Villa Tacul. All had lots of rosa mosqueta, then various mixtures of bamboo, coihue, arrayan, etc. The Villa Tacul was especially lush with lots of rosa plus very dense grass only slightly grazed by horses. A total of 100 traps out, half Sherman, half MS.
The park guard remembered us from last year, said there were very few mice this year,and still thinks the outbreak might have been due to flowering bamboo (two clumps near his house flowered). Then we camped at a picnic ground on the lake beyond his house. A few wee drizzles at dusk and a few more during the night. Heard no owls but lots of chimangos at this picnic spot. Parrots across the road from the Park Guard, plus a pair of grey-necked geese and some doves there also.
November 26- Drizzle in the morning and most of the day. Overnight minimum in Bariloche was 52°, yesterday's max 65°. Picked up the traps early and returned to Bariloche by 9 a.m. There was an Irenomys in a MS in the grassy glade near bamboo B2 and a baby Oligo in a MS under a rose bush across the road from the parkguard house. In Shermans there were a large Oligo and an Abro olivaceus in theVilla Tacul meadow. The total catch in Shermans was these two plus 5 Abro longipilis; the rest of the catch was in MS traps. Total for the 100 traps was: 1 Irenomys, 1 Abro oliv, 2 Oligoryzomys, and 12 Abro longi. = 16% catch for all species, 2% Oligo, and 12% longipilis. I listed only the big Oligo in my catalog as coming from Villa Tacul, and the olivaceus in my journal, but actually several of the longipilis came from there also. They are maybe 2 km apart. All except the baby Oligo were in breeding condition, none were fat, none had tapeworm cysts in the liver, several had hemorrhagic lungs.
Then Thanksgiving dinner at Alberto's restaurant with Eileen. John, and Lisa. Drizzle stopped in the evening. Max temp during the day was 60°
The Abrothrix olivaceus, caught in the grassy meadow at Villa Tacul was not saved: male, 159x69x22 28g. testis 12, sv 15; liver ok, lungs ok.
November 27- Bariloche. Overnight minimum 48°, afternoon max 62°, sunny and windy.
Got the car safety-inspected ($75, no corrections needed except for buying a fire extinguisher and safety signals to put in the road when you are changing a tire).
November 28- Bariloche. Overnight minimum 46°, afternoon max. 68°. Clear and windy. To a Coro Navideno concert in the evening in a gymnasium. Sat next to Adam Hajduc. He is going up to Lago Tromen on an appraisal trip for the Province of Neuquen concerning a new Provincial Park there (west of Chos Malal). Apparently the Province has contracted for SNAP to do a survey. Iglesias and maybe Christie will be going soon also.
November 29- Bariloche. Overnight minimum 45°. Sunny, breezy all day.
