Some hikers moved
as effortlessly as strollers on a city street. Dave Johnson studied the woods
and the rocks along the path with something like admiration. Minturn Wright,
the Academy of Natural Sciences chairman, and Rod Thompson, the coal-mine
owner, moved slowly and steadily onward while almost everyone else rested. They
looked like a lawyer and his client walking to an important appointment in the
business district, their calm features showing none of the ravage and strain
evident on almost everyone else's faces. W. E. Saunders, a well-known
ornithologist, has written that you could measure the loss of your hearing
ornithologically. At the age of 60 he found he could no longer hear the notes
of the golden-crowned kinglet. At 65 he could no longer hear the song of the
cedar waxwing. At 68 he could not hear the Cape May warbler. Saunders
understated the cost of bird watching. By mid-afternoon I could not even see
any birds. In fact, I could hardly see the trees. In a way Allison had an
advantage over the rest of us. Never having been camping before, she thought
all outdoor recreation Was like this. Bird-watching stops were now
perfunctory—the pretext that they were to look at birds was dropped. They were
to rest. I noticed that instead of scanning the trees, Allison was staring
straight upward at heaven. Later she told me that she had once read a newspaper
account of a helicopter that landed in the yard of a Mexican prison and plucked
out an important convict; she was hoping it might come back and rescue her.
I was reduced to
walking 200 steps and stopping, counting slowly to 100 before walking another
200. By four in the afternoon I was walking 100 steps and counting to 200. Soon
I was down to 50 steps and repeating the Lord's Prayer. Somewhere along about
here I began to have hallucinations. I thought I was the last climber in the
line, but suddenly there was somebody behind me. An Englishman, tall and
extremely pale, materialized on the trail and lifted my pack off my back.
"Let me help you with this," he said. It was not an Englishman, it was
George Plimpton. He walked on ahead, staggering a little from the weight of my
pack and that of the mysterious Harrison. My first reaction was one of deep
gratitude, followed by an impulse to ask him if he would carry me, too. I met
him again, half a mile on. He was sitting beside the trail with the two packs
beside him, looking exhausted. I picked up my own and went on. He seemed
pleased.
About seven
o'clock we tumbled and slid into the broad clearing at the summit. Camp was
made in darkness on the banks of a small stream, a quarter of a mile from the
settlement. "We will get up at five o'clock," said Victor, "and
start out as a group as soon as it is light. Then we will separate into small
groups to cover as much territory as we can, in the hope that somebody will
hear the guan calling, and we can concentrate in that area."
The cloud forest
is inanimate. The cloud is a filmy, gossamer vapor rather than a fog; it drips
down unevenly, like a sagging tent, sometimes only an arm's reach overhead,
more often entangled in the lower branches of the trees. There is nothing to
compare it with. Sometimes it suggests film sets for German expressionist
movies like The Cabinet of Dr. Caligari, or those old scary illustrations of
Hansel and Gretel lost in the woods, but mostly it seems displaced, rolling
slowly and billowing gently among the motionless trees. Looking down from a
ridge in the sunlight, the cloud is a milky, wavelike expanse of piles of
vapor, through which dark branches project like those of trees partly submerged
in a flood.
The call of the
horned guan is a low, vibrant, mooing sound that seems to radiate in all
directions; it is almost impossible to determine where it is coming from or
from what distance. "You don't hear it," Victor said. "You feel it.
It is the heartbeat of the cloud forest." Every ornithologist who has
studied the call has remarked on its ventriloquial character. Blake said,
"Few sounds in nature are more difficult to trace...the most unpredictable
bird I have ever hunted." Authorities are uncertain about the call itself,
sometimes describing it as a soft, distant lowing, or as a resonant dovelike
sound, or as a low, mooing booming. The amateur bird watchers among us were
more imaginative; they said it was like a cow mooing and snoring at the same
time, or like a foghorn muffled by distance, or like the bass strings of a
giant harp.
On the first day
it was heard only once, faint and untraceable. On the second day it was not
heard at all. If it really was the heartbeat of the cloud forest, the forest
was dead; there were no vital signs. We were now divided into small groups,
straining our ears over wider expanses. Victor and the experts carried a
parabolic microphone, borrowed from the Cornell Laboratory of Ornithology, to
record the call of the guan in the wild. Victor also carried a large tape
recorder with an amplifier and a battery of tapes of the calls of
birds—quetzals, trogons, even the horned guan.
We split up into
small groups so that we could cover more territory and enhance our chances of
spotting a guan. Our group of four was assigned to the trails that ran down the
Pacific slope from El Triunfo. Except in the early morning, before the sun
burned off the cloud, there was little chance of finding a horned guan in that
direction. This may have been just as well. Neither Tom and Mary Ann, nor
Allison and I, were skilled enough to add any scientific information about the
bird if we saw it. There was, however, a chance that we might see the second
great rarity of El Triunfo. Back in 1866 Dr. Jean Cabinis, editor of the
Journal f�r Ornithologie in Berlin, reported a new species of tanager in
Central America. It was a small green-and-blue bird, the upper back a light
metallic green, the lower back and rump a soft, washed blue. This was the
azure-rumped tanager, tangara cabanisi, and a specimen was given to the Berlin
Museum. Two years later P. L. Sclater, secretary to the Zoological Society of
London, received another specimen, shot at Costa Cuca near the border of
Guatemala and Mexico. These two stuffed birds were the only proof that the
tanager really existed. "Extremely rare," says Peterson and Chalif's A
Field Guide to Mexican Birds. In 1937 an azure-rumped tanager was collected on
Mount Ovando in Guatemala not far south of El Triunfo. Two more were collected
in Chiapas in 1943.
We did not find
it. But rounding a bend in the trail, coming out of the thickets, we did see
the Pacific beyond a wide expanse of headland. On this side of El Triunfo the
mountain dropped almost straight down; an ancient trail, even steeper than that
from the coffee plantation, threaded around ridges and spurs. Along this trail
in 1972 an expedition saw three azure-rumped tanagers and the species has been
observed several times since. We saw other treasures—a black-throated jay, a
brown-backed solitaire, a spotted nightingale-thrush—but we failed to see a
trace of the tanager. It was not possible to spend much time looking for it, or
for anything. While going down the steep trail was easy, our problem lay in
getting back up to camp before dark.
By the end of the
third day Victor appeared to be growing a little desperate, even though the
guan had been seen once. Bill Failing, a former Army counterintelligence
officer, spotted it as it flew across the trail, but it was merely glimpsed,
and it produced no sound.
Bird-watching
books assert that the great advantage of the sport, or pastime, or hobby, or
whatever it is, lies in that it can be practiced anywhere. Start in your own
backyard. "It is not necessary to walk vast distances," says A Guide to
Bird Watching. Wide varieties can be found in "cultivated fields, farm
buildings, orchards, ungrazed wood lots, stream borders, springs, cattail
swamps, sedge marshes, conifer groves, sandy fields, cliffs, bogs, golf
courses, airports, cemeteries and so on."
