Beavers are vegetarians, and lily tubers are a favorite foodstuff. Because beavers are crepuscular (loving the twilight), you’ll see them most often at dawn and dusk, which accounts for the predictable in-time of this beaver family.
Beavers were nearly extinct because of the fur trade. Every time I have the privilege to spend time with an animal that barely evaded extinction (Peregrines, Brown Pelicans, egrets, sea otters, etc.) I’m reminded of this John Muir quote:
“God has cared for these trees, saved them from drought, disease, avalanches, and a thousand tempests and floods. But he cannot save them from fools.”
May all beavers and their brethren be so fortunate as to enjoy their lives, eating lilies on the lake, without running into those fools.
