Pearson - 1995 17 Limay). They have been marking tucos like mad; numerous colonies out on their flat with many young. John has seen Reithrodon emerge from a burrow from which a tuco had been captured shortly before. He also says that up high some of the sociabilis are living in very bare slopes, not mallines like the type locality. Dissected owl pellets. 5 December.- Bariloche. Sunny warm. Oil change and filter $60. Margarita the janitor had heard on the television that I was an authority on mice, and asked how Hanta Virus was transmitted. She had heard somewhere that it was transmitted through the urine. School children are being told about it and taught to keep their houses clean. Margarita's family lives on the Rio Puelo in Chile, just over the mountains from El Bolson. Nadia Gutmann broght her thesis by. She has a cousin in El Bolson and says that two of the fatalities there were father and daughter who lived in very close quarters with other houses. The mice that were caught there apparently were pickled and sent to Jaime Polop for identification. Nadia says they were Oligoryzomys and Abrothrix longipilis. She also says that a lady at ECOTONO is studyng rosa mosqueta and has found a fungus that attacks the fruits; is hoping that it might serve as a biological control. Drove to Eileen's campsite in the willows to look for Irenomys. Set 14 Sherms just before dark all except 2 up in the willows. Eileen came home with three live juveniles (about 70g) to hold overnight. She fed them bull thistle. Evening calm and warm, clear, full moon. Then looked for mice with the nght vision goggles. One Sherman on the ground in a tangle of branches in which California quail were roosting held an Abrothrix longipilis. Heard barn owl once. 6 December.- Mornig warm, clear. Traps held one Oligoryzomys (on the ground in the same trap as the Abrothrix last night), and another about 4 feet up in a willow. Then visited Eileen's study area across the road. There is a large green grass/clover etc. meadow without tucos (too wet?), then a flat with bunchgrass, green grass, thistle, Senecio, a few chacay trees, and lots of tuco burrows. A few of them were fresh fresh; heard no vocalizations. Eileen and John demonstrated
