СКАЧАТЬ confusing them in situ. In autumn the Merlins quit the moors. It is difficult to say how far these birds indigenous to our own moorlands migrate; there is evidence to suggest that the movement is limited to a trip to the lowlands, extending even to the coast. On the other hand, the bird is certainly a species with a strongly marked and regular passage in most parts of its extra British range. A word as to the plumage of this interesting Falcon. The cock bird, with his slate-gray upper parts, rufous nape, more or less distinctly barred tail, dark wings, and rufous under parts streaked with dark brown, is possibly familiar to most readers. The hen bird, so far as we can determine, is not only slightly bigger than her mate, but much less handsome in colour. She is dark rufous-brown on the upper parts, each feather with a paler margin, the buff nape patch is paler and much less distinctly defined, the tail is browner, and the under parts are dirty white streaked with brown. This plumage closely resembles that of the young male. During the past quarter of a century we have examined a great many skins of the Merlin, and almost without exception the sexual differences in colour were as described above. There are authorities, however, that maintain that the adult plumage of the female of this Falcon is very similar to that of the male. In this we are disposed to concur, for we have examined an adult female obtained by Dr. Scully in Gilgit (and his sexing of specimens is most reliable, as every naturalist who has had the pleasure of seeing them will agree, the sexual organs being in most cases sketched on the labels attached to the skins), in which the sexual differences of colour were most trifling. It is said that the females are shot off in this country before they can obtain their fully adult dress. In fairness, however, we must state that there is always the possibility of very old females assuming the male plumage, and their apparent rarity may be due to this fact.

Unfortunately the other moorland birds of prey are now rare almost to the verge of extinction; indeed, we regret to say the Merlin itself in not a few localities is fast approaching the same condition. The species that we shall allude to here is the Hen Harrier. This bird, like nearly all the other birds of the moors, is a migratory one, although there is some evidence to suggest that in our islands the movement is to some extent confined to a journey to the lowlands and the southern counties. Formerly this Harrier was a fairly familiar bird on the moors of the south-western counties, where, however, its local names of “Blue Hawk” and “Furze Kite”, indicative of old-time abundance, are nearly all that is left to us. We may remark in connection with this bird that a century ago the male and female (being so much unlike each other in plumage) were almost universally regarded as two distinct species, the latter known as the “Ring-tail” Hawk. Montagu cleared up the confusion by rearing a brood (doubtless from a Devonshire nest), and clearly demonstrated that the two supposed species were in reality the opposite sexes of one. About the South Yorkshire moors the Hen Harrier is practically unknown. Our limited experience of the bird was obtained on the moors of Skye, where we believe it still continues to nest. We have there seen it beating along the hillsides in a slow deliberate manner just above the tall ling, amongst which, in this island, it almost invariably makes its nest, placing it upon the ground. The four or five very pale-blue eggs are often destroyed by sheep; in fact, we were assured by an intelligent keeper in Skye that to this cause alone its diminishing numbers must be attributed. This Harrier reaches the moors in April or early May, and nests during the latter month and the first half of June. The cock is a beautiful bird, with gray upper parts, darker on the throat and breast, the remainder of the under parts and the upper tail-coverts pure white, the primaries black. The hen is somewhat larger, dark-brown above, paler brown below, streaked with rufous-brown; the upper tail-coverts are, however, nearly white as in the male, which fact seems to suggest that they are a recognition mark (Conf. Curiosities of Bird Life, p. 249). The principal food of this Harrier consists of small animals, such as moles, mice; of frogs, lizards, and insects. The bird is also a great egg eater, robbing the nests of other moorland species. Although to some small extent it may prey upon birds, there is nothing in its habits to cause uneasiness to the owner of a Grouse moor; the bird’s comparative harmlessness should secure for it greater immunity from gun, trap, and poison than it at present receives. There are one or two other Raptores we may just allude to here as dwellers on or fairly regular visitors to the moorlands. On the South Yorkshire moors the Kestrel is, we are glad to say, still a fairly common bird. It is fond of the outskirts of the moors, the rough grounds often crowned with ridges—ranges of low cliffs—of millstone grit, and in these it habitually nests. Then the Sparrow-hawk is a frequent visitor to the heath-clad wastes, but chiefly to the borderland and in localities where there are plantations of larch and fir, in which the bird can find seclusion and a suitable nesting haunt. We have often remarked that these moorland Sparrow-hawks quit such areas during winter when small birds are absent. The Rough-legged Buzzard passes over many parts of the South Yorkshire moors on migration, especially in autumn. We have examined many fine examples of this bird, obtained on the Ashopton moors and about Derwent, chiefly birds of the year. The two species of British Eagles must also be mentioned as visitors to the Highland moors, although not exclusively indigenous to them. They are better described as mountain birds, and shall receive more detailed notice in our chapter devoted to the avine characteristics of such localities. (conf. p. 81.) So also may we remark that the Raven will be dealt with in the same chapter. In Devonshire the Raven is still to be found on Dartmoor—one of the few inland localities that it frequents in England nowadays; but elsewhere on the English moors, so far as our experience goes, the bird is but a casual visitant.

       The Lapwing.

      The moorlands, being as they are the least changed districts in the British area, continue to be the resort of a large number of shy birds of the Plover and Sandpiper tribe during the breeding season. In some places no doubt the number of these birds is visibly diminishing, but in the wilder districts there still remain sufficient to constitute a decided ornithological feature. One of the best-known of these is the Lapwing. Fortunately we can still class the Lapwing as a common and even abundant bird in suitable districts, and now that its eggs are protected by law in not a few spots we may hope to see a welcome increase. This beautiful Plover—one of the handsomest of the entire group—is by no means confined to the moors; it is a most adaptive species, and makes itself at home on arable land as readily as in wilder areas, still it is a prominent feature in not a few moorland scenes. Who does not know the sad mewing cries and the restless uneven flight of this Plover, as it rises startled from the ground and commences its plaintive protest against our intrusion? Large numbers of Lapwings breed on the North Derbyshire and South Yorkshire moorlands, as well as on the rough grounds in their vicinity. We remember on one occasion—we have a note recording the fact—seeing a pair of Lapwings drop quietly to the ground just behind a stone wall that separated the moor from the highway. Creeping carefully up to the spot we looked through a chink in the wall and saw the two old birds with four chicks which could not have been hatched many hours. The scene was a charming one. The downy long-legged little creatures were running about picking here and there, their parents standing guard, alert and watchful, yet totally unconscious of prying human eyes not a dozen feet away from them. After watching this family party for some time we intentionally came into view, when the scene instantly became more interesting than it was before. Both old birds rose into the air and commenced wheeling and rolling about just above our head, the female by far the most venturesome of the two. Then she alighted a yard or so away, and with both her broad wings sweeping the ground dragged herself along for a few paces, striving her hardest to get us to follow. But we confined our attention for a time to the chicks. All four of these artful youngsters at the first alarm scattered in as many different directions and hid themselves amongst the heath and grass almost with the rapidity of thought. Search as we might we could find but two, although we knew full well the others were concealed on a patch of ground no larger than an ordinary table. These two chicks we pocketed for specimens, but we were so touched by the way the old Lapwings followed us over the moor crying so plaintively that more humane feelings got the better of us, and we returned to the spot and placed both young birds where we had found them. Such little episodes as these go so far, we always think, in making ornithology so very attractive.

      Another allied species breeding on most of our northern moors (and in some few instances in the south-western counties) is the Golden Plover. There are few more handsome birds of this order than СКАЧАТЬ
