For birds note that there was nothing higher than 3 1/2 feet of 3 feet on the ichn area (not on the tolo or T. laburiae areas). Summary of plants on ichn area: no. of birdholes per plant station 0.34; birdholes per mouse station 0.61; birdholes per no-mouse station 0.09. Profile: 1st half meter 81.0% of board excluded; 2nd half meter 4.1%; 2nd meter 0.03%, Hoof sampler % coverage 50.0%; % coverage at mouse stations 54.6%; % coverage at no-mouse stations 48.0% Nov. 3 Tarata, I put 17 museum species and 1 large shrew in the big rocks south of town and along a stone wall with scattered bushes at the edge of a clover alfalfa field it drank. Benson put 20 MS along a wall at the edge of a young corn field. Nov. 4 Night clear, light frost on clover leaves. Combined catch was 13 Ph. magister and 3 Akodon boliviensis. Below the level of the big rocks, every mouse on the entire hillside surely lives in a terrace wall. Linnell of Benson's mice came from about 100 yds of wall and surely don't include all of them, let's say 1/2 phyllostis per 100 yds of walls = hundreds or thousands on that terraced hillside. at 3 PM drove up to the acequias camp with Benson and I put out 40 small shrews, mostly along road walks, some in thick brush in a gulley across the road. He put out +/- 50 long shrews and maybe 30 museum species. Clear. Nov. 5 Night clear + calm, breeze at about 4:30 a.m. No deer puddles. My traps had 7 phyllostis (mostly darwin but at least 1 magister) and 2 Bolomys berkeshii - all phyllostis put up except 1 darwin escape.
