The antlers of an Alaskan bull moose can measure 12" at the base, span up to 6' and weigh 90 pounds. That’s some serious headgear! Bull moose try to avoid full-blown battles. Even when two prime bulls encounter one another, a bad attitude may be enough to make one animal back down. The pair will trot around flashing antlers, raking brush and groaning a challenge. They may rip vegetation from the ground with their mouths, jerking their heads up in a boastful swagger. If they are a match, the bulls will clash antlers in a furious fight. Eventually one bull tires, turns and runs. The victor may slam its rack into the loser’s body as he leaves. His strength and courage have made him king for a day!
