RHEA LYING DOWN.
The breast of the larger members of the Ostrich Tribe is provided with a large horny plate, on which they support the body when resting.
The Rhea is a native of South America. It is frequently referred to as the South American Ostrich, and also as the Nandu. The resemblance which it bears to the true ostrich is striking, but it may at once be distinguished therefrom by the fact that it has three toes and a feathered head and neck; furthermore, it is smaller in size, and lacks the conspicuous white wing- and tail-plumes. The tail, indeed, as may be seen from the photographs reproduced is wanting. The rhea must be regarded as standing at the head of the flightless members of the Ostrich Tribe. Its wings, though not large enough to raise its heavy body from the ground, are yet of considerable size.
In Buenos Aires rheas are hunted with dogs. If a breeze is blowing, the birds raise one wing, which acts as a sail. This done, they can acquire a speed which makes it absolutely impossible for either dog or horse to come up with them. The only chance of ultimately capturing them is by wearing them out by ceaseless pursuit. A chase of this kind may last an hour and a half. Needless to say, for sport of this kind both horses and dogs must be the best of their kind and in "good form." The natives and Indians hunt them on horseback with the "bolas." The bolas, or balls, used for this purpose consist of two round stones covered with leather, and united by a thong of about 8 feet long. One of these is held in the hand and the other whirled round the head and suddenly released, when both go whirling madly round till they strike the rhea's legs, around which they instantly twist, and the victim is a fast prisoner.
The rhea is in danger of disappearing altogether as a wild bird, owing to the ruthless slaughter which is made upon it for the sake of its feathers. For some years back, Mr. Harting tells us, "the number of birds killed has averaged 400,000 per annum, and, as a consequence, the species has already disappeared from nearly half the territory of the River Plate." On some estates in Argentina the wild birds are driven in and plucked.
Like most of the Ostrich Tribe, the male alone performs the duties of incubation, hatching some twenty eggs at a time, the produce of several different females. There are three different kinds of rhea, but they do not differ much one from another. The young are curiously striped. The egg is very large, of a cream colour, and deeply pitted.
