CURWOOD: When night falls and animals can no longer see many instead rely on sound to find each other and communicate……. As Living on Earth’s Explorer in Residence Mark Seth Lender found in the mountains of Colorado.
LENDER: Two bald eagles come through the woods, a last shadow in the failing light. All afternoon, not far from here, eight of them perched in the same tree. They were waiting for the slough to thaw, to feed, upon the carp beneath the ice. The thaw never came. Now the eagles are headed home.
There is no moon… Moments later it is too dark to see.
CRANE SOUNDS
A flight of sandhill cranes crosses over, towards the shallow marsh where they will sleep, hidden between cattails coated and crystalline with frost. Their flight song and the woosh of their wings trails behind them, dimming as they speed.
OWL SOUNDS
The great horned owl sounds, a patina of deep strong notes which carry through the canopy to where his mate guards their nest. At a deserted farmhouse not far from here I’d seen another owl return at twilight. A dark shape.
OWL SOUNDS
The silent semaphore of his wings. He hooted. Then again.His mate would not answer. Because I was there. He flew away.
But now among aspens and oaks in this quiet and secluded place and with the safety of a moonless sky, this time the female replies, and the owls talk, back and forth, her voice thin, his low and smooth as butterscotch and rum.
OWL SOUNDS
Horses come through the gate. Branches snap as they mill among the trees. The great horned owls change place, the female gone off to hunt.
It begins to snow…
Beside these woods is a thicket, then furrowed fields sown with corn and wheat. Wild geese are bedded down there, and across the section fence, cattle.
A yelp. Then again from a different part. Short. Clipped - Coyotes, hunting. The farm dogs hear it too and bark. Indignant. Pretending. Though not chained they stay put.
BULL SOUNDS
Yip!
Yelp!
A high thin whistle like the bugling of an elk....
BULL SOUNDS
Now, all the coyotes know where everyone is and perhaps from that alone what they are about to do.
The geese call out.
GEESE SOUNDS
The bulls along the boundary line bellow loud and long and deep, Greek chorus in this vital play.
BULL SOUNDS
In the Dark, Sound is Sight.
CURWOOD: That’s Living on Earth’s Explorer in Residence, Mark Seth Lender.
