VALLE DEL CAUCA, Colombia — From the side of an old highway that cuts through the Andean foothills, Dora Alicia Londoño’s home looks unremarkable. Located in a rural area about two hours from Cali, the largest city in southern Colombia, it’s a simple, two-story concrete building with a sheet metal roof. A few potted plants hang from the rafters.  The main attraction is in her backyard.  There, you will find birds. So many birds. And these are not just your common backyard varieties, like robins and bluejays, but rare forest species that birdwatchers around the world yearn to see. Londoño, 63, has turned her home into a birdwatching lodge, a paradise. There are five guest rooms and a cafe with a view into her backyard, a dense tropical forest. There, she has a homemade bird feeder: wooden shelves holding pieces of fruit. Upstairs, on the roof, she had additional feeders for hummingbirds. When I visited on a warm morning in October, it felt like stepping into a nature documentary. The backyard was teeming with birds, none of which I’d seen before: glistening green mountain tanagers, toucan barbets, lemon-browed flycatchers, velvet-purple coronets. These birds were so colorful they almost looked unreal, painting the yard with streaks of yellows, reds, blues, and purples. And then there was the noise — a clamor of cheeps, trills, and squawks.   “The toucan barbet is one of the rarest birds in the world and it just eats bananas right here,” said Natalia Ocampo-Peñuela, a Colombian-born conservation ecologist and bird expert at the University of California Santa Cruz, who was at Londoño’s with me that morning. In an hour or so, I saw about 45 different species, Ocampo-Peñuela estimates, while leisurely sipping coffee and eating empanadas. If this is birdwatching, I’m in. If you’re into birds, Colombia is the place to be. It has more avian species than any other country on Earth, with close to 2,000 distinct and often very beautiful varieties, nearly 20 percent of the world’s birds. That diversity is rooted in geography. Colombia is a mosaic of different habitats, from tropical rainforest to snow-capped mountains, and different birds have adapted to each of them. And as I experienced that morning, birding here can be incredibly easy. You don’t even need hiking shoes. !function(){"use strict";window.addEventListener("message",(function(a){if(void 0!==a.data["datawrapper-height"]){var e=document.querySelectorAll("iframe");for(var t in a.data["datawrapper-height"])for(var r=0;r<e.length;r++)if(e[r].contentWindow===a.source){var i=a.data["datawrapper-height"][t]+"px";e[r].style.height=i}}}))}(); This isn’t much of a secret. In the last decade, the activity of birdwatching has exploded in Colombia, said Ocampo-Peñuela, who also studies ecotourism. Activity on eBird, a platform where birders can record their observations, increased more than 27-fold in Colombia since 2010, according to unpublished research by Ocampo-Peñuela and other authors that’s currently under review. While the bulk of these birders are foreigners from places like the US and Canada, more and more Colombians are picking up the hobby, too, she said.  This burgeoning industry is, as many experts argue, a rare force of good. It’s funneling money into rural communities and creating material value for healthy forests — something the environmental movement has, for decades, struggled to do. Indeed, at a time when tropical forests and grasslands are besieged by farming, mining, and other threats, birdwatching tourism offers a real incentive to keep ecosystems intact. Without forests, there are no birds, no birders, and no birding tourism.  There are, no doubt, concerns about sustainability as this young industry matures and more foreign tourists descend on Colombia. But for now, local communities are at the helm of this industry, which is good for people, good for the local economy, and good for wildlife. They intend to keep it that way. Londoño, who goes by Doña Dora, didn’t dream of running a birdwatching lodge and welcoming tourists into her backyard. In the 1990s, she moved here, to the outskirts of Cali, to escape violence near her home in the tropical grasslands, known as Los Llanos. This story is not uncommon. A decades-long conflict between armed groups and the government has displaced more than 5 million people across the country.  Doña Dora arrived with nothing, she told me that morning, as we watched hummingbirds flutter around a pair of freshly filled feeders like a collection of airborne jewels. She cleaned homes and sold empanadas on the side of the road. Her husband picked up odd jobs. Then one day she went to the dentist, and her life changed.  Her dentist, a man named Gilberto Collazos Bolaños, was a bird fanatic, and he knew the forest around her home was full of avian life. So he gave her a suggestion: Put some fruit on a table outside, and wait. The fruit will draw in birds, she remembers him saying, the birds will attract tourists, and the tourists will bring in money. She took his advice. And birds came. First there were bluebirds, golden tanagers, and colorful finches called euphonias. Then rarer species like rufous-throated tanagers and toucan barbets arrived. Toucan barbets are the unequivocal stars of the show. Found only in the mountain forests of western Colombia and Ecuador, they have a brilliant plumage — a collection of light gray, red, yellow, and black — and a song that sounds a bit like a frog. As the dentist predicted, birders eventually arrived, too, largely finding her home by word of mouth. And in 2015, Colombia hosted its first annual BirdFair, a major birding festival, and one of the event’s official field trips was a visit to Doña Dora’s home. That put her on the map, she told me.  “We always loved nature and trees,” said Doña Dora, who, when I visited, was wearing a head covering and what looked like a white lab coat. “But we didn’t have a vision for what we have right now, of birdwatching.” Today, her home is considered one of the country’s top birdwatching destinations, and some visitors have dubbed it “the best backyard birding spot in the world.” It’s this birding business that now supports her family.  Foreign tourists pay about $9 to view birds on her property ($13 if they have a camera). A room for two people is around $50 per night, which doesn’t include her coffee or her homemade empanadas. In the busy season, from September to March, the lodge will get more than 100 tourists a month, according to her son Elber Sanchez Londoño, who helps run the business. In her backyard that morning, I watched birds. But I also watched birdwatchers watch birds. I honestly found this activity just as thrilling.  What is it that makes some people so obsessed with birds? One explanation is that you can find them pretty much everywhere. That makes birdwatching easy to start and practice, no matter where you live. Birding can also connect you to a community. It tends to bring like-minded people together, both in person and through platforms like eBird and iNaturalist, where they can share their observations. Plus, it’s free and done outdoors, which is one reason why birding became so popular during the Covid-19 pandemic when people were avoiding crowded, indoor spaces. “It’s like an addiction,” Ocampo-Peñuela, a self-identified birder, told me. “You see these birds, and their beauty, and it just fills you with happy hormones. Then you want to do it more.” That morning, I met several tourists at Doña Dora’s lodge. Most of them toted cameras with long lenses. “This is unbelievable,” said Santiago Ferro, a visitor from Toronto, who grew up in Bogotá. I asked him how this spot compares to birding in North America. He just laughed. Birders are drawn to Colombia for its sheer number of avian species, many of which are found nowhere else. But the ongoing surge in birding tourism has far more to do with safety. Until recently, a conflict between the government and a number of armed groups spread violence across Colombia. At the center of the conflict — which began in the mid-20th century — was the distribution of wealth. The largest such group, Fuerzas Armadas Revolucionarias de Colombia (FARC), fought against the government and right-wing paramilitary groups to bring more wealth to poor rural parts of Colombia. Violence tied to the conflict killed more than 200,000 people, and most of them were civilians. In 2016, after years of tense negotiations, the government and FARC signed a peace agreement. Put simply, the agreement required that FARC give up their weapons, stop fighting, and exit the drug trade, which was helping fund the conflict. In return they were offered political power and a promise to invest heavily in rural areas.  Violence still persists in some regions, especially near the borders, and the US State Department advises people to reconsider traveling to Colombia. Yet a tenuous truce holds. The peace agreement has made the country much safer, for locals and foreigners alike, than it has been for decades — and that, in turn, has opened the door to more birdwatching tourism.  In 2017, Ocampo-Peñuela published a study showing that birdwatching, as measured by activity on eBird, was already expanding in areas that were once considered dangerous, including Putumayo, a department in southern Colombia. Ocampo-Peñuela’s more recent research, which is not yet published, finds that birdwatching activity skyrocketed in Colombia after 2016, though it dipped during the pandemic. (A large portion of eBird users are from the US, so data from the platform over-represents American birding trends.) !function(){"use strict";window.addEventListener("message",(function(a){if(void 0!==a.data["datawrapper-height"]){var e=document.querySelectorAll("iframe");for(var t in a.data["datawrapper-height"])for(var r=0;r&lt;e.length;r++)if(e[r].contentWindow===a.source){var i=a.data["datawrapper-height"][t]+"px";e[r].style.height=i}}}))}(); The government doesn’t track birdwatching activity, though it says tourism overall is climbing. Last year, a record 6.1 million foreigners visited Colombia, up 30 percent from 2022, and the majority of them are looking for nature experiences, according to Procolombia, a government agency that markets the country. Tourism is already up this year compared to 2023, Procolombia told Vox. And since 2021, the number of nature lodges, including birding lodges, has nearly tripled, the agency said.  In global hot spots of biodiversity like Colombia, economic growth often comes at the expense of ecosystems. A growing cattle-ranching industry destroys rainforests. A mining boom leaches toxins into streams and soil. Comparatively, Colombia’s ballooning birdwatching industry seems like something to celebrate.  Tourism is not only funding birdwatching destinations like Doña Dora’s but building demand for local birdwatching guides. That’s created jobs for Colombians with deep ties to their surrounding ecosystems, whether or not they have a formal education. Generational knowledge of local birds and where to find them — referred to in some academic circles as traditional ecological knowledge — is increasingly valuable here, even in a straight economic sense. Birdwatching tourism gives it value. The following morning, I traveled to a place called Laguna de Sonso, a wetland just north of Cali. It’s a blip of natural habitat in a sea of sugarcane plantations, a widespread crop in Valle del Cauca. When I arrived, a cocoi heron, a large gray and white bird with a long, sharp beak, was wading in the water, sending ripples out across a lake. The wetland is a birder’s dream. More than 300 avian species live in or pass through Laguna de Sonso, including giants like the osprey and weirdos like the common potoo, a bird with an unsettlingly wide mouth. It’s also where youth from the surrounding communities learn to become birdwatching guides, or interpreters, as they call themselves. “We call ourselves interpreters because we are a community that has had empirical training,” said local guide Jhonathan Estiven Bedoya Betancourth, meaning they’ve learned through observation and experience. “We do not have, let's say, the training of a professional tourist guide.” (A pair of community organizations at Laguna de Sonso do offer workshops and mentorship for bird guiding.) Bedoya Betancourth, 24, says he’s been guiding birdwatching tours since he was 14. “We interpret everything that this beautiful territory has,” said Bedoya Betancourth, who wore a pair of binoculars around his neck.   Bedoya Betancourth started guiding because he loves birds, and he’s good at it. He can imitate the calls of around 30 species, he said. (I obviously asked him to demonstrate, and he impressively whistled the repetitive up-and-down call of a marsh bird called the gray-cowled wood-rail.) But it was also a way to earn money for his family, he said. He makes about $35 for each guiding trip, not including tip, and he’ll lead several trips a month. He supplements his income by making wood carvings to sell to tourists and locals.  “Birdwatching for me and for the group of interpreters is one of the economic activities that has been able to keep the community afloat,” said Maria Omaira Rendon Rayo, a community leader at Laguna de Sonso.  The birding economy gives people a reason to stay in the community, she said, and offers an alternative to careers that might attract violence, such as cultivating and selling drugs. By training kids, the laguna and its community organizations are also helping build a conservation ethic that will last for decades. “If you are receiving economic income from an activity such as conservation, then you want to conserve more,” said Rendon Rayo, who works with a local organization called Asociación de Productores Agropecuarios del Porvenir, which helps restore forests by planting trees and trains birding guides in Laguna de Sonso. “You want to help plant more trees. You want to help keep the laguna clean.” Nature tourism is not an unequivocal force of good. It actually often harms the environment, as researchers like Ralf Buckley have documented. Tourists have inadvertently introduced invasive species to places like the Galapagos Islands, snorkelers and divers have damaged coral, including in the Great Barrier Reef, and hotels are commonly built atop natural habitat. There’s also an exploitation issue: In many cases tourism companies are owned by foreigners, limiting the benefits that flow to local communities, on which they often depend. Plus, as a place swells with wealthy tourists, the cost of necessities like housing and food can rise, making it unlivable for locals.  Birdwatching tourism in Colombia has so far managed to avoid many of these pitfalls. It has some guardrails built in, Ocampo-Peñuela said. For one, birding doesn’t work well in large groups — they scare away birds and make it hard to spot something fluttering far away — and smaller groups have a lighter environmental impact. One of the lodges I visited capped the number of tourists to 10. Another said there are days when they will turn visitors away. What’s more is that finding rare and endemic species, which birders are most drawn to, typically requires local expertise. That helps keep money within local communities.  Then there’s the most important guardrail: Birdwatching tourism doesn’t work if it’s not sustainable. Even if you put out fruit, the birds won’t come if they have no habitat — no forest, no wetland. Birding is not like going to the zoo, where you can always expect to see animals. It’s in the economic interest of the birdwatching industry to make sure ecosystems remain healthy.  “You can’t do this business without conserving,” Javier Rubio, who runs another birdwatching destination, called La Florida, at his property northwest of Cali. “If you don't conserve, you put your future as a business at risk. If you start cutting down trees and damaging the forest, [the birds] will be left without food, which is the reason why they are here.” Doña Dora says one of her goals is to earn enough money so that her son can buy forested land around their home. He wants to conserve it, she told me. “That’s the idea for the future,” Elber, her son, told me, “to make sure that the birds continue to live in a healthy ecosystem.” The industry is still young, so the full extent of its environmental impact has yet to be seen. People involved in growing birdwatching tourism say it’s critical that Colombians, and especially people in rural, bird-filled regions, determine what the industry ultimately looks like. “It’s necessary that we Colombians define what kind of birdwatching tourism we want,” said Carlos Mario Wagner, the founder and director of Colombia BirdFair and one of the country’s most well-known birders.  Birding tourism shouldn’t just cater to foreigners, he said, but also to locals. “Something that makes me very happy is that Colombians are increasingly hiring guides,” Wagner told me. Birding has given Colombians an opportunity to reconnect with their homeland following the peace agreement, he said. It instills in them a sense of pride for a version of Colombia that’s known for nature, not violence. The birding industry will ultimately never be huge, Ocampo-Peñuela says. While it’s growing globally — faster than other forms of ecotourism, she’s found — it will likely remain niche, limited by the small number of people who want to travel to rural places to look at birds, often very early in the morning. “You have to have the right personality,” she told me.  So it’s not like birdwatching alone will fix Colombia’s problems and raise the rural class out of poverty.  Yet what it offers is incredibly special. Not just money for local communities, alternative career paths, and real incentives to save forests, but also something that’s harder to quantify. On a rainy afternoon in October, I visited Rubio at La Florida. Like Doña Dora, Rubio has a homemade bird feeder in his yard constructed with branches and pieces of fruit. It attracted a different cast of avian visitors. Here, the star was the multicolored tanager, a colorful species found only in the mountain forests of Colombia. My favorite, however, was the crimson-rumped toucanet, which is essentially a mini toucan. They’re bright green with rust-colored beaks that seem far too big for their bodies.  Over my fourth cup of black coffee, Rubio told me he was a criminal lawyer for nearly three decades before getting into the birdwatching business. A few years ago, he invited friends to his home to go birding. They saw the multicolored tanager and told him that his property — which abuts a tropical forest — has enormous potential to become a birdwatching destination.  Eager to live a more relaxing life, Rubio, 56, quit his job as a lawyer and started building a tourism business.  “I feel extremely good doing this,” Rubio told me. “I often feel like I’m giving happiness to people. Almost unanimously the people who come say, ‘This is a paradise.’ When you start birdwatching, you start to feel attracted not only to birds but to the peaceful environment of nature.” This is a point that nearly every birder I spoke to made: Caring about birds is a gateway to caring about nature, of seeing its true worth.  “It is a gradual process,” Rubio told me, as we sat on a covered deck as it rained, watching a multicolored tanager bounce around in the branches a few feet away. “You first contemplate them, then you begin to understand them, and then you begin to preserve them. That is the path taken by the one who takes up this habit of birdwatching.”

VALLE DEL CAUCA, Colombia — From the side of an old highway that cuts through the Andean foothills, Dora Alicia Londoño’s home looks unremarkable. Located in a rural area about two hours from Cali, the largest city in southern Colombia, it’s a simple, two-story concrete building with a sheet metal roof.

He supplements his income by making wood carvings to sell to tourists and locals. 

“Birdwatching for me and for the group of interpreters is one of the economic activities that has been able to keep the community afloat,” said Maria Omaira Rendon Rayo, a community leader at Laguna de Sonso. 

The birding economy gives people a reason to stay in the community, she said, and offers an alternative to careers that might attract violence, such as cultivating and selling drugs. By training kids, the laguna and its community organizations are also helping build a conservation ethic that will last for decades.

“If you are receiving economic income from an activity such as conservation, then you want to conserve more,” said Rendon Rayo, who works with a local organization called Asociación de Productores Agropecuarios del Porvenir, which helps restore forests by planting trees and trains birding guides in Laguna de Sonso. “You want to help plant more trees. You want to help keep the laguna clean.”

Nature tourism is not an unequivocal force of good. It actually often harms the environment, as researchers like Ralf Buckley have documented. Tourists have inadvertently introduced invasive species to places like the Galapagos Islands, snorkelers and divers have damaged coral, including in the Great Barrier Reef, and hotels are commonly built atop natural habitat. There’s also an exploitation issue: In many cases tourism companies are owned by foreigners, limiting the benefits that flow to local communities, on which they often depend. Plus, as a place swells with wealthy tourists, the cost of necessities like housing and food can rise, making it unlivable for locals. 

Birdwatching tourism in Colombia has so far managed to avoid many of these pitfalls. It has some guardrails built in, Ocampo-Peñuela said. For one, birding doesn’t work well in large groups — they scare away birds and make it hard to spot something fluttering far away — and smaller groups have a lighter environmental impact. One of the lodges I visited capped the number of tourists to 10. Another said there are days when they will turn visitors away.

What’s more is that finding rare and endemic species, which birders are most drawn to, typically requires local expertise. That helps keep money within local communities. 

Then there’s the most important guardrail: Birdwatching tourism doesn’t work if it’s not sustainable. Even if you put out fruit, the birds won’t come if they have no habitat — no forest, no wetland. Birding is not like going to the zoo, where you can always expect to see animals. It’s in the economic interest of the birdwatching industry to make sure ecosystems remain healthy. 

“You can’t do this business without conserving,” Javier Rubio, who runs another birdwatching destination, called La Florida, at his property northwest of Cali. “If you don't conserve, you put your future as a business at risk. If you start cutting down trees and damaging the forest, [the birds] will be left without food, which is the reason why they are here.”

Doña Dora says one of her goals is to earn enough money so that her son can buy forested land around their home. He wants to conserve it, she told me. “That’s the idea for the future,” Elber, her son, told me, “to make sure that the birds continue to live in a healthy ecosystem.”

The industry is still young, so the full extent of its environmental impact has yet to be seen. People involved in growing birdwatching tourism say it’s critical that Colombians, and especially people in rural, bird-filled regions, determine what the industry ultimately looks like. “It’s necessary that we Colombians define what kind of birdwatching tourism we want,” said Carlos Mario Wagner, the founder and director of Colombia BirdFair and one of the country’s most well-known birders. 

Birding tourism shouldn’t just cater to foreigners, he said, but also to locals. “Something that makes me very happy is that Colombians are increasingly hiring guides,” Wagner told me. Birding has given Colombians an opportunity to reconnect with their homeland following the peace agreement, he said. It instills in them a sense of pride for a version of Colombia that’s known for nature, not violence.

The birding industry will ultimately never be huge, Ocampo-Peñuela says. While it’s growing globally — faster than other forms of ecotourism, she’s found — it will likely remain niche, limited by the small number of people who want to travel to rural places to look at birds, often very early in the morning. “You have to have the right personality,” she told me. 

So it’s not like birdwatching alone will fix Colombia’s problems and raise the rural class out of poverty. 

Yet what it offers is incredibly special. Not just money for local communities, alternative career paths, and real incentives to save forests, but also something that’s harder to quantify.

On a rainy afternoon in October, I visited Rubio at La Florida. Like Doña Dora, Rubio has a homemade bird feeder in his yard constructed with branches and pieces of fruit. It attracted a different cast of avian visitors. Here, the star was the multicolored tanager, a colorful species found only in the mountain forests of Colombia. My favorite, however, was the crimson-rumped toucanet, which is essentially a mini toucan. They’re bright green with rust-colored beaks that seem far too big for their bodies. 

Over my fourth cup of black coffee, Rubio told me he was a criminal lawyer for nearly three decades before getting into the birdwatching business. A few years ago, he invited friends to his home to go birding. They saw the multicolored tanager and told him that his property — which abuts a tropical forest — has enormous potential to become a birdwatching destination. 

Eager to live a more relaxing life, Rubio, 56, quit his job as a lawyer and started building a tourism business. 

“I feel extremely good doing this,” Rubio told me. “I often feel like I’m giving happiness to people. Almost unanimously the people who come say, ‘This is a paradise.’ When you start birdwatching, you start to feel attracted not only to birds but to the peaceful environment of nature.”

This is a point that nearly every birder I spoke to made: Caring about birds is a gateway to caring about nature, of seeing its true worth. 

“It is a gradual process,” Rubio told me, as we sat on a covered deck as it rained, watching a multicolored tanager bounce around in the branches a few feet away. “You first contemplate them, then you begin to understand them, and then you begin to preserve them. That is the path taken by the one who takes up this habit of birdwatching.”

Giant Sloths and Many Other Massive Creatures Were Once Common on Our Planet. With Environmental Changes, Such Giants Could Thrive Again

If large creatures like elephants, giraffes and bison are allowed to thrive, they could alter habitats that allow for the rise of other giants

Giant Sloths and Many Other Massive Creatures Were Once Common on Our Planet. With Environmental Changes, Such Giants Could Thrive Again If large creatures like elephants, giraffes and bison are allowed to thrive, they could alter habitats that allow for the rise of other giants Riley Black - Science Correspondent July 11, 2025 8:00 a.m. Ancient sloths lived in trees, on mountains, in deserts, in boreal forests and on open savannas. Some grew as large as elephants. Illustration by Diego Barletta The largest sloth of all time was the size of an elephant. Known to paleontologists as Eremotherium, the shaggy giant shuffled across the woodlands of the ancient Americas between 60,000 and five million years ago. Paleontologists have spent decades hotly debating why such magnificent beasts went extinct, the emerging picture involving a one-two punch of increasing human influence on the landscape and a warmer interglacial climate that began to change the world’s ecosystems. But even less understood is how our planet came to host entire communities of such immense animals during the Pleistocene. Now, a new study on the success of the sloths helps to reveal how the world of Ice Age giants came to be, and hints that an Earth brimming with enormous animals could come again. Florida Museum of Natural History paleontologist Rachel Narducci and colleagues tracked how sloths came to be such widespread and essential parts of the Pleistocene Americas and published their findings in Science this May. The researchers found that climate shifts that underwrote the spread of grasslands allowed big sloths to arise, the shaggy mammals then altering those habitats to maintain open spaces best suited to big bodies capable of moving long distances. The interactions between the animals and environment show how giants attained their massive size, and how strange it is that now our planet has fewer big animals than would otherwise be here. Earth still boasts some impressively big species. In fact, the largest animal of all time is alive right now and only evolved relatively recently. The earliest blue whale fossils date to about 1.5 million years ago, and, at 98 feet long and more than 200 tons, the whale is larger than any mammoth or dinosaur. Our planet has always boasted a greater array of small species than large ones, even during prehistoric ages thought of as synonymous with megafauna. Nevertheless, Earth’s ecosystems are still in a megafaunal lull that began at the close of the Ice Age. “I often say we are living on a downsized planet Earth,” says University of Maine paleoecologist Jacquelyn Gill.Consider what North America was like during the Pleistocene, between 11,000 years and two million ago. The landmass used to host multiple forms of mammoths, mastodons, giant ground sloths, enormous armadillos, multiple species of sabercat, huge bison, dire wolves and many more large creatures that formed ancient ecosystems unlike anything on our planet today. In addition, many familiar species such as jaguars, black bears, coyotes, white-tailed deer and golden eagles also thrived. Elsewhere in the world lived terror birds taller than an adult human, wombats the size of cars, woolly rhinos, a variety of elephants with unusual tusks and other creatures. Ecosystems capable of supporting such giants have been the norm rather than the exception for tens of millions of years. Giant sloths were among the greatest success stories among the giant-size menagerie. The herbivores evolved on South America when it was still an island continent, only moving into Central and North America as prehistoric Panama connected the landmasses about 2.7 million years ago. Some were small, like living two- and three-toed sloths, while others embodied a range of sizes all the way up to elephant-sized giants like Eremotherium and the “giant beast” Megatherium. An Eremotherium skeleton at the Houston Museum of Natural Science demonstrates just how large the creature grew. James Nielsen / Houston Chronicle via Getty Images The earliest sloths originated on South America about 35 million years ago. They were already big. Narducci and colleagues estimate that the common ancestor of all sloths was between about 150 and 770 pounds—or similar to the range of sizes seen among black bears today—and they walked on the ground. “I was surprised and thrilled” to find that sloths started off large, Narducci says, as ancestral forms of major mammal groups are often small, nocturnal creatures. The earliest sloths were already in a good position to shift with Earth’s climate and ecological changes. The uplift of the Andes Mountains in South America led to changes on the continent as more open, drier grasslands spread where there had previously been wetter woodlands and forests. While some sloths became smaller as they spent more time around and within trees, the grasslands would host the broadest diversity of sloth species. The grasslands sloths were the ones that ballooned to exceptional sizes. Earth has been shifting between warmer and wetter times, like now, and cooler and drier climates over millions of years. The chillier and more arid times are what gave sloths their size boost. During these colder spans, bigger sloths were better able to hold on to their body heat, but they also didn’t need as much water, and they were capable of traveling long distances more efficiently thanks to their size. “The cooler and drier the climate, especially after 11.6 million years ago, led to expansive grasslands, which tends to favor the evolution of increasing body mass,” Narducci says. The combination of climate shifts, mountain uplift and vegetation changes created environments where sloths could evolve into a variety of forms—including multiple times when sloths became giants again. Gill says that large body size was a “winning strategy” for herbivores. “At a certain point, megaherbivores get so large that most predators can’t touch them; they’re able to access nutrition in foods that other animals can’t really even digest thanks to gut microbes that help them digest cellulose, and being large means you’re also mobile,” Gill adds, underscoring advantages that have repeatedly pushed animals to get big time and again. The same advantages underwrote the rise of the biggest dinosaurs as well as more recent giants like the sloths and mastodons. As large sloths could travel further, suitable grassland habitats stretched from Central America to prehistoric Florida. “This is what also allowed for their passage into North America,” Narducci says. Sloths were able to follow their favored habitats between continents. If the world were to shift back toward cooler and drier conditions that assisted the spread of the grasslands that gave sloths their size boost, perhaps similar giants could evolve. The sticking point is what humans are doing to Earth’s climate, ecosystems and existing species. The diversity and number of large species alive today is vastly, and often negatively, affected by humans. A 2019 study of human influences on 362 megafauna species, on land and in the water, found that 70 percent are diminishing in number, and 59 percent are getting dangerously close to extinction. But if that relationship were to change, either through our actions or intentions, studies like the new paper on giant sloths hint that ecosystems brimming with a wealth of megafaunal species could evolve again. Big animals change the habitats where they live, which in turn tends to support more large species adapted to those environments. The giant sloths that evolved among ancient grasslands helped to keep those spaces open in tandem with other big herbivores, such as mastodons, as well as the large carnivores that preyed upon them. Paleontologists and ecologists know this from studies of how large animals such as giraffes and rhinos affect vegetation around them. Big herbivores, in particular, tend to keep habitats relatively open. Elephants and other big beasts push over trees, trample vegetation underfoot, eat vast amounts of greenery and transport seeds in their dung, disassembling vegetation while unintentionally planting the beginnings of new habitats. Such broad, open spaces were essential to the origins of the giant sloths, and so creating wide-open spaces helps spur the evolution of giants to roam such environments. For now, we are left with the fossil record of giant animals that were here so recently that some of their bones aren’t even petrified, skin and fur still clinging to some skeletons. “The grasslands they left behind are just not the same, in ways we’re really only starting to understand and appreciate,” Gill says. A 2019 study on prehistoric herbivores in Africa, for example, found that the large plant-eaters altered the water cycling, incidence of fire and vegetation of their environment in a way that has no modern equivalent and can’t just be assumed to be an ancient version of today’s savannas. The few megaherbivores still with us alter the plant life, water flow, seed dispersal and other aspects of modern environments in their own unique ways, she notes, which should be a warning to us to protect them—and the ways in which they affect our planet. If humans wish to see the origin of new magnificent giants like the ones we visit museums to see, we must change our relationship to the Earth first. Get the latest Science stories in your inbox.

How changes in California culture have influenced the evolution of wild animals in Los Angeles

A new study argues that religion, politics and war affect how animals and plants in cities evolve, and the confluence of these forces seem to be actively affecting urban wildlife in L.A.

For decades, biologists have studied how cities affect wildlife by altering food supplies, fragmenting habitats and polluting the environment. But a new global study argues that these physical factors are only part of the story. Societal factors, the researchers claim, especially those tied to religion, politics and war, also leave lasting marks on the evolutionary paths of the animals and plants that share our cities.Published in Nature Cities, the comprehensive review synthesizes evidence from cities worldwide, revealing how human conflict and cultural practices affect wildlife genetics, behavior and survival in urban environments.The paper challenges the tendency to treat the social world as separate from ecological processes. Instead, the study argues, we should consider the ways the aftershocks of religious traditions, political systems and armed conflicts can influence the genetic structure of urban wildlife populations. (Gabriella Angotti-Jones / Los Angeles Times) “Social sciences have been very far removed from life sciences for a very long time, and they haven’t been integrated,” said Elizabeth Carlen, a biologist at Washington University in St. Louis and co-lead author of the study. “We started just kind of playing around with what social and cultural processes haven’t been talked about,” eventually focusing on religion, politics and war because of their persistent yet underexamined impacts on evolutionary biology, particularly in cities, where cultural values and built environments are densely concentrated.Carlen’s own work in St. Louis examines how racial segregation and urban design, often influenced by policing strategies, affect ecological conditions and wild animals’ access to green spaces.“Crime prevention through environmental design,” she said, is one example of how these factors influence urban wildlife. “Law enforcement can request that there not be bushes … or short trees, because then they don’t have a sight line across the park.” Although that design choice may serve surveillance goals, it also limits the ability of small animals to navigate those spaces.These patterns, she emphasized, aren’t unique to St. Louis. “I’m positive that it’s happening in Los Angeles. Parks in Beverly Hills are going to look very different than parks in Compton. And part of that is based on what policing looks like in those different places.” This may very well be the case, as there is a significantly lower level of urban tree species richness in areas like Compton than in areas like Beverly Hills, according to UCLA’s Biodiversity Atlas. A coyote wanders onto the fairway, with the sprinklers turned on, as a golfer makes his way back to his cart after hitting a shot on the 16th hole of the Harding golf course at Griffith Park. (Mel Melcon / Los Angeles Times) The study also examines war and its disruptions, which can have unpredictable effects on animal populations. Human evacuation from war zones can open urban habitats to wildlife, while the destruction of green spaces or contamination of soil and water can fragment ecosystems and reduce genetic diversity.In Kharkiv, Ukraine, for example, human displacement during the Russian invasion led to the return of wild boars and deer to urban parks, according to the study. In contrast, sparrows, which depend on human food waste, nearly vanished from high-rise areas.All of this, the researchers argue, underscores the need to rethink how cities are designed and managed by recognizing how religion, politics and war shape not just human communities but also the evolutionary trajectories of urban wildlife. By integrating ecological and social considerations into urban development, planners and scientists can help create cities that are more livable for people while also supporting the long-term genetic diversity and adaptability of the other species that inhabit them.This intersection of culture and biology may be playing out in cities across the globe, including Los Angeles.A study released earlier this year tracking coyotes across L.A. County found that the animals were more likely to avoid wealthier neighborhoods, not because of a lack of access or food scarcity, but possibly due to more aggressive human behavior toward them and higher rates of “removal” — including trapping and releasing elsewhere, and in some rare cases, killing them. In lower-income areas, where trapping is less common, coyotes tended to roam more freely, even though these neighborhoods often had more pollution and fewer resources that would typically support wild canines. Researchers say these patterns reflect how broader urban inequities are written directly into the movements of and risks faced by wildlife in the city.Black bears, parrots and even peacocks tell a similar story in Los Angeles. Wilson Sherman, a PhD student at UCLA who is studying human-black bear interactions, highlights how local politics and fragmented municipal governance shape not only how animals are managed but also where they appear. (Carolyn Cole / Los Angeles Times) “Sierra Madre has an ordinance requiring everyone to have bear-resistant trash cans,” Sherman noted. “Neighboring Arcadia doesn’t.” This kind of patchwork governance, Sherman said, can influence where wild animals ultimately spend their time, creating a mosaic of risk and opportunity for species whose ranges extend across multiple jurisdictions.Cultural values also play a role. Thriving populations of non-native birds, such as Amazon parrots and peacocks, illustrate how aesthetic preferences and everyday choices can significantly influence the city’s ecological makeup in lasting ways.Sherman also pointed to subtler, often overlooked influences, such as policing and surveillance infrastructure. Ideally, the California Department of Fish and Wildlife would be the first agency to respond in a “wildlife situation,” as Sherman put it. But, he said, what often ends up happening is that people default to calling the police, especially when the circumstances involve animals that some urban-dwelling humans may find threatening, like bears.Police departments typically do not possess the same expertise and ability as CDFW to manage and then relocate bears. If a bear poses a threat to human life, police policy is to kill the bear. However, protocols for responding to wildlife conflicts that are not life-threatening can vary from one community to another. And how police use non-lethal methods of deterrence — such as rubber bullets and loud noises — can shape bear behavior.Meanwhile, the growing prevalence of security cameras and motion-triggered alerts has provided residents with new forms of visibility into urban biodiversity. “That might mean that people are suddenly aware that a coyote is using their yard,” Sherman said. In turn, that could trigger a homeowner to purposefully rework the landscape of their property so as to discourage coyotes from using it. Surveillance systems, he said, are quietly reshaping both public perception and policy around who belongs in the city, and who doesn’t. A mountain lion sits in a tree after being tranquilized along San Vicente Boulevard in Brentwood on Oct. 27, 2022. (Wally Skalij / Los Angeles Times) Korinna Domingo, founder and director of the Cougar Conservancy, emphasized how cougar behavior in Los Angeles is similarly shaped by decades of urban development, fragmented landscapes and the social and political choices that structure them. “Policies like freeway construction, zoning and even how communities have been historically policed or funded can affect where and how cougars move throughout L.A.,” she said. For example, these forces have prompted cougars to adapt by becoming more nocturnal, using culverts or taking riskier crossings across fragmented landscapes.Urban planning and evolutionary consequences are deeply intertwined, Domingo says. For example, mountain lion populations in the Santa Monica and Santa Ana mountains have shown signs of reduced genetic diversity due to inbreeding, an issue created not by natural processes, but by political and planning decisions — such as freeway construction and zoning decisions— that restricted their movement decades ago.Today, the Wallis Annenberg Wildlife Crossing, is an attempt to rectify that. The massive infrastructure project is happening only, Domingo said, “because of community, scientific and political will all being aligned.”However, infrastructure alone isn’t enough. “You can have habitat connectivity all you want,” she said, but you also have to think about social tolerance. Urban planning that allows for animal movement also increases the likelihood of contact with people, pets and livestock — which means humans need to learn how to interact with wild animals in a healthier way.In L.A., coexistence strategies can look very different depending on the resources, ordinances and attitudes of each community. Although wealthier residents may have the means to build predator-proof enclosures, others lack the financial or institutional support to do the same. And some with the means simply choose not to, instead demanding lethal removal., “Wildlife management is not just about biology,” Domingo said. “It’s about values, power, and really, who’s at the table.”Wildlife management in the United States has long been informed by dominant cultural and religious worldviews, particularly those grounded in notions of human exceptionalism and control over nature. Carlen, Sherman and Domingo all brought up how these values shaped early policies that framed predators as threats to be removed rather than species to be understood or respected. In California, this worldview contributed not only to the widespread killing of wolves, bears and cougars but also to the displacement of American Indian communities whose land-based practices and beliefs conflicted with these approaches. A male peacock makes its way past Ian Choi, 21 months old, standing in front of his home on Altura Road in Arcadia. (Mel Melcon / Los Angeles Times) Wildlife management in California, specifically, has long been shaped by these same forces of violence, originating in bounty campaigns not just against predators like cougars and wolves but also against American Indian peoples. These intertwined legacies of removal, extermination and land seizure continue to influence how certain animals and communities are perceived and treated today.For Alan Salazar, a tribal elder with the Fernandeño Tataviam Band of Mission Indians, those legacies run deep. “What happened to native peoples happened to our large predators in California,” he said. “Happened to our plant relatives.” Reflecting on the genocide of Indigenous Californians and the coordinated extermination of grizzly bears, wolves and mountain lions, Salazar sees a clear parallel.“There were three parts to our world — the humans, the animals and the plants,” he explained. “We were all connected. We respected all of them.” Salazar explains that his people’s relationship with the land, animals and plants is itself a form of religion, one grounded in ceremony, reciprocity and deep respect. Salazar said his ancestors lived in harmony with mountain lions for over 10,000 years, not by eliminating them but by learning from them. Other predators — cougars, bears, coyotes and wolves — were also considered teachers, honored through ceremony and studied for their power and intelligence. “Maybe we had a better plan on how to live with mountain lions, wolves and bears,” he said. “Maybe you should look at tribal knowledge.”He views the Wallis Annenberg Wildlife Crossing — for which he is a Native American consultant — as a cultural opportunity. “It’s not just for mountain lions,” he said. “It’s for all animals. And that’s why I wanted to be involved.” He believes the project has already helped raise awareness and shift perceptions about coexistence and planning, and hopes that it will help native plants, animals and peoples.As L.A. continues to grapple with the future of wildlife in its neighborhoods, canyons and corridors, Salazar and others argue that it is an opportunity to rethink the cultural frameworks, governance systems and historical injustices that have long shaped human-animal relations in the city. Whether through policy reform, neighborhood education or sacred ceremony, residents need reminders that evolutionary futures are being shaped not only in forests and preserves but right here, across freeways, backyards and local council meetings.

Chun / Los Angeles Times) The research makes clear that wildlife is not simply adapting to urban environments in isolation; it is adapting to a range of factors, including policing, architecture and neighborhood design. Carlen believes this opens a crucial frontier for interdisciplinary research, especially in cities like Los Angeles, where uneven geographies, biodiversity and political decisions intersect daily. “I think there’s a lot of injustice in cities that are happening to both humans and wildlife,” she said. “And I think the potential is out there for justice to be brought to both of those things.”

Something Strange Is Happening to Tomatoes Growing on the Galápagos Islands

Scientists say wild tomato plants on the archipelago's western islands are experiencing "reverse evolution" and reverting back to ancestral traits

Something Strange Is Happening to Tomatoes Growing on the Galápagos Islands Scientists say wild tomato plants on the archipelago’s western islands are experiencing “reverse evolution” and reverting back to ancestral traits Sarah Kuta - Daily Correspondent July 9, 2025 4:29 p.m. Scientists are investigating the production of ancestral alkaloids by tomatoes in the Galápagos Islands. Adam Jozwiak / University of California, Riverside Some tomatoes growing on the Galápagos Islands appear to be going back in time by producing the same toxins their ancestors did millions of years ago. Scientists describe this development—a controversial process known as “reverse evolution”—in a June 18 paper published in the journal Nature Communications. Tomatoes are nightshades, a group of plants that also includes eggplants, potatoes and peppers. Nightshades, also known as Solanaceae, produce bitter compounds called alkaloids, which help fend off hungry bugs, animals and fungi. When plants produce alkaloids in high concentrations, they can sicken the humans who eat them. To better understand alkaloid synthesis, researchers traveled to the Galápagos Islands, the volcanic chain roughly 600 miles off the coast of mainland Ecuador made famous by British naturalist Charles Darwin. They gathered and studied more than 30 wild tomato plants growing in different places on various islands. The Galápagos tomatoes are the descendents of plants from South America that were probably carried to the archipelago by birds. The team’s analyses revealed that the tomatoes growing on the eastern islands were behaving as expected, by producing alkaloids that are similar to those found in modern, cultivated varieties. But those growing on the western islands, they found, were creating alkaloids that were more closely related to those produced by eggplants millions of years ago. Tomatoes growing on the western islands (shown here) are producing ancestral alkaloids.  Adam Jozwiak / University of California, Riverside Researchers suspect the environment may be responsible for the plants’ unexpected return to ancestral alkaloids. The western islands are much younger than the eastern islands, so the soil is less developed and the landscape is more barren. To survive in these harsh conditions, perhaps it was advantageous for the tomato plants to revert back to older alkaloids, the researchers posit. “The plants may be responding to an environment that more closely resembles what their ancestors faced,” says lead author Adam Jozwiak, a biochemist at the University of California, Riverside, to BBC Wildlife’s Beki Hooper. However, for now, this is just a theory. Scientists say they need to conduct more research to understand why tomato plants on the western islands have adapted this way. Scientists were able to uncover the underlying molecular mechanisms at play: Four amino acids in a single enzyme appear to be responsible for the reversion back to the ancestral alkaloids, they found. They also used evolutionary modeling to confirm the direction of the adaptation—that is, that the tomatoes on the western islands had indeed returned to an earlier, ancestral state. Among evolutionary biologists, “reverse evolution” is somewhat contentious. The commonly held belief is that evolution marches forward, not backward. It’s also difficult to prove an organism has reverted back to an older trait through the same genetic pathways. But, with the new study, researchers say they’ve done exactly that. “Some people don’t believe in this,” says Jozwiak in a statement. “But the genetic and chemical evidence points to a return to an ancestral state. The mechanism is there. It happened.” So, if “reverse evolution” happened in wild tomatoes, could something similar happen in humans? In theory, yes, but it would take a long time, Jozwiak says. “If environmental conditions shifted dramatically over long timescales, it’s possible that traits from our distant past could re-emerge, but whether that ever happens is highly uncertain,” Jozwiak tells Newsweek’s Daniella Gray. “It’s speculative and would take millions of years, if at all.” Get the latest stories in your inbox every weekday.

Hundreds of life-size animal puppets have begun a 20,000km (12,400 mile) journey from central Africa to the Arctic Circle as part of an ambitious project created by the team behind Little Amal, the giant puppet of a Syrian girl that travelled across the world.The public art initiative called The Herds, which has already visited Kinshasa and Lagos, will travel to 20 cities over four months to raise awareness of the climate crisis.It is the second major project from The Walk Productions, which introduced Little Amal, a 12-foot puppet, to the world in Gaziantep, near the Turkey-Syria border, in 2021. The award-winning project, co-founded by the Palestinian playwright and director Amir Nizar Zuabi, reached 2 million people in 17 countries as she travelled from Turkey to the UK.The Herds’ journey began in Kinshasa’s Botanical Gardens on 10 April, kicking off four days of events. It moved on to Lagos, Nigeria, the following week, where up to 5,000 people attended events performed by more than 60 puppeteers.On Friday the streets of Dakar in Senegal will be filled with more than 40 puppet zebras, wildebeest, monkeys, giraffes and baboons as they run through Médina, one of the busiest neighbourhoods, where they will encounter a creation by Fabrice Monteiro, a Belgium-born artist who lives in Senegal, and is known for his large-scale sculptures. On Saturday the puppets will be part of an event in the fishing village of Ngor.The Herds’ 20,000km journey began in Kinshasa, the Democratic Republic of the Congo. Photograph: Berclaire/walk productionsThe first set of animal puppets was created by Ukwanda Puppetry and Designs Art Collective in Cape Town using recycled materials, but in each location local volunteers are taught how to make their own animals using prototypes provided by Ukwanda. The project has already attracted huge interest from people keen to get involved. In Dakar more than 300 artists applied for 80 roles as artists and puppet guides. About 2,000 people will be trained to make the puppets over the duration of the project.“The idea is that we’re migrating with an ever-evolving, growing group of animals,” Zuabi told the Guardian last year.Zuabi has spoken of The Herds as a continuation of Little Amal’s journey, which was inspired by refugees, who often cite climate disaster as a trigger for forced migration. The Herds will put the environmental emergency centre stage, and will encourage communities to launch their own events to discuss the significance of the project and get involved in climate activism.The puppets are created with recycled materials and local volunteers are taught how to make them in each location. Photograph: Ant Strack“The idea is to put in front of people that there is an emergency – not with scientific facts, but with emotions,” said The Herds’ Senegal producer, Sarah Desbois.She expects thousands of people to view the four events being staged over the weekend. “We don’t have a tradition of puppetry in Senegal. As soon as the project started, when people were shown pictures of the puppets, they were going crazy.”Little Amal, the puppet of a Syrian girl that has become a symbol of human rights, in Santiago, Chile on 3 January.

Dead, sick pelicans turning up along Oregon coast

So far, no signs of bird flu but wildlife officials continue to test the birds.

Sick and dead pelicans are turning up on Oregon’s coast and state wildlife officials say they don’t yet know why. The Oregon Department of Fish and Wildlife says it has collected several dead brown pelican carcasses for testing. Lab results from two pelicans found in Newport have come back negative for highly pathogenic avian influenza, also known as bird flu, the agency said. Avian influenza was detected in Oregon last fall and earlier this year in both domestic animals and wildlife – but not brown pelicans. Additional test results are pending to determine if another disease or domoic acid toxicity caused by harmful algal blooms may be involved, officials said. In recent months, domoic acid toxicity has sickened or killed dozens of brown pelicans and numerous other wildlife in California. The sport harvest for razor clams is currently closed in Oregon – from Cascade Head to the California border – due to high levels of domoic acid detected last fall.Brown pelicans – easily recognized by their large size, massive bill and brownish plumage – breed in Southern California and migrate north along the Oregon coast in spring. Younger birds sometimes rest on the journey and may just be tired, not sick, officials said. If you find a sick, resting or dead pelican, leave it alone and keep dogs leashed and away from wildlife. State wildlife biologists along the coast are aware of the situation and the public doesn’t need to report sick, resting or dead pelicans. — Gosia Wozniacka covers environmental justice, climate change, the clean energy transition and other environmental issues.
