Darwin's Dementia

Once upon a merry time
I was an aspiring birder-
Charmed by the shape & song & soar
Of crows robins & orioles
Not to mention the dazzle
Of darting hummingbirds
Or the swing of pigeons by the dozen
Across the Del Oro marquee
Even investing a hundred dollars
On a pair of nice Nikon binoculars-
Then one day
Purely by chance
I was surfing Wikipedia
And landed on a site
That presented an exquisitely
Iridescent blue-green citrus beetle-
Now I've set birds aside,
Now I've landed Darwin's Dementia-
I'm become an aspiring BUGGER
