Pearson-1989 26 Confluencia. Some fairly new sign of tucos at the usual place 10km NNE of Nahuel Huapi, and at another similar site 1 km farther north. Fraga for supper. November 29 - Bariloche. Weather warm and sunny. Went with Adrian Monjeau to the tuco place along the highway. The first place, our usual trapping site, is 12.6 km by road NNE of Nahuel Huapi, and the second place is 1 km farther north. I am calling them 10km NNE and 11 km NNE. At 6 p.m. we set 11 steel traps on the west side of the road at 10km, 6 at 11km on the east side, and 1 at 11km on the west side of the highway. Several tuco nests were uncovered looking for good sets, plus grass plugs, etc., but no signs of recent digging and no vocalizations. 11km seemed more active and with less digging by hurones/skunks/armadillos,foxes. Just before dusk I set 18 Shermans in the sheep trail (between two fences) at 11km on the east side of the highway. Rather rich bushy, sandy steppe with neneo, Senecio, coiron. Checked the tuco traps before dark and already had 1 adult (by the tail) at 10km and two adults not seriously damaged at 11km. November 30 - 11 km NNE Nahuel Huapi. Night mild, clear. At 2:30 a.m. the 7 tuco traps at 11km had not been touched, but at 7 a.m. a trap right next to the car held a second adult tuco. I was sleeping right next to this (and other burrows) and heard no vocalizations. One burrow at 10km at 9 a.m. had been plugged. Reset the trap, but nothing caught by 10 a.m. Two adult Reithrodons in the 10 km traps, however. The 18 Sher mans held 1 Reithrodon adult, 2 Akodon xanthorhinus, and 3 Bligmodontia (sic). The first ones from the Cullin Manzano massif. They are very short-tailed. Returned to Bariloche at 10:30, built shipping cages, and then Adrian shipped four tucos, 1 Reithrodon, and 2 Bligmodontia to Reig. Gwenn Brewer and her field assistant stopped in. Her ducks in Buenos Aires Province dried up. They have seen rheas slip between the wires of sheep fence. Pedro Pietro, the ex-parkguard from Puerto Blest and now at Lago Bspejo, stoppped in with advice about where to find the strange bamboo at Lago Frias: right along the road at the border with Chile. December 1 - Bariloche. Weather has turned cold and drizzly, with some hail. Adrian and Fraga visited. Bambooood. December 3 - Flew to Buenos Aires. December 4 - Annual meeting of SAREM (Argentine Mammal Society), Fernando Kravetz president. There were about 50 people present, about 20 posters on the walls of the 4th floor of Pabellon II of the Facultad de Ciencias Exactas y Naturales in Nunez, plus symposia and round tables. Kravetz and his group and ex groupies were in evidence, Jaime Polop was there with three posters, Christina Busch with tuco posters, Martha Piantanida with an Akodon growth poster, various Calomys/Akodon in cultivated fields papers. The Primate symposium was attended by a totally different subset of people. Dr. DeCarlo appeared briefly; he is retired and practising medicine. Reig was much in evidence at the business meeting and tried to postpone the
