They advise people to wear noise producing devices such as little bells on their clothing to alert the bears but not startle them unexpectedly. They also advise the carrying of pepper spray in case of an encounter with a bear.

Black bear droppings are smaller and contain berries and possibly squirrel fur.
Grizzly bear droppings have little bells in them and smell like pepper spray.
