Clear at sunrise, the western ridge brick-red above a meadow full of fog. Sound is out of the east, so field sparrows are answered by quarry truck beepers, and a pileated woodpecker by the grinding of rocks.

Foggy and warm. Two nuthatches at the woods’ edge tangle in mid-air, tumbling a dozen feet before retreating to separate tree trunks. Near the top of the big tulip tree, a gray squirrel is leaping from limb to limb.
