P. PEARSON 1950 less than 5 days old is resting 7 feet up in a bird about 3 yards from camp. There seem to be fewer birds here than last camp. Saw my first nocturne in a gloomy glade. after dark I retreated from the luting grates to bed. Had just gotten to bed when Savage reported a set up a tree about 10 feet from the table where the rodents playing. I shot it - Marmosa 3053. June 26 7 1/2 km E Villanueva, 1400ft, Huila Colombia Shinned marmosa before breakfast, then off with Savage and Pero to the floodlands. Watched them bundle up a ground sloth skull + femur, then carried the skull back after lunch. Looked for small mammal bones but found only fish, crocodile, and reptile. Certainly lots of bones around. Don't know what kind of small mammals live out in the floodlands, but it sure looks like a good place for Dipodomys - saw some small mammal footprints in dusty places. Dozens of 3 birds (snubler) especially near water + vermillion flycatchers were the most conspicuous birds. Few legua. People at the ranchhouse between here and the floodlands say that a few bats live in little caves in the dry wood near their camp, but that many more are in a big cave somewhere below them. Put out 14 mouse special baited with oatmeal in thick thorn forest. June 27 rock-lighted probant an hour, mostly along the road. Saw 2 allante, 2 poor srella, and 1 serck? owl. Nothing in the tops in the morning so went birdleg
