Why does a spiral preen?

I'm thinking of birds; how they preen.  How wind, just lusts to be a spiral, and spiral all winged-ones upwards.  And onward. Their itinerary, never casual nor complacent.

I'm thinking of how changing light fashions a haiku.

How a spoon spiraling, fashioned last night's chicken-lemon-curry soup.  How that spoon then was the proper tool to serve.

For sure, a spiral preens the inward and the outward.
