Part One

Cranes keep landing as night falls. Ribbons of them roll down, slack against the sky. They float in from all compass points, in kettles of a dozen, dropping with the dusk. Scores of Grus canadensis settle on the thawing river. They gather on the island flats, grazing, beating their wings, trumpeting: the advance wave of a mass evacuation. More birds land by the minute, the air red with calls.
 
A neck stretches long; legs drape behind. Wings curl forward, the length of a man. Spread like fingers, primaries tip the bird into the wind’s plane. The blood-red head bows and the wings sweep together, a cloaked priest giving benediction. Tail cups and belly buckles, surprised by the upsurge of ground. Legs kick out, their backward knees flapping like broken landing gear. Another bird plummets and stumbles forward, fighting for a spot in the packed staging ground along those few miles of water still clear and wide enough to pass as safe.
 
Twilight comes early, as it will for a few more weeks. The sky, ice blue through the encroaching willows and cottonwoods, flares up, a brief rose, before collapsing to indigo. Late February on the Platte, and the night’s chill haze hangs over this river, frosting the stubble from last fall that still fills the bordering fields. The nervous birds, tall as children, crowd together wing by wing on this stretch of river, one that they’ve learned to find by memory.
 
They converge on the river at winter’s end as they have for eons, carpeting the wetlands. In this light, something saurian still clings to them: the oldest flying things on earth, one stutter-step away from pterodactyls. As darkness falls for real, it’s a beginner’s world again, the same evening as that day sixty million years ago when this migration began.
 
Half a million birds—four-fifths of all the sandhill cranes on earth—home in on this river. They trace the Central Flyway, an hourglass laid over the continent. They push up from New Mexico, Texas, and Mexico, hundreds of miles each day, with thousands more ahead before they reach their remembered nests. For a few weeks, this stretch of river shelters the miles-long flock. Then, by the start of spring, they’ll rise and head away, feeling their way up to Sas-katchewan, Alaska, or beyond.
 
This year’s flight has always been. Something in the birds retraces a route laid down centuries before their parents showed it to them. And each crane recalls the route still to come.
 
Tonight’s cranes mill again on the braided water. For another hour, their massed calls carry on the emptying air. The birds flap and fidget, edgy with migration. Some tear up frosty twigs and toss them in the air. Their jitters spill over into combat. At last the sandhills settle down into wary, stilt-legged sleep, most standing in the water, a few farther up in the stubbled fields.
 
A squeal of brakes, the crunch of metal on asphalt, one broken scream and then another rouse the flock. The truck arcs through the air, corkscrewing into the field. A plume shoots through the birds. They lurch off the ground, wings beating. The panicked carpet lifts, circles, and falls again. Calls that seem to come from creatures twice their size carry miles before fading.
 
By morning, that sound never happened. Again there is only here, now, the river’s braid, a feast of waste grain that will carry these flocks north, beyond the Arctic Circle. As first light breaks, the fossils return to life, testing their legs, tasting the frozen air, leaping free, bills skyward and throats open. And then, as if the night took nothing, forgetting everything but this moment, the dawn sandhills start to dance. Dance as they have since before this river started.
 
 
Her brother needed her. The thought protected Karin through the alien night. She drove in a trance, keeping to the long dogleg, south down Nebraska 77 from Siouxland, then west on 30, tracking the Platte. The back roads were impossible, in her condition. Still shattered from the telephone’s stab at two a.m.: Karin Schluter? This is Good Samaritan Hospital in Kearney. Your brother has had an accident.
