PEARSON 1951-1952 Cenornis April 11 Returned to our living camp site to collect more of this two. Number of fresh droppings about as before. Set 13 two traps. April 12 Fair catch of tucos, but mostly juveniles or small females. Several caught by belly skin or hind feet. Leave these move backwards also. Terrain here is very sandy, one would think too sandy for tuners. Vegetation is primarily Festuca orthophylla with some Tota rigidum. Many feeding holes open under these plants, and pencil-thin stems of rigidum are missing off clearly at these holes. Tails of their tunics [pull] (with difficulty) whereas ferrand don't April 13 More tucos in moving - Despite considerable hunting we have seen none of this species close ground here (or elsewhere). Drove up and over the crests, then down to the pampa between Junin + Chollefoden. The tunics go right up to the edge of the Festuca, in fact sometimes a succession of dirt mounds shows where one struck out for the continental divids, just none went to reach the divids, although only a few hundred yards short. There are scattered droppings down the flanks of Junin, across the Pampa de Tutio, which slopes flatly but steadily up toward the divids, down to the river, coupled where the short-cut road leaves the main road. Lots of droppings; put out traps after lunch. By 4:30 had 5 tucos, no more at dusk. These are all smallish ones, some looking quite Juvenis-ish, others more feminine, as expected hoped. Still can't decide whether they are nutty-rules. The substrate is sandy gravel, vegetation a mixture of Tota rigidum and Festuca and small dwarf bunchgrass (see photo) Moved the tunics here burble. They cut Tota rigidum. April 14 Shot a Juvenis-ish juvenile at 7:30 a.m., and saw fresh droppings at 8.
