November 6 - Bariloche. Morning sunny, calm; banks closed. Overnight clouded up, high middle of the sky was 73 degrees. 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 be x-rayed. November 5 - Bariloche. Morning clear, calm; overnight minimum 42 degrees. Picked up trips at 7:30 a.m. The 50 Museum Species held 2 Oligos and 7 Abro longis. The 50 Spermans held 1 juvenile Oligo, 7 Abro longis, 1 Abro xantho, and 1 Geoxus. Why are we getting so many Geoxus? Released all 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 to eat the females. All the male longis were breeding and one of the males was pregnant. Total trip success was 22%, success for Oligo longis 44%. Abro longis 14%. Someone broke into our rental car overnight and stole the radio. We seem to have sold the apartment. Heidi Schmetter, 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 Simpson showed slides 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 they went on to Buenos Aires Zoo to talk 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. Their radio tracking traced birds as far north as Aluminé and to 80 km south of the Confluencia release site. Patricia Fierro was there; she knows a lady who saw us trapping on Coo Con Road and would welcome us trapping on her place nearby.
