The Cardinal and the Horsefly

Revised version:
In the crisp spring air, the cardinal chased the horsefly, male, young, furiously fast, a bright red streak cutting through the blue of the sky, his female partner, brown, still, watching and waiting in a nearby tree, the horsefly, charcoal black, loudly buzzing, wildly swooping and turning, narrowly escaping the deadly red dart at every turn.
