8/5/25 August 5, 1925 - Rather warm during the forenoon but in the afternoon it was windy. Late during the day it was thundering in the distance. In the corn patch I caught a spiny-pocket mouse, its stomach content consisted of corn grain pulp and round-worm parasites (Nematodes)? I discovered a colony of bats in a canyon. They are a little brown bat which I have not determined as yet. The canyon was quite shady at this place. The bats were clinging to the shaded underside of some huge boulders. They were easily frightened from their place of concealment for they began to fly and chirp when I was about twenty paces away. There were about 50 bats in the colony. Of the 9 specimens that I collected 8 were females. They were obviously all the same species. August 6, 1925 - Warm during morning. Windy at noon and during the early part of the afternoon; raining late afternoon and evening. Collected another female monkey (Ateles). She was alone and was carrying a 40 m.m. embryo. I believe that the female monkeys must leave the band as soon as they are bred. I collected some more bats today, nothing in the traps.
