sound, tu - co pause tu - co pause etc, frequently ending with a tuc tuc tuc tuc. Heard it after daybreak but not during sunny part of day. At an abandoned, crumbling puente yesterday found a Todarida between a ceiling beam and a wall. Since we were lost all day, I guess lengthily at 10 km N [illegible] Amila's traps held one mouse, in scrub along road, no grava. Battery ran down, motor barely turned over. Waited about an hour for warmer weather, then it caught. Drove to Orajera, obtained, then drove to Monte Covan. Picked up 3 hitchhikers on the way. Saw a pair of Bolichetus, lots of guinea pigs, one small ch arnoldella (not the mulita and not the pichi), many caracaras (verloft because of the telephone poles, which are in short supply in the monte). The guanacos should have some big snake + raptor/predators. Drove south to Orajera, then along the railroad to Monte Covan (lunch) then to San Rafael for lubrication and new battery, [illegible] orjara then towards El Somiedo but stopped at the RR Station Los Parlamentes, which is 60 km NNE Malargue and, according to the station master, 1,170 m altitude. It is at the edge of a huge pampa with almost pure juncosa, very sandy soil; north of the station is sago brush. Put about 12 museum speicle around piles of quebrado RR ties in the juncosa, and strung a hot net in the courtyard of the station house. Wind moderate stopped before dusk, returned somewhat during nights, [illegible] set two tuc's other tuffs in the fence. Oct. 24 Caught 6 Todarida in the net, 5 of them before 9:30 p.m. are ant star lizards in the mouse traps, as two tucos. Station master calls them tuldugues and decides their call tuc tuc. He seems to be a good informant. Says there are lots in the attic winter and
