Aquatic Feeding By Moose: Seasonal Variation In Relation To Plant Chemical Composition And Use Of Mineral Licks, D. Fraser, B. K. Thompson, D. Arthur

Feeding Behavior Collection

Activity of moose (Alces alces) was studied at aquatic feeding areas and at natural, sodium-rich licks during four periods covering late May to early September. Aquatic feeding increased from period 1 (late May and early June) to period 2 (late June and early July) and had declined by late July. Major activity at mineral licks occurred earlier in the season than aquatic feeding, especially for males. Chemical composition of aquatic plants showed no seasonal changes corresponding to the peak of aquatic feeding in period 2, although the sodium content of some species declined in period 3. We suggest that moose …
