My first sonnet

My first sonnet, circa 1991 (when I was 16). I know line 2 is short, but there IS a volta!

A MINOR ACCIDENT

I saw upon the road to school today
Blood, bones and feathers on the tar.
Some little bird had flown down on the way...
And been squashed flat by some enormous car.
Charles Darwin tells us in his famous Theory
How birds and beasts adapt to suit their need,
A Camel in the desert is not weary,
Giraffes from trees as tall as houses feed.
So blackbirds, fearing danger from the sky,
From falcons, hawks and other birds of prey
Fly low in terror. That's the reason why
The car had hit the one I saw today.
So, soon will frightened country ones fly down,
And those that rise, be birds-about-the-town?
