Episode 45: Squirrels, Their Nuts, and the Subnivean Zone


Unlike many other animals, squirrels remain active and present throughout the winter. They keep themselves fed by maintaining various caches of nuts and seeds. Casey describes how squirrels store and retrieve their scattered stashes.

Sometimes squirrels are found in the subnivean zone – a relatively warm area between the ground and the snow pack. Daniel takes us down to this little explored space where life abounds throughout the winter. One way foxes and owls keep themselves fed during the winter is by hunting tiny creatures that live below the snow.
