RED-LEGGED PARTRIDGE. Perdix rabra, Ray. Le Perdrix rouge, From this peculiar and beautiful group the Common Partridge may with great propriety be separated, as their habits and characters vary considerably, the Red-legs being spurred, and according to some authors perching on trees, which the common species never does; and it is also destitute of spurs. Of the Red-legs five distinct species are now recognised, three of which are natives of Kurope: of these the species here represented is the most common, and is, we believe, confined entirely to the Continent and the islands of Guernsey and Jersey. Like the Pheasant, the Red-legged Partridge is now naturalized in the Bri- tish Islands, but it must nevertheless be considered an introduced species, and consequently as not strictly be- longmg to our Fauna; and we much question whether those who have them on their estates have not cause to regret their introduction, for although highly ornamental in their appearance, their flesh is not equal to that of the Common Partridge (Perdiz cinerea), which from its diminutive size and less pugnacious habits is com- pelled to retreat and give place to its more powerful opponent. It is more shy and wary than the common species, and is very difficult to approach, even at the commencement of the shooting-season, a covey being seldom flushed without having run before the dogs for a considerable distance, when they mostly rise out of gun- shot. It is now becoming extremely numerous in many parts of England, particularly Suffolk and the ad- joining counties. Although it does extremely well in preserved manors, arable lands, &c., still it appears to evince a partiality for sterile wastes and heathy grounds. It is very abundant throughout the plains of France and Italy, is rarely found in Switzerland, and scarcely if ever in Germany or Holland. It is very prolific, the female laying from fifteen to eighteen eggs, of an orange yellow freckled all over with markings of a red colour. The young before the second moult have their plumage striated somewhat after the manner of the young of the common species, but by the end of October this colouring is exchanged for the transversely marked plumage of the adult: the old birds of both sexes are so nearly alike in the colouring and markings, that were it not for the blunt spur, which always forms an appendage to the male, it would be difficult to distinguish them. — Its food consists of wheat and other grains, vegetables, insects, &c. Its flesh is whiter and more dry than that of the common species. The male has the forehead grey; crown of the head and whole of the upper surface greyish brown with a tinge of rufous; throat white surrounded by a black band, which dilates upon the chest and the sides of the neck into a number of small black spots on a grey ground ; abdomen and under tail-coverts sandy red ; fea- thers of the flanks grey at their base, to which succeeds a broad transverse band of black, the tips being chestnut red ; outer tail-feathers rufous, the centre ones more grey ; legs, bill, and eyelids red.
