I happened upon this scene, watching from my bedroom window yesterday.
The ground is layered with remains of several recent snowstorms–the most recent showering us with 6"-8" of amazing powder. One needs to know, then, how squirrels manage to navigate that–which is no different than their signature hippity-hop, hippity hop, of course. What is notable is that because of their short stature and long tails, their initial forays following a storm leave a marked trail–of long, punctuated slashes bellied through the snow, the tail dragging behind. It all leaves a quite decoratively marked snowscape.
