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.

A dawn bright with snowlight, the storm a kind of theater in which the play consists of a thin white curtain falling and falling. As the temperature inches up, the flakes begin to fatten. A squirrel dashes to the end of a limb on its snow-free underside to pluck one of the last unfallen black walnuts.

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.

Sunrise delayed for a few minutes by a low bank of clouds. A gray squirrel emerges from its nest high in a black cherry and dashes down the newly exposed trunk. A robin adds a few tut-tuts to the chorus of white-throated sparrows.

Bright periods alternate with gloom on a cool, cloudy morning, with an intermittent breeze paging through the tulip tree leaves. A sound like the clacking of a typewriter as a squirrel trots across the metal roof overhead.
