepid climbers who risk their lives in gathering this somewhat unusual harvest. From the summit of the cliffs but little can be observed of the stirring scenes going on upon the rock face. The ground at the top is too sloping to peer over, and it is only here and there where the sea has made a deep indentation, and a view of the cliff face can be seen from the opposite side of the gorge, that we can obtain some faint idea of the bird wonders of the place. For more years than "the oldest inhabitant" of Bempton or Flamborough can recall, the birds have bred here in enormous numbers and have been as regularly robbed. The Guillemots and Razorbills and Puffins are somewhat irregular in their date of return to the cliffs in spring. Sometime towards the end of April is perhaps an average date, although they have been known to come back as early as February (1884). At the Farnes they are apparently earlier, assembling usually some time in March. The young and old birds generally leave the breeding-places for good during the last ten days of August in both of these localities. The eggs of the Guillemot are the easiest to obtain, being laid upon the ledges and in the numberless little hollows about the cliffs; the Razorbill deposits its big solitary egg in a crevice where in not a few cases it is absolutely safe from man; the Puffins, breeding nearer to the top of the cliffs, lay their single egg in burrows. It would be impossible here to describe the wonderful variety in the eggs of the Guillemot: they are by far the most beautiful of any of those of the sea-fowl. Great numbers of these eggs are taken for food; and we can remember how the climbers at Flamborough used to return home to breakfast hungry as Hawks, and break the pretty eggs into the frying-pan with the bacon—forming a meal a gourmand might envy, provided his appetite has been sharpened by a long morning in the bracing air that blows in from the German Ocean. The “Pinnacles” at the Farne Islands are another famous haunt of the Guillemot; the most attractive of all the breeding-stations of this species throughout our islands, owing to the exceptional ease with which the birds can be observed. These pinnacles are a group of flat-topped rocks, rising perpendicularly from the sea, close to one of the islands, from which a good view can be obtained right on to their table-like summits. These are crowded, densely packed in fact, with a struggling mass of Guillemots. When the birds dash off and fly down headlong into the sea, a still more extraordinary sight is presented; for all over the surface are strewn hundreds of eggs—like great pears—of almost every conceivable hue and pattern of marking. The Guillemots are comparatively silent; but the scene is noisy enough, because on the sides of the perpendicular rocks numbers of Kittiwakes are nesting, and their cries are incessant, sounding high above the surging sea and the whirring of the wings of the departing Guillemots. Into many of these Kittiwakes' nests we can look from the summit of the island adjoining, and are thus able to count the eggs or young as soon as the brooding birds are driven off.
The Gannets.
Our next rocky haunt of sea-fowl lies far away to the northward, and is the widely and justly famous Bass Rock in the Firth of Forth. This is another favourite locality of ours; we have visited it repeatedly, and the stirring scenes of bird-life we have witnessed there each time are indelibly fixed upon the memory. It was at the Bass that we went through our apprenticeship to marine cliff-climbing, and where we first made the acquaintance of the Gannet at home. As most readers may know, the Bass is one of the few grand breeding-places of the Gannet in the British archipelago. There are several other rock-birds breeding in some plenty upon the Bass, but the Gannet stamps the rock with its individuality, and all other species are overpowered and comparatively lost amidst its numbers. Perhaps we might make an exception in the case of the Puffins. There is a large colony of these birds established in the walls of a ruined fortification facing the sea, and Puffins may be seen repeatedly coming and going in their usual hasty way. There are many more of these birds breeding here and there about the rock, but this, so far as we know, is the largest congregation. The Gannet is a thoroughly pelagic bird, and only comes to the land to breed, retiring once more to the sea as soon as its young can fly. During the late autumn and throughout the winter the Bass is practically deserted by birds. At the end of March or during the first half of April the Gannets begin to assemble at the time-honoured nesting-place. At first their stay is fleeting, but it gradually becomes longer and longer until nest-building commences, and from that time onwards the Bass is the grand head-quarters of many thousands of Gannets. It has been computed that at least twelve thousand adult birds frequent the Bass; probably this under-estimates the actual number, although we must remember that in 1831 Macgillivray gave twenty thousand. In any case, judging from the most reliable information obtainable, the Gannets seem to be on the decrease. Throughout the summer the Bass is literally vignetted in a throng of ever-moving Gannets; but even at this season many of the birds fly long distances out to sea to feed, coming home stuffed with fish, lots of which are disgorged at the nests. Numbers of the birds begin nest-building at the beginning of May, but, as is the case with Rooks, the operation is not commenced simultaneously by all, and a fortnight later, when many of the nests contain an egg, there are a good number of others in an uncompleted state. At this time many of the birds flying about will be remarked with pieces of turf or other material in their bills, which they will thus carry for a long period without attempting to alight and work it into the unfinished nests. The grand home of the Gannets here is situated upon the north, north-east, and west cliffs. Here on the grassy downs, near the edge of the cliffs, numbers of Gannets may be seen standing quietly, some fast asleep with their head buried in the dorsal plumage. We have caught Gannets when thus asleep, but care must be exercised to grip the bird firmly round the neck, or a stab from the formidable beak will reward the would-be captor’s rashness. The nests are made almost anywhere—at the top of the cliffs amidst the broken rocks and crags, lower down the cliffs where any ordinary climber can reach them, and, most numerously of all, on the ledges far below which are only accessible with the aid of a rope. To say the least, the nest is not a very attractive one; it is often trodden out of all semblance to such a structure, and frequently covered with droppings and slime, whilst around it are dead and decaying fish, many of them disgorged when partly digested. The hot sun soon completes the work of decomposition, and generates a fearsome stench which it requires all the fortitude of an enthusiastic ornithologist to tolerate. The nests are made of sea-weed, turf, straws, and scraps of moss, the soil from the turf being trampled into a mortar-like mass and binding the whole together. In a shallow cavity at the top of this cone-like structure a single egg is laid, originally white coated thickly with lime, but soon becoming stained into a rich brown from contact with the big webbed feet of the parent birds. Numbers of nests in some spots are crowded together, often so closely that the cliff is literally white with sitting birds. The noise is deafening. The Gannets in the air are quiet enough, gliding to and fro in a bewildering throng, but the birds on the cliffs and the grassy downs at the summit, those that are standing or sitting, keep up a never-ending chorus of harsh cries. As we wander to and fro inspecting the dwellings in this curious city of birds the indignant owners bark defiance with sparkling eyes, and only tumble off their solitary egg when prompted by feelings for their own personal safety. They are quarrelsome birds too, possibly because so very overcrowded, and fights and sparrings are continually taking place. Every now and then two birds will each seize the other in its powerful bill and go tumbling over the cliffs together, not to separate until they have perhaps fallen a hundred feet or so, when they will part, and soon lose their identity among the drifting crowd that circles about the face of the cliff in never-ending activity. All the time of our stay birds are coming and going, dropping lightly on to the land or soaring upwards into the air; whilst the sea below is well sprinkled with birds, and some distance down the Firth many others may be seen busily engaged in fishing. The scene becomes still more animated when the young are hatched. At first these are ugly, ungainly-looking objects, blind, and covered with dark-gray skin. This, however, is soon clothed with dense down of dazzling whiteness, which in its turn is succeeded by a speckled plumage—brown spotted with white. The young birds pass through several stages of plumage before they acquire the white livery characteristic of their parents; neither do they breed until they are four or five years old. A few of these party-coloured immature birds may be detected amongst the crowd of adults at the Bass; but, as a rule, these young ones do not congregate much at the breeding-places until ready to propagate their species. In many respects the Gannet is a very remarkable bird. The nostrils are closed, being practically obliterated, the tongue is small and aborted, whilst nearly the entire surface of the body is covered with a net-work of subcutaneous air-cells, communicating with the lungs, and thus emptied or inflated as the bird may desire. We have already dwelt at some length upon the Gannet’s ways of life, and it will at once be seen from the above facts how admirably the bird is fitted not only for an aerial existence, but for withstanding the great pressure of the water during its repeated plunges into the sea from high altitudes.
