Flashes.
Lunchtime for swallows, winging in
to meet and cheat flight of newly hatched
tiny insect-delight
shows unbeatable aerial display, highest
of feathered skills turning at will, defying
speedometer readings
and rapid as any fastest express train,
each avoiding the crowd of beaks,
they dive open-mouthed.
Pinions narrow for rapacious speed
almost as fleet as nearly-seen flashes
of flies disappearing,
arrowed shapes of famished jaws move
to start greedily swallowing living food
and assemble for more
like jet-propelled aerial sharks starved
for nutrition they dart then soar
leaving mere humans agape.
