Pearson - 1998 6 Last year we called this location 11 km ENE Bariloche. Then explored the area between the highway and the mouth of the Rio Nirihuao. A lot of dense grass, willows, rosa, chacay, some swampy spots, lots of tuco sign in spite of what must be a high water table. Almost sand dunes in places. Home at nine. November 5- Bariloche. Morning clear, calm, overnight minimum 45°. Picked up traps at 7:30 a.m. The 50 Museum Specials held 5 Oligo and 7 Abro longi. The 50 Shermans held 1 juvenile Oligo, 7 Abro longi, 1 Abro xantho, and 1 Geoxus. Why are we getting so many Geoxus? Released the xantho and the Geoxus, processed all the Oligos and the Abro longis. Almost all of the Oligos had tapeworm cysts in the liver; one of them, the juvenile, had 21 cysts! The liver looked like a bunch of grapes. No mice were fat. All the male longi were breeding, and one of the females pregnant. Total trap success was 22%, success for Oligo 6%; success for Abro longi 14%. Someone broke into our rental car overnight and stole the radio. We seem to have sold the apartment. Heidi Schneiter, the real estate agent, is coming this afternoon to fill us in. At 7 p.m. went to a lecture on the local condors, sponsored by SNAP. Lorenzo Sympson showed lides and told about a nest he had watched, together with a japanese group who were climbers and who set up a remote camera to keep track of what went on. Then the guy from the Buenos Aires Zoo told about the captive breeding program in B.A. and the release in Valle Encantado. Included were videos of the first flight of one or more of the captive-reared birds, and he told about a group of 7 wild condors that came over at the time of the release of the captive-reared ones. Some of the released birds are carrying satellite-tracking radios, I think being managed by someone at Univ. Calif. at Santa Cruz. Lorenzo is going up to California later this month to consult with him and with a television promoter in Oakland. The room was packed, lots of children, complex projection with some failures. Their radio traking traced birds as far north as Alumine and to 80 km south of the Confluencia release site. Patricia Fierro was there; she knows a lady who saw us trapping on Con Con Road and would welcome us trapping on her place nearby. November 6- Bariloche. Morning sunny, calm; banks closed. Overnight minimum 51°; high during day was 73°. Clouded up in middle of the afternoon. Drove down to Eileen and John's tuco study site 10 km N of the outlet of the lake. They and Lisa were out on the study area, which is seriously degraded by the tucos. Burrows everywhere. While we were walking around the area, John saw an unmarked, 2-week-old tuco hiding in the dirt at a plugged burrow. He caught it and took it back to camp to
