including two wild temp. mor 3° colm den. Nov, 17 Dawn colm clear, temp 0°c, Estoria minunthermom -2°. no more bats in net after middle of night [watch hod stopped]. All 8 adult bats from attic were females, from non-preg through almost-volant young. Three males called out side, Tagged 6 females and released them. Two landed in tree, the other dropped/promptly under eaves on both sides of the gable at end end of house. One scurried into the bird well to get in. Processed 15 others including a discarded juvenile Histotus, 70x25x9x16 forwom 29 6.3g. naked. I think we handled at least half of the entire colony. All except one survived something holding overnight in the bat net down to 0°c and were warm enough to fly early in the morning. Drove to El Bolsón and stopped at Sr. Kovac's house. He and his topidermist son were in Buenos Aires, but another son drove me to the farm of another son, a farmer, at Hoyo de [illegible] Efkuyen 12 km south of El Bolsón. He took me to two possible bat farms, but we ended up at a third in Hoyo, an old barn with almsut droppings and good reports from the owner. Droppings fairly large, didn't smell like Tadaris. Temp at dusk (9:20) 12°c, clear, mosquitoes for a short time. Nov. 18 Dawn partly overcast, calm, 7°c. No bats seen during careful watch, and none caught in net. At one of the barns visited yesterday, Kovac had removed a big cluster of bats [like a swarm of bees] a year or more ago. This was 4 km S of the Hoyo's Kovac's quinta. Leonista lorkshur in bloom, apple trees with marble-sized apples. Frosts seem to be a problem, but not as severe as at Folegus. Note that the altitude here is only about 400ft. Saw eucalyptus trees as tall and straight as at [illegible]. Yesterday there was only a few wild roses in bloom, but today lots of them. After breakfast chaked out the "old mill" on the Bracada
