Pond use habits of moose (Alces alces americana ) were studied during summers of 1981 and 1982 in the Mooseleuk Lake area of northern Maine. Five female moose were radio-collared and located 454 times during the study. collared cows exhibited a preference for aquatic areas during the summer. Of 804 moose observed in 1121 hours of pond observation, 43.8% were bulls, 36.6% were cows not accompanied by calves, 15.4% were cows with calves, 1.6% were lone calves, and 2.6% could not be classified. A peak in pond use was observed for bulls and lone cows during the last 2 weeks of July in both years. peak pond use by cow and calf groups occurred from late August to early September. Moose, in general, exhibited a diurnal peak in pond use during the early morning (sunrise-0900) and late evening (1700-sunset). Mid-day periods (0900-1700) were used to a lesser extent. Bulls preferred the early morning period whereas cow-calf groups used all daylight periods proportionately.
