The hedgehog in its burrow, the badger in its sett, the rabbit in its warren, the beaver in its dam—to each their own habitat!

To each their own habitat! Under the ground or on it, amidst root systems, in tree trunks, or on treetops, deep underwater or atop mountain peaks: at every elevation in the natural world, animals eat, sleep, reproduce, and care for their young. But watch out! Predators are always on the prowl!
Where do animals hide, then? To each its own refuge and method! Each knows exactly where and when to build its shelter, and what to build it with!
