Bellati at INTA. Then stopped at the Delegacion Tecnica of Parques. Gustavo was there and Anahi. She is happy with the computer that I brought her. A man at INTA who lives in Melipal says that he is plagued by mice right now. He says they are not colilargos (Oligo), but have shorter tails. From his description they could be house mice or Abrothrix. Gustavo at the far end of Melipal says that his cat is bringing in many more mice than usual. Abouot 2 oclock left foour Villa Angostura. Stopped at the Park Guard place and talked with Eduardo Lujano but got little informationn on the mouse outbreak. They seem to think it is over. Remorino no longer works at the Park Guard station but still lives in Villa Angostura. Then stopped at the Lago Espejo Guard Station and talked with Willig. He thinks the ratada is over; no more corpses on the beach. I asked him about Weismannia trees. He says there are numerous around th edges of both lakes near the water, some a foot or so in diameter, none accessible by foot from his house. The old guy at Espejo Chico (Matus) is seldom there any more because he is going blind. Talked briefly with a young guy Lorenzo, not the same young man as last December. Then we camped at the same site as before. Dick put out 25 MS, 25 Shermans, and 11 jump traps baited with pate, the 50 mouse traps in some of Anita's old lines. I put out 25 MS and 25 Shermans in my same old line that ran up along the fence just across the bridge, up to the log-encircled meadow. Started to rain and even a little hail just as we finished. This will probably spring some of the snap traps. Light rain off and on during the night. April 23- Lago Espejo Chico. On my line there were only 4 Museum specials that were not sprung. Altogether my MS held 7 Oligo and 5 Abro longi. My Shermans held 2 Oligos, 5 longi, 2 Abro olivaceus, and 1 Geoxus. Sag'e 25 Museum Specials held 12 Oligos, 2 longi, and 1 oliv. 6 traps were sprung empty. His 25 Shermans caught 4 Oligo, 2 longi, and 2 olivaceus. The 11 steel traps caught 1 Abro longi, but dont count in the calculation of trap success. Totals for 100 traps on a rainy night: Trap success all speceis 46%; Oligo 25%; longi 14%. Dissected all day. Mostly cloudy, then set new lines of 50 MS and 50 Shermans. Sage's line was across the creek along Anita's old line toward the houses. My line began across the road on this side of the bridge through nire and bamboo, then this side of the road near Berberis patches and bamboo, then along the bottom of the hill to camp. This was all terrain trapped in November December.
