Journal 52 19 mi. W Cheqiuas, 8500 ft., Depto Ancash, Peru There are 3 live mice to take chromosomes from. Ray caught 1 dead Phyllotis andinus. This area may suffer from generally low fertility. Goats gnaze here very often & the vegetation is probably minimal. 7:45 am We are now headed for Lake Conacocha. 25 mi S Huaras, 12500 ft., Depto Ancash, Peru. We passed Lago de Conacocha and kept driving. The altitude there was 4000 meters. We had been in the puna grassland with idlu grass (brunch gross). As we went on towards Huaras the grosses got a little taller. We were looking for Tinnamou in the grassland and found lots of other birds, like Musisaxicola, Frigillus, Mountain Caracara, Cinelodies, and various small things. At a place near here we stopped and looked around. D. Koford shot a Cneolodites + Ray shot a small finch of some sort. D. Koford found a freshly dead Tinnamou chick, and nest with shells + the scocal cores of the adults. 2:30 p.m. It is raining slightly and the wind is up. We are in the Puna grassland. There are snow-covered peaks not far from here. The stream is a clayish gray color, and the ground around it marshy. At 1:15 pm, shortly after our arrival here I injected the three live Phyllotis andinus we collected
