Pearson - 1993 3
years.
4 November.- Bariloche. Finished ageing xanthorhinus skulls
and delivered them to Ecotono. None of Adrian's group
were present. Temperature mild but overcast,
barometer low. Repaired lights on car and connected
the speedometer cable, which Victor had disconnected!
A satellite photo in color is available in stores. It
covers from Cholila to Volcan Lanin.
5 November.- Aguas Calientes, Chile (near Termas de
Puyheue). Left Bariloche about 9:30. No troubles at
immigration or aduana. The first quila (which was
blooming) was 7.1 km east of the Chilean aduana. Then
lots of bloomed quila to Aguas Calientes. We stopped
at numerous places to look at plants that appeared to
be dead for two years, one year, and even a few still
green and freshly blooming. Could find nothing that
looked like a seed, and no seedlings. Also saw a few
quilas not yet bloomed. Saw no pigeons, no parrots,
no mice. Rain rain. Checked into a cabana at Aguas
Calientes, then went for a walk through a gorgeous wet
forest with quila and other bamboo. Still no
seedlings, no seeds. If it rains year around here,
one could not expect seeds to accumulate without
sprouting, and thus they would not be available to the
mice and birds for a long enough period to allow big
populations to build up.
Our Park Guard friend Nicolas Pacheco is off at
Osorno today, but will be back tomorrow.
6 November.- Aguas Calientes. Rain off and on during the
night. Walked up the forest trail in the morning,
then looked up Park Guard Nicolas Pacheco. He showed
us a place along the road to Antillanca where 1-inch-
tall seedings of quila bamboo were coming up, under a
tangle of cut quila. It was a slope where woodcutters
had messed up the bamboo. Nicolas says that these
seedlings are coming up because this paricular spot
gets sun. He says that these plants bloomed two years
ago: bloomed the first spring/summer, fattened up the
seeds during the next spring/summer, then dropped the
seeds during the autumn/winter, and now are sprouting.
He also says that the mice climb up into the canes and
eat the flowers before the seeds have fallen. Ditto
birds, such as wild pigeons and jilgueros (=Sicalis).
Neither he nor other people reacted when I suggested
parrots might eat the seeds. Nicolas showed us a
video of a mouse up on a quila cane frantically
feeding on seeds/flowers/developing seeds. It was a
fat, long-tailed mouse which he thought was an
Oryzomys. When I commented on how fat it was, he said
it was in winter and the fur might have been wet. And
