Dravo to his Pichi Senfu, skinned, asked about bats at the Estancia (more, 4 Indians said more), Dravo to Vileanigen, asked about bats at the bakery, the store, and the RR station. Everybody except the baker said more, he said they live in cliffs and fly around town at night. Dravo to Estancia Vileanigen, which is a couple of km SE of town. An English-speaking employer (not the administrator Mr Williams) said he had seen some 2 yrs ago in a rocky cliff a couple of km east of the Estancia headquarters. We drove to the site. Good fractured columns, lots of crevices, holes, and caves, but search revealed no bats. Vazcochas and saddles of accumulated vazeochs droppings. Vegetation is bunchgrass and low rounded thornbush. A 1/3rd gramin here is freezing under a thornbush about 5 yards from our tent. Tucoes twang in the grassy flat, sandy, along the stream. They give 3 or 4 very rapid rocky grunts, a 1-second pause, then repeat, not as clear a sound as the Mendezo tucoes make. They sang in the middle of the afternoon, warm & sunny breezy, contagious. Four at same time. Put out about 25 museum species in bunchgrass- thorn-barberia in rocky-cliffy place. Strung a bat net at 8 pm, first star at 9 pm, temp: 8°C, lots of moths and other insects flying. Burned lanterns near net to attract bugs and, hopefully, bats. Saw no bats at dusk. Nov 2 Temp at dawn 5°, cloudy. Tucoes singing at 4:30 AM and a daybreak, catching in net. My traps 5 red-veined alcedon and 1 big phyllothie. One two in trap. Auto's traps held 4 red-veined alcedon, 3 by phyllothies, plus one yellow-nosed alcedon. This one out in
