at 7 p.m. (cloudy + cold) we string 3 nets across the front of the garage. Stood watch until 9:30. Saw insects flying and numerous bats flying. One & caught in net before we left at 9:30. Temp. in Bariloko at 10 p.m. was 9 1/2 °C. Oct-31 morning partly cloudy. Temp. at 8:30 AM was 10 1/2 °C. Fourteen & mystics in the nets. The local caretakers (Paulo + Antonio and spouses) say that there were more bats in the net at 11:00 p.m. that they were escaping, and so they killed the remainder. None visibly pregnant; none fat; all with full stomachs. Three full stomachs together weighed 2.2 g. Left about 2 p.m., drove through Bariloko then turned Pilearijen. The RR station at Mirihuan is near a deep narrow canyon with an arched wooden bridge. Too many Sunday picnickers and a soccer game to stretch nets. (Station master not there either). Drove to the next station, through bunchgrass and "pinion- juniper," and stopped there. Station surrounded by willows + poplars, good cliffs nearby, a shallow lake of several acres with ducks, lorburinas, [illegible] reedwips, etc. Nobody around. I put out about 20 traps in bunchgrass-rock-bushes and a few among railroad ties. A few small, all-yellow calceolarias blooming on the knoll where my traps are. Found one with nibbled lips, partly healed. Evening windy. One net across end of lake. Night was clear without wind, but overcast at dawn. Nothing in nets. Traps held 2 Phyllosotis and 2 red-bushed long-nosed shadon, Temp at 7 a.m. was 6°C. Willows and greybirds just leafing out; a robin (Turdus feldkandi) feeding fledgling. This station on the RR is Lento Mexico, 25 km ENE Bariloko, no mice in the calceolaria traps.
