P. PEARSON 1955 strewalls or boulders or other shelter for long-tailed pheasants, but saw one mouse (aboron?) while setting traps. Sharply eroding intermittent stream. Expected to find tinamous, but saw + heard none. Many flechets around, saw 2 capulineras Left. 9 EAR Light frost. 1 1/2 box of type bird 3 Aborona bolivensis and 1 Hegeteromyx dreiller. Heard Mothura; shot duck. Drove to Oruro. Toda disappears before Oruro and one crosses a flat salty? Pampa. Saw one band of vicunas on this Pampa, plus digging of two or armadillos in one place. Near the airport about 2 miles east of Oruro is a half-mile strip ridged with two diggings. Big earth mounds, no sign of territories. While watching them heard some guttural sounds, but no bubblings when travelled across the area. Shot one (4166). Only vegetation dry 1/2 inch. The road to Cochabamba climbs up into toda-rich something like Tinopolis, then rich, then a Festuca-like bunch grass, then open ground with dwarf forbs and grasses plus a few rich. A few small gastor birds. A pass at 14,500 ft. Camped in rather open rich at 14,000 ft. and set 1 box of traps in the only available rocky place and along an abandoned wall. Saw aburona? droppings. Not much agriculture near Oruro, but plowing + planting at about the 13,000 ft. level. The Bolivian villages seem almost deserted compared to Peru; few people. Maybe result of Chaco war?
