This week on Discover Nature, watch for an ecological engineer, and unsung steward of streams.
The American beaver is also North America’s largest rodent.
Their webbed hind fee, with large, flattened tails, dark brown fur, and pronounced front teeth, all suit these mammals well in their streamside habitats.
Beavers’ feeding habits vary with the seasons. During the summer, they eat corn, pond lilies, watercress, and other herbaceous plants.
