1973 ATRP. several hours in the morning running. Early rain sent us into the tent, but then it got better, and looked like a cold night ahead. Saturday, March 17, Challapata. Cold last night, but not bad headache, so I'm feeling much better. OP coughing with some kind of allergy. More trail and lizard watching. Dave went upstream and brought back a duck and two miscarhos for supper. We have been working on the dried dam stem, but rapidly getting tired of it. Sunday, March 18, Challapata OP coughed most of last night. I'd and Dave spent the work, part of the morning with transistors and tools and lizards. I watched my area out by the corral. In mid-morning OP and I drove up to Capazo. In the store we got some candy, mejoral, bread, and sugar. They had no meat for sale, and no knitted things. On the way up to Capazo we saw lots of ringoals in the rocky canyon. Then when the canyon opens into the plaza there was a built-up road bed along a steep place, and we saw more than 6 guinea ducks and 5 Phyllotis boliviensis feeding there at one tie. OP shot some frogs for the museum. Coming down the canyon we spotted a trio of Limamotis along the stream. It seems to be the reproductive season for archenoids - lots of very young birds in the herds.
