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
For hundreds of thousands of years, Great Auks thrived. And then they were gone ... For hundreds of thousands of years Great Auks thrived in the icy seas of the North Atlantic, bobbing on the waves, diving for fish and struggling up onto rocky shores to mate and hatch their fluffy chicks. But by 1844, not a single one of these magnificent birds was alive. In this stunningly illustrated non-fiction picture book, award-winning author and illustrator Jan Thornhill tells the tragic story of these birds that “weighed as much as a sack of potatoes and stood as tall as a preteen’s waist.” Their demise came about in part because of their anatomy. They could swim swiftly underwater, but their small wings meant they couldn’t fly and their feet were so far back on their bodies, they couldn’t walk very well. Still the birds managed to escape their predators much of the time ... until humans became seafarers. Great Auks were pursued first by Vikings, then by Inuit, Beothuk and finally European hunters. Their numbers rapidly dwindled. They became collectors’ items — their skins were stuffed for museums, to be displayed along with their beautiful eggs. (There are some amazing stories about these stuffed auks — one was stolen from a German museum during WWII by Russian soldiers; another was flown to Iceland and given a red-carpet welcome at the airport.) Although undeniably tragic, the final demise of the Great Auk led to the birth of the conservation movement. Laws were eventually passed to prevent the killing of birds during the nesting season, and similar laws were later extended to other wildlife species.

Book Description
This is the first book to summarize the methods, conceptual issues and results of studies using the interpretation of feather growth rates as an index of nutritional condition in birds. The author has coined the term ptilochronology (literally, 'the study of feather time') to describe this technique, which relies on the fact that as a feather grows it produces visible growth bars. Both the technique and its conceptual foundations have been applied worldwide to numerous studies ofavian evolution, ecology, and conservation biology. The author reviews this work, chronicles the various criticisms that have been made, and describes how these have influenced the development of ptilochronology. He goes on to suggest experimental methodologies and analytical techniques to safeguardagainst invalid results. A final chapter summarises this new technique's contribution to avian biology, and suggests potential applications and a future research agenda. An appendix details specific measurements and describes the methodology associated with ptilochronology.Ptilochronology provides a practical resource as well as a conceptual understanding of how this technique can be used to address important questions in avian biology. It will be of relevance and use to professional avian biologists and ornithologists as well as to graduate students of avian behavioural ecology, evolution and conservation.
