From time to time an elk bull’s nerves give up. He roars for a while, pushes trees over. He might be in a rut when it is necessary to demonstrate strength and might to competitors. Overthrowing and uprooting of bog pines cause sounds that are heard far away. The trees should be felled in a quiet period, in the morning or evening, so that the racket will carry across the fields. The larger the trees, the more powerful sound. Antlers clatter in addition to the racket so that the message about the tree-feller’s power can be heard yet mightier and further away. These are activity signs of an elk bull controlling his territory. Keep your ears open!
