for 2½ hours. Got up at 3:45, found and followed 2 others, put one of them to bed long after dawn. Dec.1 Morning mostly clear, scarce. Rafters at 7:00, after stopping last night’s Rattles activity. Canta’s box had 2 adult & 8 Eligmodonta, 1 ad & Plagiolepis, 1 egg & Euniceumpe, 1 egg Rattles, 3 also Long’s, and 5 eggs to old Euniceumpe. 13 mice of 6 species — including Euniceumpe, x my traps had 1 adult Rattles (right up in the bare-ground cipres), 8 cavies, 1 also Long’s, and 2 Crypsumpe x 12 mice of 4 species x Heard barn owl several times during the night. The condors were off high long before sunrise. The wutwara no longer in the trees at San Ramon. Note that the composition of the cipres balls is not unlikely that of Cueva Traful. The retreating glacier may have left a lot of bare rocky gravelly soil being recorded by cipres x Note also absence of also Rattles in our catch, Back to Bariloche by 10:30 a.m. Dec.2 Put cipres twigs and branches into cages with Euniceumpe and with Crypsumpe (plus apples and dog food and green grass). The Euniceumpe struffed bark from small twigs 2 mm in diam. but not from larger ones up to 10 mm, which is the size I remember being gnawed at our camp across the river from Cueva Traful. Numerous green branches
