Taking the whole world over, the families of the goshawks and sparrow-hawks, which practically merge into one another, are very extensive, comprising more than thirty species, many of which could without doubt be pressed into the service of man. Only three of these have, however, commonly been trained.
Goshawk (Astur palumbarius)
Female—Length, 22 to 24 inches; wing, 12½ to 13½; tail, 10 to 12; tarsus, about 3.5. Male—Length, 19½ to 21½ inches; wing, 10¼ to 12½; tail, 9 to 10; tarsus, about 3.
Females and young males have the upper plumage a dull liver brown, broadly margined and barred with much lighter brown; the tail, barred with five broad bands, dark brown. The under surface of the tail is pale whitish grey, with five bands of dark brownish grey. The rest of the under plumage is pale or rusty cream colour, tinted more or less faintly with salmon pink, and streaked irregularly on the breast and flanks with longitudinal patches or splashes of dark brown. The cere and legs are greenish yellow. The eyes are very light, and clear yellowish grey, and so bright that the Greeks gave to this hawk the name of
ἁστερἱας ἱερἁξ, the star-eyed hawk. Adult males have a decided grey tint on the upper and under plumage. At the first moult both sexes change the longitudinal streaks on the breast, thighs, and flanks into more or less irregular bars of dark greyish brown; and as they grow older the bars usually become narrower and more regular. The tail is now barred on both surfaces with four broad bands of dark brown or grey. The cere, legs, and feet become yellow; and the eyes change to a deeper yellow, and ultimately to deeper and darker orange.
Goshawks vary greatly in size and strength. Those which are imported from Norway are often exceptionally big and strong, while the specimens from Germany and Central Europe have a reputation for weakness. Although this hawk formerly bred commonly in England, it is now practically extinct; but some nests are still annually found in France.
The list of quarry at which the goshawk may be flown is very large, including, for the British islands, hares, rabbits, stoats, weasels, squirrels, and rats; herons and wild ducks—flown as they rise—pheasants, partridges, landrails, water-hens, jays, and an occasional magpie or wood-pigeon. In fact, any moderate-sized bird which gets up close in front of a goshawk must bustle himself if he intends to escape the first quick dash of this impetuous and greedy pursuer.
In India and other tropical countries the female “goss” will fly, with a good start, at crows, neophrons, minas, florikin, francolin, jungle-fowl, and even such big birds as kites, geese, cranes, and pea-fowl. Even in England she was formerly flown with success at cranes, wild geese, and other large water-fowl; and the old books contain elaborate directions as to stalking these birds “with grey goshawk on hand.” In some parts of Asia goshawks are said to have been flown at ravine deer and bustard; but this would probably be with some assistance from dogs.
The male goshawk, much smaller in size than his sisters, is less valuable to the sportsman, but is usually accounted rather swifter on the wing. The best specimens will catch a partridge in fair flight; and most of them, with a tolerably good start, will overtake a pheasant. A very strong male will sometimes catch and hold a full-grown rabbit, and the others may be expected to kill half-grown rabbits and leverets, if kept to such quarry. Landrails and water-hens make a more or less easy flight. Jays and magpies may sometimes be taken, as well as blackbirds. Rats, weasels, squirrels, and “such small deer” are, of course, available. Occasional specimens of the male goshawk are extraordinarily fast and strong. Colonel Delmé Radcliffe had one which actually killed grouse in Scotland, and another which took storks and geese in India, as well as partridges.
