Synopsis

In this extraordinary journey, Alan Tennant recounts his attempt to track the transcontinental migration of the majestic peregrine falcon — an investigation no one before him had ever taken to such lengths. From the windswept flats of the Texas barrier islands to the Artic and then south again into the Caribbean, On the Wing provides a hilariously picaresque and bumpy flight.

Excerpt

PARTNERS

Trailing steady electronic beeps from the tiny transmitter glued to the base of her tail feather, the peregrine quartered tentatively up Padre Island's barrier beach. A tundra falcon, a barren-ground hunter born in the Arctic, she had for the past two weeks cruised with increasing randomness up and down Texas's offshore islands, seemingly reluctant to leave the windswept flats for the alien greenery of the mainland. But today the springtime stream of tropical air welling in from the Gulf of Mexico had gripped her in its northerly flow, and after a final sideways cast along the surf she swept inland, away from the sea.

"She's migrating," called Janis Chase, the military attaché in charge of our radio-tracking flight. "I think she's on her way!"

From 2,000 feet up, in the rear seat of our single-engine Cessna Skyhawk I watched the Gulf Coast's shoreline dunes give way to bluestem pasture, and gradually the magnitude of what we'd chanced upon sank in. With no companion, guided only by the ancestral memory she somehow carried within, our little hawk was staking her life. Nothing like the abstract idea of migration that I'd imagined, it was humbling even to be a spectator to the mortal intensity of what the tiny, determined speck below was doing. On that sunny coastal morning she was committing every ounce of will and spark of force that flowed inside her to a race toward home. I tried to imagine what could be going on behind her fierce eyes. Some inner vision, I guessed: a tucked-in cliffside ledge, set above the tundra, with long-unseen domestic details of surrounding rock and bluff-face. Maybe its sounds, too: the whistle of arctic wind, and in the suddenly still air, familiar birdsong, the croak of ravens, or the scream of rough-legged hawks nesting nearby. No one would ever know what she thought, but it was clear that as we watched, something had swirled to life within the soul of this falcon, becoming the driving force of her entire being.

At the time, during the mid-eighties, it was thought that she would travel northwest from Texas, seeking the high-altitude passes of the Rockies, then work her way up the spine of the Continental Divide. But only she knew the route she would really take, or where it might eventually lead. And only she would ever know if that knotted force of will-the power that was now sweeping her along at mile-a-minute speeds-would be enough to carry her there. Enough to lift her up, buoy her over the third of the planet that lay to the north, and then deliver her, perhaps weeks from now, onto the coal-shale crags of the Arctic. There, more than 3,000 miles from this humid Texas plain, on some late spring day the ledge where she herself was born might once again appear beneath her wings.

"That's enough," Chase ordered our pilot, George Vose. "I've got my departure vector; it's all we need."

Chase bent to her U.S. Army Chemical Warfare clipboard, whose logsheet had a heading for "Migration Route." On it she recorded the date, the weather, and the north-by-northwest compass heading that this falcon, the last of seventeen transmitter-bearing peregrines she had been assigned to monitor, had chosen as it left the Gulf's barrier islands. While Janis wrote, for a few more minutes Vose flew on. I could see that-even though we knew her mostly from her relayed transmitter signal-it was hard for him to leave that flickering speck of brown below, now embarked on a lonely quest toward her unknown, almost inconceivably distant home.

Then Janis looked up and motioned for George to turn. Reluctantly, I felt, he banked us slowly around, descending across the bay to Cameron County Airfield and what had suddenly become a far smaller world.

Smaller because, even with my daily chance to capture and band peregrines as a visiting helper attached to a peregrine research team, seeing the metamorphosis that migration had brought about in one of the falcons whose kind I'd watched, and even captured on the tidal flats, was astonishing. Afterward, Padre's peregrines were no longer simply beautiful raptors to be lured in for banding. They were part of something larger. Something ancient and powerful. Global as the tides, though at the moment all I could think of for comparison was gazing, as a kid in the Port of Houston, at ocean-going tankers from Liberia, freighters from Singapore and Seoul, Buenos Aires and Dakar-places I knew about but never hoped to see.

What was frustrating was that it was clear we had not really needed to turn back. With our powerful military receiver I was sure we could have gone farther: just kept on, maybe for days, aloft with one of these radio-tagged falcons.

But neither Janis nor her tightly managed military program would ever make that choice. Chase had been assigned only to determine what percentage of the arctic peregrines, Falco peregrinus tundrius, that migrated up from the Tropics every spring then traveled northeast from the Gulf Coast. Presumably toward the cliffs of Greenland, most of these continued on. Others went west, maybe to Alaska. As only a falcon-trapper's helper, with no role at all in Chase's study, I was lucky to have maneuvered my way onto even a single radio-tracking flight, and though I desperately wanted to go up again, Janis's program already had its data. She was scheduled to move on to another assignment, and today was her last mission.

Maybe, I offered, I could keep flying with Vose-a long, silver-topped column of a man people took for Janis's dad-filing more logbook statistics. But Janis made it clear that after she left Padre the Army wasn't leaving its sophisticated radio-tracking gear with anyone. Especially, I gathered, with either George or me.

Though the military had rented Vose's little plane, to the project's buttoned-down young administrators George hardly could have offered a less compatible job profile. As a World War II combat flight instructor, a generation older than even the parents of his Army supervisors, he'd logged more wartime military years and on-the-edge long-distance, light-plane aviation hours than all his bosses put together. But beyond his occasional mention of his barnstorming years, none of them knew anything about Vose's past, since they'd hired him principally because he was the only telemetry-experienced pilot willing to accept the low-paying charter Janis had to offer.

George's penchant for talking freely about his work also meant he was seen almost as a security risk, and I'd heard among the close-cropped young officers who ran the Army's program that it was necessary to keep a close eye on him, though I couldn't imagine what kind of security breach his tracing the migration route of endangered birds of prey might entail.

I didn't rate even that much attention. A lifelong naturalist, birder, and writer of herpetology texts, I was no more than the friend of one of the program's directors, Kenton Riddle of the University of Texas's Bastrop Science Center. I had managed to hitch a ride on the radio-tracking plane only because storm's had flooded the mudflats where we trapped the Army's study peregrines. But after that first flight I couldn't get the falcons' journeys out of my mind, and when Chase left Texas two days later, I saw her onto the flight back to Patuxent, Maryland, then drove over to Laguna Vista Airfield. Vose was stitching up the sagging cloth of his Cessna's headliner.

"Customs men," he grumbled. "United States Customs. Slipped out while I was doing their durn paperwork and cut up my plane. Looking for drugs."

He poked his needle into one side of a long slit.

"Wouldn't put it past 'em not to make sure they found some, too."

I examined the Army's yard-long, Christmas-tree-shaped antennas, which George had cobbled onto the Skyhawk's wing struts using hollowed-out chunks of 2 ¥ 4 and a snarl of radiator-hose clamps. A little scary, but with no pilot's license-never having even flown a plane, of which I was semi-terrified-I wasn't in a position to be choosy.

"Ever think about keeping on?" I asked him. "Just stay up there with one of these falcons?"

Vose said he'd thought about it. A lot. He had even followed some, over longer distances with earlier researchers, and with Janis. He jerked his thumb at the Cessna's backseat, where three Army radio transmitters lay swaddled in bubble wrap.

"Still got some radios. . . . But what I'm saying is, this little Army deal's just nothing. Not even real aviation."

It took Vose more than a moment to swing his big frame down from the plane, but he wasn't finished.

"Lemme tell you. . . . After the War, one of the things I did for a living was go into crash sites. Just one helper. Build us a board runway, right on the ground: eighty yards long. Then we'd mechanic that aircraft back together and fly it out."

He looked at me closely.

"Certainly I could keep on after one of these little things."

I raised my brow.

"Clear across the country?"

George put down his needle and fishing-line thread.

"Any country in the world-falcons only average fifty or sixty miles an hour."

Anywhere in the world. I took a breath. Vose couldn't know it, but since our first flight, the idea of following one of these creatures, wherever its airborne life might lead, had become the grandest idea I'd ever had.

George shook his head.

"Military won't approve it," he said. "They're waiting for a satellite-due out sometime in the nineties-that can track these little transmitters." I pictured an electronic warren, glowing with data screens and keyboards, where some technician sat, coolly plotting the intercontinental flights of real flesh-and-blood peregrines as they streaked from tropic jungle to arctic steppe. By then, Vose and I and his little Cessna would be irrelevant.

Yet for a while now we still had a chance to be of consequence. If what George said was true, we really could go up with a peregrine, fly with it, and, while mystery still cloaked its realm aloft, share the primeval momentum of its dream, or instinct, or simple fancy.

I just didn't know how much any of that might mean to Vose.

He was an aviator, not a bird guy, so maybe not much. But he had definitely been disinclined to let that first peregrine go. That and not having to watch from the sidelines as his share of aviation dwindled into technological irrelevance might-just possibly, I hoped-be enough to draw him into what was becoming my own overwhelming vision.

In any case, it was now or never. I took another breath.

"How about . . . well, why not try it on our own?"

George put his sewing gear back in the toolbox.

"These birds are protected; some of 'em endangered. Army'd never give us permission. . . ."

I looked dead at him.

"Of course they wouldn't."

Vose turned away, and I was sure I'd lost him. I had barely met him, and there was absolutely no reason for him to defy his military employers in favor of a semi-illicit trip with me.

For a while he studied the Skyhawk's stitched ceiling, which now resembled Frankenstein's forehead. Then, in the same careful way, he looked me over, stroking his mustache. It was thin, white, and pointy-Errol Flynn style-a holdover from his adventure-flying days.

"Aviation takes intestinal fortitude, Mister. You were pretty green up there today. Calm air, too."

From a battered leather suitcase George dug a roll of orange surveyor's ribbon.

"I don't do this," he explained, draping the pointed prongs of the Army antennas with florescent streamers, "somebody'll kill themselves and sue me." He looked over. "Can't think why you'd want to follow a falcon in the first place."

Want to? Follow a peregrine, maybe all the way to its polar breeding ground? No one had ever done such a thing. But I was talking to the one man in the world who could.

I caught George's eye.

"Same reason you'd want to," I said.

Above the Skyhawk, big white cumulus were building, and to avoid each other's gaze we both looked up at them.

"Go," I said, "where no one's ever gone."

"Ever known how to go," growled Vose.

But I could see his doubts. I was some kind of bird nut: no idea what kind of down-and-dirty flying my idea called for. Still, paying jobs in aviation didn't come often to a guy in his sixties. Late sixties. Bad knees, shaky hands. Gin-and-tonic more often than every now and then. Plus, this Army deal wasn't just discouraging; to a real flier it was almost an insult.

"We'll never get this chance again," I said.

Vose scuffed a foot.

Just barely, I could see a crinkle crease the corners of his pale blue eyes. He stepped back from his ribbon-draped antennas, stowed the roll of tape, and rooted through his leather case. Finally he pulled out a black plastic garbage bag.

"Here," he said, pointing at his throat. "Buy you some of these. Just in case."

At my grin he darkened.

"Now we're only doin' this, Mister, no more'n a couple days. Tops."

PADRE

Forty-eight hours later, gassed and as ready as its rattling old motor was ever going to be, Skyhawk '469 sat by the flight shack at Cameron County Airfield. I already knew my new partner would be inside swapping stories with anybody who even looked like they might have once flown a plane, while he waited for me to call and report that I'd captured a peregrine falcon and put one of these leftover Army transmitters on it.

Not that I was very likely to. I was camped up at the far end of the barrier island, smack in the path of the tundra falcons' spring migration route, but so far I'd mostly just watched as Ken's trappers captured peregrines. I had studied the team's trapping equipment, though, and since I'd hooked up with Vose I'd made my own rough copies. But I still wasn't sure exactly what to do with them.

The biggest problem was that during three days alone on the flats I had seen nothing resembling a peregrine. Then, before first light on the fourth morning, I smelled the mainland. I'd been on Padre long enough to know that meant an onshore wind was pushing out from the coast, ahead of a late-spring cold front. Soon, rain would force the shorebirds into the shelter of the reeds, and the falcons would press for an early kill while their prey was still exposed.

It was their way. Fierce wild spirits so briefly seen as to seem more apparitions than real birds of prey, peregrines hunt at the edges of the day, when their enormous, light-gathering pupils give them an edge over small-eyed wading birds unable to fly well before first light. Seldom relaxing like other hawks in idle floats across sunny summer clouds, Padre's peregrines hid in the diminished perspective of distance, hanging far away, on the air, or crouched on the remote, empty flats, picking out prey birds with the uncanny acuity of their binocular vision. Then, concealed in the dimness of dawn or dusk, with a rush of their long wings they would come flaring in, cutting open a sudden tumult of waders flailing into the air, then forever shutting off for one of them the open sky and the hiss of its companions' panicked wings.

Author Q&A

A Conversation with Alan Tennant

Q: Okay I have to begin with the obvious: You risked your life (not to mention your relationship, reputation, and bank account) and broke countless laws to follow peregrines on their global journey (a task nobody had ever undertaken) in a plane you describe as looking “like a big plastic strawberry box.” Why?
A: People had followed peregrines with aircraft before, getting the basic direction of their migration departures, but no one had kept on so far with a falcon--and never with the unshakable goal of staying with it for as long as its global journey lasted. No matter what authorities had to be defied, whose telemetry equipment had to be swiped, which
international borders had to be crossed, legally or illegally, and what local police and military forces had to be evaded, I was determined to achieve that goal. To do that along with me there was only one man with the flying skills, guts and gumption--George P. Vose. His old Cessna's fragile, plexiglass-sided cockpit did indeed remind me of a big strawberry box.

Q: Was there ever a moment when you thought to yourself, “Okay this is it. I am not going to survive this trip.” Tell us about some of your more dangerous escapades and what went through your mind during those moments?
A: There were probably not more than a couple of days, in all the time Vose and I followed peregrines that, at some point I didn't think, “This is it. We're going down!” Those times started with the dense Gulf Coastal fog George and I had to fly through behind our first falcon, sometimes swerving between Texas' radio beacon towers like a ship in a video game. At other times, though, the plane's problems were hilarious. Arriving in Denver, we discovered that--with only one wheel able to brake--we could only turn left, which meant we had to detour, left turn following left turn, all over the airport's many runways, keeping a squad of passenger jets circling overhead. Then there was the Rocky Mountain meadow we barely got out of by banking, halfway through take-off, down a slot between its bordering Douglas firs. There was the ice storm in northern Montana and the time our single carburetor fell off over southern Canada. Plus my crash in a bush plane (not piloted by George) on the banks of an arctic river. It goes on from there--I don’t want to give too much away! --but let’s just say there was an episode that resulted in Vose and I looking down the barrel of a cocked .45 on a drug smugglers' hidden airstrip.

Mostly what I felt during all this was unmitigated terror, except for our last engine failure, when a distant mud spit offered an opportunity not to crash into the sea. Vose wouldn't try a landing there, and I was furious. As the suddenly silent plane fell, we had a huge fight until I realized that terminally crunching his old Cessna on that spit of mud would leave George, like one of the flightless hawks I'd spent my life caring for, forever without wings. It was his choice, and as his partner, it became mine as well, and with little airspace to spare we made it to the last offshore island of solid ground.

Q: How did you first become interested in falcons and what do you think has made them, through the ages, creatures of such reverence and fascination?
A: As a tiny child I was fascinated by hawks soaring overhead. That interest faded, however, with visits to the caged birds of prey in our nearby zoo who, kept away from the sky, were so clearly sullen and miserable. My interest did not rekindle for years--not until I realized the incandescence that lay within every raptor.

When I was twelve, my Dad shot a hawk. Knocked it out of a tree at a hundred yards with an iron-sight Remington 22. My Dad, brother and I scrambled out of our canoe to get it and when my father stooped to pick it up, its eyes flared and it scythed three talons completely though my father's hand. He screamed and ripped away the claws, but the hawk was ready to fight again. Nothing had ever stood up to my Dad! Not even Blackie, his angus bull; certainly not my brother or me. That sort of fearlessness -- along with their unmatched aerial ability -- was what made birds of prey, and falcons in particular, a sort of ultimate icon to each of the many societies that revered them.

Years later, after I'd become Co-Director of the Raptor Preservation Fund, with a big house that sheltered a dozen hurt hawks, I still had that gunshot red-tail's flashing eyes in mind. But the birds of prey around me were hunting birds forever cut off from the sky. That’s why the chance to go aloft, no matter what the cost, and travel with the ultimate raptor, meant so much.

Q: A lifelong naturalist and birder (not to mention hurricane chaser) one can see how you would be drawn to this task. What do you think drew George Vose, your partner-in crime to the journey?

A: George Vose has been flying since his teens and was a 20-year old Air Corps combat instructor during the Second World War. After the war, he was one of he few guys who'd go into remote areas to rebuild crashed aircraft and fly them out on makeshift board runways. Also a stunt pilot and the former owner of his own flight school, when I met him George was living in a twelve foot-long aluminum trailer, far out in the West Texas desert, next to a box of hand built adobe walls that despite the fact that he'd been working on his house for ten years were only four feet high and crumbling (an archaeological expeditionhad taken them for a pueblo ruin). Nobody knew George's past. He still had the fire, though flying jobs don't come often to guy like that. Late sixties, bad knees, shaky hands, gin and tonic a good deal more often than every now and then.

When I asked him to join me I said, “We'll never get this chance again.” I knew he thought I was some half-baked bird nut, but he couldn’t resist a chance to once more take off on the sort of long distance adventure flying he'd made his name with.

Q: As a matter of background can you give us a summary of the peregrine population over the last several decades?
A: Before the Second World War's introduction of DDT for mosquito control, the worldwide peregrine population was probably not far below its historical high. But as DDT became universally employed as a pesticide during the 1940's and 50's, more and more insects became resistant to its effects, and, carrying formerly lethal doses of the chemical in their bodies, a lot of those bugs lived long enough to pass those toxins up the food chain to the songbirds that fed on them. Here, both DDT and its metabolic derivative, DDE, were concentrated in the insect-eating birds on which peregrines preyed. Among these falcons -- long before an individually lethal dose was reached -- first DDE, then dozens of other man-made environmental contaminants inhibited the transfer of calcium from the wing bones of breeding females to their forming eggshells, leaving them too thin to support the weight of their brooding parents and crushing the developing chicks within their shells.

By the 1960's, peregrines were extinct east of the Mississippi. A diminished population hung on the less heavily sprayed western mountains, but even the arctic peregrines -- a separate subspecies known as Peregrinus tundrius -- were beginning to show signs of eggshell thinning due to chemicals carried north from their wintering grounds in Mexico and Central America. After the US, in response, banned DDT, Cornell University's famous Peregrine Fund, under the direction of Tom J. Cade, began its innovative captive breeding and reintroduction program, and as a result both eastern and western peregrine populations have staged dramatic recoveries. The arctic tundrius, meanwhile, though still faced with local eggshell thinning, is now no longer a threatened race.

Q: How did it come to pass that both the University of Texas Cancer Center and the Army teamed up for The Peregrine Project?
A: How the Army and the Cancer Center got together on the Peregrine Project is known only to the top brass in each camp. Nevertheless, one of the Army's several roles was to pick up a large share of the program's considerable expenses -- not only paying Vose's aircraft charter fee, but using big military-transport Chinook helicopters to ferry falcon trappers, hundreds of bait pigeons, a dozen or so all-terrain vehicles, and huge amounts of equipment, including a portable gasoline depot, back and forth to the offshore islands, as well as housing its highest ranking personnel in top floor condominiums in the resort town of South Padre Island. The leaders of each camp were, I think, fundamentally both avid falconers and falcon researchers who wanted to spend more than a month each spring and fall trapping migrating peregrines. Justifying the cost of the major expedition this entailed, however, meant convincing the Cancer Center of peregrines' value as environmental monitors. That is, creatures who, because of their position at the top of the avian food chain would -- like canaries in the early coal mines -- concentrate enough toxins in their bodies to warn of impending bio-hazards.

Where the Army was concerned, beyond its directors' interest in falcons, there were other, more enigmatic reasons for being on Padre. Nothing was ever discussed much, but most of the military researchers were part of the federal chemical warfare program and swapped stories about the animals-as-saboteurs conferences they'd attended. Often, they spoke of peregrines -- once their international migration routes were clearly mapped -- as both covert monitors of other nations' air space and mobile vectors for sensitive listening devices. I don't know if anything ever came of their ideas, and suspect that spy technology has by now bypassed falcon-borne monitoring devices, although current migrant peregrines sometimes carry the much larger and more complex, backpack style, satellite-received transmitters the original project's Army guys looked forward to obtaining as information-gathering devices.

Q: What did you hope to learn, on your travels, that would have practical applications to preserving the future of peregrines?
A: At first, the simple drama of following a migrating arctic falcon--accompanying it all the way to its unknown home on the polar tundra--was such a magical idea that I was entranced. Later, though, during the fall migration, what came up as a more particular goal was the mystery of why so few young peregrines show up on the barrier islands the following spring. I knew that George would be fueled up and ready to take off, and that if we could get behind any of the young peregrines I'd just gotten transmitters on we might be able to discover why so many of them failed to return to Padre. The reason might simply be storms, bad weather, scarce prey. But if it was something artificial--of human/chemical origin -- then it was likely to be something that could be corrected. After our weeks spent following Amelia, Vose and I discovered that the greatest hazard our young birds faced might be the miles long chains of enormous, open oil tanks filled with petrochemical sludge by the Mexican petroleum industry. These vast shallow lakes had chemically saturated margins where tens of thousands of shorebirds stopped to feed, picking up toxin-laced invertebrates whose poisons they were sure to then pass on to the falcons who found sick and weakened individuals easy prey on the tanks' barren perimeters.

Q: You write, “It matters when technology obliterates not just the life but the heroism of other species.” What do you mean by that?
A: The death of almost every adult individual, of any species, in the jaws or talons of its natural predator is, in its essence, heroic. A struggle fought on the basis of the individual's natural defenses, however agonizingly its life is ultimately lost, is lost on the failure of the creatures' evolutionarily acquired defensive qualities. For example, a majority of the birds pursued by peregrines use their innate gifts of speed and evasiveness to simply out-fly the falcons. The ones that do not get away nevertheless make heroic efforts to escape, and die having spent their last remnant of strength -- yet simultaneously feeding the life of their captor. A bird swept to its death by a mechanical contrivance, however, is killed by a device against which it has no innate defenses.

In On the Wing, this is the thousands of songbirds smashed by high speed vehicles rushing directly across their low level landing trajectories on the Texas shoreline -- these are denied the chance for a natural, even heroic death and the nutrition that their bodies would normally have passed along to their predators end up rotting on the grills of the pickup trucks and SUVs speeding down the Gulf's coastal highways -- land that the birds have reached only after a heroic flight across hundreds of miles of open ocean.

Q: One cannot talk about the power of flight without thinking that George is very much like Cherokee, Amelia, and all the others "who flew with the wind in their souls and the tactile power of slender wings immanent in their limbs.” What about flight made it so essential to George?
A: Flying, to George, was aviation before technology made it an exercise in electronics -- a time when you flew, like our peregrines, with the feel of the wind in your wings and tail. Partly that was purely practical. Aviation was one of your choices as a young man, in Maine, during the thirties, and Vose had done it right. Chosen a reliable tool, a standard, single-engine light aircraft, and like someone learning to use a complex lathe or harvest combine or diesel fishing boat, he had made its technology his own. Made it, to him, a commonplace.

Prosaic as Vose tried to make that sound, his commitment to flight had a more romantic genesis. The first aircraft he ever saw was a bright yellow biplane that buzzed around his second grade classroom in Machias, Maine, one morning in 1929. Despite his teacher, George hung on to the windowsill and counted as the pilot did twenty-seven loops in a row. After that, it took five years of Depression era nickels and quarters to get the $5.50 fare he split with another kid -- the two of them being light enough to qualify as a singlegrown-up--to go up from the hayfield landing strip where barnstorming flyers came through selling rides. Wedged into the front seat of an Eagle Rock double-winger, George knew he'd found his life's pursuit.

Q: You write that yours and George’s journey, like that of the peregrines, was "a testimony to the optimism of life itself." How do you feel your life has been different in the years that have passed since you took your last trip aboard old ‘469?
A: Since George and I flew with peregrines, life has been different. Not necessarily more optimistic, but certainly larger. Even on our first flight together, while his military employer recorded her data, for minutes after she'd told him to turn back, George flew on. I could see that it was hard for him to leave the falcon flickering along far below, now embarked on her lonely quest toward some unknown, almost inconceivably distant home. Then his Army boss looked up, and in irritation motioned for George to go ahead and turn. Reluctantly, he banked us slowly around, descending across the bay to Cameron County Airfield -- and to what had suddenly become a far smaller world.

Q: Did you ever cross paths again with any of your peregrines?
A: Unfortunately, I never again crossed paths with any of our peregrines. In one case, though, I barely missed it. After Vose and I left Belize, Airport Manager Luis Alpuche, now with our left-behind scanner abuzz on his desk, could hardly help but have his
curiosity piqued by the potential passage of the falcons that we had told him might some day come within range of his receiver's control tower-mounted antenna. Weeks later, in the vicinity of the airport Alpuche began picking up transmitter signals possibly from Anukiat, maybe even long-vanished Delgada, since her frequency was also still in the receiver's search band. I caught the first flight for Belize. But before I arrived the signals had disappeared, and on numerous subsequent trips, though I found other peregrines, I never picked up one of our falcons' signal.

Q: What is George up to these days?
A: Finally, George Vose didn't go down with his plane. But he did return to Mexico, working for U.S. Fish and Wildlife. During the mid 90's he went back to monitor flocks of white-fronted geese that, radio tagged in the Arctic, migrate to a winter range around Chihuahua's 7,000-foot-high Laguna Bavicora. Vose was seventy when he started the goose project, and Fish and Wildlife thought he'd never stick it out at Bavicora for five whole winters. But he did, despite being snowed in for more than a week on a couple of occasions. Then George hooked up with a bear. A big, black male who climbed a tree next to the County Courthouse in Alpine, Texas. But that’s another story, which I tell in the epilogue to On the Wing.

Q: So we know that Robert Redford will be playing George in the film version of your book.. Who do you see as Alan Tennant?
A: Ben Stiller; Brad Pitt.

Author Q&A

Meet the stars of On the Wing

Amelia
Amelia was the first peregrine we followed all the way north. As she grew restless with the lengthening days of approaching summer, we could see a change come over her. Yet long before she left the hunting flats of the Texas coast, I wondered why she sought the vultures' thermals every morning, riding up thousands of feet, where she’d never ventured? And why go higher every day? All Amelia could find up there were vantage points--ever loftier aerial sites from which her laser eyes could pick out the upthrust highlands that , 100 miles inland, would guide her north. Within her there had to burn a force. Some guiding image more ephemeral than a blueprint of the genes, something more dreamlike than memory--but some awareness, some close-held picture of a rocky, cliff-side place not far from where she herself had hatched.

Gradually the pull of that distant prospect must have swum into focus, pulling her up toward the heights she would need to vault the continent. And somehow, we had managed to be with her at the moment when that primal vision at last exploded across her consciousness, spinning her away like a bright spark flung from the circling vultures. Wisps of chocolate cloud, the last of their flock swept beneath our wings but, five miles ahead, Amelia was already changing -- not just choosing her course of migration but starting to remake herself. As the minutes passed it was like seeing a butterfly slough its gray-shroud chrysalis, for with every mile Amelia was creating a new winged being. The mostly idle, afternoon-dozing little hawk George and I thought we knew so well was leaving us, becoming an unfamiliar 30 ounces of singular purpose. Stroking deeply and steadily, she swept past the shoreline and, focussed now on lands far beyond our accustomed coastal haunts, like a departing angel she pressed on toward those distant highlands. It was what I'd glimpsed on my first radio tracking flight with Vose--the primordial flame of which we'd had only a vague idea when we chose it as our beacon. Now, caught in its power, George and I exchanged a look. Locked on this heading, Amelia had committed herself to the western fork of the tundra peregrines' long highway home. If she lived, with or without us she was going to Alaska.

Crazy Legs
Crazy Legs was, for a while, Bill Satterfield's pride and joy. I'd been at Padre when she was brought in, and like many of the newly flighted youngsters that arrived on the barrier islands, she was thoroughly beaten up. But Crazy Legs, as we called her for her twisted, previously broken left leg, was worse. Somehow she had made it down from the arctic on wings gapped by the stubs of missing flight feathers, likely broken from tackling too large prey, and in desperation she had come in to one of our pigeons. Satterfield, who was both a vet and a student of falcon ecology, wasn't optimistic. "Even if she lives, I can't see her defending a nest ledge. And she doesn't reproduce, statistically she's a questionable member of the population." On her carpet covered perch, C.L. could not even look at us. In the Cyclops's cave of beach cabin, just the sight of her lumbering captors would have provoked constant, panicked flight, and in the darkness of her hood she could only bend to pick at the bits of pigeon breast we slipped beneath her toes. Otherwise, she did not move. Satterfield was able to stand that for almost two full days. Then the scientist in him capitulated, and to soothe away her fear Bill knocked off his trapping. His work began at night. An hour after the rest of us had turned in, I heard him begin to cluck the low, infant feeding call peregrines use as baby talk with their mates. Mingling his counterfeit peregrine voice with the pulse of distant surf, during the long hours of darkness Bill plied his courtship, like Cyrano, from the shadows. Even with her hood removed, his small Roxanne could not see him well enough to panic, and by the third night she had begun to relax, cocking her head expectantly as he began his serenade. Deep in my down bag, I wasn't sure when I first heard her reply.

Six months later, packed with muscle built on wings held aloft by fresh flight feathers I had watched Satterfield surgically implant, Crazy Legs was ready to go. A gusty springtime wind greeted Bill and me as we pulled away from the beach house, riding slowly because he was steering his ATV with with just one hand; on his wrist, proudly hooded as a falcon in a Restoration woodcut, stood C.L. Three miles southeast he stopped, removed C.L.'s anklets, and slipped off her hood. As usual, she shook herself out and swiveled around, eyeing the vast horizon. "You're free, Gal," Satterfield said softly. C.L. looked down and nibbled the place on her yellow shanks where her tethers had been. Then she dropped from Bill's wrist, swooped an inch off the sand, and swept away with the wind. It had happened too quickly, and, insanely, we leapt on the ATVs and spun off after her, burning out the emotion over the sand. For more than a hell-for-leather mile we could see her flickering wings before she vanished into the mist over the dunes.

Cherokee
Once they have flown even a little, raptors' souls wed themselves to the air in ways probably impossible for humans to comprehend. Gravely wounded, Cherokee had been brought to the Austin Natural Science Center, where I worked. A just fledged red-tailed hawk still patched with milky down, he had been an easy target for someone with a shotgun who'd blown apart his left wing, right up to the shoulder. Eventually, though, Cherokee healed, and got his Indian name from the kids who used the feathers from his amputated wing for headdresses. Then, because the Center always had more hurt hawks than it could care for, he at last came home with me, and from him I learned the power of the sky. Inside my backyard's tall cedar fence he'd tear around on foot, holding out his good wing for balance, and leap up onto my wrist for his daily mice. But he never forgot what lay above. From my arm he'd cock a burning eye upward at -- as far as I could tell -- nothing. Then there 'd be the faint con-trail of a passing jet, and I'd figure Cherokee was scrutinizing the passengers in its windows. But he didn't just watch the sky; he wanted to be part of it. Eventually, helped by frantic flaps from his good right wing, he learned to reach the topmost branch of a big oak. There he would spend the day, riveting every passing jay or overflying vulture with a gleaming golden eye. But it was not enough. Every few hours the freedom he saw in other flying things would grow too much, and Cherokee would clench his straw colored feet, squat, and from his worn-bare branch, fling himself upward with all his strength. Face turned hopefully toward the firmament, he'd gain an inch or two on earth before it pulled him back, parachuting down onto the grass. Before dark, though, he'd be back on his branch, ready to try again. But here's the thing: this naive baby, who might have spent no more than a day on the wing before he was shot, then spent twelve years trying to regain the sky.

Anukiat
Anukiat got his name from what an Inupiat teenager had called me the day I left the Arctic Slope. Hoping I had drugs to trade he complimented me on my travels, grinning something like 'ungliat' or 'anukliat.' It didn't matter: peregrine means traveler anyway and now our last transmitter-carrying peregrine was Anukiat. Quasi-Inupiat for traveler. Almost a full day behind our two girls -- the pair of adolescent female peregrines we called the Ninas -- Anukiat was the last to leave the Gulf Coast on his autumn migration to the tropics. George and I were looking for the Ninas near the Mexican fishing village of La Pesca when I punched Anukiat's #.973 into our telemetry receiver. As his beeps blared out of its speaker, I dived out from under the Cessna's wing, binoculars in hand. I didn't need them. To the north, the estuary's icing of shorebirds was starting to explode. As if detonated by some silent oncoming artillery, every hundred yards a shimmering geyser of waders -- willets, yellowlegs, godwits, turnstones -- was throwing itself into the sky. As each rising fountain of birds came streaming down the beach, peppering our ears with their cries, another, closer flock would suddenly erupt -- for in the distance, on casual wings,came Anukiat.

The Ninas
As George and I flew into Mexico behind our two Ninas, I realized that, for once, following peregrines was going to be easy. Our two falcon girls just dawdled, that sunny autumn morning, back and forth across the hundreds of square miles of sorghum fields north of Lake Vincente Guerrero. I asked George to take us down to see what they were looking at and realized that, a dozen miles apart, both were patrolling the fields' hackberry borders. Those tall hedgerows would be full of finches and sparrows, but I'd started on a theory that the helpless pigeons our falcons had caught on Padre might have prompted them, in the desperation of their long migration, to look for the similar doves that would also inhabit those hedges. Then I realized that was ridiculous. Winging along below, neither falcon felt herself to be embarked on some primal quest. Each was simply exercising her newfound freedom of movement through the air, hungrily chasing smaller birds when the chance arose. The only vision of a distant Caribbean shore was mine. Yet my larger concept actually did reflect the truth of these babies' situation.

Oblivious as they were, our peregrines' survival depended on their being able to complete the enormous journey they had unknowingly set out upon. Yet, unfettered by the human burden of self-consciousness--of the future, of the slimness of their chances--as the day wore on, flying free and feckless across the fields of northern Mexico, they moved up toward the big Sierra Madre Oriental for the night.
