30 to 80 mm long lying around the cage. The Oryzomys didn't touch theirs. Barebodo, Serrano warm. Visited by Michael Christie and grad student from Minnesota. Brewer, then by Hilda, then by Adrian and Lucy Moujean. Left at 6:30 to put traps at the first summit east of Cero Línea. Weather turns cooler and windy. Set out 9 cage traps, 17 Sherman, 17 Muenzer, and 10 steel traps. Total 53. Two of them around two old old blown-over but still thriving cypress with green grass under them but otherwise in rather bare stoney ground. Rest of line went from cypress clump to cypress through mostly blooming Palo Pichi (Fabiana imbricata). Some of it Pure Palo Pichi. Hasn't been grazed for years or decades but not much grass, only scattered low shrubbery. Anta put 30 MS, 5 steel, at 8 cage traps in similar habitat. We both saw the field course blunt rounded red droppings that we think are Euryoryzomys. Ran our traps at 10-12 by flashlight and NVG's. Saw 2 mice run from shrub at brush, probably also. Longi. Anta's traps had alive (baby) and 3 other longi, and dead 2 other longi, longi (adult), 1 Oryz, 2 calico, and 1 Eligia. Night half cloudy, moon ½.
