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.

Cloudy and cool. The shed skin of a rat snake has blown off the back roof and dangles in the branches of a walnut. In the next tree over, a gray squirrel walks to the end of a limb, sniffing each walnut, and picks the one at the very end.
