I WAS SITTING IN THE HOLLOW OF A ROCK
carved over thousands of years by the incessant pulse of wind, rain, and wave. The sounds rushed in:
Swissshhh-schwooosh. Tcha-tcha-tcha-tcah. Arerr, arerr, arrer. Chikoo-chikoo.
 Â
It was midmorning; a few hours before, my expedition group had ridden Zodiacs onto the beach at horseshoe-shaped Darwin Bay on Isla Genovesa, one of the northernmost islands in the Galápagos chain. The others in my group had moved on to snorkel off the far tip of the island, but I stayed behind to see how it felt to be the lone soul in that singular place. Â
Well, the lone
human
soul anyway, since I had lots of other company. To my left, dozens of charcoal-brown juvenile red-footed boobies perched among saltbush branches; their parents whirled around the sky. Two black-and-white Nazca boobies waddled past me. Soft-needled cacti sprouted from a cleft in the rock beside me; with no animals to eat them, they've evolved without their protective hard spines. To my right lay a sand-crusted driftwood tree trunk borne from who knows where. Â
The ancestors of some of the wildlife around me had probably arrived on just such a trunk, clinging perilously to the surface of the storm-tossed wood or embedded snugly inside, like passengers on an accidental ark. The volcanic rock around meâpocked with air holes and studded with brown and red stonesâhad been tossed from the earth's fiery crust through a hotspot that sent molten lava spewing onto the seabed in such quantity that it piled up and eventually broke the surface, forming Isla Genovesa, the other almost sixty islands in the chain, and even the hollow in which I sat.  Â
Suddenly, from a thick stand of mangroves I heard a choked squawking, a male red-footed booby trying to attract a mate. Then, straight ahead, oblivious to the human playing castaway among them, three Nazca boobies screeched and squabbled in fierce beak-to-beak combat. Two were ganging up on one, and when the victim rose to confront her tormentors, I saw a light blue egg glistening beneath her. She occupied prime real estate, and the newlyweds wanted it.  Â
A juvenile booby practiced landing to my left, its body wavering to and fro as it fluttered onto a branch. A male frigatebird flew overhead, flashing the red pouch that he puffs into a bright balloon at mating time. Black-and-white swallow-tailed gulls, their eyes outlined in brilliant red, fluttered onto a rocky perch.  Â
At the waterline, black marine iguanas padded across black lava rocks, also dotted with red-and-white Sally Lightfoot crabs. A couple of sea lions fenced with their snouts, bellowing at each other while a whiskery pup flopped along after the bigger one, trying to nurse even while its mother barked at the intruder. Sea lion yelps and roars filled the air and the salt-scented Pacific swashed blue and white.  Â
I swigged water and considered Charles Darwin. Certainly during his seminal visit to the Galápagos aboard the HMS
Beagle
in 1835, the father of evolutionary theory had sailed into the bay now named for him and set foot on this island. But, I thought, it was quite possible that no other human had ever sat precisely where I was. All islands are to some extent worlds apart, but few, as Darwin noted in
The Voyage of the Beagle,
are quite so profoundly separate as the Galápagos. “The natural history of this archipelago is very remarkable,” he wrote. “It seems to be a little world within itself; the greater number of its inhabitants, both vegetable and animal, being found nowhere else.” Â
Sitting in my little corner of that world 600 miles off the coast of Ecuador, I couldn't imagine wanting to be anywhere else. And to think that just a week before I'd been having doubts about this trip. Â
Darwin's voyage from England took four years and was plagued by seasickness; the worst we faced on our two-day trip from San Francisco were airplane meals and in-flight movies. But I contended with one foe that Darwin didn't: long-distance déjà vu. Long before we departed, a film of the Galápagos reeled through my mind. I had already seen countless timesâcomplete with James Earl Jones narrationâboobies, iguanas, frigatebirds, sea lions, giant tortoises, and the rest of the islands' famously fearless birds and beasts. How could reality compete with the digitally enhanced version playing in my head? Â
Also, I am not really a wildlife person. Generally speaking, in my travels I've sought people, art, culture, and cuisine. But with my daughter turning seventeen and my son soon to be thirteen, my wife, Kuniko, and I thought this seemed the chance to put together one final grand family fling before Jenny went off to college and Jeremy eschewed all travel with the folks. And what could be more climactic than the Galápagos? Given all that, I feared that not even Darwin had dragged so much baggage onto the islands. Â
Our voyage began late on a Saturday afternoon. After settling into cabins aboard the
MS Polaris
, meeting our guides, and hearing the first of our daily natural-history lectures, seventy of us passengers and six naturalists piled into
pangas
(motorized Zodiacs) and headed for our first excursion on Isla Santa Cruz.  Â
As we cut through the waves, the warm wind scrubbed away my jet lag and the salt water on my lips awakened my senses. As Jeremy took in his surroundings and spotted a great black frigatebird soaring over us, he wondered aloud at its wingspan. Â
“Up to seven feet,” answered naturalist Paul McFarling. Â
“Wow!” said my son, reaching for his camera.  Â
“You know what it's looking for?” Paul asked.
Jeremy shook his head.
“A booby,” Paul continued. “Frigatebirds are the pirates of the skies. They snatch food from other birds, especially boobies. I've even seen them reach down the neck of a baby booby and take out the fish a mom or dad just fed it.”  Â
Jeremy swallowed hard.  Â
“Look!” Jenny cried, pointing to eight bright yellow leaves the size of platters under the water, their edges gently flapping in the current. When the leaves began to swim, I thought my eyes were playing tricks. Â
“Ah, golden rays,” Paul explained. They soared along with exhilarating ease, undulating in formation like oceanic Blue Angels. Jenny grabbed her camera.
Click, click, click.
 Â
In two hours we motored past a spectacular succession of wildlife: pelicans up there, sea turtles over there, sea lions and sharks, two kinds of iguanas, three kinds of mangroves, hundreds of Sally Lightfoot crabs. Overwhelmed, all we could say was “Look! Look! Look!” as if the world were being reinvented before our eyes. Â
The next morning, after an overnight passage to Isla Espanola, we boarded
pangas
bound for Punta Suarez. As we pulled up to shore, sea lions slid through the waves beside us and bellowed and flopped onto the beach, oblivious to our arrival. Hopping onto black volcanic rock, we realized with a start that all around us were marine iguanas as black as the rock. They sprawled over every available surface, and where no rock was available, they sprawled over each other, sunning themselves, motionless. Â
Momentarily disoriented by the sheer abundance of life on the beach, I failed to see an iguana that was literally underfoot. Â
“Dad, look out!” Jenny shouted.Â
I froze, stopping my boot two inches above the creature's head. It didn't even blink.Â
As I recovered from my near-misstep, Paula Tagle, our naturalist guide for the day, reviewed the rules. “One, don't touch the animals.” (Jenny shot me a grin.) “Two, don't take anythingâ
anything
.” (A glance toward the L.L.Bean-clad septuagenarian holding a seashell.) “Three, don't bring any food onto the islands. And four, stay with your group; don't stray off the trails or beyond the marked areas, and don't wander around on your own.”Â
Jeremy whispered to me, “Do we really have to stay with the group? Can't we just explore on our own?” There was only one answer: When in the Galápagos, you go with the group. So we walked with everyone else, our straggling line rising over boulders and slithering past sere silver-green scrub until we came to a bleak, wind-blasted depression.Â
“We're approaching a prime blue-footed booby nesting spot,” Paula said. A moment later we turned a corner and there they were. At first glanceâat least to my untrained eyesâthey looked like any other gray-and-white birds. But then I spotted my first pair of blue feet. Superb, magnificent, like Dr. Seuss creatures come to life. Blue feet to the left of me, blue feet to the right of me, blue feet in the sky above me and nearly under my feet: “Honey!” my wife, Kuniko, called as I narrowly missed placing a big brown boot on two webbed blue beauties, whose owner looked up at me with curious brown eyes. Â
“Excuse me, your boobiness,” I said with an elaborate bow. Â
Just then, a booby landed to our left with a feathery flourish, splaying its feet out, like Fred Flintstone braking his prehistoric car.Â
“See that display?” Paula asked. “That's the male's way of attracting a mate.”Â
“Guys,” Jenny sighed.Â
Around another bend we witnessed another mating ritual, which I came to think of as the blue-footed booby stomp. Two birds face each other, and one lifts its left foot high in the air, holds it there, and then sets it ceremoniously down. It does the same with its right foot, like a blue-soled sumo wrestler limbering up before a match. Watching them, I realized that there was no comparison between seeing this on the small screen in my living room and actually being here.Â
It only got better, especially for Jenny and me. Having lagged a little behind the others, we were strolling along when, on the path right in front of us, a female lifted herself to reveal a bright white egg.Â
“Dad!” Jenny cried, gripping my arm and pointing. Right then, the shell cracked and a new, wet chick appeared. We watched, stunned, as it struggled into the world and its mother plopped protectively over it. Â
“I've never seen anything like that,” Jenny said.Â
Me neither, I thought. Me neither.Â
I hadn't really associated the Galápagos with underwater life, but as we plunged beneath the waves off Isla La Tortuga, I realized I had omitted an important part of the equation. Black-white-and-yellow Moorish idols with thin arcing top fins, blue-eyed damselfish, and banded butterflyfish swam lazily below us. A pair of sea turtles stroked gracefully by. I finned ahead through a school of brilliant gold-and-blue surgeonfish, which parted to pass me. For a few glorious moments their fins were close enough to tickle my cheeks.Â
I had been hoping for some bonding family moments, and as we poured out our day's stories over dinner that night aboard the ship, I realized that there was something about encountering these extraordinary creatures in their own wild world that cleansed the mind and tugged at the soul.
In the old days, Paula told us, sailors thought the islands were enchanted because they seemed to drift; they were never quite where mariners' maps said they would be. The islands were also working some kind of magic on us, but still, there was the occasional minor mutiny, like when Jenny announced over dessert the next night, “I'm not going to the lecture tonight.”
“Why not?” Kuniko and I asked simultaneously. Not go to the lecture? It was unthinkable.Â
“I'm suffering from an advanced case of I.O.,” Jenny said. Â
“Ai-yo?” I asked, imagining some sort of exotic malady. Â
“I.O.âInformation Overload,” she said, and then wandered off to stargaze on deck. Â
Over the next few days, I too began to experience symptoms of I.O. On every excursion, we had a naturalist assigned to our group, who was invariably a walking encyclopedia, proffering a staggering array of information about whatever serendipity sent our way.  Â
Our morning walk on Isla Genovesa began with the unusual discovery of a frigatebird skull near the path. Picking it up, Paul said, “See the little channels that run down the beak here? They're unique to the frigatebird. It desalinates water through its eyes and the salt runs out down these channels in its beak. Very efficient.  Â
“Oh look!” he continued, pointing to a speck in the sky. “There's a lava gull, the rarest gull in the world. There are only about 800 of them; they're endemic to the Galápagos. Completely gray and they have a very funny laugh. They're little scavengers; I've seen them pick up booby eggs and smash them to get at the food inside.” Â
I was filled with guilt, wonder, and longing. Who knew the world was so rich with factsâbut who could possibly retain them all? Wouldn't it be nice to take a morning off and just sit on the deck in the sun, sipping something cool? But who knew what I'd miss? That would be the day everyone would come back exclaiming about the once-in-a-lifetime (fill in the blank) they'd seen. Â
I tuned back in to Paul's narration. “Ah! Now here we have the large ground finch. You've heard about Darwin's finches and how they were the key to his theory of evolution? On each island the finches developed different characteristics in order to survive. Well, the large ground finch has developed a beak that enables it to crack open and eat enormous seedsâlook at that beak! It could probably crack open a Brazil nut. But the thing is, to have a beak that big and a body so small is very disproportionate, so when it jumps around, it always seems to be pitching forward. Its small body seems to be trying to catch up with its big bill.” Â
