Pearson 1983 102 Stenomyza (cont.) set among bunchgrass and/or gramineae, and the vegetation has been altered: the bunchgrass is much less vigorous and the green between clumps is more turfey. Burrows often open in the middle of clump of bunchgrass. The density of burrows and absence of fresh digging reminds of the colonies of St. peruvianus. all 3 skins show a bright Rufous orange/brown on each side of the nose, and a montecito black close off white below, the white part of the mount looks quite long. The feet seem small. Dec 6 Went at 3pm with Anita, Isabel Christie, and 3 of her crew to another area above Estancia Fortin Chocobuco (2 km S 2 km E Cerro Pintado). This area is a dried- out mallin, no brush whatsoever, scattered bunchgrass, gramineae, and turf closely grazed. The tucos are in a band between closely cropped mallin and levels bunchgrass. Light soil. The vegetation turfier, the bunchgrass without dried tops as nearby. Dozens of open holes and closed holes, many plugged with cut grass stems. The colony where Anita & I watched was about 1/2 acre. At 4:30 set 5 steel traps. Sunny, light breeze, warm. Promptly caught a very young tucos. Before we left at 7:30, Anita and I saw maybe 6 or 8 tenors, most but not all young ones. At one hole, a large as a small one were bearing out at the same time. They held their heads up like an earlier ground squirrel.
