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.

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.

For those who could read between the lines, the censored news out of China was terrifying. But the president insisted there was nothing to worry about. Fortunately, we are still a nation of skeptics. Fortunately, there are those among us who study pandemics and are willing to look unflinchingly at worst-case scenarios.
Michael Lewis’s taut and brilliant nonfiction thriller pits a band of medical visionaries against the wall of ignorance that was the official response of the Trump administration to the outbreak of COVID-19. The characters you will meet in these pages are as fascinating as they are unexpected.
A thirteen-year-old girl’s science project on transmission of an airborne pathogen develops into a very grown-up model of disease control. A local public-health officer uses her worm’s-eye view to see what the CDC misses, and reveals great truths about American society. A secret team of dissenting doctors, nicknamed the Wolverines, has everything necessary to fight the pandemic: brilliant backgrounds, world-class labs, prior experience with the pandemic scares of bird flu and swine flu…everything, that is, except official permission to implement their work.
Michael Lewis is not shy about calling these people heroes for their refusal to follow directives that they know to be based on misinformation and bad science. Even the internet, as crucial as it is to their exchange of ideas, poses a risk to them. They never know for sure who else might be listening in.
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...
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, have sex, 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.
The scuba-diving philosopher and bestselling author of Other Minds explores the origins of animal consciousness. Dip below the ocean's surface and you are soon confronted by forms of life that could not seem more foreign to our own: sea sponges, soft corals and flower-like worms, whose rooted bodies and intricate geometry are more reminiscent of plant life than anything recognisably animal. Yet these creatures are our cousins. As fellow members of the animal kingdom - the Metazoa - they can teach us about the evolutionary origins of not only our bodies, but also our minds. In his acclaimed book, Other Minds, Peter Godfrey-Smith explored the mind of the octopus - the closest thing to an intelligent alien on Earth. In Metazoa, he expands his inquiry to animals at large, investigating the evolution of experience with the assistance of far-flung species. Godfrey-Smith shows that the appearance of the first animal body form well over half a billion years ago was a profound innovation that set life upon a new path. He charts the ways that subsequent evolutionary developments - eyes that track, for example, and bodies that move through and manipulate the environment - shaped the lives of animals. Following the evolutionary paths of a glass sponge, soft coral, banded shrimp, octopus and fish, then moving onto land and the world of insects, birds and primates like ourselves, Metazoa gathers these stories together to bridge the gap between matter and mind and address one of the most important philosophical questions: what is the origin of consciousness? Combining vivid animal encounters with philosophy and biology, Metazoa reveals the impossibility of separating the evolution of our minds from the evolution of animals themselves.
