The first thing to remember is that the "wild" in wildlife isn't an arbitrary distinction. These animals are not tame and are not in a zoo. They roam free in their natural habitat and sometimes they roam free in yours. It isn't uncommon for a moose to be strolling down a residential street looking for a tree to prune.
Wild animals in Alaska can be dangerous if they are provoked. They are also extremely protective of their young, so animals who have calves, cubs or some other kind of young, should be viewed at a good distance and with extreme caution.
