https://www.imdb.com/title/tt31971270/?ref_=fn_all_ttl_1 Mammals (2024) [BBC.iPlayer] [4K-HLG] --- Series 1: 1. Dark The night might be a time we avoid, but for the majority of mammals it has always been a world of opportunity. Mammals first emerged two hundred million years ago, during the time of the dinosaurs. To avoid competition with these mighty rivals, they stayed small and only active at night. And many have since chosen to stay there, becoming masters of the shadows. Today, more than two-thirds of mammal species are nocturnal. We uncover the intriguing strategies they have evolved, from remarkable senses to teamwork, intelligence and adaptability, that have enabled them to overcome a time we find so challenging. Nocturnal mammals have developed an array of sharp senses. And, unlike us, many are blessed with incredible night vision. A leopard’s sight is so sensitive, it can see even on the darkest of nights, helping it target prey as they sleep high up in the treetops. In the empty expanse of the Sahara, fennec foxes’ enormous ears and remarkable hearing help them to track down their elusive quarry, even those hiding under the sand. The Etruscan shrew, the smallest terrestrial mammal in the world, has honed one of the most ancient senses of all to hunt. With its incredibly sensitive whiskers, it successfully uses touch to find its prey, often as big as itself, hiding in the undergrowth. And an amorous armadillo’s acute sense of smell isn’t just used to find food in the dark. They also use it to communicate, sending secret scented messages to each other in the breeding season - with humorous results. But it’s when mammals combine these remarkable senses and work together as a team that they achieve the most incredible feats in the dark. In Ngorongoro crater in Tanzania, where some of the largest clans of hyena in Africa are found, hyenas combine forces, hunting together at night, enabling them to overpower one of the largest and most dangerous animals in Africa – the Cape buffalo. Underground in the Kalahari Desert, one of the stranger mammals, the Damaraland mole rat, has taken teamwork to a whole new level. These mole rats have found an intriguing way to overcome a subterranean life in permanent darkness. But there is one night-time mammal success story that is above all others. Bats, the only mammal able to fly, have mastered the night skies almost everywhere on Earth, thanks to their ability to fly and to echolocate. Echolocation is nature’s sonar, enabling them to create a mental map of their surroundings even in pitch black. And some use this seemingly supernatural power to hunt the most unexpected prey. Off the coast of Trinidad, greater bulldog bats have learnt how to fish. Their echolocation is so sensitive, they can detect the faintest of clues. Just a fish’s fin breaking the surface is all they need to start fishing, with spectacular results. Echolocation has enabled bats to truly master the night. Today, more than one quarter of all mammal species are bats. And that’s not all. They also form the greatest gatherings of mammals on Earth. In the heart of Austin, Texas, every evening in August, crowds gather at Congress Avenue Bridge to witness one of life’s greatest spectacles, as one and a half million bats flood out from this daytime roost in the heart of the city. For many mammals, this journey into the night is far from over. Today, some mammals are shifting back to the night, just as they did two hundred million years ago, to avoid competition with daytime dinosaurs. But today, they are doing it to avoid the modern equivalent – us. In recent years, one of America’s most successful predators, the coyote, has taken the night shift, enabling it to move into the heart of some of America’s busiest and biggest cities. Chicago is now home to 4,000 coyotes, and they surprisingly haven’t moved in to live on trash. In the city’s downtown parks, they have found a wealth of wild prey, hunting whilst the city sleeps. Series 1: 2. The New Wild For millions of years, mammals have evolved to master every environment on Earth, but the planet is changing rapidly, all thanks to one mammal in particular - humans. As mankind reshapes the face of the world, mammals must change with it if they are to survive, let alone thrive. Today, some are finding clever and surprising ways to make the most of this new wild, while others need a helping hand from us. In the busy fish markets of Chile, sea lions have found an easy meal, but not everyone is so tolerant of these new neighbours. Living on the urban edge has brought them into fierce conflict with stray dogs, which makes life here a dangerous undertaking. The waterways of Singapore make an ideal home for otters. Here, its most daring family has learnt to cross busy highways amongst the bustling heart of the city. But daily road crossings mean that some struggle to keep up and get left behind, making it difficult to reunite with their family amongst the crowded city. For some mammals it can be harder to fit in to the new wild. Elephants have learnt to use the cover of darkness to venture into our towns in search of a midnight feast, often leaving destruction in their wake. As the human population grows, we need increasing amounts of space to grow food. The palm oil plantations of south east Asia seem devoid of life, but they harbour a new and surprising opportunity for a troop of resourceful pig-tailed macaques. Though many mammals have learnt to adapt to our changing world, for others the new pressures can be more challenging. With water from river systems being diverted for agriculture, in Tanzania, hippos are forced to compete fiercely for space in the few remaining water holes, or risk being left out in the open and stranded in the heat. For Indian wolves, their keen sense of smell enables them to seek refuge in the only place humans don’t dare go – the abandoned minefields left over from a war between Israel and Syria. Protected by the deadly mines, this unusual sanctuary has enabled the wolves a safe place to rear their young. American buffalo or bison were driven to near extinction by hunting, but following part domestication, vast managed herds fill their ancestral plains once again. Balance is critical in today’s new wild, and space is vital to protect wildlife. African parks and reserves have created essential space for the cheetah, but in some places, the wilderness is becoming overcrowded, and sometimes at a deadly cost. In areas of high tourism, the chance of cheetah cub survival is severely reduced. In order to survive, some of the world’s most iconic mammals need support. The blue whale has cruised the ocean for millions of years, but today’s ocean is a bustling highway, with tens of thousands of cargo ships in operation around the globe. Collisions pose a serious threat to the population, but scientists have been gathering valuable data in order to help not just the biggest mammal of all, but the biggest animal to have ever lived - the blue whale. The more we learn, the better we can find a balance and share our rapidly changing planet with our fellow mammals. Series 1: 3. Water Water presents air-breathing mammals with some of the greatest challenges of any environment on Earth. Less than 2% of mammal species are considered truly marine mammals. Those that have evolved to live in water have become some of the most specialised of all. They are characterised by their intelligence and ingenuity, forming groups that cooperate and communicate, and that are able to take advantage of the incredible opportunities found at sea. In this episode, we witness some of the most intimate and surprising behaviours of marine mammals. Raising the bar on our understanding of how whales and dolphins make their lives at sea, as well as meeting those terrestrial mammals that dip their toes, and sometimes more, into the watery world. In a journey from inland freshwater pools, where monkeys take the plunge in search of a seasonal delight, to the mysterious deep open ocean, where the largest toothed predator on earth, the sperm whale, dives deep into the cold, dark depths, and far beyond that of nearly all other air-breathing animals. In a rare glimpse into this world, we follow it in its pursuit of prey, filmed in an astonishing moment by a specially designed on-board camera, able to withstand the crushing pressures experienced by the whale at these incredible depths. Back at the surface, we witness incredible new behaviour: from the birth of a huge sperm whale calf, to orca hunting behaviour never before filmed, cementing their title as one of the greatest predators on earth. This sequence pits the naïveté and trust of a young humpback coming up against the brilliance of remarkable and calculating killers for the first time. Off the coast of New Zealand, we see mammal species working together as a team, with false killer whales and bottlenose dolphins hunting in unison. But it’s not as simple as it may seem, as the false killer whales are in reality setting an elaborate trap, and in a surprisingly tender moment, they share their food with other false killers to ensure even those unable to make a catch can feed. Nearer shore we see a dolphin mother overcome the problems of hunting in the warm shallow waters of Florida Bay, creating rings of muddy water in order to catch fish and feed her family. But only a few mammals like dolphins and whales have completely lost all their ties with land. Many, like Galapagos sea lions, have to return to the shore to give birth. Others, like the unique and bizarre star-nosed mole, with its highly sensitive nose and paddle-like feet, have successfully managed to straddle the world of land and water, hunting both underground and underwater. In Mexico, coastal coyotes have learnt they can benefit from the daily offerings washed up on the shore with each new tide, helping them to not just survive, but thrive, on the harsh fringes between the barren desert and fertile Pacific Ocean. Series 1: 4. Cold Having honed their survival strategies over millennia, mammals have evolved to be masters of the cold. In this episode, we journey across the globe, exploring a frozen world, from icy seas to snow-capped mountains and meet the unique mammals that call them home. For most, the cold is a killer. But for mammals, with their unique physical traits like warm thick fur and rich nourishing milk, and remarkable behaviours like hibernation, conquering the cold is possible. We begin our journey on the Arctic islands of Svalbard, where polar bears, synonymous with this cold archipelago, dominate this remote frozen world. But as their world warms, and the frozen seas that are their hunting grounds disappear, they are being forced to find new sources of food. For the first time, we follow a polar bear hunting on land as it heads high up into the mountains in a rarely seen long-distance pursuit of Svalbard’s reindeer. Mammals have been forced to adapt to the cold for millions of years. Whereas other species avoided the series of thick ice sheets that once covered a quarter of all land, mammals were able to survive the freezing conditions, and by adapting their behaviour, many are now completely at home in these inhospitable lands. One land that has little changed since the last ice age is the tundra of northern Alaska. In this remote, hostile landscape, a mythical and rarely seen mammal endures: the wolverine. They rely completely on snow to survive, providing them meat from animals that have succumbed to the cold and dens in which to raise their young. Whilst other animals either flee or hibernate to avoid the coldest time of year, they stay active all winter, traversing the vast landscape in search of food. This privileged view reveals a surprisingly caring side of a highly elusive animal. Knowledge can play a huge role in surviving the cold. Rather than roaming huge distances, some smart mammals will return annually to places they know will provide them with food. In Canada’s northern Yukon, a unique community of bears has been passing knowledge down the generations of a special ice-free river. While most bears are already hibernating, this late flowing river allows chum salmon to spawn into the winter months, giving the bears an opportunity for one last feast before hibernation that they simply cannot resist. Mammals’ ability to hibernate is a clever way to avoid winter, and deep underground in an abandoned mine, little and big brown bats are well into their hibernation. But not all stay asleep. One sneaky bat wakes in order to mate while the rest of the colony sleeps on. Bringing newborns into a world of snow and ice has many challenges, but mammals’ unique ability to produce fat-rich milk allows harp seal mothers to have one of the shortest weening periods of all. In just 12 days, off the coast of Greenland, they race to fatten their pups to independence as the icy nursery melts around them. Far above sea level, the remote Kluane Mountains of North America support the largest ice field outside the poles. In this rugged landscape of rock and ice, pika, a relative of the rabbit, patiently wait for summer. Having stayed awake all winter, surviving on food they collected last year, once summer does return, they will all have just a few weeks to harvest nearly a year's worth of food before the winter lockdown begins again. But storing your hard-earnt supplies all in one place comes at a risk if you can’t trust your neighbour. Averaging 4,000 meters above sea level, the thin air of the lofty mountains of the Qinghai-Tibet Plateau in China struggle to retain much heat at all. As a result, life here always feels cold. Snow leopards are the top predator and have lived here for millions of years, but recently their lives have become linked with humans and the domestic yak they herd. It’s too good an opportunity to ignore. But through a community initiative, they have found a way to live alongside each other, even when the yak are taken by the leopards. Back at sea level, on the shores of Canada’s Hudson Bay, for mammals specialised for life in the cold, a warming world is now the biggest challenge. Here, arctic fox and polar bears wait together by open water where there should be ice. For arctic foxes living here, as food ashore runs out, they would normally move and follow the polar bears onto the ice in order to scavenge off the bears' kills. But as the winter freeze, and arrival of the ice is delayed, the bears cannot hunt, and life becomes more and more desperate. This has led to the foxes resorting to cannibalism, desperately fighting with each other to feed on the unfortunate foxes that have succumbed to hunger. Series 1: 5. Heat By pushing themselves and their bodies to the absolute limit, mammals have found remarkable ways to survive in the hottest places on earth. From baking deserts, harsh dry spiny forests, barren desolate salt pans and even raging bush fires, mammals, with their remarkable intelligence, unique behaviours and incredible adaptations, have found ways to beat the heat. In South America, a family of capuchins live high on the sun-baked cliffs in Brazil’s driest region, the Serra da Capivara. But as the heat rises, they must descend from the cliffs and go in search of water on the forest floor. Finding it requires them to use all their natural curiosity and intelligence if they are to solve a real monkey puzzle and reach water. Arabian camels roam Australia’s vast, scorching, desert outback. Originally introduced by humans for use as pack animals and then released into the wild when no longer needed, around a million now wander the outback. With their distinctive hump acting as an energy store, they can go for days, even weeks without water. One male, on a quest to find a female, must rely on his bizarre dulla, a sac he inflates out the side of his mouth, to hopefully impress! Will his advances prove successful? A group of white sifaka lemurs in Madagascar’s spiny forest have found an unusual way to keep cool. In the heat of the day, they traverse the forest with their distinctive hopping motion in search of a special tree and when they find it – they hug it! Cool water drawn up from below by the tree roots means the cooler trunk offers some respite from the burning heat. A behaviour only recently recorded but expected to be seen more as global temperatures rise. The bizarre echidna has its own special way to stay cool – it blows snot bubbles. But to avoid the most destructive heat of all – fire – it does something far more extreme. Forced underground by advancing flames, they go into a deep sleep known as a torpor, allowing them to sleep for days at a time through the worst conditions, only emerging when it is safe. But as climates change and bushfires increase in frequency, will this behaviour be enough to survive into the future? In Arizona’s Sonoran Desert, the tiny but tough Harris’s antelope squirrel can come out during the heat of the day thanks to its amazing ability to let its body temperature rise above that of most other mammals and then 'heat dump' to quickly cool down. To do this, it ‘belly flops’, pressing its body against cool sand to lose heat and then carry on feeding whilst most other mammals have had to seek shelter to avoid the heat. In the stunning Hoanib in Namibia, a group of the world’s tallest mammal, the giraffe, graze on what little foliage they can find. To help, their tongues are coloured black to protect them from sunburn. But the dominant male has to defend his herd against an approaching rival and fight in the midday sun. Thermal imagery reveals their spotted pattern is actually part of an elaborate air-conditioning system designed to help them keep cool even in the heat of battle. In Trinidad, the white-winged vampire bat uses heat to help it live its bloodthirsty lifestyle. Highly sensitive cells in its nose can detect the heat from its prey’s blood just beneath the skin, allowing it to bite the perfect spot and get a meal. A troop of baboons on the banks of the Nile in Uganda also use heat to their advantage. While the baboons wait in the shade, a female crocodile guarding its nest full of eggs has to stay out in the open. Eventually, the heat is too much, and the crocodile must return to the river to cool down, giving the baboons the opportunity they’ve been patiently waiting for – a meal of tasty eggs. But not until the baboons have let others do their dirty work and dig out the eggs for them. One of the toughest places to find food is in the vast, hot and hostile Etosha salt pan of Namibia. Here, a mother jackal makes her way to one of the few waterholes in search of a meal. Her smash-and-grab attempt to catch a guinea fowl doesn’t work, so instead she must change her tactics and use all her mammalian cunning to hunt down a flock of doves as they drink. Series 1: 6. Forest Sir David Attenborough reveals why forests are the ultimate test of survival for mammals and how they have overcome the challenges of life in this multidimensional, complex and continually changing environment. We rise up against the pull of gravity, travelling through the many layers of a forest, from the ground dwellers and their secret communications to the resourceful honey hunters and tenacious tree climbers, before heading into the skies above to witness the largest gathering of mammals on earth. This episode features one of nature’s most iconic predatory mammals: the tiger. We meet a young tigress with one of the richest territories in India. Yet, with the heat of Indian summer, the odds are turned. Even with her iconic black and orange camouflage, her stealth and hunting strategies are put to the test. Mammalian intelligence helps her find an alternative strategy to succeed. On the forest floor of Madagascar, the tiny tenrec has a remarkable way of keeping in touch. On its back is a patch of stiff bristles it can rub together and send a secret message to the rest of its family as they feed amongst the undergrowth. In the cold, damp forests of North America, a solitary bobcat has learned to use the many fallen logs that criss-cross the forest floor to help it hunt for a seasonal treat – spawning salmon. But lacking the thick waterproof coat and webbed feet of its neighbouring otters, it has to take a more cautious approach to catch its slippery supper. In Africa, we feature our closest wild relatives – chimpanzees. With their knowledge and understanding of the jungle, they are able to find food where at first there appears to be none. But the young chimps lack the experience of their wise elders, who know how to avoid getting stung when searching for a real forest treat – honey. The troop, nonetheless, needs to work together to gain a more substantial meal – a red-capped mangabey monkey. Using their supreme strength and agility, they climb into the trees, where they set a cunning and tactical ambush for their unsuspecting prey. The mantled howler monkeys of Costa Rica are amongst the loudest land animals on earth, and their call can be heard for miles throughout the forest. They live almost their entire lives at the top of the canopy, using their prehensile tail as a fifth limb to help them travel safely from tree to tree, rarely, if ever, coming to ground. But today, the troop faces a new challenge. As their forest habitat disappears, the alpha male must lead his family from one part of the forest to another, passing through a town on a perilous journey travelling along its electricity cables, where every step is now a deadly gamble. Not all mammals are natural tree climbers, but in Uganda, a remarkable pride of lions has learned to make the most of its changing world. As temperatures rise, cactus-like euphorbia trees are spreading, and lions have discovered that not only is it cooler up in these spiny trees, but that they also make excellent watch towers from which to spot their prey. In the snowy forests of the north, one mammal is perfectly at ease in the trees, gliding elegantly and effortlessly from one to another in search of food – the Siberian flying squirrel. But the only mammals to have truly mastered flight are the bats. In Zambia, we witness one of the planet’s greatest wildlife spectacles and the largest gathering of mammals seen anywhere on earth. From one small patch of forest, up to ten million fruit bats take to the air in search of ripening fruit in the surrounding forests. In the short space of time the bats are here, they will disperse over a billion seeds, helping to regenerate the forest. But today, this intricate balance between the bats and many other mammals that rely on forests is under threat, all due to the actions of the most successful mammal of all – us. -- General Unique ID : 177839748433310459753546830981470996814 (0x85CAB08EEF1E17011CE1432546C5C94E) Complete name : Mammals - 1x01 - Dark.mkv Format : Matroska Format version : Version 4 File size : 2.42 GiB Duration : 59 min 2 s Overall bit rate : 5 864 kb/s Frame rate : 50.000 FPS Encoded date : 2025-01-08 19:30:59 UTC Writing application : mkvmerge v89.0 ('And the Melody Still Lingers On (Night in Tunisia)') 64-bit Writing library : libebml v1.4.5 + libmatroska v1.7.1 / Lavf61.7.100 Video ID : 1 Format : HEVC Format/Info : High Efficiency Video Coding Format profile : Main [email protected]@High Codec ID : V_MPEGH/ISO/HEVC Duration : 59 min 2 s Bit rate : 5 601 kb/s Width : 3 840 pixels Height : 2 160 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 50.000 FPS Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 10 bits Bits/(Pixel*Frame) : 0.014 Stream size : 2.31 GiB (96%) Default : Yes Forced : No Color range : Limited Color primaries : BT.2020 Transfer characteristics : HLG Matrix coefficients : BT.2020 non-constant Audio ID : 2 Format : AAC LC Format/Info : Advanced Audio Codec Low Complexity Codec ID : A_AAC-2 Duration : 59 min 2 s Bit rate : 259 kb/s Channel(s) : 2 channels Channel layout : L R Sampling rate : 48.0 kHz Frame rate : 46.875 FPS (1024 SPF) Compression mode : Lossy Stream size : 109 MiB (4%) Title : Stereo Language : English Default : Yes Forced : No Text ID : 3 Format : UTF-8 Codec ID : S_TEXT/UTF8 Codec ID/Info : UTF-8 Plain Text Duration : 58 min 17 s Bit rate : 104 b/s Frame rate : 0.180 FPS Count of elements : 630 Stream size : 44.7 KiB (0%) Default : Yes Forced : No
