A cold wind and enough clouds to keep frost at bay, though I doubt the tender young leaves and blossoms will be so lucky tonight. A winter wren burbles by the springhouse. High on the trunk of the big tulip tree, the white breast of a brown creeper inches skyward.

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.
