THE ALPINE PTARMIGAN (Lagopus Alpinus), IN WINTER PLUMAGE. ONE-HALF NATURAL SIZE.
"The Brown Ptarmigan," continues our author, "feeds for the most part upon the tops of heath (Calluna vulgaris and Erica cinerea), and also picks the leaves and tender twigs of Vaccinium myrtillus and Empetrum nigrum, with the young heads of Eriophorum vaginatum, shoots of Galium saxatile, Carices, grasses, willows, and other plants. It is also said to eat the berries of Empetrum nigrum, accinium myrtillus, and Vaccinium vitisidæa. In two instances I have found its crop filled with oat-seeds, to which it is said to be very partial, although it rarely ventures upon cultivated land. While feeding, it walks among the heath, selecting the fresh tips of the twigs, which it breaks off nearly of the same size, the largest pieces not exceeding half an inch in length. Along with these substances, fragments of white quartz, from one-twelfth to two-twelfths of an inch in diameter, are found in the crop and gizzard, being introduced for the purpose of aiding the action of the latter in comminuting the food. When the Brown Ptarmigans have filled their crops they repose among the heath or bask under a sunny bank, under the shelter of the shrubs or tufts of herbage. On ordinary occasions this species does not fly much, but keeps concealed among the heath, seldom choosing to rise, unless its enemy comes very near. On the approach of danger it lies close to the ground, when, being of a colour not contrasting strongly with that of the plants around, it is with difficulty perceived by rapacious birds." When traced by a dog, it either runs to some distance or squats at once, and often remains thus concealed for a long time, or again runs and squats. "I have seen them," continues Macgillivray, "run in this manner for four or five hundred yards before they were put up. On such occasions the male is generally the first to rise. He erects himself among the heath, stretches out his neck, utters a loud cackle, and flies off, followed by the female and young, affording by their straightforward, heavy, though strong flight an easy mark to a good shot."
The Red Grouse flies low, heavily, and in a direct course, moving its wings rapidly, sometimes, especially when at full speed, with a whirring sound, and then descending with almost motionless pinions.
"If disturbed when feeding," says Macgillivray, "the male often boldly starts up and utters a loud cackle, which may be imitated by quickly repeating the syllable 'kok' with a deep voice. In spring and summer they are often heard uttering the same sound without being disturbed, either as a call of defiance to their fellows, or as a warning or protection to their mates and young. Early in the morning as well as late in the evening, but occasionally through the day, you may hear on the moors a loud cry, which is easily syllabled into 'Go, go, go, go, go-back, go-back;' although the Celts, naturally imagining the Moor Cock to speak Gaelic, interpret it as signifying, 'Co, co, co, co, mo-claidh, mo-claidh'—that is, 'Who, who (goes there?) my sword! my sword!'" These birds pair early in spring. The nest is made in a hollow of the ground among the heath, and is irregularly formed of bits of twigs, grass, and a few feathers; the eggs, from eight to twelve in number, are oval, and of a yellowish white, yellowish grey, or brownish yellow colour, clouded, blotched, and dotted with blackish and amber brown. The young leave the nest soon after they are hatched, and are tended by both parents, the mother showing much anxiety for her progeny, and endeavouring by affecting lameness to lure any intruder from them. The young are soon able to fly, and all keep together till the end of autumn, when several flocks unite and form a pack, continuing together till spring arrives, when they separate and pair. In the more remote parts of Scotland the Red Grouse is considered a bird of good omen. By its crowing at dawn, the evil spirits of night are thought to be put to flight, or deprived of their power. The flesh of the Red Grouse is dark, and has a peculiar, bitter flavour, but is held in high estimation.
The PARTRIDGES (Perdices), one of the most numerous groups of the order, are comparatively slenderly built birds, with small heads and unfeathered tarsi. The wings, in which the third or fourth quill exceeds the rest in length, are relatively quite as short and rounded, but not so much arched as those of the Tetraones. The tail, composed of from twelve to sixteen feathers, is always short. The somewhat elongated beak is but slightly raised at its culmen, and compressed at its sides. The tarsus is frequently furnished with one, or occasionally with two spurs. The members of this group are without the warty skin above the eyes possessed by the birds above described; in some species, however, bare patches are observable on those parts, and on the throat. The plumage is smooth, and very similarly coloured in both sexes. These birds inhabit all portions of the eastern hemisphere, except its extreme north, and frequent every variety of locality from the coast to a very considerable height on mountain ranges. Some species prefer cultivated lands, while others are found in forests where they may occasionally be seen perched on the branches of trees. Their food consists of insects, grain, and portions of plants. The nest is a mere hole scratched in the dry mould, generally under the shelter of some bush or tuft of grass. The eggs, from twelve to twenty in number, are hatched in three weeks time; the female sits exceedingly close on her nest during this period, especially during the latter part of incubation, and offers a bold resistance to any enemy seeking to plunder her; but if quietly approached, both she and her eggs may be gently removed, and she will hatch them in confinement, departing with her young to the fields as soon as the latter are able to accompany her. The male takes no part in the labour of incubation, but like all birds that pair, he is attentive to his mate, assists her in defending the brood, and uses many arts to lure intruders from the nest. The young are reared on small insects, larvæ, and the eggs of insects; the parents leading them to the places where these are deposited, and scraping away the mould. Multitudes of ants and larvæ are eaten by young Partridges.
The SNOW PARTRIDGES (Tetraogallus) may be regarded as combining the characteristics of both the Ptarmigans and Partridges. Their body is compactly framed, their neck short, the head small, the wing of moderate size, and slightly pointed at the extremity, its second and third quills being longer than the rest. The gently-rounded tail is of medium length; the beak long, broad, and powerful, and the heavy short foot furnished with a blunt spur. The thick plumage is much developed on the tail-covers; a small patch behind the eye is unfeathered.
THE CASPIAN SNOW PARTRIDGE.
The CASPIAN SNOW PARTRIDGE (Tetraogallus Caspius), a member of the above group, inhabiting Persia, is dark grey upon the head, nape, and upper breast; the plumage on the back is varied grey and reddish yellow, and the rest of the under side grey, the shafts of the feathers are streaked longitudinally with reddish yellow. Two dark lines pass from the corners of the lower mandible to the breast. These lines divide three white patches, one on the throat, and one on each side of the face. The feathers on the upper wing-covers are shaded with black and reddish yellow, with a broad red edge at their outer web; the quills are pure white, as are the belly and feathers of the lower tail-covers. The eye is dark brown, the beak pale horn-grey, and the foot reddish yellow. The length is about twenty-four inches.
