PEARSON 1951-1952 Rhea Dec 10 Everyone so far agrees that mating is over and that young chicks are already. Sr. Bulger says they go onto the hills to rest, that they lay up to 18 eggs, and that one egg is used as food by the hatching young. He says they are much hunted for plumea and the eggs are sought & sold for food. Jan. 8 Pampa Vizinba. Nature says Rheas come down from hills to feed on pampas at 3 or 4 a.m. Eat little globular fruits of Distichia. Nests in deep. April 15 Shot 2 of a band of 16 feeding almost entirely alfalfa on the Pampa de Copago. The rheas were doing some bucking among themselves. One (duller colored) & with testes about 30x8mm, probably not breeding. Roundwants + tapeworms. Stomach with coarse grass, "bulbs", small plants etc. Feeds largely with coarse vegetable matter. April 20 Pampa de Arriano, 14,500'. While stopped for lunch auto spied a herd of 13 out on the pampa near alfalfas. An hour or so later we took off after them in Bree and approached to less than 100 yards closer than this and they would run, some of them zigzagging with conspicuous dropping of the wings, showing the plumes. Took negatives & stills. Tracks in sand while walking were 16" apart. While running 48" mostly, some 56, and one 60".
