A sunlit pool, a space to dart
From off a branch the black and white
As clean as rapid’s foam and night:
A dancer pirouetting up
And back to bathe and preen and spy
Then off again to spin and snap
With flicking wings and sniper’s sight
A moment whirling in sunlight.
The spiral movements of its life,
From Senegal to ancient oaks,
Its call repeats, its circle turns,
Its world in orbit round the branch
Where sun meets black and woodland white:
A helix twist of vaulted flight.
