an endless silent singing

Invisible even in a telescope magnifying sixty times, even in the purest summer sky, they drifted idly above the glittering Channel water. They had no song. Their calls were harsh and ugly. But their soaring was like an endless silent singing. What else had they to do? They were sea falcons now; there was nothing to keep them to the land. Foul poison burned within them like a burrowing fuse. Their life was lonely death, and would not be renewed. All they could do was take their glory to the sky. They were the last of their race.
