Pearson - 1988 45_25 live Ako longi, 1 live Geoxus, and 1 dead Oryzomys. Returned to Bariloche and processed mice. Day sunny and calm. December 1- The captive female Geoxus ate 10g of Oryzomys carcass in 20 hrs. The male, after having mouse carcass but no water overnight, drank immediately when offered water. Drove up Cerro Otto with Fraga and marked still more leaves. Sunny, warm, and calm. Photos 4x5 of the two marked clumps of bamboo. December 2- Bariloche. Clear, sunny, calm. Drove up Cerro Lopez with Anita and Fraga to the end of the road (a few snowdrifts), then hiked up to the Refugio at 1600m, where there was lots of snow. The awful road goes through dombeyi, a few nires, then lenga. Bamboo goes fairly high but not to the lenga achaparrada. Found no Buneomys or other droppings up in the rocky-snow near the refugio; one jaw of an Akodon longipilis. Set 5 Shermans in lenga achaparada on our way in, then picked them up 5 hrs later, nothing. The captive Geoxus each ate 17 g of mouse carcass in 24 hrs. December 3- Bariloche. Sunny, warm. Christie came late last night with comments on Buneomys ms. He quotes Conrad Bailey of San Ramon as saying that the current drought is becoming serious and that animals are dying in some parts of the Province. The captive male Geoxus ate 19g of Akodon longi carcass, and the female ate 12 g or Oryzomys carcass (all there was except some skin). They eat the smaller bones such as ribs but leave veretebrae and pelvis. December 4- Bariloche. Morning mostly cloudy, not cold. Geoxus ate lamb and beef, a little apple. Found a wild bamboo plant along a stream on the next road west of the University (towards the pine forest). Started measuring growth of leaves and interleaf distances on the bamboo plant in the front yard next door to our apartment. December 5- Bariloche. Went to the big cave at Cerro Leones with Patricia Fierro and Rosendo Fraga. There is a hummingbird nest (Oreotrochilus) well inside the cave, quite dark, about 12 feet up. The female? was incubating. She flew off when we approached, but returned several times during a half- hour while Patricia was taking flash photos. No young visible. The only "hummingbird flowers" seen nearby were a couple of bloomingh Notro 150m away and a big patch of Notro about a half-mile away. We picked up about a gallon of owl pellets at the usual spots along the cliff, but didn't make a very complete collection. The captive female Geoxus gave birth to 4 young. December 6- To Lago Perito Moreno on the Llao Llao Peninsula in the afternoon. Day mostly cloudy, some drizzle at Lago Moreno while we set traps in bamboo/coihue/cipres forest along the road back to the campsites. Anita put 21 Sher mans and 21 Museum Specials and I put 21 Sher mans and 24 MS. We also put some traps along a side road, the first one to the right after passing the Fundacion Bariloche center: Anita 7 traps and I 4. Almost all of the access roads have now been ditched or posts planted
