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.

Three or four slow-moving squirrels crowd onto the big tulip tree. But there’s a loner 50 feet away, diving repeatedly into the snow as if unable to locate a buried nut. After a while, he retreats into the canopy to eat black birch seeds.
