Pearson - 1993 4 if it were fat, why was it feeding so frantically in the wild while being filmed? He has been keeping some records of the number of mice brought in by the two cats at his house (which is not particularly close to a lot of dead bamboo). Last April and May the cats were catching lots of Akodon olivaceus, A. longipilis, and Oryzomys. On one day they brought in 18 mice! And they frequently brought in more than 10. When asked about raptors and owls, he said there were lots of barn owls, foxes, and guinas (sall wildcats). When asked what happened to all the mice in the wild, he said that the winter killed them. More than 50 mice drowned in the outdoors hot pool on each of three or more successive days. In any event, we think we can detect at least three cohorts of bloomed quila: one with the inflorescenses fallen and presumably having dropped their seeds; another with inflorescences present and with black "seeds" containing a milky sap; and third, plants still with quite a few green leaves and the seeds not at all developed. In addition there are still a few quila plants that have not bloomed at all. In any event, with three annual cohorts of bloom, and with mice feeding on unripened seeds before they fall as well as after they fall, there is plenty of time for a ratada to develop. The surprising thing is that there are not mice everywhere right now. We saw none whatsoever; nor did we see wild pigeons or parrots. Nicolas said they came into his storage shed and ate plastic, and into the office and nibbled on papers. Left Termas de Puyehue for Bariloche about 1 p.m. Stopped at the pass to pick up the traps we left yesterday. Nothing in my three Shermans, but Anita in four Shermans had 2 big Chelemys. Released them. There were good earth cores lying around, and no tuco- tucos, so Chelemys must be able to make them. 7 November- Bariloche. Windy, mostly clear. Drove out to our bamboo at La Veranada. The road is wider than ever...but not paved. People have been cutting dead nires for firewood, but not live ones. Stumps recently cut, 4 to 8 inches in diameter, have 30 to 40 growth rings; they may have died several years ago. The lengas on the hillside west of the bamboo have more dead tops than ever. Our mouse-trapping grid is a jungle of bamboo, nires, fallen branches and trunks, cacho de cabra, etc. The lengas and nire leaves are well out. There is digging by tucos and Chelemys everywhere, with lots of earth cores. Heard no tucos.
