A: For Canadian creatures to survive the winter they can either leave, or they can hibernate or they can tolerate. They'll often sleep together — especially on the colder nights — and they'll huddle in a pre-selected winter roost, like an empty bird box. And if it really gets cold, they'll dive into the snow to wait out heavy storms. The hot internal blood warms up the colder blood coming in from the cold legs. Larger animals like moose they've got the long legs, so they're adapted to move easily through that deeper snow.
