Vespertina Cognitio 

Overhead, pelicans glide in threes—
         their shadows across the sand
                  dark thoughts crossing the mind.

Beyond the fringe of coast, shrimpers
         hoist their nets, weighing the harvest
                  against the day's losses. Light waning,

concentration is a lone gull
         circling what's thrown back. Debris
                  weights the trawl like stones.

All day, this dredging—beneath the tug
         of waves—rhythm of what goes out, 
                  comes back, comes back, comes back.
