Overcast and still. A gray squirrel stashes a husked walnut five feet off the ground in the crotch of a lilac stem—the first I’ve actually seen one do this, though I’ve noticed walnuts stashed in shrubs and assumed it was the work of squirrels. Or perhaps just this particular squirrel, unconvinced of the need for burial.

Breezy and cool, with occasional outbreaks of sunshine. It takes me two hours to work out that the soft clucking sound I’d thought was a hen turkey is actually a branch rubbing against the gutter for the back roof. A chipmunk rummages under my chair, then scuttles back under the small woodpile next to me.

Clear and cold, with an inversion layer bringing quarry and highway sounds out of the east. A female Carolina wren ticks quietly from the thick shrubbery around the springhouse. Cold as I am, I luxuriate in the absense of mosquitoes.

Drizzle thinning into wind-blown mist by mid-morning. The sky brightens. A pileated woodpecker clings to a skinny locust tree as it sways in the breeze, taps a few times and then tilts her head to the side as if listening for a response.

Overcast and cool. A pileated woodpecker flies into the dead top of the tallest black locust in the yard, seemingly oblivious to a swirling conflict between a small flock of local jays and two migrant sharp-shinned hawks. A slow inspection of the treetop turns up nothing worth tapping for, and she flies off, leaving the tree to the jays.

An hour after the last raindrops, wet leaves glisten as the sun glimmers through thin clouds. The sound of teeth chiseling through a walnut shell. The stems of bent stiltgrass in the meadow begin to redden.

Sunny and cool at midmorning, with the smell of woodsmoke drifing up from the valley. The bluejay who stumps the bird app is making his one-of-a-kind call — almost a croon. At random moments, black walnuts drop onto the driveway with a thud.
