From whiskey river:

To the Light of September

When you are already here
you appear to be only
a name that tells of you
whether you are present or not

and for now it seems as though
you are still summer
still the high familiar
endless summer
yet with a glint
of bronze in the chill mornings
and the late yellow petals
of the mullein fluttering
on the stalks that lean
over their broken
shadows across the cracked ground

but they all know
that you have come
the seed heads of the sage
the whispering birds
with nowhere to hide you
to keep you for later

you
who fly with them

you who are neither
before nor after
you who arrive
with blue plums
that have fallen through the night

perfect in the dew

…and, from elsewhere:

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.
