| The sun has just risen over the frosty brim of the
Colca Canyon, high in the Andes of southern Peru. From mountaintop
to roaring river, the canyon drops 11,000 feet, nearly twice as deep
as the Grand Canyon. As the rays begin to slant into the chasm, which
drops a dizzying 4,000 feet beneath my rocky perch, a tiny black-and-white
speck appears far below, circling and growing in size as it approaches.
An Andean condor is ascending on the first of the thermal air currents
set in motion by the morning warmth. |
| Within minutes I find myself staring into an eye of
the world's biggest flying bird. The adult male passes 15 feet before
me, 33 pounds of body supported by expansive wings reaching 10.5 feet
tip to tip. He banks and returns, white patches flashing on broad
black wings, white ruff pulled snugly over his featherless neck. His
splayed wingtip feathers make a whistling noise, not unlike wind in
a sailing ship's rigging, as they slice the air. |
| For 22 years I have been waiting for an
encounter like this, ever since my first distant sighting of an Andean
condor circling high above an ice-clad volcano in Ecuador. Though
only a dot in the sky, the legendary South American bird ignited my
imagination. Now the creature is vanishing from many parts of its
former mountain home, and my partner Mark Jones and I are here to
photograph it and learn about two very different rescue schemes unfolding
near the center of its range. |
| For many centuries the condor has been
revered by Andean civilizations, appearing prominently in pottery,
stone sculptures and even a gigantic figure etched into the desert
surface of Peru's Nazca Plains. Yet much remains unknown about the
birds. It is clear that they are formidable scavengers, the undertakers
of the natural world. They quickly clean up the remains wherever death
strikes, helping to prevent the spread of disease among large mammals
in the process. |
| At the time of the Spanish conquest, the
Andean condor's silhouette was a common sight along the entire Andes
cordillera. But habitat loss, reduced food sources and relentless
persecution have been drawing ever- enlarging blanks in this former
range map. The species is all but gone from Venezuela, while in Colombia
it is down to only one small natural population. Ecuador has an estimated
total of just 80 to 100 birds. Only in Peru, Chile and Argentina's
most precipitous mountains are there pockets of dense populations. |
| As the morning sun grows warmer, more
condors appear from the depths of the Colca Canyon. Today, 18 rise
and fall in circles, never flapping a wing but simply adjusting their
feathers to harness the rising air currents. Dark juveniles dive-bomb
each other in a mock dogfight, while a stately pair of adults cruises
back and forth in synchrony, apparently courting in midair, within
a wingspan of the cliff face. The breeze picks up, and all disappear
high in the sky. Where to? That is part of the mystery. Could these
be the same birds that every year turn up hundreds of miles away along
the desert coast just in time for the sea lion pupping season? |
| During the weeks that follow, we strive
to learn more. We especially want to see where the condors nest. The
native Collagua people, whose ancestors have been cultivating the
canyon for 14 centuries, are friendly and talkative. "Yes, the
condors used to nest in all these crags here above our village, but
not anymore" is a comment we hear again and again. |
| For several days we follow two guides,
Collagua Indian Silverio Cutira Llallachachi and biologist Eduardo
Mejia, in search of condor nest sites. Crag after crag, we come across
perfect condor nesting sites: small deep caves on the faces of vertical
cliffs, each with a guano- splattered perch. Silverio claims to have
seen birds nesting higher than 18,000 feet. We see no condors, but
at one nest in particular, copious whitewash around the cave entrance
attests to frequent traffic. |
| Donning harness and descenders, my climbing
rope looped over a rock outcrop, I slide over the lip of the canyon.
Over my shoulder, mighty crags dwarf patchworks of barley fields.
I ease into the cave's mouth. About 12 feet high at the entrance,
it leads back horizontally about 20 feet to a triangle of flat ground
five feet across that is deeply littered with huge black feathers.
A musky smell hangs in the air-not unpleasant, but more suggestive
of a mammal's lair than a bird's nest. There is no doubt this is a
favored nesting cave used by generations of condors. |
| In captivity, the birds are known to live
50 years or more, and it is likely that they are among the longest
lived of all terrestrial birds. With low natural mortality in the
wild, they need to nest only rarely. When they do, the whole cycle
may require longer than a year. Just to incubate the huge, single
egg takes nearly two months, and after the chick hatches it does not
learn to fly for six months. Even after that, both parents assist
the fledgling for many more months by feeding it and accompanying
it as it acquires condor know-how. |
| Not until age six will a young condor molt
its brown feathers and grow the black-and-white plumage of adults.
Meanwhile it must find its place in condor society and establish a
bond with what will probably be a lifelong mate. If just a few too
many adults die prematurely, the cycle is broken as deaths outstrip
hatchings and population numbers begin to plummet. |
| Walking over a mountain pass, we meet a
smiling old man driving a llama train. "We don't like the condors
much because when they have young to feed they'll swoop right down
on our baby alpacas and kill them," he says. "Some time
ago the people of the nearby village set out a poisoned carcass, killing
25 condors in retaliation in just one day." Other people tell
us, "Condors push full grown cows to their death off cliff edges.
They even carry away live sheep in their talons." |
| Learning about condors from the local residents
is an exercise in separating myth from fact. Any quick look at condor
anatomy, for example, will show that the bird's feet resemble those
of a turkey and therefore are incapable of lifting even a rabbit.
But some of the lore is intriguing, including the assertion that the
condors have their own leader, a very old male the natives refer to
as the "Apu," which in the local tongue means "the
wise one." We are told that no matter how hungry condors might
be, they will not descend on a carcass until the Apu decides it is
safe to do so. |
| Whatever the truth of such tales, it is
true that people long ago hunted wild game down to very low numbers,
and condors are forced to rely on the remains of domestic animals
ranging free in the mountains. Could the intelligent birds really
harass panicked cattle into throwing themselves off a precipice? Or
are the birds simply so clever at finding a carcass soon after the
animal's death that its owner concludes they are the perpetrators? |
| In the Colca Canyon, winter is setting in.
With the thin flush of grass on the high slopes fast shriveling up,
it is time for local people to cull old, unwanted horses and donkeys.
Interested in seeing the condors feed, we construct blinds near a
carcass. |
| We start our vigil crouched between miserably
cold boulders, invisible save for a few tiny peepholes in dense shrubbery.
Within hours after the carcass is deposited, condors gather in ever-growing
numbers, circling high in the sky and perching on rocky ridges. Soon
there are so many condors I can count 28 in my narrow field of view.
Many more swoop low overhead. The eerie sound of the air passing through
wing feathers differs with each bird, from a low treble, to a high
whistle, to one sirenlike whine. |
| One man concerned about the local feeling
about the birds is Mauricio de Romana, who runs a small tourist lodge
in the canyon-and who has founded his own conservation organization,
PRODENA (short for Pro Defensa de la Naturaleza, meaning In Defense
of Nature). Romana has long nurtured a dream: setting aside land for
the first inviolate condor sanctuary. The key, he hopes, will be tourism. |
| About 10 years ago the first visitors started
coming to the Colca Canyon in search of condors; now their annual
numbers have swelled to 30,000. Romana is quick to agree that this
influx needs to be managed. But, he maintains, the new regional industry
could help conservation by pumping money into Peru's troubled economy.
"With tourism taking off, never was there a better justification
to ensure the condor's future," he says. |
| The days pass as we huddle in icy conditions
from before dawn until after dusk, but the condors still don't approach
the carcass. An Andean gray fox makes regular visits to it. A rare
Peruvian huemul doe walks by. One night a chunk of meat is taken from
the carcass, possibly the work of a puma. Still the condors wait,
leaving at the last light of dusk and returning each morning before
the sun rises. |
| Across the Peru-Ecuador border to the north
is a team of very different condor advocates. One, Friedemann Koster,
is a German biologist who settled in Ecuador almost 20 years ago and
became aware of the condor's plight while filming a documentary on
the bird eight years ago. Since then he has teamed up with Fernando
Polanco, a young Ecuadoran whose family owns one of the largest cattle
ranches in the country. The family's own dream is to restore ecological
integrity to much of its land holdings. |
| Together Koster and Polanco have launched
the Condor Huasi Project, meaning "Home of the Condor" in
Quechua. With seven birds rescued from captivity entrusted to them
by the government, their goal is to rekindle the link that once existed
between the species and native cultures. It's a tall order, especially
since condors this century often are considered vermin, and hunting
for the birds often serves as a rite of passage for young men. Using
the captive condors as ambassadors for the species, the project teaches
native children how their ancestors lived close to the great birds
and about the condors' needs. Meanwhile, Polanco's family has agreed
to allay farmers' fears of livestock predation by ensuring a weekly
food supply for the area's wild condors, distributed near the open-air
aviary that holds the captive birds. |
| I watch the huge birds interacting far
in the distance around favorite perches. Two old males engage in mutual
preening. Two others nibble each other's beaks and twine their necks
together, then take turns shoving their heads under one another's
stomach and pushing each other around. Another adult male gives a
subadult rival a spectacular wings- out, head-down, chest-inflated
display. Off to one side a pair is courting, the male's head flushing
brilliant hues of orange and red as he struts and nods around the
attentive female, occasionally cupping his outstretched wings forward
and slowly pivoting in a circle. Then the two fly off together, drawing
figure eights in the sky. |
| Romana, Koster and Polanca are not alone
in trying to aid the Andean condor. In Colombia, biologists are busy
reintroducing young condors hatched in North American zoos to parks
and reserves. In 10 years, 48 have been released, and two years ago
the first repatriated pair successfully raised a wild chick of its
own. (In Venezuela, however, a similar project ended with all the
released birds being shot.) |
| Far to the south, in Argentina, other biologists
are busy turning loose condors equipped with radio transmitters so
their movements in the wild can be tracked. Finding out where the
birds go and how much space each pair needs in different environments
remain among the most critical pieces of information affecting every
rescue effort. And so saving the biggest of Earth's creatures to take
to the sky almost certainly will mean learning more about its many
secrets. |
| On the fifth day, just before sunset, a
stupendous male lands on the slope above the carcass. Head held high,
shoulders squared, feet planted far apart, his entire body language
speaks of dominance. I murmur to Mark, "If the Apu exists, I
think I'm seeing him right now!" |
| For an hour the bird stands stock still.
Then, with daylight fading, the Apu walks deliberately down the slope.
Every condor in sight flops to the ground behind him. As the Apu leads
the charge, some 40 birds march through the tall tussock grass like
an advancing army. They descend on the carcass as one, hissing and
thumping. For the next 20 minutes they feed in a melee of flashing
black-and-white wings, the sounds of tearing hide and snapping cartilage
filling the air. Then, all at once, they take off, flapping heavily
away into the gathering night. |
| I am left with goose bumps prickling my
skin and visions of prehistoric times when great hordes of scavengers
fed on Pleistocene mammals, long before humankind came onto the scene. |
| "Yes, the condors used to nest in all
these crags here above our village, but not anymore." |
| "With tourism taking off, never was
there a better justification to ensure the condor's future." |

Jones traveled to South America four times to report on the Andean
condor. |
