The Burning Man of Birding: Inside Iceland’s Puffin Festival

For decades Icelanders have celebrated the Atlantic Puffin even while they've served it up on plates. But some traditions can't last forever.

Let鈥檚 just get this out of the way: No, it does not taste like chicken. Soaked in salt water, smoked with wood chips and dried sheep dung, then boiled for two hours in a sweet malt beverage before being refrigerated and finally served, bone-in and cold, alongside a packet of butter, smoked puffin tastes briny and a bit fishy and musky-sweet in the manner of mesquite barbecue. In life, an Atlantic Puffin stands just 10 inches tall, its wings stubby and narrow; when its tiny torso is served in a paper tray, it鈥檚 difficult even to recognize as having belonged to a bird. It looks vaguely insectoid, its wings all but meatless, thin bones curving out like antennae. The breast meat is a deep mahogany and pulls apart fibrous-but-tender, like the flesh of a medium-ripe peach.

The venue that sells this ostensible delicacy is a center-pole big top tent erected in a long-extinct volcanic crater on Heimaey, the largest island in , or the Westman Islands, seven miles off Iceland鈥檚 southern coast. The crater valley is on the outskirts of the Westmans鈥 only town鈥攊tself called Vestmannaeyjar, population 4,400ish鈥攁nd is surrounded by steep, green cliffs. On their seaward-facing slopes, hidden in the short grass and soft volcanic soil, are some 100,000 puffin burrows, a fraction of the 1.1 million burrows found in more than 20 colonies scattered across the Westmans鈥 18 islands. From May until September, about 20 percent of the world鈥檚 Atlantic Puffins鈥攕ome 830,000 nesting pairs鈥攂reed on the archipelago, along with similarly impressive numbers of murres, guillemots, fulmars, gannets, Razorbills, and kittiwakes.

But the puffin in my tray didn鈥檛 come from the Westmans. It was harvested 225 miles away, off Iceland鈥檚 northern coast, then imported to Vestmannaeyjar to be smoked and eaten during a  called, in its anglicized form, Thjodhatid (pronounced thoth-ha-TEETH). The word literally means 鈥減eople鈥檚 feast,鈥 and for most of its history, that feast鈥檚 main dish has been smoked puffin, served alongside pastries, lamb, flatcakes, and other  delectables in some 300 white tents that locals erect in the valley each year. This tent city is Thjodhatid鈥檚 base camp, and as recently as a decade ago you couldn鈥檛 poke your head into a stranger鈥檚 tent (which is encouraged) without being handed a plate of smoked puffin and a strong drink to wash it down.

Charred and Feathered

These days, though, the only place to reliably find smoked puffin at Thjodhatid is in the concession tent, where, alongside cheeseburgers and chicken fingers, it鈥檚 sold for 1,500 krona, or about $12, per bird. That鈥檚 three times what it cost 20 years ago, making one little puffin an expensive snack; it鈥檇 take three birds to make a modest meal. So it isn鈥檛 a popular menu item鈥攖he concession tent has stocked just 600 birds for a three-day fest that regularly draws 16,000 people. Still, the puffin has its devotees.

鈥淚 ate it twice yesterday,鈥 declares Anna Kristin Sigurdardottir, the concession employee who rings me up. 鈥淎nd I鈥檒l eat it again tomorrow. I look forward to it all year.鈥

鈥淧eople here used to eat it year-round,鈥 adds Kristina Goremykina, Sigurdardottir鈥檚 coworker. But that was before it got expensive, back when Westman islanders still hunted puffins, before they started noticing alarmingly fewer young birds. Now that it鈥檚 imported from up north, smoked puffin is only a special treat.

So what happened? Goremykina tosses a butter packet into a puffin tray and shrugs. 鈥淭hey all flew away or something,鈥 she says.

The Westman Islands鈥 puffins haven鈥檛 flown away; they鈥檝e stopped breeding successfully. Since 2003 Atlantic Puffin colonies here have experienced what Erpur Snaer Hansen, director of ecological research for the Vestmannaeyjar-based , characterizes as 鈥渂reeding failure, basically.鈥 For more than a decade, chick production in the Westmans has been virtually nil, with fewer adults breeding and only a scatter of chicks surviving to fledge (most of them dangerously thin). The result is a puffin population that鈥檚 gradually aging away: Precious few puffins arriving in the Westmans each year are younger than 10 years old. While puffins can live (and breed) for more than 30 years, their average lifespan is about 16. Already the islands have seen breeding pairs drop by as much as 15 percent since the late 1990s.

I arrive at Hansen鈥檚 home in Vestmannaeyjar the day before Thjodhatid, in late July. It鈥檚 toward the end of Hansen鈥檚 field season, a time when the 49-year-old biologist likes to blow off steam. His family hosts a tent at the festival each year (though they don鈥檛 eat puffin), and in the Thjodhatid spirit of hospitality and excess, Hansen begins plying me with drink within minutes of welcoming me.

Over 20-year-old port, I hear about the 鈥減uffin rally,鈥 a cross-country road trip Hansen takes each summer, monitoring puffin burrows at 12 different colonies across Iceland. In June he and his colleagues inspect at least 40 burrows at each site, snaking a camera down the winding, four- to-six-foot tunnels to check whether each is occupied and, if so, whether its occupants have an egg. Hansen鈥檚 team uses an infrared camera mounted to what鈥檚 basically a drain snake鈥攁 custom-made device inspired by a plumber friend鈥檚 invention.

In July Hansen and company return to each colony to see whether the eggs have hatched, to assess chicks鈥 health, and to photograph adults carrying 鈥渇ood loads.鈥 Under normal circumstances, puffins with new chicks head to sea several times a day, returning to the burrow with cargoes of small fish. It鈥檚 the classic postcard puffin shot: a close-up of that mime-white face, that melancholy eye, that splashy lobster-claw of a beak, with limp fish ends dangling out both sides like a silver mustache.

In southern and western Iceland, those dangling ends have historically belonged to sand eels, a cylindrical fish generally known to Americans as sand lances. In the Westmans, Hansen says, their relationship to puffins is 鈥渓ike the hare and the lynx鈥濃攁 primary prey to the near-exclusion of any other species. And for 12 years, on the heels of gradually climbing sea surface temperatures, sand eels have gone missing from surrounding waters.

Well, not missing exactly, Hansen says, now pouring us tumblers of a peaty Scotch. Sand eel numbers have surged in Iceland鈥檚 northern waters, where puffin populations once similarly relied on cold-loving capelin. The capelin, too, have shifted northward鈥攂ut puffin populations in northern Iceland are stable, feeding on the sand eels that have flourished in the capelin鈥檚 wake.

Around the Westmans, however, no suitable prey has thrived in the sand eels鈥 place. And while adolescent puffins might shop around for an alternate breeding ground, once adults have chosen a colony, they鈥檙e hardwired to return to it. In other words, the Westmans鈥 breeding-age puffins can鈥檛 just up and move to better fishing grounds, and it鈥檚 a rare day when the puffin-rally photographer captures a returning adult with much of anything in its beak.

Icelanders love festivals, and considering the country has just 329,000 residents (dramatically outnumbered by 7 million to 8 million Atlantic Puffins), they sure seem to throw a lot of them. A handful of high-profile music and art fairs go down the same weekend as Thjodhatid. In November, Reykjavik鈥檚 famed Iceland Airwaves fest has long attracted music industry VIPs. Of late, the Icelandic version of the international All Tomorrow鈥檚 Parties festival has been one of hipsterdom鈥檚 hottest tickets.

Thjodhatid dwarfs them all. It , when storms kept Westman islanders from attending a mainland celebration of the millennial anniversary of Icelandic settlement. So the islanders threw their own party, which has since evolved into a gonzo celebration of Icelandic and Westmans culture, with three distinct phases.

During the day, Thjodhatid is a family funfair, with ziplines and puppet shows for kids. Come evening鈥攚hich lasts from roughly 7 p.m. until midnight, since there are 18 hours of daylight here in midsummer鈥攖he adults join in, wining and dining in the white tents and gathering in the steep natural amphitheater for Icelandic pop bands and fervent sing-alongs to folk songs and patriotic anthems. Then, at midnight each night, comes a different grand spectacle: an enormous bonfire on Friday, four stories of wooden pallets throwing heat across the whole valley; fireworks on Saturday that thunder off the crater walls; and on Sunday, following a climactic sing-along, a ceremony with 141 flares arranged around the crater鈥檚 rim and simultaneously lit, creating a gargantuan ring of fire. Midnight at Thjodhatid makes the Super Bowl halftime show look like a kiddie party with sparklers.

Overnight, the carousing intensifies, with more drinking and singing and feasting in the come-one-come-all tents. Many celebrants are costumed, so you might find yourself in the small hours toasting a caped superhero or being serenaded by men in bunny suits. Other revelers wear PVC fishing bibs鈥攁 salute to Vestmannaeyjar鈥檚 maritime culture but also practical protective wear should you lose your footing on the steep, muddy slopes of the concert area.

Insofar as it celebrates the Westmans鈥 culture, Thjodhatid also celebrates seabirds. At the festival鈥檚 entrance hangs a huge banner with a giant puffin wearing a crown of fire. The opening ceremony involves an elegant demonstration of spranga, a locally beloved sport of rope-swinging and rappelling that鈥檚 rooted in the practice of collecting seabirds鈥 eggs from cliffside colonies. Each year鈥檚 Thjodhatid gets its own theme song, several of which lyrically invoke puffins and other birds. One I hear emanating from several tents is (or 鈥淚n the Slopes鈥), which jauntily declares: 鈥淲ith romance and smoked puffins, I set off to meet my friends!鈥

And so back to those smoked puffins. Historically, puffin hunting in the Westmans has meant standing at the edge of a cliff, swinging a long-handled net called a hafur to catch birds as they flit about. This method overwhelmingly captures non-breeding adolescents, since breeding puffins tend not to flit, instead flying directly in and out of burrows as they deliver and seek food. With a hafur net, a single hunter could once easily bag several hundred puffins a day. Hunters kept a few dozen, then gave the rest to the local hunting club, which sold the birds鈥攖o tourist restaurants in Reykjavik, say, or to families for Thjodhatid鈥攁nd used the proceeds to maintain stately hunting lodges on the Westmans鈥 wild islands.

It was hunters who, in the early 2000s, first noticed a dramatic decline in young puffins and petitioned the local government to recruit a specialist. Hansen鈥檚 position was funded in response in 2007. He started by photographing birds, aging them by their bills and realizing that several years鈥 worth of adolescents were essentially missing from the population. Hansen earned the hunters鈥 ire when he subsequently called for a puffin-hunting ban. 鈥淭hey were a little angry with me,鈥 he says. 鈥淪ome didn鈥檛 believe what we were saying. It was really tough.鈥

But spooked by their empty nets, hunters soon came around. Today puffin hunting in the Westmans is allowed on just three days in August鈥攁nd catches are so low that few hunters even bother.

For Hansen, one benefit of the Westmans鈥 hunting legacy is the harvest record, which dates to 1880. Since the catch has always consisted chiefly of adolescents, harvest numbers are a reliable proxy for chick production. Plot them alongside sea surface temperature records and inferred trends in sand eel abundance, and a pattern emerges: Puffin chick production is strongest during cool phases of a natural oceanic temperature cycle called the Atlantic multidecadal oscillation (AMO). But during the AMO鈥檚 warm phases, sand eel abundance withers and chick production suffers. Hansen suspects that warm winters speed up the sand eels鈥 metabolisms, so that the weakened fish don鈥檛 survive to become next summer鈥檚 prey. Higher ocean temps might also disturb sand eels鈥 planktonic food chain, and they face competition and predation from mackerel that frequent southern Iceland鈥檚 waters during warm periods.

A full AMO cycle is roughly 20 to 40 years of cool followed by 20 to 40 years of warm. The current warm phase began in the mid-1990s, and some predict the AMO could shift back to cool as early as the mid-2020s鈥攗nless climate change intervenes.

Hansen is among many scientists concerned that a linear warming trend may be overtaking the cyclical AMO. 鈥淚f you look at the temperature record for the North Atlantic,鈥 says Morten Frederiksen of Denmark鈥檚 Aarhus University, who studies seabird adaptations to marine habitat changes, 鈥渁t least for the last 30 or 40 years, you鈥檒l see an upward trend that is not explained by those cycles.鈥

What鈥檚 more, says Tycho Anker-Nilssen of the Norwegian Institute for Nature Research, substantial breeding failure is also occurring in the Faroe Islands and Norway鈥檚 Rost archipelago, which together host another 15 percent or so of the Atlantic鈥檚 puffins, and where populations rely on prey other than sand eels. Since warming sea surface temperatures are the common denominator, says Anker-Nilssen, 鈥渋t is likely that larger-scale climate variability and change is the key driver.鈥

So what if climate change warms the North Atlantic to the point where even cool AMO phases are still too warm for sand eels to thrive in the Westmans? 鈥淭hat鈥檚 exactly what we鈥檙e super worried about,鈥 Hansen says. 鈥淭hat it鈥檚 going to level off, and that means we鈥檝e seen a shift northwards. And this place is done.鈥

Puffins are inescapable around downtown Vestmannaeyjar. Everywhere you look, the bird appears like a totem: on murals, on road signs, wearing a bamboo hat and advertising Chinese takeout. Puffin bric-a-brac shops abound, as do fliers for puffin tours.

Vestmannaeyjar even has its own puffin celebrity in Toti, a charismatic rescue bird who draws visitors to the island鈥檚 natural history museum. Famous enough to warrant his own segment on Icelandair鈥檚 in-flight tourism video, Toti was brought in four years ago after fledging too late to join the migration to open-sea wintering grounds. It鈥檚 a late-summer tradition in Vestmannaeyjar for children to roam the streets, gathering fledglings that emerge disoriented from burrows and head for the lights of town. Toti鈥檚 caretaker, Viktoria Pettypiece, is among those who measure and weigh the wayward chicks (collecting data for Hansen) before releasing them to the sea. Twenty years ago, she says, kids would bring in 1,200 to 2,000 puffins a year. In recent years it鈥檚 often dipped below 100.

Pettypiece, who once ran a gallery selling puffin paraphernalia, wonders how the breeding collapse might affect the island鈥檚 image. 鈥淚 think it鈥檇 be really hard for tourism,鈥 she says. 鈥淢ost people who come here come to see puffins鈥攅ven if it鈥檚 the wrong time of year.鈥

鈥淚 believe it might affect the number of visitors a bit,鈥 agrees Indiana Audunsdottir, co-owner of a popular waterfront restaurant called Slippurinn, 鈥渆specially if we keep pushing the idea about puffins as part of the islands鈥 identity.鈥 Slippurinn has earned accolades for its commitment to local sourcing and traditional Icelandic fare鈥攂ut the restaurant doesn鈥檛 serve smoked puffin.

鈥淚t鈥檚 sad, but traditions have to end when traditions have to end,鈥 says Audunsdottir. Of course, she adds, stocking a restaurant with puffins is different than simply hunting or buying a few to take home. She laughs sheepishly. 鈥淚 tried some the other day, and I was like, mmm! So I am a complete hypocrite.鈥

A few blocks away, in the chic dining room at the Hotel Vestmannaeyjar, the special Thjodhatid menu does indeed feature plates of smoked, thinly sliced puffin. 鈥淟ike carpaccio,鈥 says hotel owner Magnus Bragason. 鈥淛ust to give a taste.鈥

Until he bought the hotel four years ago, Bragason was the Westmans鈥 go-to puffin smoker, but he was proud when hunters effectively gave up their hafur nets, since the prospect of wholesale population collapse has him spooked. 鈥淚 think it would be very bad for our culture,鈥 he says. 鈥淚鈥檓 very happy that we are not killing them, and I鈥檓 not sure if we鈥檒l start again.鈥

Still, Bragason misses the tradition, and his family is among those who bought some imported puffins to eat at home during Thjodhatid. Last year, before his son went on a student exchange to Maine, his host family asked over Skype about his favorite food. 鈥淪moked puffin!鈥 declared Bragason鈥檚 son, without hesitation.

鈥 鈥極h, my god!鈥 鈥 Bragason laughs, remembering the host family鈥檚 chagrin. It was hard for them to understand, he says. 鈥淧eople here love puffins, even if we eat them.鈥

A hazily remembered (thankfully recorded) 3 a.m. scene from Thjodhatid: I鈥檝e just emerged from a particularly boisterous tent, decorated inside with homemade (ironic?) Donald Trump campaign signs. A 鈥淭rump 2016鈥 button is pinned to my vest. Inside, I was fed beer and pastries and made to pose with a cardboard cutout of the Donald. I鈥檓 relieved to have escaped.

Outside, a retired fisherman named Grimur Juliusson is telling me in spotty English how, with the Westmans hunt curtailed, imported puffins are too expensive to serve in the tents. I ask him: Are islanders saddened by the puffins鈥 breeding collapse?

鈥淛a,鈥 he nods, 鈥渂ecause the puffins is part of the island. He is our . . .鈥 Juliusson hunts for words, then says slowly, 鈥淭he puffins is the same as you and me.鈥

I am touched by this sentiment. Then an eavesdropping neighbor chimes in. This puffin situation has happened before, he insists 鈥 we鈥檒l all be eating smoked puffin again soon. 鈥淣ature,鈥 he admonishes, 鈥渋s a cycle. Nature is not like a straight line.鈥

It鈥檚 a common view around the Westmans, but Hansen is less confident. The day after the festival, around dusk, he leads me to one of his monitoring sites, a busy puffin colony on a rounded, windswept peninsula. Westman islanders have a saying when they鈥檙e feeling run-down鈥斺淚 feel like it鈥檚 the Monday after Thjodhatid鈥濃攁nd Hansen and I are prime specimens. Whether it鈥檚 the hangover or the stirring sight of a thousand puffins dotting the cliffs, Hansen is reflective. I recount the exchange outside the Trump tent.

鈥淭hey鈥檙e saying this because they believe it鈥檚 going to come back,鈥 he says, 鈥渂ut they have no clue if that鈥檚 going to happen. Nobody does. It鈥檚 wishful thinking.鈥

We watch a pair of puffins 鈥渂illing鈥濃攔ubbing their absurd beaks together in courtship. Puffins are silent above ground, and the only sounds we hear are the crying of gulls and the crashing of waves.

The twilight of puffin hunting and eating in the Westmans is a small victory for conservation. Islanders are doing what they can in the face of a warming ocean: preserving potential breeders and hoping for the best. But what鈥檚 poignant about a Thjodhatid without smoked puffin is the reminder it provides that climate change doesn鈥檛 affect only the natural world鈥攐r, say, where we build our houses. It鈥檚 going to mess with our identities. It鈥檚 going to change the meals we share and the songs we sing.

The puffins of the Westmans won鈥檛 disappear soon and may never vanish completely. Even in the worst-case climate scenario, today鈥檚 mature birds will keep returning without much breeding success, and island visitors will see what Hansen calls 鈥渟hadows of the past.鈥 But today鈥檚 immense colonies may indeed dissolve, and if they do, they鈥檒l take some of the freewheeling, open-armed Thjodhatid spirit along with them.

When Hansen and I leave the colony, it is every bit as dusky as when we arrived. In Iceland, the sun sets very slowly.
