There is an old joke. Camper asks leader: “Do bear whistles work and how do you tell if you’re following a brown bear or grizzly bear?” “I’ll answer the second question first. Brown bears are vegetarians; their spoor will have seeds and bits of vegetation. Grizzly bears are omnivorous; their spoor will contain bits of bone and whistles.”
