An ethological analysis of the use of antlers as social organs by rutting bull moose (Alces alces gigas Miller)
Thesis (M.S.) University of Alaska Fairbanks, 1983 The behavior of rutting bull moose (Alces alces gigas) and their use of antlers as social organs was studied in Mt. McKinley National Park, Alaska during the autumns of 1977 and 1978. Bulls were placed into six antler-size classes. Expressive behavi...

Rates of bush thrashing, addressing threat and dominance displays, and frequency of bull associations with cows were all positively correlated with antler-size class.
