Pearson 1984 34 Oct,29 Bariloche. Arrived from Buenos Aires about 11 a.m. Completely overcast, 3°C, rain and snow. In B.A. Saw Willie and Mary for Menquin, Osvaldo Reig, and student Claudio Zilingardi and Miguel Pallarolo, Reig teaching at the University, not director of the Museum (Director is still Gallardo), Crespo still the museum- ologist. Willie is teaching + Mary for her a CONICET Fellowship. Also had lunch with Krantz, Juan, Maria Burch (mouse competition) and another student doing learning predictions. Also tea with Nottbohm parents, a thunder rain storm overnight in BA had blown down by trees along the Costanera. Javier Calvo came to call, was completely snowed out of Cerro Otto during the winter. He took a helicopter ride over the stuffs; it was all white, with dead sheep etc. Everyone agrees worst winter in 40 years. Oct.30 Cold, scattered sun. A few daffodils out; apple trees in town are blooming. Michael Christo in BA. Saw Marcello Bettinelli. Bombardier pheasants just beginning to leaf. A few Scots broom blooming. I rose out to Cerro Grande and looked for Reithos leucurus (more) and collected out pellets (about 1 qt.). Found mouse traps (INTA?) up near the cliff. Maybe Adrian Pederson has been trapping there (and collected pellets?). Solo of Barcelone; Polo Vichir just below the cliff,
