Pearson - 1997 the Familia Tierno in Villa Angostura (Maria Tierno, tel 94-499). He says there are very few chimangos around town because they have been poisoned by eating poisoned carcasses of mice. 16 November- Cleared up overnight. Morning clear and sunny. Max-min all last week while we were away was 42-55. Werner says it was an unusually warm winter and spring: lots of rain, a warm spell, then cold and some snow, then more rain which caused floods, etc. He says the winter before was mild also. Went out to Flueck's log cabin above Lago Gutierrez. Sunny, clear. At 11 a.m. put out 24 Museum Specials in cipres/cohue forest, sort of scrubby along the roads, with a few rosa, Mutisia, etc. The oldest coihues have big lowdown branches, so probably grew in open fields. Picked up the traps at 3:30; one youngish Oligoryzomys male just coming into breeding condition. Adrian Monjeau came by at 6 p.m. He had trapped at Rio Turbio, across Lago Puelo, with 90% trap success. Almost all Oligoryzomys. This is a low pass into Chile. Several people have told him about mice marching single file through the woods. Because of President Clinton's impending visit to Llaio Llao a few weeks ago, he was called to consult on the abundance of mice on the golf course there. The exterminators that they had hired were overwhelmed. I didn't hear anything quantitative. I ask everyone about the abundance of predators, but nobody is impressed with large numbers of hawks, ownls, chimangos, etc. Maybe they all went to Chile a couple of years ago for the bamboo bloom and never came back. And no one knows of a bamboo bloom here in Argentina. 17 November.- Bariloche. Sunny, up to 70*. Talked with Nadia Guthman. She had trapped at the city dump; she saw (trapped?) Reithrodon, Mus, and Oligo. Not a plant in sight, all plastic, old cars, etc. Someone told her recently that there were a lot of coihue seedlings (Nothofagus dombevi) this year. Maybe this is a mast year, as in New Zealand? Then to Parques to deliver some stuff, and tried to get monthly weather records for the past 2 years. No luck. At this point it seems that the bamboo has
