Abstract: Ontario. Canadian Field-Naturalist 100(4): 537-544. An Ontario population of Zapus hudsonius was live-trapped from 1978 to 1982. The active season was approximately 18 weeks long, with males emerging from hibernation two weeks before females in early May and entering into hibernation two to four weeks before females in late August or early September. Old individuals entered before young. Although reproductive activity occurred throughout the active season, females were never observed to be lactating or pregnant more than once in a given year. Overwinter weight loss was similar in males (36.8%) and females (34.5%), but overwinter survival appeared higher in males (39%) than in females (18%). Of the 208 individuals caught, six lived at least three years. Our data show a population of Z. hudsonius in southern Ontario with a shorter active season but greater longevity than has been reported for more southern populations.
