墨守成规是可以的(When being in a rut is OK)

经过数月的吃食、漫游和躲避捕食者，阿拉斯加麋鹿在秋季试图繁殖这一物种，这一季节被称为发情期，发情期从8月底到10月初。雄性会在树上标记自己的气味以吸引雌性，并与其他公牛争夺雌性麋鹿（称为母牛）。

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 August to early October. Males will mark their scent on trees to attract females and fight other bulls for access to female moose, called cows.
