Rain and fog shut out all sounds from the valley; a gobbling turkey and a pair of pileated woodpeckers are the loudest things. A titmouse sheltering in the lilac shakes the rain from his wings.

Rainy and cool. An eastern towhee is urging me—according to the time-honored birders’ mnemonic—to drink my tea, while woodpeckers large and small bang their heads against the trees.

For the third morning in a row, the thermometer hovers just above freezing as drizzle falls. Woodpeckers are already at work, beating their heads against trees.
