The sky and ground nearly rhyme in their oppressive whiteness. A red squirrel sounds as if he’s having a psychotic break, trying to defend a hollow black locust no doubt stuffed with acorns and walnuts.

An hour past sunrise, there’s a growing radiance as blue sky spreads in the west. Even after all these years of wildlife-watching, I can’t stop marvelling at the acrobatics and shenanigans of gray squirrels.

Wind and clouds and the clattering of treetops rocking out of sync. Two squirrels hunting the last unfallen acorns keep climbing into the top branches of a big red oak, hanging by their hind legs to peel their prizes.
