Pearson-1992 7 grazed by cows. Ran out of bait before I got all the way around the island, which is about 200m long and 50 m wide, with a few "entrances" into the quila. The last trap was in the hollow trunk of a live arayan tree about 3 ft. in diameter. Even Nicolas thought it was a big one. Then walked home to Nico's house. Drizzle most of the day. This locality is 2.4 km by road (North) toward Termas de Puyehue from the hosteria at Aguas Calientes; altitude about 440m (altitude from Nicolas). November 11- Aguas Calientes, Chile. Morning clear, no clouds, mild temp. Nicolas says they frequently get 4000 mm of rain per year. My line around the edge of the island of dead quila, 39 traps, caught 1 Akodon olivaceus breeding male tagged 825, and 1 Akodon longipilis open vagina tagged 826. One of the two was caught at the base of a very dead clump of quila that presumably had bloomed earlier than the rest of the "dead" quila (which is not really dead because most of it has a few green leaves and it is presumably still ripening its seeds). I then filled in a blank in the trap line with numbers 36a- 36f, and completed the "surround" of the island with 5 more traps. Total number of traps 50. Traps 36e and 36d are at the base of two additional old dead clumps of quila. No sprouts visible, but the dead culms might be several years dead. We are seeing numerous Araucarian pigeons. The 120 traps (60 Shermans plus 40 steel-based rat traps) set by Milton and Fredy and the 34 Shermans set by Anita caught only 3 Akodon olivaceus and 2 Ako longipilis. Beautiful mixed forest habitat bordering living quila. Nothing in my cage trap along the road at their area. This is 4.7 km NE of the road junction at Termas de Puyehue. Walked with Milton through a lovely woodsy trail in the park at Aguas Calientes. Big arayanes, lots of moss and lichens, a waterfall. Ran my line again with Anita. The only capture was Akodon male 825 in trap 15. It had been in trap 8 this morning, which would be a movement of about 55 yards. Then we set 10? small Shermans along the edge of pasture and big dead quila above the road. Also two cage traps in the ditch along the road at km 1.950 along the road between Termas and Aguas Calientes. 1---2---3---4---\/--6--7--8--| |--9--10--11--12--\/--14-- 15--16-- | 5 || 13 | 44--43--42--41--40--39--38--37-| 36a,b,c | 36d,e,f | 35--34--33-/\-
