Pearson - 1994 14 under study. Horses and mules on their study area, a lone guanaco on their side of the road nearer the lake, but they say they have seen it on their area. Their area is not heavily grazed. Saw three hares there, lots of Reithrodon droppngs. John has seen a tuco and a Reithrodon appear at the mouth of the same burrow. They say they hear lots of vocalizing, but we heard none. Things were slow, perhaps because it was cool and cloudy. Picked up five hawk/owl pellets under the cliffs behind their campsite: two of them nothing but rabbit fur, one with rabbit fur and an adult hare palate with teeth, one with one Abrothrix longipilis, and one with one Abrothrix xanthorhinus. December 5- Bariloche. Partly cloudy. Dinner with Rapoports and Monjeaus. December 6- Stopped at Estancia Primavera to see Lorenzo Sympson about owl pellets. He has only a few from Bubo, lots from Tyto, but they aren't ready to turn over to me yet; they need labelling! He says things at Primavera are lush and green this spring, the river quite high, too high for good fishing except at a few places. Then drove to Paso Cordoba, road OK. Altimeter read 4400 ft at the pass, was 2750 at Bariloche. We saw no tuco sign along the road, nor at the pass, but when we got out of the car and walked through the scrub, there were lots of old weathered diggings. Set 11 steel traps in good tunnels 2-3 p.m. to the left of the road right at the summit. The most active places seemed to be at Adesmia bushes. The commonest plants were Acaena, Adesmia, neneo, bunchgrass, Rumex, and Senecio ; 80% ground cover. Light soil, some stones. Then set 2 more at 4 p.m. on the right side of the road. Heard no vocalizations. There is some bamboo in the lenga forest near the top. Lots of red deer tracks, four condors at the top. Checked traps at 5 p.m.; nothing. Anita put out 10 Shermans in scrub along the tuco line. One tuco at 8 p.m., looks like haigi, caught by one foot. It ate grass and Senecio immediately. Another trap stuffed with dirt. Cloudy, not windy. December 7 - Paso Cordoba. Heard horned owl during the night. Tuco traps held one Geoxus, partly eaten, and one other tuco trap buried. Lots of deer tracks.
