Nesting Behavior of Ochrotomys nuttalli under Experimental Conditions

Abstract

Nesting behavior of the golden mouse, Ochrotomys nuttalli , was examined in experimental enclosures. Observed grouping patterns for both kin and random groups differed significantly from expected with nesting groups consisting of three or more individuals causing this difference. No significant differences were found between kin- and random-group frequencies, or between kin and random females, in groups of three or larger. Kin males, however, nested in groups of three or larger significantly more than random males. Females appeared to prefer a large social group, whereas males (especially nonrelated males) exhibited a more solitary behavior.
