- 0:00Speaker 1: Welcome. This is Rebecca Shore for Radio Eye, and today
- 0:04Speaker 1: I will be reading the Smithsonian Magazine, dated September-October 2026.
- 0:09Speaker 1: As a reminder, Radio Eye is a reading service intended
- 0:13Speaker 1: for people who are blind or have other disabilities that
- 0:16Speaker 1: make it difficult to read printed material. Please join me
- 0:19Speaker 1: now for the first article titled, Africa's Wild Dogs Are
- 0:23Speaker 1: the Most Hated Carnivores on the Continent. Here's Why Some
- 0:27Speaker 1: Conservationists Are Saving Them Anyway. Meet the team that closely
- 0:32Speaker 1: monitors the playful canines, which need help to form diverse
- 0:36Speaker 1: packs and stop their numbers from dwindling. By Helen Sullivan
- 0:41Speaker 1: Two white pickup trucks are parked beside a highway that
- 0:44Speaker 1: cuts through Waterburg, a South African municipality, three hours from Johannesburg.
- 0:50Speaker 1: Passing the trucks on foot, you might hear something that
- 0:53Speaker 1: makes you stop. Their cargo is panting. just visible through
- 0:58Speaker 1: the holes at the top of three green wooden crates
- 1:01Speaker 1: as fur over rib cages, mottled black, white, and gold,
- 1:05Speaker 1: rising and falling. The three sleeping female African wild dogs, sisters,
- 1:11Speaker 1: have traveled a long way in the past few weeks,
- 1:14Speaker 1: even by the standards of their species, which can cover
- 1:17Speaker 1: 30 miles a day and occupy ranges of 1,000 miles.
- 1:22Speaker 1: They arrived by plane from Karangani Game Reserve in Mozambique,
- 1:26Speaker 1: courtesy of the Endangered Wildlife Trust's African Wild Dog Range
- 1:30Speaker 1: Expansion Program. The project, which started in 1997, has increased
- 1:36Speaker 1: the world's wild dog population by more than 344 in
- 1:41Speaker 1: 29 years. It introduces dogs to wildlife reserves in countries
- 1:46Speaker 1: where they haven't been seen in decades. For instance, Mozambique,
- 1:51Speaker 1: where the species disappeared during a civil war that lasted
- 1:54Speaker 1: from 1977 to 1992. The Mozambican packs have bred so
- 2:00Speaker 1: successfully that the Endangered Wildlife Trust, EWT, is now bringing
- 2:05Speaker 1: young dogs to South Africa to form new, genetically diverse
- 2:09Speaker 1: packs here. The three sisters have been darted with sedatives,
- 2:14Speaker 1: a risky but necessary step in moving them to their
- 2:17Speaker 1: new home for the next few weeks, a state-of-the-art enclosure,
- 2:20Speaker 1: or BOMA, the first designed specifically to hold their species
- 2:25Speaker 1: before they're released with tracking collars into the wild. The
- 2:30Speaker 1: sisters represent a not insignificant portion of 6,600 African wild
- 2:35Speaker 1: dogs left in the world. According to the World Wildlife Fund,
- 2:40Speaker 1: the animals are among the world's most endangered. Also known
- 2:44Speaker 1: as cape-hunting or painted dogs, they resemble large gangly mongrels
- 2:49Speaker 1: with extremities picked from a safari odds-and-ends bin big disc-shaped
- 2:54Speaker 1: black ears, large paws on skinny legs, and fluffy white tails.
- 2:59Speaker 1: Each dog's fur has a clearly unique pattern of black, gold,
- 3:03Speaker 1: and white splotches, more abstract impressionist than the designs that
- 3:08Speaker 1: cover snakes, zebras, or leopards. Wild dogs are the most
- 3:12Speaker 1: successful hunters in Africa, with a kill rate of 80%. Lions,
- 3:17Speaker 1: by comparison, kill just 30% of what they hunt. The
- 3:21Speaker 1: dog's superpower is also part of the reason they are
- 3:24Speaker 1: so threatened. Owners of many private game reserves would rather
- 3:28Speaker 1: kill them than lose expensive game. Subsistence farmers feel the
- 3:33Speaker 1: same way about their livestock. A 2021 study published in
- 3:37Speaker 1: Ecology and Evolution showed that human causes, including direct killing
- 3:42Speaker 1: and diseases from domestic dogs, accounted for 44% of all
- 3:47Speaker 1: wild dog deaths at study sites in Kenya and Botswana,
- 3:51Speaker 1: and Zimbabwe over a 15-year period. A lack of continuity
- 3:56Speaker 1: between areas where the dogs are welcome means that, without intervention,
- 4:00Speaker 1: they struggle to find mates. But there is much to
- 4:03Speaker 1: love about the most hated carnivore in Africa. Ask a
- 4:07Speaker 1: wild dog enthusiast what they enjoy the most, and they
- 4:11Speaker 1: will likely say it is the dog's playfulness. Brianna Abrams,
- 4:15Speaker 1: who researches wild dogs in Botswana, has seen that pups
- 4:19Speaker 1: are Bat around balls of elephant dung like a football,
- 4:22Speaker 1: she said. Neil Jordan, a biologist at the University of
- 4:26Speaker 1: New South Wales in Australia, discovered that wild dogs are
- 4:30Speaker 1: one of the few species on earth that appear to vote.
- 4:34Speaker 1: Before departing on a hunt, the animals hold rallies. At dusk,
- 4:39Speaker 1: one or two will stand up after resting in the
- 4:41Speaker 1: heat and pull their ears back, pretending to stalk prey.
- 4:45Speaker 1: They'll make strange, strangled barks and shittering noises. curling their tongues,
- 4:50Speaker 1: playing with one another, and urinating. And then they kind
- 4:54Speaker 1: of snowball socially, so then more get involved and more
- 4:57Speaker 1: get involved. It's like a big merry-go-round, and they're all
- 5:01Speaker 1: running around like crazy, Jordan says. Typically, they'll do this once,
- 5:05Speaker 1: then lie back down, then again, then lie back down.
- 5:10Speaker 1: Only when they emit rapid nasal exhalations or sneezes will
- 5:14Speaker 1: they actually depart. We still don't know for sure whether
- 5:18Speaker 1: the dogs are using that, or it just happens to
- 5:21Speaker 1: be occurring around the same time, as they're signaling their
- 5:24Speaker 1: intention to move in another way, Jordan emphasizes. Wild dogs
- 5:29Speaker 1: also allow their pups to feed first, near unique behavior
- 5:33Speaker 1: among animals, says Jordan. When a member of the pack
- 5:37Speaker 1: is injured or sick or heavily pregnant and can't join
- 5:40Speaker 1: a hunt, another dog will regurgitate food for it. Wild
- 5:44Speaker 1: dogs look out for one another. While the sisters doze
- 5:48Speaker 1: in the trucks, I take a seat in a hut
- 5:50Speaker 1: nearby with Eugene Grayling, one of the EWT field officers
- 5:55Speaker 1: transporting the dogs. We are sitting at the entrance to
- 5:59Speaker 1: the Welgevonden Game Reserve, which houses the enclosure that will
- 6:03Speaker 1: temporarily contain the dogs. South Africa has four main wild
- 6:07Speaker 1: dog populations. The first is in captivity and private zoos.
- 6:12Speaker 1: Then there is the population in Kruger National Park, which
- 6:16Speaker 1: is the only place in the country with enough dogs
- 6:19Speaker 1: to maintain themselves genetically. The third is the free-ranging population,
- 6:24Speaker 1: roaming across a patchwork of private and public lands in
- 6:27Speaker 1: the Waterberg. Finally, there is a metapopulation, whose members are
- 6:32Speaker 1: tracked as they travel through nature reserves such as Welgewanden
- 6:37Speaker 1: or the Tsvali Kalahari Reserve, South Africa's largest privately owned
- 6:41Speaker 1: nature reserve. EWT works with the reserves to create new,
- 6:46Speaker 1: genetically diverse packs and expand their range. Wild dog packs,
- 6:52Speaker 1: which consist of between 5 and 20 individuals, have complicated
- 6:56Speaker 1: social structures, says Grayling. At the top is the alpha female.
- 7:00Speaker 1: She and the alpha male are the only dogs in
- 7:03Speaker 1: the pack who breed. In order for populations to grow,
- 7:07Speaker 1: dogs must form new packs. A group of sisters will
- 7:11Speaker 1: set off in one direction and in search of males
- 7:13Speaker 1: from another pack, while a group of brothers does the
- 7:17Speaker 1: same in a different direction. The EWT carefully monitors dispersal
- 7:22Speaker 1: and the pack's genetics. The lack of continuity between ranges
- 7:26Speaker 1: means the animals are likely to get stuck without a mate.
- 7:30Speaker 1: Conservationists can't afford to let sleeping dogs lie. The three
- 7:35Speaker 1: sisters in the truck, for example, had found mates back
- 7:39Speaker 1: in Mozambique who were too closely related. We had to
- 7:42Speaker 1: think hard about how to manage that because technically the
- 7:45Speaker 1: dogs had done everything right, says Cole Duplessis, who coordinates
- 7:50Speaker 1: the range expansion project. If you told people 20 years
- 7:55Speaker 1: ago that we were going to be flying wild dogs
- 7:58Speaker 1: under sedation to other countries, it's just quite crazy. At
- 8:03Speaker 1: Welga Vanden, Grayling and I are joined in the hut
- 8:07Speaker 1: by Riley Mooney, a biologist and and the director of
- 8:10Speaker 1: the Waterberg Wild Dog Initiative. Mooney has traveled farther than
- 8:14Speaker 1: the dogs. She came from Wisconsin to South Africa originally
- 8:19Speaker 1: to study primates. During the COVID-19 pandemic, her regular research
- 8:24Speaker 1: shut down, and she attended a community meeting about free-roaming
- 8:29Speaker 1: dogs that had been mostly left to their own devices.
- 8:33Speaker 1: It was a very volatile situation, Mooney says. Locals were
- 8:37Speaker 1: calling for someone to bridge the gap between communities and conservationists,
- 8:41Speaker 1: and Mooney was the right person for the job. The
- 8:44Speaker 1: first thing on her to-do list was to find out
- 8:47Speaker 1: how many dogs there were. Their coats made them relatively
- 8:51Speaker 1: easy to identify and keep track of. We can say
- 8:55Speaker 1: with pretty good confidence that in this entire Waterbrook area,
- 8:59Speaker 1: there are only 27 wild dogs, she says. In the hut,
- 9:04Speaker 1: Grayling gets a call from Joseph Hilako, his colleague at
- 9:07Speaker 1: the EWT who has been keeping an eye on the
- 9:10Speaker 1: sleeping dogs. Halako, the EWT's conflict mitigation officer, grew up
- 9:17Speaker 1: in the area and has family who farm. He speaks
- 9:21Speaker 1: Northern Sutu, among other South African languages, and has an
- 9:25Speaker 1: insider's knowledge about what will and won't work when it
- 9:28Speaker 1: comes to dogs and people. Building trust and maintaining relationships
- 9:32Speaker 1: make the biggest factor, he says. And, you know, a
- 9:35Speaker 1: familiar face works better than any face, he says. After
- 9:40Speaker 1: Grayling leaves the hut, he drives back past us. One
- 9:43Speaker 1: of the dogs seems to be overheating, he says. He
- 9:46Speaker 1: wants to get her to the enclosure right away and
- 9:49Speaker 1: cool her down. Moony and I jump into her car
- 9:52Speaker 1: and follow Grayling. We cross the highway, passing cattle and
- 9:56Speaker 1: thick bushland, until we come to the boma. A couple
- 9:59Speaker 1: of shipping containers and a fence. It doesn't seem like much,
- 10:04Speaker 1: but Duplessis designed everything in the boma specifically and simply
- 10:08Speaker 1: for wild dogs. At the base of the fences is
- 10:11Speaker 1: a concrete wall that extends four feet into the ground.
- 10:15Speaker 1: Wild dogs are determined diggers. The enclosure is split so
- 10:20Speaker 1: that males and females can be kept apart, bonding over
- 10:23Speaker 1: time through the fence. And in each section is a
- 10:26Speaker 1: feeding post. The dogs tend to eat facing you, Mooney explains,
- 10:31Speaker 1: which makes it hard to dart them for transportation. But
- 10:34Speaker 1: if their food is tied to a post, and behind
- 10:37Speaker 1: the post is a small wooden wall, the dogs are
- 10:40Speaker 1: forced to eat with their behinds toward you. Conveniently, they
- 10:44Speaker 1: raise their hind quarters in the air while eating, which
- 10:47Speaker 1: makes for a safer and easier shot. As we help
- 10:51Speaker 1: Grayling and Halako lift a crate off the pickup, a
- 10:54Speaker 1: dusty paw flops out of one corner, and I think
- 10:57Speaker 1: of something my uncle says. You can smell the world
- 11:00Speaker 1: in a dog's paw. Mooney and I back away, watching
- 11:04Speaker 1: from inside a container, as Halako moves the car so
- 11:08Speaker 1: that the overheating dog is in the shade. Though it
- 11:11Speaker 1: is late afternoon, the temperature is still around ninety degrees.
- 11:16Speaker 1: Halako and Grayling release the dogs one at a time,
- 11:20Speaker 1: opening the crate and waiting until a dog walks, then
- 11:23Speaker 1: trots out. The first is less sure on her feet,
- 11:27Speaker 1: the second seems almost normal, until Moony points out that
- 11:31Speaker 1: she would have run much faster from the crate and
- 11:33Speaker 1: people had she not been a bit dozy. The sisters
- 11:37Speaker 1: stand together in a grassy area, point their noses in
- 11:40Speaker 1: the air, move their satellite dish ears, and lie down
- 11:44Speaker 1: under a thorn tree. It has been a long day.
- 11:49Speaker 1: The sun is about to set, and I need to
- 11:51Speaker 1: leave before the park gates close. I prepare to say
- 11:54Speaker 1: goodbye and walk over to the overheating dog, who is
- 11:57Speaker 1: lying next to the water. She hasn't stood up. She
- 12:01Speaker 1: is breathing, her mouth is open, and Grayling tries to
- 12:04Speaker 1: reassure everyone that she'll be all right, but he doesn't
- 12:08Speaker 1: sound too sure. Later, he gives me news that the
- 12:12Speaker 1: dog died. It is the first time this has happened
- 12:15Speaker 1: on his watch, and it comes as a shock. The
- 12:18Speaker 1: cause of death is determined to be capture myopathy or
- 12:22Speaker 1: broken heart syndrome, says Duplessis. It is caused by heightened stress.
- 12:28Speaker 1: In this case, the known factors were the stress of
- 12:30Speaker 1: being captured, which involved hours of people trying to dart her,
- 12:35Speaker 1: and the high temperature that day. There may have been
- 12:39Speaker 1: been underlying physical factors or there may have been predators
- 12:43Speaker 1: like hyenas nearby in the nights before the move but
- 12:47Speaker 1: duplessis is focused on what the ewt could control i
- 12:51Speaker 1: would never accept the loss of a dog as fine
- 12:53Speaker 1: he says but if one of the surviving sisters goes
- 12:57Speaker 1: on to have puppies and the population grows by 20
- 13:00Speaker 1: to 30 dogs in her lifetime then it makes it
- 13:03Speaker 1: seem a little better he says A year later, Duplessis
- 13:07Speaker 1: updates me on the two surviving sisters. After keeping them
- 13:11Speaker 1: for two months at the Boma, near Welga Vanden, Duplessis
- 13:15Speaker 1: sent them to a small private game reserve called Reetspruit,
- 13:19Speaker 1: which is connected to Kruger National Park. He knew of
- 13:22Speaker 1: an eligible bachelor living just nine hours away in KwaZulu-Natal province.
- 13:28Speaker 1: Duplessis darted the mail and drove him to Reetspruit. The
- 13:31Speaker 1: bonding between those dogs went extremely well, and we had
- 13:35Speaker 1: this new pack of three, he says. They were hunting successfully.
- 13:39Speaker 1: Everything was really good. And then, in October last year,
- 13:43Speaker 1: that male was killed by a lion on the reserve.
- 13:47Speaker 1: A couple more months passed, and Duplessis heard of two
- 13:50Speaker 1: other males who had dispersed from a pack looking for mates.
- 13:54Speaker 1: He darted them, put them in the boma, and waited
- 13:57Speaker 1: for the sisters to show up. A few days later,
- 14:00Speaker 1: the females, now roaming free and wearing collars, showed up
- 14:04Speaker 1: near one of the reserve's lodges. Duplessis drove to where
- 14:08Speaker 1: they were and attached two balls of hay from the
- 14:10Speaker 1: boma saturated with the male's scent to the back of
- 14:14Speaker 1: his car. He performed who-calls, mimicking sounds the dogs make
- 14:19Speaker 1: to find each other. The females emerged. Then he started
- 14:23Speaker 1: to drive. We were at one point going sixty kilometers
- 14:26Speaker 1: an hour, about thirty-seven miles per hour, While these females
- 14:30Speaker 1: were keeping up trying to get to this ball of grass,
- 14:33Speaker 1: he says, it was one of the coolest things I've
- 14:35Speaker 1: done in my wild dog career. Relocations don't work if
- 14:40Speaker 1: the dog's range doesn't keep expanding and community education efforts
- 14:45Speaker 1: don't continue. But over the past three decades, the amount
- 14:49Speaker 1: of land set aside for the dogs has grown by 1.5
- 14:53Speaker 1: million hectares, and there are 30 more packs than before.
- 14:58Speaker 1: This genetic diversity within those packs is very good, Duplessis says.
- 15:03Speaker 1: If we can keep this strong and working, and other
- 15:06Speaker 1: organizations are doing their restoration efforts and community conservation efforts,
- 15:11Speaker 1: it's creating the space where we're ready to jump when
- 15:14Speaker 1: the time is right. A short way from the enclosure,
- 15:18Speaker 1: Duplessis dropped the hay and sped off, trusting that the
- 15:22Speaker 1: females would find their way to the males. And they did.
- 15:26Speaker 1: They wasted no time flirting through the fence as wild
- 15:29Speaker 1: dogs do, ducking under each other, dipping their heads. Duplessis
- 15:33Speaker 1: decided to release the males from the boma. But instead
- 15:37Speaker 1: of the males coming out, the females ran in and
- 15:40Speaker 1: all four refused to emerge. So he left them to
- 15:44Speaker 1: get to know one another in the enclosure for three weeks.
- 15:48Speaker 1: The week Duplessis and I spoke, the females had started
- 15:51Speaker 1: estrus and the males were showing mate-guarding behavior. in a
- 15:55Speaker 1: few months, with any luck, puppies. When we speak a
- 15:59Speaker 1: few months later, Duplessis tells me one of the sisters
- 16:02Speaker 1: did get pregnant. The pack of four made a den,
- 16:06Speaker 1: something that happens only a day or so before a
- 16:08Speaker 1: female gives birth, but in the next few weeks a
- 16:11Speaker 1: leopard attacked and killed the female. The puppies were too
- 16:15Speaker 1: young to survive without her milk and died too, and
- 16:19Speaker 1: the remaining three went on the run again all the
- 16:22Speaker 1: way out of the park. The brothers were caught in
- 16:24Speaker 1: a snare line and died, and the last surviving sister
- 16:29Speaker 1: eventually joined another pack. I ask Duplessis how he manages
- 16:34Speaker 1: to not get too discouraged. To me, it's about population trend,
- 16:38Speaker 1: he says. Even if half of them make it, the
- 16:41Speaker 1: point is the trend is growing. In 2025, the dogs
- 16:46Speaker 1: the project looks after in South Africa, Mozambique, and Malawi
- 16:51Speaker 1: had 150 puppies altogether. With only 700 breeding pairs and 6,600
- 16:57Speaker 1: wild dogs left, 150 is quite substantial, Duplessis says. You
- 17:03Speaker 1: have ebbs and flows, but at the end of each year,
- 17:07Speaker 1: if you're either stable or increasing, for an endangered species,
- 17:11Speaker 1: you're doing pretty well. And accompanying this article, did you know,
- 17:17Speaker 1: where do wild dogs fall in their family tree? DNA
- 17:22Speaker 1: evidence suggests that African wild dogs split off from wolves, jackals,
- 17:27Speaker 1: and coyotes around 1.7 million years ago, making this species
- 17:33Speaker 1: one of the older branches of the dog family tree.
- 17:37Speaker 1: A pack of African wild dogs can bring down prey
- 17:41Speaker 1: up to 10 times its own body weight. Next, Spain's
- 17:47Speaker 1: white-headed ducks have a signature color right in the name,
- 17:51Speaker 1: and that isn't even their most remarkable hue. The first
- 17:54Speaker 1: thing you're likely to notice is the blue bill, but
- 17:57Speaker 1: beyond appearances, the duck has an exciting story to tell
- 18:01Speaker 1: about conservation and recovery. By Cheryl Katz From their whisk-broom
- 18:07Speaker 1: tails to males' bright sky-blue bills, white-headed ducks are among
- 18:12Speaker 1: the oddest in the world. Mild-mannered outside of breeding season,
- 18:17Speaker 1: they star in a spectacular springtime courtship display, in the
- 18:20Speaker 1: wetlands of Europe, North Africa, the Middle East, and Central Asia.
- 18:25Speaker 1: Come spring, males perform a series of intricate dances that
- 18:30Speaker 1: include sideways swimming, exuberant splashing, and beating their puffed up
- 18:34Speaker 1: neck feathers with their bills to produce bubble trails. Their
- 18:38Speaker 1: exceptionally long and stiff tail feathers are part of the show,
- 18:42Speaker 1: waving like flags, spreading like fans, and slapping the water
- 18:46Speaker 1: like paddles. To witness white-headed ducks in courtship is to
- 18:51Speaker 1: watch one of the avian world's most extraordinary performances, says
- 18:55Speaker 1: Niki Petkov, a waterfowl expert with both the Bulgarian Society
- 19:00Speaker 1: for the Protection of Birds and BirdLife International, an arm
- 19:04Speaker 1: of the International Union for Conservation of Nature, IUCN. In Spain,
- 19:11Speaker 1: white-headed ducks also star in a spectacular conservation success story.
- 19:16Speaker 1: Decades of draining wetlands for agriculture and development in the
- 19:21Speaker 1: past century shrank habitat and tanked numbers across the duck's range.
- 19:26Speaker 1: Hunting took a further toll on the global population, which
- 19:29Speaker 1: had been estimated at some 100,000 in the 1930s. By
- 19:34Speaker 1: the late 1970s, most European populations had gone extinct, and
- 19:39Speaker 1: in Spain, only 22 birds remained at a single location.
- 19:44Speaker 1: That shocking tally launched a national campaign to restore and
- 19:48Speaker 1: protect wetlands, improve water management, and ban hunting. Spain's white-headed
- 19:54Speaker 1: duck population has now rebounded to some 2,500 and expanded
- 19:59Speaker 1: across the country. Elsewhere, however, the story isn't as upbeat. Globally,
- 20:06Speaker 1: the species continues to decline, and is listed as endangered
- 20:10Speaker 1: on the IUCN Red List. Sizable populations in the eastern
- 20:15Speaker 1: part of the duck's range receive little protection. Pollution, water loss,
- 20:20Speaker 1: and other effects of human activities continue to destroy their habitats.
- 20:25Speaker 1: What's more, another threat has emerged, ruddy ducks. Specimens of
- 20:31Speaker 1: this invasive American species escaped from a British wildlife reserve
- 20:35Speaker 1: and spread eastward. Reaching Spain's white-headed duck breeding grounds in
- 20:40Speaker 1: the 1980s, the aggressive foreigners beat out native males for mates.
- 20:45Speaker 1: By the early 1990s, fertile hybrids proved as dominant as
- 20:50Speaker 1: their ruddy duck progenitors, raising fears that interbreeding would drive
- 20:54Speaker 1: white-headed ducks to genetic extinction. In Western Europe, a ruddy
- 20:59Speaker 1: duck cull campaign now has the hybridization threat under control. However,
- 21:05Speaker 1: the risk of recurrence remains. Although white-headed ducks have made
- 21:10Speaker 1: a heartening comeback in the West, their future depends on
- 21:13Speaker 1: preserving wetlands throughout their range. A new multinational initiative began
- 21:18Speaker 1: this fall in southeastern Europe, the eastern Mediterranean, and Central
- 21:23Speaker 1: Asia to expand that effort. Meanwhile, climate change and increasing
- 21:27Speaker 1: droughts put wetlands worldwide at risk of drying out. Describing
- 21:32Speaker 1: the white-headed duck as a conservation success story requires an
- 21:37Speaker 1: important caveat, Petkoff cautions. The story is not finished. Fun fact.
- 21:43Speaker 1: What to know about the white-headed duck. Female white-headed ducks
- 21:48Speaker 1: are attracted to males with the brightest blue bills, which
- 21:51Speaker 1: are considered a sign of virility. During mating season, hormones
- 21:56Speaker 1: alter the microscopic structure of the bill's outer keratin layer,
- 22:00Speaker 1: giving them a blue appearance. Once mating season ends, The
- 22:05Speaker 1: bills returned to a grayish color. Next. We've been strapping
- 22:10Speaker 1: cargo to our backs for millions of years, but backpack
- 22:14Speaker 1: innovation really took off around the Civil War. Discover the
- 22:18Speaker 1: origin story for an accessory being comfortably lugged by nearly
- 22:21Speaker 1: every hiker and student, with about 450 million sold each year,
- 22:26Speaker 1: by Katya Singal. Humans have been carting things on our
- 22:31Speaker 1: back in wraps of some kind, at least since we
- 22:34Speaker 1: began using tools, around two million years ago, and we
- 22:37Speaker 1: have always sought ways to make the load more comfortable.
- 22:41Speaker 1: The oldest known backpack ever discovered, in the Alps on
- 22:45Speaker 1: the border between Austria and Italy, employed two narrow wooden
- 22:49Speaker 1: boards and a hazel rod for a frame. The contraption
- 22:53Speaker 1: dates to around 3300 BC and is credited to Ötzi,
- 22:58Speaker 1: the iceman, a glacier mummy unearthed alongside it in 1991.
- 23:04Speaker 1: But what we recognize as a backpack is much newer.
- 23:07Speaker 1: In 1865, Henry Clay Merriam led a regiment of Black
- 23:12Speaker 1: Union troops in an attack against Fort Blakely, a Confederate
- 23:16Speaker 1: stronghold in Alabama. His deeds in this final battle of
- 23:20Speaker 1: the Civil War earned him a Medal of Honor for
- 23:23Speaker 1: conspicuous gallantry. Afterward, the lieutenant colonel had an epiphany. It
- 23:29Speaker 1: was burdensome to carry both a knapsack, a pack with
- 23:32Speaker 1: shoulder straps but no frame for internal support, and a haversack,
- 23:37Speaker 1: a shoulder bag containing his rations. Based on his time
- 23:41Speaker 1: carrying gear for the Army, Merriam devised a solution, a
- 23:46Speaker 1: boxy canvas pack with room for socks, a quart of water,
- 23:50Speaker 1: a shaving kit and a deck of cards, plus a
- 23:53Speaker 1: compartment for rations and a case at the bottom. Sheet
- 23:57Speaker 1: metal braces formed the bag's frame, and could double as
- 24:00Speaker 1: tent poles at night. In his 1878 patent, Merriam explained
- 24:06Speaker 1: that the design helped soldiers by lessening the weight to
- 24:09Speaker 1: be carried and at the same time disposing it more
- 24:12Speaker 1: uniformly and leaving the body of the soldier freer and
- 24:16Speaker 1: less hampered by straps and other fastenings. The tent poles
- 24:21Speaker 1: were especially inventive, but improvements were still to be made.
- 24:26Speaker 1: In 1882, Camille Poirier's owner of a shoe shop in Duluth, Minnesota,
- 24:31Speaker 1: used a canvas design with a head strap to carry
- 24:34Speaker 1: a canoe and pack simultaneously, a priority in the land
- 24:38Speaker 1: of 10,000 lakes. He also devised a further strap that
- 24:42Speaker 1: held an umbrella to shade hikers. An early advertisement breathlessly
- 24:47Speaker 1: urged readers to hit the trail with the sack that
- 24:50Speaker 1: has made history in the northern wilds. Marketed to the
- 24:54Speaker 1: fast-growing number of recreational outdoorsmen, The style proved both popular
- 24:59Speaker 1: and enduring. The Poirier or Duluth pack is still produced today.
- 25:05Speaker 1: Further refinements followed. After Norwegian outdoorsman Ole F. Bergen added
- 25:11Speaker 1: a curved metal frame to a backpack in 1909, his
- 25:16Speaker 1: country's armed forces adopted his packs, and the legendary Norwegian
- 25:20Speaker 1: explorer and mountaineer Roald Amundsen took one on a South
- 25:24Speaker 1: Pole expedition. Lloyd F. Nelson drew inspiration from the packs
- 25:29Speaker 1: carried by Inuit he encountered while hiking across Alaska to
- 25:33Speaker 1: stake a land claim. In 1922, he crafted the original
- 25:37Speaker 1: Trapper Nelson, a canvas bag with a detachable wood frame
- 25:42Speaker 1: and steel pens. The modern backpack began to take its
- 25:45Speaker 1: true shape in the 1930s after Jerry Cunningham, a mountaineer
- 25:50Speaker 1: who went on to serve with the 10th Mountain Division,
- 25:54Speaker 1: added zippered compartments for easy access while rock climbing. Cunningham
- 25:58Speaker 1: switched to manufacturing nylon models in 1967. That same year,
- 26:04Speaker 1: Murray McCorry established Jansport with his girlfriend Jan Lewis, offering
- 26:09Speaker 1: nylon packs with lightweight aluminum frames. The skiing and mountaineering
- 26:14Speaker 1: packs proved popular, with college students looking for a way
- 26:18Speaker 1: to keep their books dry in rainy Seattle, where Jansport
- 26:22Speaker 1: had set up shop. The lighter frames produced by Cunningham
- 26:25Speaker 1: and by Jansport transformed these packs from a mountaineering accessory
- 26:30Speaker 1: to an essential back-to-school item. Styles may change, recycled materials,
- 26:36Speaker 1: and USB charging ports are trending. Fans of flair can
- 26:40Speaker 1: buy models with a sparkle and glitter finish, but the
- 26:43Speaker 1: backpack remains invaluable to any and all wanderers. Around 450
- 26:49Speaker 1: million are sold globally each year. Roughly the total number
- 26:54Speaker 1: of iPods sold anywhere, ever, a stunning testament to the
- 26:58Speaker 1: backpack's ability to adapt. And accompanying this article, Did You Know?
- 27:03Speaker 1: Meet Utsi, the Iceman. Discovered in 1991 and preserved by
- 27:10Speaker 1: glacial ice, Utsi is the oldest naturally preserved human mummy
- 27:15Speaker 1: ever found in Europe, at roughly 5,300 years old. In
- 27:18Speaker 1: his possession, was one of the oldest copper axes ever found,
- 27:26Speaker 1: a 99.7% pure copper blade with a handle made from yew.
- 27:34Speaker 1: Researchers have enumerated 61 tattoos on Ötzi, identified by rubbing
- 27:40Speaker 1: charcoal into abrasions in the skin. Just hours before he died,
- 27:46Speaker 1: Ötzi ate an omnivorous feast, comprising meat from an ibex,
- 27:52Speaker 1: and a red deer, plus single-grain wheat and a quantity
- 27:56Speaker 1: of animal fat. This concludes readings from the Smithsonian Magazine
- 28:03Speaker 1: for today. Your reader has been Rebecca Shore. Thank you
