Estuary
Downriver, below the final bridge,
The last of the swans patrol –
To meet the early terns, who reach
Only this far from their native shoal.
Passing strangers, side-by-side,
Sharing the brackish tide.
Up-ocean, above the muddy flats,
The first of the mussels are found
To meet the sticklebacks and sprats,
On the down-stream, up-bore bound.
Passing currents, slow and wide,
Sharing the brackish tide.
