P. PEARSON 1955 Bright sun when I got to the Santa Eulalia traps at 8 a.m., probably no fog earlier, driving over Lima. These traps with 6 Ph. darwini. Drove up the Carretera Central to San Bartolomé and skinned. Then put out about 60 Swedish mouse traps on a north facing slope 1 mi. E of San Bartolomé. Habitat mostly weedy. Thorny "molle" imazonia trees down on the valley floor, plus weeds. Even the steep slopes quite weedy, with only occasional cactus. Some grass. Some of the dry weeds had high and many of them with stick-tight seeds. Some rock outcrops, but the weeds much more dense for what I consider good darwini habitat. Saw only one set of droppings: Dove, poor-will, hummer, flycatcher, anis. Aug 7 August 7 Fog at Chozen overnight, up at least to a mile above the Santa Eulalia turnoff but not much higher. Traps held one badly eaten zuniga rat (Ondiziomys). Most others either empty or bait gone (ants). Will have to come back with bigger traps. About 3 p.m. set = 55 Swedish mouse traps between Suero and Matancera, about one mile west of Matancera, I think, but I didn't go all the way into the town. The hills here are grassy-weedy with some cactus, quite a few century plants, thorn trees and thornless ones, some mesquite. The weeds not as thick as at San Bartolomé, but thinner than I think of for darwini.
