Pearson 1974 Tues. Mar. 19. [illegible] east of Matarain, 600 ft., Dept. avequiba, Peru after 2 days in Tacna getting the truck licensed etc, finally left about 10:30 A.M. Lots of Zootrichia capensis screeching about the city, such as Hotel Tacna and the Palace along Arequipa Bolognesi. Neither saw nor heard a single English Sparrow. The Zootrichias seem to have moved north that used to screege along Bolognesi. Drove north to Moquegua. The scrubby plain north of Tacna that was green last year in March is all dried up, but lots of mice there. Arrived Moquegua about 12:45. Post office closed, not open until 3 p.m., so we left for Mollendo. Fairly good, almost dried-up vegetation coming down into Matarain. Lots of mouse and/or lizard trails at one place where we stopped. The zone between Matarain and Mollendo, recommended by Holt-Hugbee, is dry, almost as "dust" as Novo Dava in 1973 March. Not enough rocks & shelter for mice, howerver, so we drove inland a couple of miles and camped at 5:30 p.m., clear windy. I put out about 38 small Sherman's baited with rolled oats. Center put out 15 large Shermans. Soil powdery dry, a chalk quarry nearby. A few small butter + ivy plants in bloom, a few clusters of Cordoloba costei looking sad. The weather in Tacna was overcast all three nights but cleared each morning, March 20 2 Phyllotis darwini in my traps, are often jerudts. None in center. No Zootrichias, heard burrowing owls and I think seed scrips. No ants.
