In the fifth group are found a queer family of birds with straight slender bills and feet that are furnished with long, sharp claws. These birds are also found in Australia and they have a peculiar habit of laying each of their eggs in a separate hole, then covering each with a large mound, scraped together by the Birds; and the eggs are then left to be hatched by the sun. The Bush-turkeys of Australia and New Guinea also belong to this group. The sixth group comprises our Pheasants, Peacocks, Guinea Fowls, Curassows and Turkeys. The handsomest Birds belonging to the family of domestic Fowls—the Peacocks, Golden Pheasants, etc., are found in this group. THE PARTRIDGES. [Illustration: COMMON GRAY PARTRIDGE.] The Partridges make their home on the ground and never perch in trees except when they are forced to do so. Like the Quail they run with remarkable swiftness; their flight is rapid, but low, and does not extend to long distances. These Birds are very sociable, and live in flocks or coveys composed of the parents and the young of the last brood. They are not migratory, and they seem to attach themselves to certain localities and do not leave unless compelled to. At the time of laying, the mother-bird makes a hole in the earth, which she lines with grass and leaves, and in it deposits her eggs, to the number of twelve or fifteen, and sometimes twenty or more. While she is sitting upon the eggs her mate watches over her and guards her from danger. When the young are hatched, the father-bird devotes himself to the care of his children. He accompanies them in their wanderings; he teaches them to catch grubs, find ants’ eggs, and shows himself as skilful as the mother in guarding them from attacks of their enemies. At the appearance of danger the father utters a cry of alarm, which warns the young ones to hide. Drooping his wings in order to induce the intruder to follow him, he pretends to be unable to fly. At the same time the mother-bird proceeds in another direction and, alighting some distance off, she runs back to her family, and leads them to a place of safety. This is one of the intelligent methods by which the young brood is protected. A few weeks after they are hatched the young Partridges are able to fly, and to provide for their own wants; they do not leave their parents, but continue to live with them until the following spring, when they begin to build nests and plan for their own children. Partridges are of a shy and timid nature, which shows itself in many ways. But this is not surprising when it is remembered how numerous are their foes, for Foxes and Birds of prey make continual havoc among them; the latter especially are particularly dreaded. At the mere sight of one of the Falcon tribe, a Partridge is so overcome with fear as to be almost incapable of concealing itself, and it is not until the dreaded enemy is gone that it regains self-possession.
