_Caccabis rufa_, the Red-legged or French Partridge, introduced into England from France, and inhabiting Western Europe generally from Belgium and Switzerland to the Balearic Islands, Corsica, Elba, and South Italy, occurs in the Atlantic Islands, but not in Africa. The crown is grey, a black band outlines the throat and reaches past the eyes to the forehead, the upper parts are reddish-grey or brownish, and the tail is partly chestnut. The abdomen is bright buff, the chest grey with black margins to the feathers; chestnut, white, and black stripes adorn the flanks; the bill, feet, and orbits are red. The male is only distinguishable by having rudimentary spurs. _C. saxatilis_, the Greek Partridge, has the chest plain and the flanks without white. It inhabits the Alps, Apennines, Carpathians, Balkans, and Sicilian hills; the eastern race, _C. chukar_, ranging from the Ionian Islands to Aden, Persia, Mongolia, and China, and being naturalized in St. Helena. _C. magna_ of Tibet shews a double gorget of black and reddish. _C. petrosa_, the Barbary Partridge, has a chestnut crown and collar, with white spots on the latter; it occupies North-West Africa, Sardinia, several of the Canary Islands, and Gibraltar. _C. spatzi_ of South Tunis differs slightly. _C. melanocephala_ of South-West Arabia has a black crown, bluish upper parts, flanks marked with black and white, {229}and a black mark down the fore-neck. The members of this genus frequent cultivated country, grassy desert-hills, and scrub-covered ground, up to sixteen thousand feet; they are unsuspicious in quiet parts, but such is not the case in England. They run and fly far and fast, but are exceptionally hard to flush, trusting almost entirely to their feet, and occasionally when hard pressed resorting to trees. The loud note may be syllabled chuk-chuk-chukar-chukar; the food consists of leaves, fruits, seeds and insects; the nest is a scantily-lined excavation, containing from seven to fourteen yellowish-white eggs with reddish specks or blotches. The pugnacious males are used by the Cypriots to attract their wild kindred; but in Britain they have been said–probably in error–to drive away the Common Partridge.
