The mating season for moose (Alces alces) is just starting, and it peaks around the end of September or the first week in October. By this time bulls have shed the velvet that provided a blood supply to their antlers while they were growing during the summer. Occasionally you see the remains of the velvet hanging from their antlers at this time of year (see photograph). During mating season, bulls are rushing through the forest, seeking a receptive cow and engaging in mock battles with other bulls for the female’s attention. A bull uses his antlers in these challenges, engaging in “antler-pushing” with other males. He also uses his antlers as a tool for thrashing brush and for rooting plants from the bottom of ponds.
