"The male," says Audubon, "is seen perched on a fence, stake, or on the low branch of a tree, standing nearly in the same position for hours together, and calling, 'Ah! Bob White,' at every interval of a few minutes. Should he hear the note of a female, he sails directly towards the spot whence it proceeded. Several males may be heard from the different parts of a field, challenging each other, and should they meet on the ground they fight with great courage and obstinacy until the conqueror drives off his antagonist to another field." About the beginning of May the female proceeds to build her nest; this is placed on the ground, close to a tuft of grass, and partly sunk in the earth: it is formed of leaves and fine dry grass, is of a circular form, and covered above, with an opening at the side. The eggs are of a pure white, and rather sharp at the smaller end. Both parents assist in hatching the eggs. When the young are freed from the shell they leave the nest, and are led in search of food by their mother, who shelters them with most assiduous care. If danger threatens, she throws herself across the path of the intruder, beating the ground with her wings as if severely wounded, and uttering notes of alarm to decoy the stranger into pursuit of herself, and give warning to her young to conceal themselves in the high grass till the danger is past, when, having allured her pursuer to a distance, she returns, and leads them safe home. The American Partridge usually rears only one brood in the year, but should this be destroyed she immediately prepares another nest, and even should mischance befall this also, a third batch of eggs is laid. This Partridge has been occasionally employed to hatch the eggs of the Domestic Hen. [Illustration: THE VIRGINIAN PARTRIDGE (_Ortyx Virginianus_). ONE-HALF NATURAL SIZE.] "A friend of mine," says Wilson, "informs me, that of several hens' eggs, which he substituted for those of the Partridge, she brought out the whole; and that for several weeks he occasionally surprised her in various parts of the plantations, with her broods of chickens, on which occasions she exhibited much alarm, and practised her usual manœuvres for their preservation. Even after they were considerably grown and larger than the Partridge herself; she continued to lead them about; but though their notes or call were those of common chickens, their manners had all the shyness, timidity, and alarm of young Partridges: they ran with great rapidity, and squatted in the grass exactly after the manner of the Partridge. Soon after this they disappeared, having probably been destroyed."
