Because they are so much like us. The way they work until they drop, like us. They commune together in small homes pieced together, like us. They work both day night for long shifts, like us. They get pushed around by large corporations and developers, like us.
Beavers are social animals.
The so-called beaver lodge is a unique structure. Three distinct kinds exist, their differences depending on whether they are built on islands, on the banks of ponds, or on the shores of lakes. The island lodge consists of a central chamber, with its floor a little above the level of the water, and with two entrances. The lodge itself is an oven-shaped house of sticks, grass, and moss, woven together and plastered with mud, increasing gradually in size with year after year of repair and elaboration. The floor is carpeted with bark, grass, and wood chips, sometimes with special storerooms adjoining.
