A cold front that began blowing in just before dawn has brought crystal clarity not just to the air but seemingly also to each bird call. Two wood thrushes tangle at the woods’ edge and retreat, each singing short phrases as if uncertain how their whole song goes.

Almost all the local marmots appear within the space of a minute: a groundhog pokes its head up beside the porch, a chipmunk is chased out of the black walnut tree beside the road by a gray squirrel, and a red squirrel scolds from the springhouse.

Neither too cool nor too warm, with clouds yet to find the sun. The irises are at their peak of blooming in my front garden, and at the woods’ edge where several yellow ones survive as relics from an era of moved lawns and decorative fences fifty years ago.
