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 …

Predation By Wild Coyotes: Behavioral And Ecological Analyses, Michael C. Wells, Marc Bekoff
Ethology Collection
Predatory behavior of coyotes (Canis latrans) was studied between 1977 and 1980 in the Grand Teton National Park, Jackson, Wyoming. Major prey were voles (Microtus spp.), Uinta ground squirrels (Spermophilus armatus), pocket gophers (Thomomys talpoides), and grasshoppers (Locustidae). Coyotes typically rushed and ran down squirrels; when hunting mice, coyotes pounced and stabbed at them with their forepaws. Sequence structure was similar, though sequences directed to squirrels were significantly more variable. When juvenile coyotes hunted mice, sequences were similar to those performed by adults that hunted mice. Adults and juveniles were about equally successful. The size of prey last eaten influenced …

Behavioral Ecology Of Coyotes: Social Organization, Rearing Patterns, Space Use, And Resource Defense, Marc Bekoff, Michael C. Wells
Ethology Collection
Two groups of coyotes in which genealogical relationships were known were studied in the Grand Teton National Park, outside of Jackson, Wyoming, U.S.A., from 1977-1982. One group, a pack consisting of parents and some non-dispersing and non-breeding offspring, defended a territory and the food (mainly elk carrion) contained within it, especially during winter, and also had helpers at den sites (5 of 6 were males). The other group, a mated resident pair, all of whose young dispersed during the first year of life, did not defend a territory and never had helpers at dens. Delayed dispersal and retention of some …
