4 April 24- Lago Espejo Chico. Night clear and cold; ice on the car. Traps MUCH less productive than yesterday. My 25 Shermans caught 2 Oligos and 1 Chelemys, and my 25 MS caught 2 Oligo, 2 longi, and 1oliv. Sage's 25 Shermans caught 1 Oligo, 3 longi, and 1 live Chucao; his Museum Specials 6 Oligo and 1 Geoxus. Total for 100 traps on a clear frosty night: Trap success forall species 19%; for Oligos 11%; for longi 5%. Found one rosa mosqueta bush in the bamboo and tangle at the bottomof the hill near the soccer field (and our camp). This is the only rosa I have seen here. Saw a hummingbird near camp, but nothing blooming. Saw hare droppings but no hares. Heard no owls, saw no raptors, no carnivores except 4 dogs hunting through the forest. Sage went off with Willig for an hour in search of Rauli seeds. Willig had never seen a pudu near here, but there are wild pigs (but we saw no sign). Red deer have not reached here. We have not yet seen a single hare squashed on the road; compare with precvious years. After processing some but not all of the mice, left for Bariloche. Brought three live Oligos to test whether they like seeds of Scotch Broom, but squashed one of them while transferring to cages. I gave each 25 broom seeds and a pinch of rolled oats, plus a small piece of apple. April 25- Bariloche. Mostly sunny but cool. Processed mice. None breeding. The one Geoxus dissected had "liquified" (=decomposed) more than any of the Abrothrix or Oligoryzomys kept on ice for the same length of time. Another similarity to Blarina? In the morning, one of the Oligos had eaten ALL the seeds and left only one flake of oats. The other left nine seeds. So they DO eat Scotch Broom (or is it European broom?) Went to Patricia Fierro's for tea; Jorge was off at an asado. The weather here has been mild, in spite of El Nino. Her garden is beautiful even so late in the season. Saw a hummingbird there feeding on Red Hot Poker. April 26- Bariloche. Overcast. Went to Chalhuaco with Sage, Michael and Patricia Christie and two of her kids. A wee drizzle at times. There were nine cars at the Refugio! and the road was much improved. The autumn colors are just beginning. I dont remember ever seeing so many amancay plants, it must have been a spectacular January. Only two plants with flowers still. Collected one plant with four seed pods, which exploded nicely in the middle of the night. The single bamboo plant above the refuge looked robust, with several yearling culms. The
