O. Memmler 1943 Perognathus californicus June 14, M.U.Z. turning the seed in his hands, like one would turn corn on the cob, using his incisor teeth to crack and peel off the shell. 11:30 Pat sitting in doorway of rebuilt nest eats a carrot (piece). She held Carrot like this: [illegible] She ate about 1/2 the piece which is about x 1 as drawn. She dropped remainder in doorway and went inside 11:45 I put pat in a glass jar and had some seeds in the jar for her to eat. I held the jar over my head and watched her pick up seeds with both hands and rotate them for a few seconds and then put these either into the pouches or mouth with both hands. I think they were being put in the pouches because that she did not stop long enough between seeds to be eating them. Mike when put in the same jar did not eat, but rubbed his face and the base of his vibrissae vigorously for a while. Then using one hand on either side of his face, he stroked vigorously along his jaw until his cheek pouches turned inside out. He seemed to be able to draw them back in without using his hands. The pouches were returned quite suddenly, as if by muscular contraction.
