Among the Birds in Northern Shires

CHAPTER I.. By Upland Streams.

BY UPLAND STREAMS.

There are few things more interesting to the lover of bird-life than the comparison of ornithological phenomena as they are presented in various localities, separated, it may be, by but few degrees of latitude. Not only does this apply to the species themselves--for even in our own islands the geographical distribution of birds conforms a good deal to latitude,--but to their migrational movements, their resumption of voice, their seasons of reproduction, their gatherings and movements generally, and finally to not a few habits that appear to be confined within narrow territorial limits. We have already dealt with bird-life in its many aspects in southern haunts with a view to the comparison of avine phenomena with that of more northern localities; we now propose in the present volume to review the most salient ornithological characteristics of certain favoured northern shires, especially with the object of bringing them out in contrast by their comparative study. The ornithologist with a southern experience, studying bird-life in a northern county--say in Yorkshire, for example--will soon find that the avifauna of the two areas, although it possesses much in common, is in many respects different. Birds that he was wont to find common in southern haunts are rare here; others that were scarce in the south, and which he was apt to regard even as rarities, are quite common. Not a few species are met with that are seldom normally seen in southern haunts, and opportunities are afforded him of studying the nesting economy of species, the breeding areas of which are decidedly boreal. Then, again, the change of latitude involves a change of climate, especially in winter; slight, perhaps, it may be, comparatively speaking, but yet sufficient to influence the habits and movements of birds in quite a different way from those prevailing in the milder atmosphere of southern haunts. Birds that sing all the winter through in these southern shires are silent here at that season; others that are sedentary there are of migratory habits in the wilder and colder north--in obedience to those climatic influences that act upon the food supply, and so on. The farther north he goes the more acute will the contrast in avine phenomena become; and in species common to the two areas--to northern and southern counties respectively--he will find differences of from one to two months in the ornithological calendar. Lastly, he will meet with a multitude of interesting forms, both in summer and in winter, that are normally strangers to southern localities at one season or the other, or at both seasons.

We will commence our observations by an investigation of the bird-life along the upland streams--not in their lower and quieter reaches, but at some elevation up the hillsides where the waters hurry and tumble along over rocky beds and between more or less precipitous banks fringed with alders, mountain-ashes, bracken, and brambles. The southern counties can boast no such streams; and even in the wilder south-west of England the becks are wanting in that grandeur that characterizes most of these turbulent northern waters. For twenty years or more we lived surrounded by them and within ear of their noisy clamour; whilst the birds upon their banks were our constant companions summer and winter alike. To our mind the ideal upland stream is one of the most picturesque features in the Peak district. They may be grander and wilder farther north, but with experiences of them in the remote Highlands and the Hebrides in mind, for romantic charm and wealth of bird-life these Derbyshire and Yorkshire brooks, in our opinion, remain unequalled. Almost every valley in the Peak can boast a streamlet of some kind. Some of course are more imposing than others, drain larger areas of upland, and contain a much greater volume of water. Some plough their way across the open moorland, their bed in summer being dry or nearly so; whilst others purl down wooded valleys and along well-timbered bottoms, between the ridges of millstone grit that are such a prominent feature in this particular kind of country. In their higher and wilder reaches such rivers as the Dove, the Wye, and the Derwent--all beloved by the angler for trout and grayling--may be taken as very excellent examples of upland streams. The Rivelin, with its charming branches of Blackbrook and Wyming brook, and itself a tributary of the now polluted and ill-used Don, upon which grimy Sheffield is partly situated, were all favourite streams of ours rich in ornithological associations. So, too, was the Sheaf, with once picturesque Meersbrook, especially in its upper waters between the villages of Dore and Hathersage.

Were we asked to name the most characteristic bird of these upland streams we should unhesitatingly answer, the Dipper. Not that the bird can be regarded as plentiful anywhere; and we know not a few streams where this engaging species has dwindled seriously in numbers during the past twenty years, due partly to the senseless persecution of keepers and others, and partly to the much greater number of people that wander along the banks nowadays compared with years ago. Be this as it may, the Dipper is still sparingly dispersed along most of the streams suited to its requirements. Its exclusive habits tend to characterize it as rarer than it actually is, and its peculiarity of keeping a length of water reserved for itself and its mate creates an impression of absolute scarcity which in many cases does not actually exist. No wonder the old school of naturalists were at a loss to assign a place in their classifications to this curious bird. Brisson included it among the Sandpipers and called it Tringa merula aquatica; but Linnæus, with more discernment, associated it with the Passeres in his genus Sturnus, which is now restricted to the typical Starlings. Modern ornithologists have fared little better, and the poor Dipper, even in quite recent years, has been tossed about from one group to another utterly regardless of its true affinities. In some modern books we find it associated with the Thrushes, in others with the Wrens, but with neither group falling naturally. There may be some of its special characteristics, as, for instance, the coat of down that more or less covers the body below the feathers, due to its peculiar habits and economy; but, on the other hand, the very peculiar character of its nest and eggs (which we regard as of some importance in determining its taxonomic position) seems to suggest that the small group of birds of which the Common Dipper is typical, is not very closely allied to any other existing group, and fully to warrant the separation of these birds from other Passeres into a family apart. Small as this family is, the dozen species of which it is composed are scattered over a very large proportion of the earth's surface. Dippers in one form or another are found over the greater part of Europe, Asia, and North Africa; they occur on the upland streams of the Himalayas, and in the mountains of Formosa. Across the Atlantic they inhabit the hill streams of the Rocky Mountains and the Andes.

Our British Dipper, as probably most readers at all familiar with the bird may be aware, is one of the most sedentary of our indigenous species. Both here and in those parts of continental Europe which the typical species frequents, as well as the slightly different northern form from Scandinavia, the birds keep closely to their native streams summer and winter alike, only wandering from them in the very exceptional event of the torrents becoming frost-bound. Such a peculiarity has resulted in the establishment by variation and isolation of an almost endless number of local races or sub-specific forms. To a slight extent this may be remarked even in our own islands, birds from various localities exhibiting differences of coloration, but when we come to review the Dippers of the entire Palæarctic region the amount of variation amongst them is much more pronounced. The scope of the present little volume forbids a scientific revision of the genus Cinclus; but a glimpse of the sprightly little brown and white bird bobbing up and down like a fleck of foam amidst the whirling waters of a northern trout stream suggests a passing allusion to these interesting facts.

The English local names of the Dipper are not without interest. It is somewhat curious to find that the local name of Water-crow has been applied to this bird not only in Cornwall but almost universally in Scotland. The names Water-ouzel and Dipper are of very ancient application. That of "Dipper" was not "apparently invented in 1804", as Professor Newton suggests in his Dictionary of Birds (p. 151), by the author of the letterpress in Bewick's British Birds (presumably Beilby); for we find it used many years previously (in 1771) by Tunstall in his Ornithologia Britannica, a work which was reprinted by the Willughby Society in 1880 under the editorship of Professor Newton himself! There can be no doubt whatever that the name had been applied much earlier still. The derivation of the words Water-crow and Water-ouzel is not difficult to determine; but that of "Dipper" is open to considerable doubt. To us it seems just as reasonable to presume that the bird received this name from its unique habit of "dipping" in the stream as from its singular dipping or bobbing motion when perched on some stone or rock in the bed of the torrent, as is suggested in Bewick's work on British birds. In some parts of the Highlands the Dipper is known locally as the Kingfisher.
