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
