In Borneo, City Pleasures and Jungle Adventure


In Borneo, City Pleasures and Jungle Adventure

A SNOW-WHITE fortress in the style of the English Renaissance, garnished with crenellations, pepper pot turrets and an octagonal keep, is not quite what you’d expect to find on a steamy bluff overlooking an equatorial river in Malaysian Borneo. But Fort Margherita, built in 1879 by Charles Brooke, the second White Rajah of Sarawak, is just one of the many charms of Kuching, a gracious and kaleidoscopically diverse city of about 600,000 just an hour and a half by air from Singapore.
An amble through its safe, eminently walkable streets will reveal dragon-festooned Chinese temples a few blocks from a 19th-century South Indian mosque; fortresses from the time of the White Rajahs (English rulers of the Kingdom of Sarawak from 1841 to 1941) a short walk from a high-rise district of hotels and icily air-conditioned shopping malls; and chic restaurants that would not be out of place in London a few streets away from open-air stalls redolent with half-a-dozen Asian cuisines.
The most extraordinary attractions in the Kuching area, however, are natural. Drive an hour or two out of town and you come to tracts of some of the most ancient and species-rich rain forests on earth. In less than a week, you can plunge into an exotic world of primeval flora and endangered fauna, visit — or live with — a local tribe, and still have time for urban pursuits — i.e. eating and shopping. In addition, many Sarawakians converse comfortably in English, making travel a breeze.
I first discovered the sundry delights of Kuching, which is the capital of the Malaysian state of Sarawak (pronounced sah-RAH-wok) several years ago. My soon-to-be wife, Rachel, was living in Singapore and we decided to escape it for a few days and explore some of Malaysia’s other half. In less than a day I was entranced and decided to return at some point — with a note pad.
When I went with Rachel, we stayed in the center of town, but for this visit I chose a guesthouse a bit off the beaten path. Kuching has several international-standard business hotels, but this place came with a good recommendation, and the fact that the co-owner of the Fairview Guesthouse, Eric Yap, a retired civil servant, offered to show me around was a bonus, especially since many of the places I wanted to go are not accessible by public transport. My game plan was to head to nearby national parks in the morning and explore the city later in the day.
One of my top priorities was to pay another visit to Asia’s only great ape, the orangutan, which is endemic to Borneo and the Indonesian island of Sumatra. Early one morning, after a quick breakfast, Eric and I got into his late-model Honda and drove 20 minutes south from Kuching to the Semenggoh Nature Reserve, whose wildlife center was established 35 years ago to rehabilitate jungle animals rescued from captivity. The 2.5-square-mile area is now one of the best places in the world to see orangutans up close and on the loose.
So far, we were told, 5 of the center’s 27 orangutans — 16 of them born here — have kicked the habit of dining at park headquarters, but the other 22 often swing by (literally) to partake of the banana manna set out each day. We had been forewarned, however, that there was no guarantee that any of the orangutans — the world’s largest tree-dwelling animals — would show up.
“Yaaay-ooh!” the park ranger yelled, the second tone lower than the first, as he scanned the forest canopy, “yaaay-oh!” The energetic rustle of leaves in a distant tree was the first indication that an orangutan was approaching. “If a big male is coming, keep distance. He is unpredictable,” the ranger warned, adding nonchalantly, “he might attack, he might not.” But it was a smallish young ape making his way toward us, clambering from one tree to another, grabbing onto vines and branches with gravity-defying agility.
At one point, we — along with dozens of other visitors — could see five shaggy orangutans clutching trunks, branches and vines with arms that can reach six feet or more. A female orangutan with a baby clinging to the long hairs of her torso descended warily to a stash of bright yellow bananas, stuffed as many as she could in her mouth, grabbed a green coconut in one hand and scrambled up a rope. Soon the last of the climbers disappeared back into the canopy, and Eric and I continued on.
We headed farther south, through a patchwork of dense secondary forests, open fields, houses and small orchards. For tens of millions of years — until logging companies arrived in the late 20th century — Sarawak’s dense rain forests remained unchanged, but today only patches of completely untouched jungle remain.
Our destination was Annah Rais, a Bidayuh village whose residents — or most of them — live in longhouses, a collaborative habitation that serves as a home for the entire community. (The Bidayuh are one of the Bornean indigenous groups known collectively as Dayaks.) In a longhouse, each family retains a high degree of economic autonomy (this is not a kibbutz) but common areas are in constant use for cooking, traditional crafts, socializing and celebrations. If you were making a Dayak version of “Seinfeld,” you’d set it in a longhouse.

Although Bornean longhouses share certain features — all, for example, are built on stilts to insulate them from the damp tropical earth — each Dayak group has its own floor plan and decorative traditions. Among the Bidayuh, communal life is centered on the awah, a roofed, open-air veranda whose width is generally about 12 feet but whose length can exceed that of two football fields. Running along one side of the awah is a wall punctuated by doors to the apartments — or bilik — where individual families live. If you ask how big a longhouse is, chances are you’ll be told how many doors it has.
Annah Rais, whose three longhouses have a total of 97 doors, is one of the best places in the Kuching area to get acquainted with the traditions of the Dayaks. As at virtually all Sarawakian longhouses (especially those accessible by road), modern amenities have been embraced with gusto — locals can’t wait to get broadband Internet — but Annah Rais’s inhabitants have consciously decided both to preserve aspects of their traditional lifestyle and to welcome modern tourists. Several residents run homestays that allow paying guests the opportunity to meet local people, dine on Bidayuh cuisine (and help prepare it), drink home-brewed rice wine and try (mock) hunting with a blowgun. For day visits, after paying a nominal fee to the longhouse committee, visitors are free to explore the village, either on their own or with a guide.
The floors of Annah Rais’s public spaces are made of bouncy bamboo slats, which added a spring to our steps as Eric and I took a stroll. We soon came upon an older woman named Bawe who was cutting rattan into long, even strips in order to weave a mat. Her 47-year-old cousin, a traditional drummer named Pola Anak Nan, was seated nearby and we soon struck up a conversation in English. The mat is “for her own use,” he explained, adding that the Dayak mats available for sale in Kuching, many imported from Kalimantan (the Indonesian part of Borneo), are of “poor quality — people in the village don’t touch it.” Our parents, he added, smiling, “they very choosy.”
Our next stop was the head house, a legacy of the Bidayuhs’ days as fearsome headhunters. True to its name, the structure’s centerpiece was a cage containing about a dozen human skulls, blackened by smoke and suspended above an old brass cannon marked “Pieter Seest Anno 756.” (Pieter Seest was a bell and gun founder active in Amsterdam in the 1700s.) These days, almost all Dayaks are Christian (mainly Anglican, in the case of Annah Rais), and the heads are no longer believed to protect the village.
Back in Kuching, I took time to explore the city the way it should be, on foot and aimlessly. For a first-time visitor, most of the highlights — temples, mosques, Chinatown, several excellent museums, and restaurants — are within a short walk of Kuching’s Waterfront Promenade, a half-mile-long ribbon of flower beds, tropical trees and food stalls that is especially refreshing whenever a cooling breeze blows off the Sarawak River. Couples and families flock here in the early evening, when the hues of an equatorial sunset are gradually outshone by strings of colored fairy lights and their watery reflections.
The road that runs along most of the waterfront has long been known as Main Bazaar. These days, its arcaded, colonial-era Chinese shophouses shelter Borneo’s best selection of traditional Dayak artifacts, handmade by members of the Iban, Bidayuh and Orang Ulu (upriver) groups. This is the place to come if you’re looking for any sort of native tools and crafts, along with hand-woven textiles and sachets of Sarawak’s famously piquant pepper. Browsers are welcome and, in most shops, staff members are happy to explain each item’s origin and its traditional significance and functions.

Kuching’s increasingly sophisticated culinary scene reflects the city’s multicultural population, which is about 38 percent Chinese, 36 percent Malay and 24 percent Dayak (mainly Bidayuh and Iban). Over the course of my stay, I ate deliciously crunchy stir-fried midin (jungle fern tips), fiery Sarawak-style laksa (noodle soup), Teochew-style Chinese kueh chap (fish and prawn soup) flavored with crunchy-hot slivers of ginger, and delicious pepper steak at an elegant French-inspired restaurant. There are also several Indian restaurants and, for the spice-averse, KFC.
Another culinary highlight is the Weekend Market, half a mile from the town center on Satok Street, which runs from midday on Saturday until Sunday afternoon. Open-air stalls, many run by Bidayuh farmers from the interior, sell brightly colored local crops — winged beans, okra, ginger, bright red chilies — on tiny plates for a ringgit or two (33 or 66 cents). At a table piled high with bananas ranging from lemon yellow to dark red — some barely larger than my thumb, others almost the length and girth of my forearm — I got into a conversation (in English) with the owner, who gave me nine varieties to taste. Despite my protests, he refused payment and — not for the first or last time — I found myself astonished at Sarawakians’ generosity.
“A RAFFLESIA is flowering!”
It was with this exclamation that Eric’s wife greeted me one afternoon as I was pondering my next move. Because this bulletin — the local equivalent of a hot tip for the afternoon horse race — was both unexpected and time-sensitive, it made the decision easy.
Texas-size Borneo is home to some of the most extraordinary plants on earth and one of the rarest is the elusive Rafflesia, the world’s largest flower, some of whose species can produce blooms over three feet in diameter. Because Rafflesia flowers last for just a few days before rotting, we quickly made plans to leave the next morning.
After a 44-mile, two-hour drive northwestward, we arrived at Sarawak’s best place for Rafflesia spotting, Gunung Gading National Park, a 16-square-mile patch of old-growth rain forest overlooking the South China Sea.
The Rafflesia (pronounced rah-FLEE-zhuh) plant is a rootless, stemless, leafless parasite that consists almost entirely of the flower. It attaches itself to vines of the Tetrastigma plant, a member of the grape family, from which the Rafflesia’s filament-like tentacles suck prodigious quantities of nutrients. The genus Rafflesia is named after Sir Stamford Raffles, who discovered the flower for Western science while leading an expedition to the Sumatran rain forest in 1818. (He is better remembered for what he did the following year: founded Singapore.)
A few hundred yards into the forest, our guide turned off the plank walk and we followed him across a rocky hillside. Suddenly, there it was, nestled at the base of two moss-flecked boulders: an orange-red Rafflesia tuan-mudae 30 inches in diameter, its five meaty petals mottled with warty raised spots. The basketball-size diaphragm in the center, speckled with white spots on the inside, enclosed a disk resembling a spiky lotus flower.
The flower’s reproductive organs — each Rafflesia is either female or male — are hidden under the disk, but beyond that scientists understand little about how the flower, whose buds take nine months to mature, manages to reproduce. They do know, however, why Rafflesias smell like rotten meat: to attract carrion flies for pollination. I bent down and put my nose practically inside the flower’s core. Though the odor was hardly overpowering, you wouldn’t want to eat a chicken cutlet that had smelled like a Rafflesia before it was cooked.
As I neared the end of my stay, there was still something I had yet to see: a wild troupe of one of Borneo’s most endangered — and oddest — primates, the proboscis monkey. It was in search of this peculiar creature, endemic to Borneo, that I spent my final evening in Sarawak cruising through Kuching Wetlands National Park, whose pristine mangrove forests are accessible only by boat (easy enough to arrange through your guesthouse or hotel).


In the company of an Italian couple from Turin, Eric and I drove 15 miles north to the seaside village of Kampung Santubong and boarded an open motorboat. Along the shore — the tide was very low — mangrove roots poked out of the mud like thousands of fat, knobby pencils stuck in vertically, eraser-first.
Our affable guide and boatman, Sarbini bin Labong, slowed the outboard to a purr, pointing toward the shore at what he said was a monkey. All I saw were swaying branches. Then I heard the crashing of tree limbs and caught sight of a flash of reddish-brown fur — a potbellied proboscis monkey jumping from one tree to the next in search of choice young leaves. Grunts and chirps emerged from what we soon realized was a troupe of about 10 of the agile creatures. True to their name, the adult males cast an unmistakable profile thanks to their pendulous noses.
When darkness had fully fallen, we began hunting for Sarawak’s most feared creature, the man-eating saltwater crocodile, which can grow to a length of 20 feet or more (it is considered to be the world’s largest living reptile). We chugged into a narrow channel and Sarbini again cut the motor, rowing as he shined a flashlight toward the muddy shore. Little splashes emerged from the blackness as unseen fish broke the surface.
Suddenly we saw a gleam — reptilian eyes reflecting the boatman’s beam. Silently, we approached and spotted a snout and two greedy eyes just above the water line. As we drew near, the critter moved and, for the first time, we could make out its true dimensions. It was a baby — no more than two feet long; he (or she) would have been able to drown and devour a Barbie doll but that’s about it. Without stretching the truth (as long as we were vague on the details), we could now report to the folks back home that we had encountered a hungry crocodile in the wild and lived to tell the tale.
As we headed back to the main channel we slid past ink-black trees silhouetted against an almost black sky. Fireflies swirled around one particular tree, and for a fleeting moment, gasps of “bellissimo!” turned our boat into a tropical gondola. Then Sarbini revved the motor and we zoomed toward the twinkling lights of Santubong — and the creature comforts of Kuching.

Hamlet (and Others) as the Strong, Silent Type


Hamlet (and Others) as the Strong, Silent Type

WASHINGTON — For their first attempt at wordless Shakespeare — that’s right, wordless Shakespeare — the husband-and-wife leaders of the Synetic Theater company chose to apply their physical-theater aesthetic to “Hamlet,” counting on audiences’ familiarity with the plot.

In place of three-plus hours of verse, Synetic presented 90 minutes of highly stylized dance, movement, acrobatics, pantomime, music and story. “To be or not to be” was never uttered, but Hamlet stormed across the stage, gesturing to convey desperation. He and Ophelia never touched; their tortured attraction was reflected, instead, by the two actors’ bringing “their fingertips to within a hair’s breadth of each other,” as TheWashington Post noted in its rave review in 2002.
Just a year-old troupe at the time, Synetic ended up drawing wide critical praise and winning local theater awards as best resident play for “Hamlet” and best director and best choreographer for the husband-and-wife team, Paata and Irina Tsikurishvili, who also played Hamlet and Ophelia. Since then Synetic has won many more local awards — mostly for wordless Shakespeare stagings like “Macbeth” and “Romeo and Juliet” — as well as a devoted following in this city and nationally among admirers of physical theater.
Émigrés from the former Soviet republic of Georgia whose style draws on the popular tradition of pantomime there, the Tsikurishvilis (pronounced T-SEE-koorish-VEAL-ee) have also been embraced by establishment theaters here.
“No one does what they do — not in Washington or, really, anywhere that I know of,” saidMichael M. Kaiser, president of the John F. Kennedy Center for the Performing Arts, who has advised the couple on building a theatrical troupe and provided performance space for some Synetic productions.
What he likes about Synetic’s artistry, Mr. Kaiser said, is that “it starts from a theatrical base — what plot and characters do we want to portray? — and then creating the most imaginative physical movements in service to that story.”
During a long interview over tea here, the Tsikurishvilis described yearning for a wider audience to discover their large-scale works of physical theater. “I think if any place other than Washington would appreciate what we do, it would be New York,” Mr. Tsikurishvili said. “But we wanted to spend the last 10 years developing into a premier physical theater company, and that took all our energy.”
With a budget of $1.7 million this year, Synetic produces four to five mainstage plays and three shows for children and families each year. Most performances this season are at the Lansburgh Theater in downtown Washington or at the company’s theater in Arlington, Va., where an encore presentation of Synetic’s text-free “Midsummer Night’s Dream” is to begin on Tuesday.
Last fall Synetic was among 10 theater companies nationwide to receive the first set of $10,000 grants to support their work from the American Theater Wing, a nonprofit group that is a presenter of the Tony Awards. Before 2010 that grant money went to New York companies, but Howard Sherman, the Wing’s executive director, said it wanted to honor innovative companies with rising profiles in their cities and towns and with distinctive artistic vision that stood out nationally.
“Synetic impressed us for their singular, idiosyncratic, exuberant physical style, which clearly wasn’t like others on the Washington scene, and for the obvious embrace in which they were held by their growing audiences,” Mr. Sherman said.
Ms. Tsikurishvili, a sinewy dancer in her late 30s with the expressive face of a silent-movie star, said she knew that Synetic was onto something special with physical theater during her first performance of Ophelia’s suicide, as she ran across the stage gathering flowers and then “folding and unfolding and dissolving my body as Ophelia drowned.”
“You get this feeling inside you, and then the feeling is pushing your body, as if movement and speech are coming out of your body rather than out of your mouth,” Ms. Tsikurishvili said. “After we were done, and the curtain came down, there was a silence that was going on for a century. And then people started clapping.”
Both raised in the capital city of Tblisi, the Tsikurishvilis met in the late 1980s at the Georgian State Pantomime Theater, where they had worked in separate productions. Mr. Tsikurishvili had trained in pantomime and acting and had broken free of his parents’ expectations that he become a scientist or scholar. Irina, meanwhile, gravitated to dance after an early interest in ballet faded because she could not perform on pointe (despite her father’s sitting on her knees to strengthen them).
One day in a hallway of the theater, Ms. Tsikurishvili recalled, she slid through a pack of actors and dancers — Mr. Tsikurishvili and his friends — and ended up teasing him with a possible invitation to a swimming outing the next day. (She finally offered, and he went.) It was not love at first sight, Irina said; she did not fall for him until she saw him onstage.
“He was playing a chicken, in this Georgian family-oriented play about a fox, and I finally understood how an actor can use his face and body to full effect, how a character’s story could be told without words,” she said. They married four months after their first meeting.
Mr. Tsikurishvili, now 44, was known in Tblisi theater circles then as an outspoken critic of the government and the deprivations of daily life; in time he stopped getting much work. He ended up defecting during a performance tour in Germany and worked there for several years while Ms. Tsikurishvili raised their young son, Vato, in Georgia. (They now have a daughter, Anna, as well). Eventually they both came to Washington, where Ms. Tsikurishvili’s parents settled after her father was offered a job teaching and coaching gymnastics.
At first Mr. Tsikurishvili performed as a mime for patrons at Russian restaurants in the region, while Ms. Tsikurishvili taught gymnastics in Baltimore. They began acting with the Stanislavsky Theater Studio in Washington, but broke away after a few years to start Synetic — a name that Mr. Tsikurishvili coined by fusing syllables of two words, synthesis and kinetic, that he thought captured their aesthetic.
While some Synetic productions include full texts and speaking, like a recent adaptation of Bulgakov’s novel “The Master and Margarita,” the production next week of “Midsummer” particularly captures their signature style: un-self-consciousness, bravado and an undeniable sexiness, including a highly erotic wrestling match between Ms. Tsikurishvili’s fairy queen Titania and her sparring partner, King Oberon. (In March Synetic will take on “King Lear.”)
With the company now in its 10th year, the Tsikurishvilis are eager to take Synetic on the road, especially to New York, where they have performed only once — last year atColumbia University during a benefit for its Georgian Studies program.
“Our great wish since we were children was to perform in New York City and on Broadway,” Mr. Tsikurishvili said. As much as he looks forward to performing more beyond Washington someday, Mr. Tsikurishvili said that the physical theater of Synetic also brings him back, in his imagination, to Georgia and to the couple’s early days together.
“You miss home sometimes, we both do, but physical theater involves living in an imaginary world, the world of a children’s mind like my own in the ’70s,” he said. “I had no toys. I amused myself with what I could make my body do. When we perform, still, I think of where we’re from as well as where I hope we go.”

For Many Species, No Escape as Temperature Rises

KINANGOP, Kenya — Simon Joakim Kiiru remembers a time not long ago when familiar birdsongs filled the air here and life was correlated with bird sightings. His lush, well-tended homestead is in the highlands next to the Aberdare National Park, one of the premier birding destinations in the world.

When the hornbill arrived, Mr. Kiiru recalled, the rains were near, meaning that it was time to plant. When a buzzard showed a man his chest, it meant a visitor was imminent. When an owl called at night, it foretold a death.
“There used to be myths because these are our giants,” said Mr. Kiiru, 58. “But so many today are gone.”
Over the past two decades, an increasing number of settlers who have moved here to farm have impinged on bird habitats and reduced bird populations by cutting down forests and turning grasslands into fields. Now the early effects of global warming and other climate changes have helped send the populations of many local mountain species into a steep downward spiral, from which many experts say they will never recover.
Over the next 100 years, many scientists predict, 20 percent to 30 percent of species could be lost if the temperature rises 3.6 degrees to 5.4 degrees Fahrenheit. If the most extreme warming predictions are realized, the loss could be over 50 percent, according to the United Nationsclimate change panel.
Polar bears have become the icons of this climate threat. But scientists say that tens of thousands of smaller species that live in the tropics or on or near mountaintops are equally, if not more, vulnerable. These species, in habitats from the high plateaus of Africa to the jungles of Australia to the Sierra Nevada in the United States, are already experiencing climate pressures, and will be the bulk of the animals that disappear.
In response to warming, animals classically move to cooler ground, relocating either higher up in altitude or farther toward the poles. But in the tropics, animals have to move hundreds of miles north or south to find a different niche. Mountain species face even starker limitations: As they climb upward they find themselves competing for less and less space on the conical peaks, where they run into uninhabitable rocks or a lack of their usual foods — or have nowhere farther to go.
“It’s a really simple story that at some point you can’t go further north or higher up, so there’s no doubt that species will go extinct,” said Walter Jetz, professor of ecology and evolutionary biology at Yale, whose research last year predicted that a third of the 1,000 mountain birds he studied, or 300 species, would be threatened because warming temperatures would decimate their habitats.
Birds are good barometers of biodiversity because amateur birdwatchers keep such extensive records of their sightings. But other animals are similarly affected.
Two years ago, scientists blamed a warming climate for the disappearance of the white lemuroid possum, a niche mountain dweller in Australia that prefers cool weather, and that was cute enough to be the object of nature tours. Many scientists, suspecting that the furry animal had died off during a period of unusually extreme heat, labeled the disappearance the first climate-related animal extinction.
Since then, biologists have found a few surviving animals, but the species remains “intensely vulnerable,” said William F. Laurance, distinguished research professor at James Cook University in Australia, who said that in the future heat waves would probably be the “death knell” for a number of cold-adapted species.
For countries and communities, the issue means more than just the loss of pleasing variety. Mr. Kiiru regrets the vastly diminished populations of the mythic birds of Kikuyu tribal culture, like buzzards, owls and hawks. But also, the loss of bird species means that some plants have no way to pollinate and die off, too. And that means it is hard for Mr. Kiiru to tend bees, his major source of income.
Current methods for identifying and protecting threatened species — like the so-called red list criteria of the International Union for Conservation of Nature, a conservation gold standard — do not yet adequately factor in the impact of probable climate shifts, and the science is still evolving, many scientists say.
Some species that scientists say are at most risk in a warming climate are already considered threatened or endangered, like the Sharpe’s longclaw and the Aberdare cisticolain Kenya. The cisticola, which lives only at altitudes above 7,500 feet, is considered endangered by the international union, and research predicts that climate change will reduce its already depleted habitat by a further 80 percent by 2100.
Other Kenyan birds that are at risk from climate warming, like the tufted, brightly coloredHartlaub’s turaco, are not yet on watch lists, even though their numbers are severely reduced here. A rapid change of climate can quickly eliminate species that inhabit a narrow niche.
On a recent afternoon, Dominic Kimani, a research ornithologist at the National Museums of Kenya, combed a pasture on the Kinangop Plateau for 20 minutes before finding a single longclaw. “These used to be everywhere when I was growing up,” he said.
He added: “But it’s hard to get anyone to pay attention; they are just little brown birds. I know they’re important for grazing animals because they keep the grasses short. But it’s not dramatic, like you’re losing an elephant.”
As the climate shifts, mountain animals on all continents will face similar problems. Scientists at the University of California at Berkeley recently documented that in Yosemite National Park, where there is a century-old animal survey for comparison, half the mountain species had moved their habitats up by an average of 550 yards to find cooler ground.
Elsewhere in the United States, the pika, the alpine chipmunk and the San Bernardino flying squirrel have all been moving upslope in a pattern tightly linked to rising temperatures. They are now considered at serious risk of disappearing, said Shaye Wolf, climate science director of the Center for Biological Diversity in San Francisco, which in 2010 applied to protect a number of American mountain species under the United States’ Endangered Species Act.
Last year, new research in the journal Ecological Applications and elsewhere showed that the pika, a thick-furred, rabbitlike animal that takes refuge from the sun in piles of stones, was moving upslope at about 160 yards a decade and that in the past decade it had experienced a fivefold rise in local extinctions, the term used when a local population forever disappears.
On the Kinangop Plateau in Kenya, Mr. Kimani exults when he finds a Hartlaub’s turaco, once a common sight, near Njabini town, in a stand of remaining of old growth forest, after engaging local teenagers to help locate the bird. The turaco could lose more than 60 percent of its already limited habitat if current predictions about global warming are accurate, Dr. Jetz said.
“Even substantial movement wouldn’t help them out,” he said. “They would have to move to the Alps or Asian mountains to find their mountain climate niche in the future.”

An earlier version of a photo caption with this article misidentified a bird that was pictured. It is a Tacazze sunbird, not a sandbird.
