Special Edition: Night Shift

When you settle into bed for the evening, another world awakens. Flying squirrels launch between trees, bats emerge from roosts and owls begin their silent hunts.

Your Lake County Forest Preserves provide the food, water, shelter and darkness these animals need during their night shifts. Despite their abundance and proximity, our nocturnal neighbors can seem mysterious. The dark obscures their unique activities.

Let’s peek behind the curtain.
