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.

Sunrise brings birdsong: a Tennesee warbler’s blur of high notes answered by a towhee’s interrogatory tweet, and a white-throated sparrow’s “Oh, sweet Canada” giving way to the reedy whistles of cedar waxwings, tut-tutting robins, and a winter wren’s liquid braid.
