The most typical member of the Family is _Falco peregrinus_, the almost cosmopolitan Peregrine Falcon, of which the sub-species _F. melanogenys_ and _F. ernesti_, the commonest forms from the Sunda Islands to China and Fiji, are more closely barred below, though not so broadly as _F. cassini_ of the extreme south of America. The colour is slaty-grey above with darker transverse markings, the head and a stripe down each side of the neck being blackish, and the under parts ruddy-white banded with black. Young birds are browner, and are streaked instead of barred. Barely separable is the smaller and darker _F. minor_ of South Africa, the Comoro Islands, and Madagascar, with its larger race _F. punicus_, found from Morocco along both sides of the Mediterranean to Asia Minor. _F. barbarus_, also of the Mediterranean region, but chiefly confined to Africa north of the Niger, and the Soudan, is distinguished by its red nape, brightest in the larger sub-species, _F. babylonicus_, which occurs from Babylonia to North India. The Peregrine Falcon, often erroneously called Goshawk in Scotland–a fact accounting for many British records of the latter–is for its size the most powerful of the Family; and, being one of the "noble" or long-winged forms, is much used in Falconry, wherein the male is termed "Tiercel" and the female "Falcon," as in many other species; while Hunting Hawk, "Blue Hawk," and, for the young, "Red Hawk," are names common to both sexes. Far the most daring of our Birds of prey, the fierceness and courage are especially shewn in defence of its nestlings, both parents dashing angrily at an intruder, and, though rarely touching him, swooping down in unpleasant proximity, as he clambers along some narrow ledge or swings upon his rope. Should, however, the hen-bird, which sits very closely, have fresh eggs, she disappears on leaving them, though her consort flies wildly to and fro at some little distance, reiterating his shrill cry. Exceptionally {179}savage adults may even strike the person; nevertheless, Skuas and certain Owls are decidedly more dangerous, whereas the ordinary Eagle is mild in comparison. The food consists of ducks, guillemots, pigeons, grouse, and partridges, varied by rabbits and so forth; yet, in spite of the undoubted damage caused to game, preservers would be wise to spare a due proportion of individuals in view of their utility in killing off the more weakly and diseased birds. The two to four eggs, usually finely blotched or thickly mottled with rich red on a creamy ground–though one is often paler or yellowish–are deposited in a hollow scraped on some bare or grassy ledge of a sea-girt or inland cliff; but occasionally nests in trees are utilized, or broken ground in northern regions. Two or more sites are often tenanted in turn. Long distances are traversed in search of food, the survivor of a pair mating again marvellously quickly, considering the comparatively scanty supply of partners.
