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.
