This book is a totally fresh approach to observing birds in southern Africa. It affords you the opportunity to gather previously inaccessible and indecipherable information in the form of tracks and signs left behind by our avifauna. The book explores the unique details of the spoor, or tracks, of many species of birds. This is done in multiple ways including by observing their droppings, examining their feeding behaviour as well as their general nesting structures.

It’s remarkable how tracks and signs in nature help you to enrich your knowledge of bird species, providing knowledge as straightforward as the shape of the individual nests of our various species of weaver, or the ability to recognise and understand the role of a drum-site in the life of a bearded woodpecker, or even being able to see the subtle signs of a cardinal woodpecker on the various acacia pods which host its larval food.

Louis Liebenberg has generously provided some sketches of spoor he has made for his own publications, making these clear schematics available to assist with identification. Skulls, feathers, beaks and egg shells are also occasionally encountered, and a few examples of these will be included, as they also tell a story of a bird which has passed by. This approach to southern Africa’s birdlife will add tremendously to how we experience our wonderful avifauna.

A virologist's insight into how viruses evolve and why global epidemics are inevitable.

In 1993 a previously healthy young man was drowning in the middle of a desert, in fluids produced by his own lungs. This was the beginning of the terrifying Sin Nombre hantavirus epidemic and the start of a scientific journey that would forever change our understanding of what it means to be human. After witnessing the Sin Nombre outbreak, Dr Frank Ryan began researching viral evolution and was astonished to discover that it's inextricable from the evolution of all life on Earth. From AIDS and Ebola to the common cold, Ryan explores the role of the virus within every ecosystem on the planet.

His gripping conclusions shed new light on the natural world, proving that what doesn't kill you really does make you (and your species) stronger.

Break the rules, not the fast with world-renowned biohacker and New York Times bestselling author Dave Asprey.

For more than a decade, the Bulletproof founder Dave Asprey has shared his unique point of view and expertise to help fans become the best versions of themselves. From living longer to getting smarter, maximising performance to practising mindfulness, Dave's followers look to him for his take on the most effective techniques to become healthier and more powerful than most doctors think is possible. Asprey has been fasting for years, long before it gained widespread popularity, and if you're a fan of The Bulletproof Diet, you have been enjoying some of the benefits of Intermittent Fasting too.

In Fast This Way, Dave asks readers to forget everything they think they know about the ancient practice and takes them on a journey through cutting-edge science to examine the ways novice fasters and Intermittent Fasting loyalists can up-end their relationship with food and upgrade their fasting game beyond calorie restriction.

• What IF eating the right foods at the right time can actually enhance your fast?
• What IF how you work out and sleep could trick your body into thinking you are fasting?
• What IF it were easy to skip a meal, or two, or three?
• What IF fasting is different for women, can be personalised to your genes, and can impact your mental health?
• What IF all fasts could be created equal?

Fast This Way is a compelling read through the latest thinking on fasting and gives readers the manual and toolkit to make the most of their fasts and their personal biology.

A journey through the history and science of epidemics and pandemics – from measles to coronavirus.

For centuries mankind has waged war against the infections that, left untreated, would have the power to wipe out communities, or even entire populations. Yet for all our advanced scientific knowledge, only one human disease – smallpox – has ever been eradicated globally. In recent years, outbreaks of Ebola and Zika have provided vivid examples of how difficult it is to contain an infection once it strikes, and the panic that a rapidly spreading epidemic can ignite.

But while we chase the diseases we are already aware of, new ones are constantly emerging, like the coronavirus that spread across the world in 2020. At the same time, anti-microbial resistance is harnessing infections that we once knew how to control, enabling them to thrive once more.

Meera Senthilingam presents a timely look at humanity’s ongoing battle against infection, examining the successes and failures of the past, along with how we are confronting the challenges of today, and our chances of eradicating disease in the future.

Wat Moet Ons Met Ons Kerk Doen? is 'n poging om te probeer verstaan waar ons as Afrikaners teologies vandaan kom, watter kragte en magte ons en ons Kerk gevorm het en hoe ons Kerk tans daar uitsien.

Die N.G.Kerk was 'n belangrike en rigtinggewende rolspele in die opheffing van die Afrikaner na die Britse vergrype tydens en na die Tweede Vryheidsoorlog. Tans word die N.G.Kerk ervaar as 'n instansie wat ongevoelig teenoor die geestelike behoeftes van haar lidmate staan.

Hierdie is 'n moet-lees boek vir:

• Lidmate wat ons Kerk graag wil help om 'n gesonde, geestelike tuiste vir Suid-Afrikaners van die 21ste eeu te bied.
• Die klakkelose napraters van die dogma wat dink ons Kerk is steeds op die regte pad.
• Die plastiekpredikante van die radio en televisie wat met eentonige reëlmaat soetsappige, sogenaamd godsdienstige, pleisters plak.
• Diegene wat reeds ons Kerk tot die ashoop van die geloof verdoem het.

In this book, Adrian Koopman describes the complex relationship between birds, the Zulu language and Zulu culture. A number of chapters look at the underlying meaning of bird names, and here we will find that the Zulu name of the Goliath Heron means ‘what gives birth to baby crocodiles’, the dikkop (umbangaqhwa) means ‘what causes frost’, and the African Hoopoe is a party-goer who wears a colourful blanket.

The book goes further than just Zulu names, exploring the underlying meanings of bird names from other South African languages and languages from Central and East Africa. Here we find birds with names that translate as ‘cool-porridge’, ‘kiss-banana-flower’ and ‘waiter-at-the-end-of-the furrow’.

A focus on Zulu traditional oral literature details the roles birds have played in Zulu praise poetry (including the praise poems of certain birds themselves) and in proverbs, riddles and children’s games. Also considered is traditional bird lore, examining the role played by various species as omens and portents, as indicators of bad luck and evil, as forecasters of rain and storm, and as harbingers of the seasons. Here we see that the Bateleur Eagle (ingqungqulu) is linked to war, the Southern Ground Hornbill (insingizi) to thunder and heavy rain, the Red-chested Cuckoo (uphezukokhono) to the start of the ploughing season, and the Jacobin Cuckoo (inkanku) to the start of summer.

Zulu Bird Names and Bird Lore discusses the Zulu Bird Name Project, a series of Zulu bird name workshops held between 2013 and 2017 with Zulu-speaking bird guides designed to confirm (or otherwise) all previously recorded Zulu names for birds, while at the same time devising new names for those without previously recorded names. The result has been a list of species-specific names for all birds in the Zulu-speaking region. Finally, the book turns to the role such new bird names can play in conservation education and in avi-tourism.

See the world. Then make it better.

I am 93. I've had an extraordinary life. It's only now that I appreciate how extraordinary.

As a young man, I felt I was out there in the wild, experiencing the untouched natural world - but it was an illusion. The tragedy of our time has been happening all around us, barely noticeable from day to day -- the loss of our planet's wild places, its biodiversity. I have been witness to this decline. A Life on Our Planet is my witness statement, and my vision for the future. It is the story of how we came to make this, our greatest mistake -- and how, if we act now, we can yet put it right.

We have one final chance to create the perfect home for ourselves and restore the wonderful world we inherited. All we need is the will do so.

The humble and industrious dung beetle is a marvellous beast: the 6 000 species identified so far are intricately entwined with human history and scientific endeavour.

These night-soil collectors of the planet have been worshipped as gods, worn as jewellery, and painted by artists. More practically, they saved Hawaii from ecological blight, and rescued Australia from plagues of flies. They fertilise soil, cleanse pastures, steer by the stars, and have a unique relationship with the African elephant (along with many other ungulates). Above all, they are the ideal subject for biological study in an evolving world.

In this sweeping history of more than 3 000 years, beginning with Ancient Egypt, scientist Marcus Byrne and writer, Helen Lunn capture the diversity of dung beetles and their unique behaviour patterns. Dung beetles’ fortunes have followed the shifts from a world dominated by a religion that symbolically incorporated them into some of its key concepts of rebirth, to a world in which science has largely separated itself from religion and alchemy.

With over 6 000 species found throughout the world, these unassuming but remarkable creatures are fundamental to some of humanity’s most cherished beliefs and have been ever present in religion, art, literature, science and the environment. They are at the centre of current gene research, play an important role in keeping our planet healthy, and some nocturnal dung beetles have been found to navigate by the starry skies. Outlining the development of science from the point of view of the humble dung beetle is what makes this charming story of immense interest to general readers and entomologists alike. This entertaining outline of the development of science from the the beetle’s perspective will enchant general readers and entomologists alike.

WHEN we eat may be as important as WHAT we eat.

Like most people, you probably wake up, get hungry for meals and doze off in bed around the same time every day. If you’ve ever experienced jet lag or pulled an all-nighter, you know that this schedule can easily be thrown off kilter. But for some people, that imbalance—difficulty sleeping at night, hunger at odd times, or sudden fatigue at noon—is a constant. If you're one of those people, Dr. Satchin Panda, one of the leading researchers on circadian rhythms, has a plan to reset your body clock.

Beginning with an in-depth explanation of the circadian clock—why it’s important, how it works, and how to know it isn’t working—The Circadian Code outlines lifestyle changes to make to get back on track. It's a concrete plan to enhance weight loss, improve sleep, optimize exercise, and manage technology so that it doesn’t interfere with your body’s natural rhythm. Dr. Panda’s life changing methods show you how to prevent and reverse ailments like diabetes, cancer, and dementia, as well as microbiome conditions like acid reflux, heartburn, and irritable bowel disease.

Humanity has often found itself on the precipice. We've survived and thrived because we've never stopped moving...

In this eye-opening book, Johannes Krause, Chair of the Max Planck Institute for the History of Humanity, offers a new way of understanding our past, present and future.

Marshalling unique insights from archaeogenetics, an emerging new discipline that allows us to read our ancestors' DNA like journals chronicling personal stories of migration, Krause charts two millennia of adaption, movement and survival, culminating in the triumph of Homo Sapiens as we swept through Europe and beyond in successive waves of migration - developing everything from language, the patriarchy, disease, art and a love of pets as we did so.

We also meet our ancestors, from those many of us have heard of - such as Homo Erectus and the Neanderthals - to the wildly unfamiliar but no less real: the recently discovered Denisovans, who ranged across Asia and, like humans, interbred with Neanderthals; the Aurignacians, skilled artists who, 40,000 years ago, brought about an extraordinary transformation in what our species could invent and create; the Varna, who buried their loved ones with gold long before the Pharaohs of Egypt did; and the Gravettians, big game hunters who were Europe's most successful early settlers until they perished in the face of the toughest opponent humanity had ever faced: the ice age.

As well as being a radical new telling of our shared story, this book is a reminder that the global problems that keep us awake at night - climate catastrophe; the sudden emergence of deadly epidemics; refugee crises; ethnic conflict; over-population - are all things we've faced, and overcome, before.

Finally available in paperback, including the story from the Netflix documentary ‘My Octopus Teacher’ and many other remarkable creatures from the great African Sea Forest.

In this ground-breaking book, Dr Daniel Levitin uses cutting-edge research from neuroscience and psychology to demonstrate the importance of the stage that follows the middle-age. Packed with engaging interviews with successful, creative individuals far beyond the conventional age of 'retirement', this book also reflects on challenges many readers will recognize. Full of accessible and conversation-sparking takeaways, it demonstrates the importance of the distinct advantages and consequences of getting older. Levitin offers a realistic personal plan full of practical, cognitive enhancing tricks for everyone to follow as they age. Successful Ageing is a radical exploration of what we all can learn from those who age joyously, a new model for a positive elderly experience. This book will revolutionize the way we plan for old age as individuals, family members, and citizens of a society in which the average life expectancy continues to rise.

The Roberts Bird Guide (2nd Edition) has gone to great trouble to concentrate on, and illustrate, difficult-to-identify species and family groups such as raptors, warblers, cisticolas and waders. Special attention has been given to make sure there is far greater coverage of male-female differences and there are also many more juvenile illustrations. Unlike all previously published southern African bird guides, this new edition will be scattered with informative photographs that are incorporated in the text pages and each plate illustration is augmented with an introduction. Apart from the approximately 240 plate spreads, the guide also has 12 photographic and illustrated double spreads that show head enlargements and other details. Plates are annotated far more definitively than other guides – highlighting key identification features, especially for difficult-to-identify species.

Elephants are as unique as people. They can be clever and curious or headstrong and impulsive, shy or sociable. Learn to know them as individuals as well as a species in this evocative account of years spent studying elephant behaviour in the wild.

Watching a family out for a swim on a hot day, Dr Hannah Mumby notes grandmothers, mothers, sisters and children exchanging noisy greetings, a consistent stream of close-range vocalisations, intermittent touching, co-operative herding of babies and frequent stopping for snacks. A close and interconnected family. But in this family, the adults weigh several tons each and the babies wave trunks playfully at one another. This is a herd of elephants.

That elephants are intelligent, sentient beings is common knowledge, but so much about their day-to-day lives and abilities remains unknown. How do they communicate with one another over seemingly impossible distances? How do males spend their lives once they have left their mothers’ herds? And how much do they really remember?

In this lyrically written and deeply personal account of several years of field research, Mumby reverently describes her own elephant encounters, alongside an exploration of the most up-to-date discoveries about the lives of these gentle giants. Learn how elephants live, travel, mate, raise children and relate to one another, and reflect on how they think and feel. Understanding elephants as individuals closes the gap between human and animal and has powerful applications in the critical field of elephant conservation.

A Curious Garden of Herbs is a richly illustrated collection of herbal fact and lore that illuminates the "why" rather than the "how" of the historical kitchen garden. Rather than offering a how-to of gardening methods, Kay K. Moss and Suzanne S. Simmons trace herbs and their uses back to earlier times and places. A Curious Garden of Herbs is peppered with reflections and observations from manuscripts and published herbals that detail the historical uses and fascinating stories surrounding plants of documented interest in the early American South and mid-Atlantic. Practicality and necessity were the guiding theses for gardening in eighteenth- and early nineteenth-century rural and frontier settlements in the Southeast. There were plants for food, for seasoning, for medicine, for dye, for insect repellency, and for scent. While many of these plants were also decorative, utility dominated the rationale of backcountry gardeners. Unlike the experimental and exotic collections of Thomas Jefferson and other wealthy gentleman botanists, the gardens detailed in these pages are generally of the "middling sort"-of townspeople and farmers, of "housewives," merchants, and artisans. A Curious Garden of Herbs brings these everyday herbs to life with sixty historical illustrations. In addition to including the well-known varieties such as parsley, lavender, cucumber, and asparagus, this wonderfully illustrated catalog of more than a hundred plants also reveals new ways to enjoy violet, rose, and nasturtium. Moss and Simmons also encourage readers to invite lesser-known plants, such as wild purslane, mullein, and wood sorrel into their gardens and conversations.
