Wherever there are deer-forests in Scotland, even to-day,--but nowhere else in Great Britain--may you count on seeing the golden-eagle. And it is a sight to gladden the eyes. Its great size, broad wings, and wide-spread, upturned, primaries, are unmistakable, when seen on the wing--and it is rarely that you will see it else. Those who cannot contrive to visit the haunts of the golden-eagle may find ample compensation in watching the flight of the common buzzard in Wales, the Devonian peninsula, and the Lake District. Though time was when it might be seen all over England, wherever woods abounded. Its flight, when hunting, strikes one as somewhat slow and heavy. In fine weather, however, as if for the mere delight of the exercise, it will mount heaven-wards in great sweeping spirals, holding its broad wings almost horizontally, and spread so that the primaries stand widely apart for half their length, and in this joyous movement they will remain aloft for hours on end. But for the untiring efforts of the Royal Society for the Protection of Birds, none of our larger birds of prey--save, perhaps, the golden eagle, which is carefully cherished in the deer-forests--would now be left to us. The case of our harriers seemed hopeless. But, thanks to a zealous protection, a remnant remains. The harriers are in many ways extremely interesting birds. In appearance, when closely examined, they present one remarkable feature. And this is found in the curious arrangement of the feathers of the face which radiate from the eye as a centre, as in the owls, to form a "facial disc." They are all large birds, of slender build, and have a habit of flying close to the ground with their long, slender legs dangling, crossing and re-crossing the same area till they are sure they have examined it thoroughly. Frogs, eggs, small birds, and voles form their principal food. Every now and again they will rise and circle round at a considerable height, seeking a new feeding ground. The marsh-harrier is our largest harrier, and has rounded wings, and slower wing-beats than the others, from which it is further readily distinguished by its chocolate brown coloration, cream-coloured head, and grey tail and secondaries, which contrast strongly with the black primaries. The hen-harrier breeds only in the Orkneys and the Outer Hebrides. It is distinguished by its grey coloration and pure white rump-patch. Montagu's harrier is a somewhat smaller bird, and has black bars on the secondaries. In flight it is more graceful and buoyant than its relatives, and this is accomplished by three or four wing-beats, alternating with a long glide on half-raised pinions. It, again, nests annually in East Anglia, thanks to protection.
