Book Description
When and where did the ancestors of modern birds evolve? What enabled them to survive the meteoric impact that wiped out the dinosaurs? How did these early birds spread across the globe and give rise to the 10,600-plus species we recognise today ― from the largest ratites to the smallest hummingbirds? Based on the latest scientific discoveries and enriched by personal observations, The Ascent of Birds sets out to answer these fundamental questions. The Ascent of Birds is divided into self-contained chapters, or stories, that collectively encompass the evolution of modern birds from their origins in Gondwana, over 100 million years ago, to the present day. The stories are arranged in chronological order, from tinamous to tanagers, and describe the many dispersal and speciation events that underpin the world's 10,600-plus species. Although each chapter is spearheaded by a named bird and focuses on a specific evolutionary mechanism, the narrative will often explore the relevance of such events and processes to evolution in general. The book starts with The Tinamou’s Story, which explains the presence of flightless birds in South America, Africa, and Australasia, and dispels the cherished role of continental drift as an explanation for their biogeography. It also introduces the concept of neoteny, an evolutionary trick that enabled dinosaurs to become birds and humans to conquer the planet. The Vegavis's Story explores the evidence for a Cretaceous origin of modern birds and why they were able to survive the asteroid collision that saw the demise not only of dinosaurs but of up to three-quarters of all species. The Duck's Story switches to sex: why have so few species retained the ancestral copulatory organ? Or, put another way, why do most birds exhibit the paradoxical phenomenon of penis loss, despite all species requiring internal fertilisation? The Hoatzin's Story reveals unexpected oceanic rafting from Africa to South America: a stranger-than-fiction means of dispersal that is now thought to account for the presence of other South American vertebrates, including geckos and monkeys. The latest theories underpinning speciation are also explored. The Manakin’s Story, for example, reveals how South America’s extraordinarily rich avifauna has been shaped by past geological, oceanographic and climatic changes, while The Storm-Petrel’s Story examines how species can evolve from an ancestral population despite inhabiting the same geographical area. The thorny issue of what constitutes a species is discussed in The Albatross's Story, while The Penguin’s Story explores the effects of environment on phenotype ― in the case of the Emperor penguin, the harshest on the planet. Recent genomic advances have given scientists novel approaches to explore the distant past and have revealed many unexpected journeys, including the unique overland dispersal of an early suboscine from Asia to South America (The Sapayoa’s Story) and the blackbird's ancestral sweepstake dispersals across the Atlantic (The Thrush’s Story). Additional vignettes update more familiar concepts that encourage speciation: sexual selection (The Bird-of-Paradise's Story); extended phenotypes (The Bowerbird's Story); hybridisation (The Sparrow's Story); and 'great speciators' (The White-eye's Story). Finally, the book explores the raft of recent publications that help explain the evolution of cognitive skills (The Crow's Story); plumage colouration (The Starling's Story); and birdsong (The Finch's Story)

Book Description
The average person can name more bird species than they think, but do we really know what a bird “species” is? This open access book takes up several fascinating aspects of bird life to elucidate this basic concept in biology. From genetic and physiological basics to the phenomena of bird song and bird migration, it analyzes various interactions of birds – with their environment and other birds. Lastly, it shows imminent threats to birds in the Anthropocene, the era of global human impact. Although it seemed to be easy to define bird species, the advent of modern methods has challenged species definition and led to a multidisciplinary approach to classifying birds. One outstanding new toolbox comes with the more and more reasonably priced acquisition of whole-genome sequences that allow causative analyses of how bird species diversify. Speciation has reached a final stage when daughter species are reproductively isolated, but this stage is not easily detectable from the phenotype we observe. Culturally transmitted traits such as bird song seem to speed up speciation processes, while another behavioral trait, migration, helps birds to find food resources, and also coincides with higher chances of reaching new, inhabitable areas. In general, distribution is a major key to understanding speciation in birds. Examples of ecological speciation can be found in birds, and the constant interaction of birds with their biotic environment also contributes to evolutionary changes. In the Anthropocene, birds are confronted with rapid changes that are highly threatening for some species. Climate change forces birds to move their ranges, but may also disrupt well-established interactions between climate, vegetation, and food sources. This book brings together various disciplines involved in observing bird species come into existence, modify, and vanish. It is a rich resource for bird enthusiasts who want to understand various processes at the cutting edge of current research in more detail. At the same time it offers students the opportunity to see primarily unconnected, but booming big-data approaches such as genomics and biogeography meet in a topic of broad interest. Lastly, the book enables conservationists to better understand the uncertainties surrounding “species” as entities of protection.

Book Description
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. An account of the Cenozoic fossil record sheds light on the biogeographic history of the extant avian groups and discusses fossils in the context of current phylogenetic hypotheses. This review of the evolutionary history of birds not only addresses students and established researchers, but it may also be a useful source of information for anyone else with an interest in the evolution of birds and a moderate background in biology and geology.

Book Description
We all have our off days. Why should Evolution be any different? Maybe Evolution got carried away with an idea that was just a little too crazy—like having the Regal Horned Lizard defend itself by shooting three-foot streams of blood from its eyes. Or maybe Evolution ran out of steam (Memo to Evolution: The Irrawaddy Dolphin looks like a prototype that should have been left on the drawing board). Or maybe Evolution was feeling cheeky—a fish with hands? Joke’s on you, Red Handfish! Or maybe Evolution simply goofed up: How else to explain the overgrown teeth of the babirusas that curl backward over their face? Oops. Mara Grunbaum is a very smart, very funny science writer who celebrates the best—or, really, the worst—of Evolution’s blunders. Here are more than 100 outlandish mammals, reptiles, insects, fish, birds, and other creatures whose very existence leaves us shaking our heads and muttering WTF?! Ms. Grunbaum’s especially brilliant stroke is to personify Evolution as a well-meaning but somewhat oblivious experimenter whose conversations with a skeptical narrator are hilarious. For almost 4 billion years, Evolution has produced a nonstop parade of inflatable noses, bizarre genitalia, and seriously awkward necks. What a comedian!

Book Description
This authoritative handbook, part of the Helm Identification Guide series, looks in detail at the beautiful antpittas. Elusive study organisms for ornithologists and highly prized additions to the birder's life-list, the antpittas (Grallariidae) and gnateaters (Conopophagidae) are among the most poorly known Neotropical bird groups. This authoritative handbook is the first book dedicated solely to these two families, combining an exhaustive review of more than two centuries of literature with original observations by the author and many knowledgeable contributors. Antpittas and Gnateaters provides a thorough guide to the identification and ecology of these birds, with detailed maps accompanying the text. A series of superb plates illustrate most of the 156 recognized taxa; supplemented by more than 250 colour photographs, the immature plumages and natural history of many species are depicted for the first time. This book is the ultimate reference on these remarkable and beautiful birds, and an indispensable addition to the libraries of researchers and birders for many years to come.

Book Description
The moult strategies of birds are not only of importance in their impact on a species' ecology and energetics, but as a valuable tool for anyone studying the migration and population dynamics of bird species. A proper understanding of how feathers are replaced, and the precise differences in appearance of the various feather generations, can allow ringers, scientists and the keen birdwatcher to age first-year and adult birds and to detect the moult strategy of the bird in question. Lukas Jenni and Raffael Winkler have combined these themes and produced a book which will be valuable both to the professional ornithologist and the bird ringer. The first part gives an up to date summary of the moult strategies and moult sequences of European passerines and discusses the ecological consequences of moult. Throughout the book, the authors draw on the enormous amount of data on moult collected by them over 15 years of study which, combined with data from the literature, allow them to present a new synthesis of the subject. The second part of the book is of particular value to ringers. Following a general introduction to ageing, detailed moult profiles are given for 58 species of European passerines representing all the major moult strategies, backed up with useful summary statistics, schematic diagrams of the extent of moult and indications of the variation within each species. For the first time, the extent of partial and suspended moults is presented in detail. The crowning feature of this book is the 480 plus full colour photographs of extended wings which show the entire range of moult patterns and of plumage ageing criteria. An appendix gives supplementary information on ageing birds by the degree of pneumatization of the skull.
