Avian Flight covers all the main aspects of aerial locomotion by birds including sections on the history of thinking about bird flight, aerodynamics, functional morphology, evolution, kinematics, physiology, energetics and the cost of flight. The subject is complex and still not yet fully understood, and the author argues a convincing case for rethinking or even abandoning some of the old, well-established concepts.

An action-packed archaeological adventure from global bestseller Wilbur Smith “You should know of the legend. At a time when the rocks were soft and the air was misty, there was an abomination and an evil in this place which was put down by our ancestors. They placed a death curse upon these hills and commanded that this evil be cleaned from the earth and from the minds of men, forever.” A lost civilisation. A curse reborn. Dr Ben Kazin has only a blurred photograph and a gut instinct that there is a lost city to uncover somewhere beneath the Botswana cliffs. Soon, a whispered curse and a chance encounter with a local tribe lead him to discover much more than city foundations. The curse, it seems, is real, and will link Ben, his oldest friend, and the woman they both love with a forgotten leader from two thousand years ago, in a city of glory and honour that subsequently disappeared without a trace. But what happened to that ancient civilisation? And what is it that connects that lost empire to Ben, and the violent dangers he must face in the present day?

Sunbirds is the first book since the 19th Century to cover in detail all the world's sunbirds and spiderhunters - the Nectarinidae. It also includes the allied families of flowerpeckers and sugarbirds; a total of 176 species is described and illustrated. The book has been designed to help readers identify all of these species and also their various subspecies, the most distinctive of which are illustrated as well as described. Each species account provides a distribution map, a summary of identification criteria and a description of how the species differs from similar ones. The calls and songs, habitat, geographical distribution, status, movements, food (including a list of known food plants), habits, and breeding biology are also described. Finally, a full description of the species and salient features of each subspecies is given, together with measurements and references. Sunbirds not only aids identification, it provides a wealth of information on the ecology and behaviour of these birds. The authors have carried out extensive fieldwork in Asia and Africa. They have also studied skins, nests and eggs held by museums, analysed tape recordings and critically reviewed the vast amount of material contained in books and scientific journals. The superb plates would not have been possible without the exhaustive study of specimens which, together with the use of photographs of living birds, has resulted in the artist, Richard Allen, capturing the essence of the birds, their 'jizz', and accurately portraying the beautiful, bright, often iridescent, plumages of these spectacular families.

“The first time we came here I didn’t know what to expect,” she told me as we paddled upstream. “What we found just blew me away. Jaguars, pumas, river otters, howler monkeys. The place was like a Noah’s Ark for all the endangered species driven out of the rest of Central America. There was so much life! That expedition was when I first saw the macaws.” As a young woman, Sharon Matola lived many lives. She was a mushroom expert, an Air Force survival specialist, and an Iowa housewife. She hopped freight trains for fun and starred as a tiger tamer in a traveling Mexican circus. Finally she found her one true calling: caring for orphaned animals at her own zoo in the Central American country of Belize. Beloved as “the Zoo Lady” in her adopted land, Matola became one of Central America’s greatest wildlife defenders. And when powerful outside forces conspired with the local government to build a dam that would flood the nesting ground of the last scarlet macaws in Belize, Sharon Matola was drawn into the fight of her life. In The Last Flight of the Scarlet Macaw, award-winning author Bruce Barcott chronicles Sharon Matola’s inspiring crusade to stop a multinational corporation in its tracks. Ferocious in her passion, she and her confederates–a ragtag army of courageous locals and eccentric expatriates–endure slander and reprisals and take the fight to the courtroom and the boardroom, from local village streets to protests around the world. As the dramatic story unfolds, Barcott addresses the realities of economic survival in Third World countries, explores the tension between environmental conservation and human development, and puts a human face on the battle over globalization. In this marvelous and spirited book, Barcott shows us how one unwavering woman risked her life to save the most beautiful bird in the world. "Barcott’s compelling narrative is suspenseful right up to the last moment." –Publisher's Weekly "An engrossing but sad account of a brave and quirky champion of nature."–Kirkus “…A riveting account of one woman’s fight to save one of the last bastions of an endangered Species. . . Barcott writes of international politics, ecology and endangered species, and human relations with equal facility. This real page-turner of narrative nonfiction is hard to put down.” –Booklist

Shortlisted for the Readings Prize for New Australian Fiction in 2019! The Flight of Birds is a novel in twelve stories, each of them compelled by an encounter between the human and animal worlds. The birds in these stories inhabit the same space as humans, but they are also apart, gliding above us. The Flight of Birds: A Novel in Twelve Stories explores what happens when the two worlds meet. Joshua Lobb’s stories are at once intimate and expansive, grounded in an exquisite sense of place. The birds in these stories are variously free and wild, native and exotic, friendly and hostile. Humans see some of them as pets, some of them as pests, and some of them as food. Through a series of encounters between birds and humans, the book unfolds as a meditation on grief and loss, isolation and depression, and the momentary connections that sustain us through them. Underpinning these interactions is an awareness of climate change, of the violence we do to the living beings around us, and of the possibility of transformation. The Flight of Birds will change how you think about the planet and humanity’s place in it.

Do we have an adequate understanding of fluid dynamics phenomena in nature and evolution, and what physical models do we need? What can we learn from nature to stimulate innovations in thinking as well as in engineering applications? Concentrating on flight and propulsion, this unique and accessible book compares fluid dynamics solutions in nature with those in engineering. The respected international contributors present up-to-date research in an easy to understand manner, giving common viewpoints from fields such as zoology, engineering, biology, fluid mechanics and physics. Contents: Introduction to Fluid Dynamics; Swimming and Flying in Nature; Generation of Forces in Fluids - Current Understanding; The Finite, Natural Vortex in Steady and Unsteady Fluid Dynamics - New Modelling; Applications in Engineering with Inspirations From Nature; Modern Experimental and Numerical Methods in Fluid Dynamics.

Approaches the subject from a biological and evolutionary perspective rather than just identification.
