Re: World's Largest Beaver Dam
Always the engineer, I think that the dam building is a large part of child rearing; they need a stable water level to keep the entry to their lodge underwater (lest they and theirs be eaten) while keeping the dome of their lodge above water (lest they and theirs drown). That's why they hate the sound of running water and will throw all amounts of sticks at the loudest babble.
