A mid-morning downpour. I push my chair back from the sudden curtain of roof-runoff and continue writing to the thrum of it. After half an hour it subsides into drizzle and birdsong. A male towhee flits through the yard, pursued by a pair of begging fledglings.

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.
