#5 also young #6 + #7 Peromyscus calif truei gilberti Feb. 27. 1939 This specimen has been in captivity since Feb. 18. It was sometime before I decided it was a californiai rather than a truei as it was exceptionally small or young. But its actions were quite distinct from those of truei gilberti. It never took refuge under the cotton placed in cage, but would huddle in a corner with back towards observer. Particularly the tail was held between the legs up under the body, or else bent around body so that it was up near the shoulder region. By the end of a couple of days, it laid on top of the cotton a few times, but then on its side with tail curled around. Thus 9). Since then it has remained huddled in a corner more often then in or partially under the cotton. It consumes a great deal of food as well as water & grains frequently on screen, leaving none so particularly in 1 place polishing up the "lead?" wire in this spot. Earlier this A.M. it was tearing the cotton apart with its mouth, it making a squeaking noise similar to that of maniculatus gambeli but not as loud. This is the 1st Peromyscus that has done this well in separate confinement. The 2 maniculatus never made noise when separate but only after 5 & 9 who put together. Feb. 27. 1:30 P.M. Observed cage & noticed young. Apparently the squeaking I had heard in the morning about 10:00 to 11:00 was that of young.
