far, so not every species is responding to the good conditions-whatever they may have been.
At 6:30 put traps up on Cerro Otto along the meadow and down into the lenga forest. The lengas are leafed out, oodles of bamboo, amancays. Not much else except lush ungrazed grass and dandelions in the meadow. We each put 11 MS and 35 Shermans. Started to drizzle as we finished.
26 November- Got up at 6 to run the traps, and just then it started to snow heavily in Bariloche, huge flakes. But stopped after a half hour; almost no snow remained. So we went up Cerro Otto to pick up traps, but there was 1 to 2 inches of sticky snow on everything, no hope of finding all of our traps. The first 6 traps had 1 Abro longi, 1 Auliscomys, 1 Geoxus partly eaten.
It was still drizzly-snowy in Bariloche at 9 a.m. Our friend at the Fax store has a house at the base of the San Pedro Peninsula, A month or so ago he had colilargos (Oligoryzomys) everywhere on the waterfront. He says there were lots of bamboos flowering, but no specifics, and that the mice eat the seeds, get thirsty, and go to the beach to drink. Same old story.
At 2:30 went back up Cerro Otto and picked up traps. There was less snow than this morning, but still a hassle to find them, plus bamboo canes bent down by the snow everywhich way. The catch (24 hours) in 22 Museum Specials was 1 Geoxus, 1 Oligo, 1 Aulisco, and 5 Abro longi. The catch in 71 Shermans was 13 Abro longipilis and 2 Oligos. Adding in the three mice from this morning, the total catch was 2 Geoxus, 3 Oligo, 2 Auliscomys, and 19 Abro longipilis in 93 traps. Two of the longipilis were 13-gram juveniles (identification not certain, maybe Aulisco?). [=28% trap success for all species, 3,2% for Olligos.]
It started to snow lightly while we were picking up traps, and by the time we return3ed to Bariloche it was snowing heavily, big wet flakes, as heavy a snow as I have seen. Temperature at the time 40. But in Bariloche it didnt stay on the ground.
A gal from Ecotono came by to talk about her project, which is putting up fake bird nests with
