Probability of the Sparrow

The body wicks away its nest, leaves sediment. In salt the silhouette of a wolf or a sheepshead. Who knows who steals bones if  not the connoisseur of  bones, and who drops a crank behind the body if  not the one who drains the river bed? In unrest, buzzards. Or a flat line. The probability of  sparrows a spark between two enemy pistons. A dirigible built solely for the grave.
