Thickening contrails stripe the sky. Two ravens fly side-by-side over the house, trading hoarse commentary. The blur of hoarfrost.
The return of the cold has saved the last, handkerchief-sized patches of snow. In the east, a silent jet trails the smallest of wakes.
Feathery contrails outline a wedge of blue. On a high branch, three mourning doves sit facing the sunrise. The middle one preens its wings.
By midmorning, all the white crosses left by jets have disappeared into another cloudless sky. A soft bang as a junco side-swipes a window.
Almost Cartesian, this grid of clouds: contrails at varying stages of decay. From up in the woods, wingbeats of some large bird.
To the northeast, seven parallel contrails spread and merge. An eighth appears through the treetops across the yard, and I have to sneeze.
Blue sky carved up by the ley lines of industrial man. Who else leaves such arrow-strait trails for mile after mile? Only Coyote.
