One of the most magnificent sounds you can hear on this planet is the bugling of sandhill cranes. Aldo Leopold called them: “The Trumpet in the Orchestra of Evolution.” Because the bugling carries so far, you can often hear them for some time before you know where they are. The sound carries on the wind from the far side of the marsh or out of the clouds. Even in a blue sky, the flock might be so high or far away that you can’t find it. Yet that spine-tingling music drifts down.
