When being in a rut is OK

After months of eating, roaming, and avoiding predators, Alaska moose spend autumn trying to propagate the species during what is called the rutting season, which runs from late September to early October. Males, called bulls, will mark their scent on trees to attract females. They’ll also fight other bulls for access to females, called cows.
