Once upon a time, before humans diverged from chimpanzees or the had been carved out of its rock, an extraordinary bird walked and flew the earth in the area we now call Nebraska. The bird stood some four feet tall and had a wingspan of more than six feet. Its Miocene neighbors included the saber-toothed deer鈥攚hich sounds like a Monty Python joke but really existed鈥攁nd prehistoric versions of the rhinoceros and the camel. The camels and the weird deer are gone, but astonishingly, the bird鈥攐r its structurally identical relative鈥攊s still around. We know it as the , and while this most ancient of birds would be a marvel in any form, it happens to participate in one of the great mass migrations on the planet, making a journey through space that is as remarkable as its journey through time.
Between February and April, more than half a million sandhill cranes crowd through a short stretch of the Platte River of central Nebraska, staging for an odyssey that ends as far north as the tundra of eastern Siberia. Along the Platte, having already flown some 600 miles from the American Southwest, they will gorge themselves on the abundant remains of numerous cornfields, gaining 20 percent of their body weight in anticipation of the thousands of miles still before them. But despite their frenzied feeding, these social birds鈥攚ho mate for life and remain behind if their mate is sick or injured鈥攕till find time to do the thing for which cranes are most famous: dance.
Departing New York City for Omaha in peak crane season, I can鈥檛 help marveling at my own lucky journey through space and time. Ever since a stranger鈥檚 chance comment about the birds of Central Park led me to an introductory birdwatching class at 15 years ago, I have been in love with birds and perpetually grateful to them for opening up to me the hidden wild places in my city, my country, my planet, and, most surprisingly of all, myself.
From Omaha I drive 182 miles west to Kearney, Nebraska. The moon is nearly full, massive and orange. Part of me simply decides that this is what happens when you fly to the middle of America to look at cranes; things get bigger and more beautiful, or at least noticed with a new eye. But the next day the moon is on the cover of the , and I learn that it is a 鈥渟upermoon,鈥 closer to the earth than at any time in the past 20 or so years. Back home I might have seen a fat moon rising over the Empire State Building, but to have the oldest birds on the planet intersect with it, and with me, I need to travel 1,300 miles, to a particular place at a particular time.
The island I live on is sometimes called 鈥渢he crossroads of the world,鈥 but that depends on your definition of 鈥渨orld鈥濃攁nd 鈥渃rossroads.鈥 Look back into the 19th century, add in the overlapping trails of Pawnee and Sioux, millions of bison, the Oregon Trail, the Union Pacific Railroad, and the Central Flyway for migratory birds, and suddenly the middle of Nebraska, which is smack in the middle of the United States, has a claim to make as the literal and spiritual intersection of a vast array of competing forces.
I鈥檓 in a hurry to meet the birds, so I welcome the 75 mile-per-hour speed limit on Interstate 80, which follows the contours of the Platte River鈥攋ust as the Mormon Trail, the Oregon Trail, and the Pony Express once did. In those days Nebraska was considered part of the 鈥渢he Great American Desert,鈥 little more than a wild corridor to greener pastures in the west. When Francis Parkman passed through the Nebraska territory in 1846, making notes for The Oregon Trail, he observed, along the banks of the Platte, the 鈥渟hattered wrecks of ancient claw-footed tables鈥 that desperate emigrants had, in exhaustion, 鈥渇lung out to scorch upon the hot prairie.鈥
The unrelieved sameness of I-80 does little to recall those days. Only the big moon evokes the world as it was鈥攁nd of course the cranes, which I begin to see amid the stubble of cut cornfields along the side of the road, 200 or so yards back from the highway. They leap into the air, squabble, take off, land, toss the occasional stick into the air with their bills, bow from time to time, and most of all feed with their heads down, their long necks extended.
Corn-made fuel has a complicated history for humans, but raw corn, which can make up more than 90 percent of the sandhill crane鈥檚 diet, will power the birds for several thousand miles, and I shudder to think what would happen if more efficient combines are created that eliminate the gleanings the birds feast on, though their omnivorous opportunism鈥攖hey鈥檒l eat seeds, berries, insects, earthworms, mice, snakes, lizards, and frogs鈥攈as preserved them in the past. But the concentrated food of farms helps compensate for the lost foraging areas and fast-running rivers once abundantly at their disposal.
For now there is plenty of corn and there are plenty of cranes. I almost don鈥檛 want to see them yet鈥攚e have a date for early evening, when I鈥檒l be in a blind at , waiting for the sun to go down and the cranes to come out. But I fight this artificial impulse to falsify what I鈥檓 actually seeing. These are not backstage actors whose show won鈥檛 start till curtain time and I鈥檓 in my box; they鈥檙e big, gray, semi-graceful birds that live alongside the industrialized world and whose leaps and jabs are鈥攁dmit it!鈥攖he dancing I鈥檝e been dreaming about. They鈥檙e not the ballet ostriches of Fantasia, they鈥檙e wild animals that, despite deep social instincts, are perfectly capable of pecking their siblings to death when small, and that often do鈥攁 trait shared with other crane species, not to mention eagles and egrets.
For all the cranes鈥 seemingly human attributes鈥攖heir voices change as they age, they paint themselves with mud for camouflage, they even go bald as they get older鈥攊t鈥檚 the wild otherness of the birds, as with all wildlife, I try to honor. At the same time, it isn鈥檛 only wild otherness that sustains them. There are 10 times more sandhill cranes along the Platte now than there were in the 1940s (an astounding 500,000 birds); sanctuaries, river management, and vast fields of corn help explain the population explosion, though the flipside of the agricultural bonanza is the diversion of water that, in the Platte, used to flow far wider and far faster, scouring its islands clear of bushes and trees, which was essential for keeping the river a suitable roosting spot for skittish birds ever on the lookout for coyotes and other predators.
Today heavy machinery clears islands in the Platte once scoured by spring floods, work that 约炮视频鈥檚 Rowe Sanctuary undertakes at vast cost, along with its education and conservation efforts. Nebraska, its highway signs inform me, is 鈥淗ome of Arbor Day,鈥 but sometimes removing trees is as environmentally important as planting them.
This is something Bill Taddicken, Rowe Sanctuary鈥檚 genial, mustached director, understands well. I meet Taddicken at the Best Western Mid-Nebraska Inn and Suites in Kearney, where I鈥檓 staying with other crane enthusiasts. He鈥檚 briefing us for an evening in the blinds. One of the things I admire endlessly about men like Taddicken is that鈥攁long with running an education center, recruiting volunteers to help shepherd 15,000 birder-tourists who come each spring, fighting water diversion projects without alienating farmers, raising money for farmland that might be added to the sanctuary鈥檚 patchwork plots, and a host of unglamorous bureaucratic tasks that go unsung into conservation鈥攈e still breaks into a broad grin when describing crane migration. He all but bursts into poetry as he evokes that first glimpse of birds descending鈥斺渓ittle specs out of the ether鈥 that grow more distinct and more numerous until they come down as if 鈥減oured out of a bucket.鈥 Their landing, however, is delicate: 鈥渓ike a dandelion seed coming down.鈥
Soon we are in a blind鈥攁 little wooden hut the size of a one-room schoolhouse, with small, square, head-high openings chopped out for viewing. The blind is perched right above the Platte, and we can see and hear the river rushing. The sun is still going down鈥攊t鈥檚 important to be in the blinds early so we do not spook the birds; we will creep out after dark, when the cranes have settled in the river, where they roost midstream. Camera lights are taped over and I haven鈥檛 even bothered to bring mine鈥攚ho wants to be the guy with the accidental flash who sets off a chain reaction that incites 20,000 birds? It is, besides, a gloriously documented spectacle.
The birds are already filling up the fields beside the river, where many thousands are gathering; they鈥檒l transfer en masse to the river once it gets dark. And suddenly it is dark enough and the cranes begin to come. These are not the roadside birds I saw on my drive, 200 yards off the highway. Their wings are as wide as I am tall; their bodies are as long as my eight-year-old daughter. Their stick legs, stretched behind them as they fly, drop under them like landing gear as they come down. I am a guest in their world now. It鈥檚 their highway I鈥檓 parked beside.
There are so many of them, circling, landing, shaking their bustles, taking off again, flying into and out of and through the restless merging flocks, that it is hard to focus on any one individual. I feel like a dog chasing too many rabbits. Looking left and right there are perhaps five miles of river in view, which according to Taddicken can hold about 100,000 birds.
Strangely, this gives the stretch of river something in common with Central Park in Manhattan. It was the superabundance of migrating songbirds that knocked me over when I first began birding there; only later did I learn that, because birds flying over modern cities have so few green options, it was an artificial profusion, creating a false impression about the global health of birds. In Nebraska there used to be about 200 miles of river suitable for cranes whereas now they鈥檙e crowded into a 50-mile stretch between Grand Island and Kearney. Thanks to numerous dams, only about 30 percent of the Platte鈥檚 water makes it as far as the Rowe Sanctuary, limiting the cranes鈥 habitat even more.
No great natural spectacle comes without a political or a philosophical backstory. How many cranes should there be? Several states now either allow a hunting season or are debating one鈥攁nd without question sandhill cranes have made an extraordinary comeback. Of course some populations do better than others, some migrate, others stay put and are more vulnerable. How permanent is their newfound success鈥攄ependent as it is on strenuous conservation efforts and an uneasy alliance with farmers鈥攁nd how vulnerable is a population of huge birds that produce only one or two young a season, and that must hopscotch over ever-urbanized migratory pathways? These questions are important, for they explore how fully cranes鈥攁nd all birds, really鈥攍ive today inside the artificial world. The wide, fast rivers that once sustained the cranes will never be returned to them. Their ability to be wild is a test of our ability to manage the world we have altered, which is to say it is a test of our humanity, and so we are bound together, needing each other in complex ways we鈥檙e only beginning to understand.
The noise surprises me, as if I鈥檇 imagined migration as a silent movie, but the birds call to one another constantly, a cacophony of loud croaks and cries.
鈥淐up your ears,鈥 whispers Taddicken. I go farther and close my eyes.
Each complex, trilling call, strung out of beads of sound, can carry for a mile and seems both high and low. The cumulative effect is like thousands of ancient doors creaking open, as much vibration as voice, echoed not only by the rushing river but your own blood.
Suddenly there鈥檚 nothing scientific or ornithological about my observations. I鈥檓 part of the flock, and I understand an aspect of Great Plains mysticism I often encounter in Nebraska writers as disparate as Willa Cather and the scientist Loren Eiseley, whom I read as a boy, not realizing he was from Nebraska until Matt Harvey from the gives me a copy of The Loren Eiseley Reader. In that collection there鈥檚 an essay in which Eiseley strips off his clothes and floats in the Platte River, despite his terror of water after a near-drowning accident as a child. Eiseley lets the broad, shallow river, famous for quicksand, take hold of him, and has 鈥渢he sensation of sliding down the vast tilted face of the continent,鈥 feeling a kind of ancient earth memory more in tune with native American religion than the detachment expected from an anthropology professor.
I emerge from the blind with my senses confused. The wind has kicked up, the clouds have obliterated the supermoon, but the superbirds are still aloft, making a racket. As we file out quietly to crunch across a field and back to our cars in cold darkness, temperature plunging, thousands of cranes are streaming restlessly above us, dark shapes against the deeper darkness of the sky. They should have roosted by now, but there鈥檚 a kind of anxious tension in the air. I lie on my back and look up, feeling like Eiseley in his river, but it鈥檚 a river of birds.
The birds settle down eventually; when we return to the blinds next morning before dawn, we find the cranes crowded on sandbars in cocktail party clusters or standing in water up to the knot in their long legs that looks like a knee but that, in one of the quirks of avian physiology, is really an ankle. The cranes seem calm in the pale light. A bird raises its wings in a sort of lazy flap, almost like a yawn, before rising into the air; others seem pulled after it by invisible strings, though there鈥檚 no hurry. Some land again, and those that don鈥檛 circle the river several times before flying off. High above them, the brightening air is full of milling birds as if someone had stirred the sky with a stick.
There鈥檚 more to see as the sun comes up鈥攁 log floating past that turns into a beaver; some coots, a muskrat by a clump of reeds鈥攂ut I miss the thrumming frenzy of the night before. The rest of the world returns to focus. Two power lines stretched across the river take a toll of crane lives every spring but cost too much to bury.
Outside the blind I meet Michael Farrell, who produces documentaries for Nebraska public television. Farrell informs me that the birds were restless the night before because the river, often too low for the cranes, is too high for them now鈥攖here was 40 percent more snow pack in the Rockies, which meant an opening of dams to make room for the increased melt, which in turn raised the level of the river, a chain reaction of man and nature that affects the crane鈥檚 roosting habits.
Farrell has a grizzled moustache, glasses and a mixture of outdoor unpretentiousness, activist outrage, and professorial intensity not uncommon among the environmentally engaged. He pours out a dizzying array of Nebraska history, the sorrows of the Oregon Trail that sowed cholera for Native Americans, the fierce community battles that began in the 1970s over water diversion along the Platte, something about the Salt Creek tiger beetle that I don鈥檛 entirely catch. Farrell also tells me that for the past 13 years he鈥檚 come to Rowe Sanctuary on the first day of spring, ever since he and his family scattered his wife鈥檚 ashes from the blind we鈥檝e just been in. His wife loved the annual migration and had said to him, as she was dying, 鈥淩emember me when the cranes come.鈥
It is, I realize, the first day of spring. And I realize that a blind for bird observation can also be sacred space. It is a humbling recognition that reminds me to look at nature鈥攁t everything, really鈥攖wo ways, attuned to the practical, political, and scientific and, at the same time, the mysterious, the personal, and the beautiful.
On my drive back to the Omaha airport, I stop at a field a few exits off of I-80, not far from Kearney. I鈥檝e received a murmured suggestion, more like a gambling tip, that I look there for a 鈥渂ig white bird,鈥 code for a highly endangered whooping crane. Like sandhills, whoopers are an ancient species but proof that nature does not have a first hired, last fired policy鈥攖here were only 15 individuals in 1941, and even today, after vigorous conservation and breeding efforts, there are fewer than 400 whooping cranes left in the wild.
Just as sandhills are the most numerous, whoopers are the scarcest of the world鈥檚 15 species of cranes, but the two species overlap at various points on their journey, and just a few weeks after I leave Nebraska, 11 are seen in the Platte from the blinds at Rowe. I鈥檝e long wanted to see whooping cranes, snow-white birds with black wingtips that, at five feet, are the tallest North American bird, as well as one of the rarest. It is because of the whoopers鈥 endangered status that Federal money can be used to maintain the Platte, which in turn benefits sandhills and other species. It is the whooping cranes that carry their far more numerous cousins on their endangered backs.
I fail to find the whooper at the designated exit, though there are plenty of sandhills grazing and flapping. Nothing demotes a magnificent bird faster than redefining it as 鈥渘ot the bird I鈥檓 looking for.鈥 Still, I know I will pine for these birds as soon as I鈥檓 back in New York. And both species should be held together in the mind, the white bird somehow the shadow of the gray one, a reminder of the threat of extinction in the midst of abundance, and of the double vision required by birdwatching.
