P. PEARSON 1951 Day was sunny until approaching Coeur d'Alene, then ran into a wet hail (3 p.m.). Home again 6 Temp. in late afternoon between 35 + 40 with light sprinkle-hails. Frogs calling in evening, and saw 2-rink tadpoles. Went up to mine tunnel in evening to look for birds but none there. Heard no thrushes, only seed snipes and the gull-like cry of [illegible] a black-white phoebe flying upstream in the dark. Dec 13 Minimum 27° at 8:30 a.m. It was 45°; cloudy, very faint drizzle, humidity 78%. Puddle with frogs 5 ½°. Cloudy all day with drizzle, hail, rain, and snow. Snow quite steady from 3:30 to 8:30. Went for walk for 2 hrs. after breakfast, mostly S.W. Ground from recent rain was good for tracking but saw very few winter tracks, no thrushes or rhea tracks. Saw only one herd of vicuna. Day for liberating and recapturing animals, but found none. In afternoon set steel & snail traps in Canyon Mine & Cupola Mine hoping to get abrocoma. On the steep walls of the Canyon mine were several accumulations of bird droppings - probably resulting from night roosting. Looked for thrushes' nests on the gravelly stone ridge above Canyon Mine but found none. Frogs singing after dark, air ½° C. One puddle with 3410 was 4°, another with 3411 was 6°. At 8:30 went up to Canyon Mine to look for roosting birds. A small finch-sized bird escaped from a tunnel on the way. In the canyon shot one tyrant 3412 roosting on one of the pedestals of droppings.
