1968 journal June 29 Chillon Valley, km 60 (Quiver), 4000ft., Dept of Suiza. Drove up the valley and set traps at 5:30 p.m. a heavily-boulderded cactus slope, abundant small fuzzy Cereus and a larger 5-pleated cactus. A few sparse spiny bushes and scattered grass. Saw a few mouse droppings while setting. Lots of good cover and ? food. Night calm & clear 1/8 moon. June 30 Heard barn owl. My traps (3 can and 17 mouse- specials laced with catmeal) held 3 Phyllotis (darwinii quiv) Andy & Bryan caught more. The quirinus was caught by the tail in a snap trap, sluggish. Even after 2 hrs in a can trap with food he didn't fully revive. moved down valley further to km Chillon Valley, km 53, Yungas, 3300ft., Dept of Suiza Walked up rocky-cactus hillside at noon and found large mouse droppings on top of rocks, a possum skull (frequents), and a burrowing owl, mostly insects but a few mice (sawd). We are set to a cemetery up the hill from a village with a church. Lots of stone walls, with pepper trees, shrubs. I set 7 can traps and 7 mouse specials along a wall with vines + pepper trees and shrubs bordering a slightly grassy fallow field. Nearby is a row of hibiscus with lots of hummingbirds. July 1 Night calm, fog came and left twice. Heavy dew. My traps held nothing. Bryan and Andy, setting along walls on the edge of rocks - cactuses caught 2 live Phyllotis & 2 dead. The two dead ones are Darwinii and probably won't get put up. All day wrestling with getting the car operating, thru customs etc. Stayed in Suiza through
