Pearson - 1993 13 Shermans and 15 MS alternating across the mimas flats, many of the sets at cola de pichi plants, beginning up on the photo hill, then running across the mima flats through mustard, small seeding grases, etc. Then put 8 Shermans and 11 MS across the road and west of the pipeline; much mustard. Some Reithrodon droppings. Anita and Peg ran their traps between 7 and 9 p.m. and Anita had 1 Eligmodontia, 1 Ako xantho, and 1 big Phyllotis, all before dusk. 26 November- Night calm, clear, almost full moon, heavy frost on the windshield. Water trickling down the dry wash and disappearing just before camp. It disappeared later in the morning. Tucos called at least once between 10 p.m. and 3:15 a.m.; then a tuco called at 3:15, two of them at 5:45; and two of them a few times later in the morning. Traps as follows: Anita had 3 live Eligmo in Shermans and 3 Eligmo, 1 Ako xantho, 1 Reithrodon, and 1 wren in snap traps. Peg had 1 Ako sp. dead, 1 Phyllotis live, and 2 Eligmo alive. I had nothing in the 6 traps on the hillside, but in the other line 5 Akodon sp. and 1 live Reithrodon (young). Picked up the traps at about noon. Anita had 1 Ako xantho, 1 Eligmo, and 1 earth creeper. Diurnal Eligmo! Peg had nothing. I had nothing in the 6 hillside traps, but 5 Ako sp. in the the mustard and 1 more Reithro (young); all in snap traps. Note diurnal Reithrodon. The Akodon sp., mostly caught in the denser vegetation of the mimas area, are quite variable in size, frequently hispid, small ears, no white chin spot, and no rusty color on nose feet and tail. After skinning drove to Comallo, weather hot, Then west to the curve at the bottom of a grade, gate on the north side of the road and a dirt road off to the south. Drove back this road about a mile and camped. Three rheas in the mallin. This is still east of the Campode Fistuladas de INTA. A gaucho who came by after we had set up traps says that we are on Campo General Roca. Typical bunchgrass/neneo on the edge of a mallin (dry) with some juncus. 27 November- Almost full moon. Night started out clear, then miostly cloudy, then clear at dawn. No frost. The habitat here is typical of between the top of the Comallo grade and INTA: a mix of bunchgrass and neneo, with some Senecio, a few Adesmia, no Sapium, no Acaena, a few mat cacti in flower, but low species diversity. My line, which had skirted the dry mallin and then cimbed up the hill amid spiney bunch grass
