Its chemical properties, however, have long been known to be harmful to health, and research in the last 25 years has increasingly led wildlife researchers and health professionals to urge hunters to choose lead-free ammunition. This Fact Sheet is intended to explain their case the most essential facts are highlighted , and contains a sample of science citations supporting it. June Mixed-species groups of animals: behavior, community structure, and conservation by Eben Goodale, Guy Beauchamp, and Graeme D. Ruxton Call Number: Mixed-Species Groups of Animals: Behavior, Community Structure, and Conservation presents a comprehensive discussion on the mixed-species groups of animals, a spectacular and accessible example of the complexity of species interactions.
They are found in a wide range of animals, including invertebrates, fish, mammals and birds, and in different habitats, both terrestrial and aquatic, throughout the world. While there are more than articles on this subject scattered in separate categories of journals, there has yet to be a general, cross-taxa book-length introduction to this subject that summarizes the behavior and community structure of these groups.
The authors first survey the diversity of spatial associations among animals and then concentrate on moving groups. They review the major classes of theories that have been developed to explain their presence, particularly in how groups increase foraging efficiency and decrease predation.
Finally, they explore the intricacies of species interactions, such as communication, that explain species roles in groups and discuss what implications these social systems have for conservation. This is the ultimate flight-identification guide to Western Palearctic raptors. Based on this stunning photographic coverage, most of which has never been published before, this book represents a landmark in bird identification books and a major work for all raptor enthusiasts. This book is about a lifetime spent observing and photographing birds in Africa and internationally. The evocative text encapsulates a wide range of birdwatching experiences over a period of seventy years as the reader is taken along with the author on his fascinating quest for birds.
The account is enhanced by a wide selection of his photographs. These memories span a period of seventy years, initially in Cape Town, prior to living in Zimbabwe for seventeen years, before returning to settle in the shadow of my beloved Table Mountain. My time in Zimbabwe was the most productive period of my life in terms of ornithological research, especially on diurnal birds of prey and owls.
Seven chapters are devoted to these Zimbabwe years. Once back in Cape Town, there were opportunities for overseas travel, including several voyages on cruise ships as a guest lecturer. Dean Call Number: This book focuses on the activities of all the people who collected bird specimens in southern Africa, and their contribution to the science of southern African ornithology. In addition to the collectors, it covers some of the history and the development of ornithology as a science in southern Africa.
Dr Richard Dean draws particular attention to the fact that the southern African region is blessed with an exceptionally rich bird fauna involving over taxa. It is often difficult to identify closely related species in the field and this is why it has been so important to build up extensive collections of preserved bird skins and of eggs in natural history museums in various parts of the country and elsewhere in the world.
The book explains how the collectors of these specimens were active in selling or donating them to museums or they were collected by dedicated people with a passionate interest in the birds themselves. Particular attention was given to the period between and when museum collections were growing intensively, and were being used.

These bird collections have been used by several authors to provide material for books on birds during this period — E. Layard, A. Stark and W. Sclater, V. FitzSimons and E. Gill, to name a few.
A major user of bird collections in southern Africa was Austin Roberts, who compiled the first edition of the Birds of South Africa First Edition , extracting much of the original information for the descriptions from bird material that he had personally collected for the Transvaal Museum collection now Ditsong National Museum of Natural History.
Another major user of the bird collections was Dr P. Clancey, who used the collection at the Durban Natural Science Museum to describe and name a large number of subspecies of birds, as well as publishing books on birds. A field guide to the seabirds that occur around the southern African coastline.
Written by a specialist in the field of seabirds, the book focuses on the ID and behaviour of species of seabird commonly seen around the coast and in the seas of the region. The text is supported with photographs multiple images per bird where available and distribution maps for all species. The back cover pretty much says it all — over pages of detailed and original text.
Over colour photographs. Over stunning and accurate illustrations. Large format colour range maps based on latest geolocator and observational studies. Two DVDs with over minutes of highly informative footage with narration. To top this off there is a section after the species accounts that deals with confusion species and the features to concentrate on to sort them out. This is followed by four pages on how to separate the two should you be lucky enough to be called upon to do so.
The book is rounded off with a thirty-eight page ID jogger, which is a great way to test how much attention you were paying whilst reading the various sections of the book. Two DVDs accompany the guide and are in handy cases fixed to the inside front and back covers. Disc 1 covers the species accounts of all of the birds in the book, with videos and narration of the key features needed to tell them apart. Disc two looks at the families more broadly but also includes an identification quiz, to really make sure you have been taking notice.
Altogether a brilliant guide with a great approach to explaining how to make it a little easier to identify what can be very difficult birds indeed. The Princeton Guide to ecology by Simon A. Levin Call Number: The Princeton Guide to Ecology is a concise, authoritative one-volume reference to the field's major subjects and key concepts.
Edited by eminent ecologist Simon Levin, with contributions from an international team of leading ecologists, the book contains more than ninety clear, accurate, and up-to-date articles on the most important topics within seven major areas: autecology, population ecology, communities and ecosystems, landscapes and the biosphere, conservation biology, ecosystem services, and biosphere management. Complete with more than illustrations including sixteen pages in color , a glossary of key terms, a chronology of milestones in the field, suggestions for further reading on each topic, and an index, this is an essential volume for undergraduate and graduate students, research ecologists, scientists in related fields, policymakers, and anyone else with a serious interest in ecology.
The first ever Illustrated Checklist of the Birds of the World is really two works in one. It is a complete checklist whose taxonomy incorporates the most up-to-date information and an exhaustive methodology Tobias et al. At the same time, it contains illustrations and distribution maps for every bird species in the world.
February Flamingos: behavior, biology and relationship with humans by Anderson, Matthew J. Indeed, the much beloved flamingo is a popular attraction at zoos around the globe, and has become a cultural phenomenon as well, being displayed proudly on the lawns of many suburban homes as well as being featured prominently in works of literature and art.
Moreover, our unique relationship with and fascination for the charismatic flamingos are an interesting phenomena in their own rights. This edited volume is devoted to flamingo behavior, biology and their relationships with humans. By thoroughly exploring and considering each of these topics together in one volume, this work is designed to encourage in the reader a greater understanding of and appreciation for these fascinating and iconic birds. But while these avian enthusiasts have noted that birds eat fruit, carrion, and pests; spread seed and fertilizer; and pollinate plants, among other services, they have rarely asked what birds are worth in economic terms.
In Why Birds Matter, an international collection of ornithologists, botanists, ecologists, conservation biologists, and environmental economists seeks to quantify avian ecosystem services—the myriad benefits that birds provide to humans. The first book to approach ecosystem services from an ornithological perspective, Why Birds Matter asks what economic value we can ascribe to those services, if any, and how this value should inform conservation.
Chapters explore the role of birds in such important ecological dynamics as scavenging, nutrient cycling, food chains, and plant-animal interactions—all seen through the lens of human well-being—to show that quantifying avian ecosystem services is crucial when formulating contemporary conservation strategies. Both elucidating challenges and providing examples of specific ecosystem valuations and guidance for calculation, the contributors propose that in order to advance avian conservation, we need to appeal not only to hearts and minds, but also to wallets.
December Chamberlain's waders: the definitive guide to southern Africa's shorebirds by Faansie Peacock Call Number: This unique, lavishly illustrated book will help you not only to identify waders with confidence, but also to understand and enjoy these inspirational birds. What makes this book different from any other titles on waders?
An Ornithologist's Guide to Life, Stories by Ann Hood | | Booktopia
Firstly, it is written from a Southern Hemisphere perspective, unlike most European and American books. This shift of focus completely changes the picture! Secondly, it explains wader identification based on a background of biology and ecology — instead of just listing all the tedious identification details. Thirdly, it is so much more than just a field guide.
Some paragraphs really read like a love letter written to waders — in celebration of their beauty, adaptability and triumph over seemingly insurmountable challenges. November Avian evolution: the fossil record of birds and its paleobiological significance by Gerald Mayr Call Number: Knowledge of the evolutionary history of birds has much improved in recent decades. Fossils from critical time periods are being described at unprecedented rates and modern phylogenetic analyses have provided a framework for the interrelationships of the extant groups.
This book gives an overview of the avian fossil record and its paleobiological significance, and it is the only up-to-date textbook that covers both Mesozoic and more modern-type Cenozoic birds in some detail.
The reader is introduced to key features of basal avians and the morphological transformations that have occurred in the evolution towards modern birds.
