Still, citizen sparrow, this vulture which you call
Unnatural, let him lumber again to air
Over the rotten office, let him bear
The carrion ballast up, and at the tall

Tip of the sky lie cruising. Then you'll see
That no more beautiful bird is in heaven's height
No wider more placid wings, no watchfuller flight;
He shoulders nature there, the frightfully free,

-From Still, Citizen Sparrow by Richard Wilbur
