Evolution in Indiana
I thought that species took ten thousand years
to gradually evolve new strategies
to deal with shifts in climate or environment,
but after two snow-free years in a row
the local robins all at once decided
to winter here instead of flying south.
I watched them pace my lawn in late November,
debating like small Hamlets with their instincts:
"It's way past time to migrate; why haven't I?"
Since, every fall, a few old feeble ones
decide they'd rather risk starvation here
than drop off dead of fatigue in Alabama,
at first I thought it was their kind I glimpsed
rummaging discarded Christmas trees
for grubs and squabbling with the greedy squirrels
stealing birdseed from my neighbor's feeder.
But then, one drizzly January walk,
I spotted dozens, looking sleek and healthy,
plucking worms who'd washed up on my sidewalk.
Why here, where I was forced to grub for money
all winter long, when they could fly away,
I wondered as they hopped out of my path.
Does flying hurt so much they'd rather shiver
and see the sun once every other week
than perch in palms swayed by an ocean breeze?
If I had wings, I'd use them…and on and on
I muttered as I trudged around the block
in pointless circles, just for exercise,
hands thrust into my pockets, arms tight to sides,
like some huge flightless bird, while overhead
the most successful members of my species
winged effortlessly southward in high Boeings
invisible from our side of the clouds —
we well-fed and hard-working flock of Dodos.
