Book Description
For over one hundred years, ornithologists and amateur birders have jointly campaigned for the conservation of bird species, documenting not only birds’ beauty and extraordinary diversity, but also their importance to ecosystems worldwide. 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.

Book Description
How does a bird experience a city? A backyard? A park? As the world has become more urban, noisier from increased traffic, and brighter from streetlights and office buildings, it has also become more dangerous for countless species of birds. Warblers become disoriented by nighttime lights and collide with buildings. Ground-feeding sparrows fall prey to feral cats. Hawks and other birds-of-prey are sickened by rat poison. These name just a few of the myriad hazards. How do our cities need to change in order to reduce the threats, often created unintentionally, that have resulted in nearly three billion birds lost in North America alone since the 1970s? In The Bird-Friendly City, Timothy Beatley, a longtime advocate for intertwining the built and natural environments, takes readers on a global tour of cities that are reinventing the status quo with birds in mind. Efforts span a fascinating breadth of approaches: public education, urban planning and design, habitat restoration, architecture, art, civil disobedience, and more. Beatley shares empowering examples, including: advocates for “catios,” enclosed outdoor spaces that allow cats to enjoy backyards without being able to catch birds; a public relations campaign for vultures; and innovations in building design that balance aesthetics with preventing bird strikes. Through these changes and the others Beatley describes, it is possible to make our urban environments more welcoming to many bird species. Readers will come away motivated to implement and advocate for bird-friendly changes, with inspiring examples to draw from. Whether birds are migrating and need a temporary shelter or are taking up permanent residence in a backyard, when the environment is safer for birds, humans are happier as well.

Book Description
There are 10,500 species of bird worldwide and wherever they occur people marvel at their glorious colours and their beautiful songs. We also trap and consume birds of every kind. Yet birds have not just been good to eat. Their feathers, which keep us warm or adorn our costumes, give birds unique mastery over the heavens. Throughout history their flight has inspired the human imagination so that birds are embedded in our religions, folklore, music and arts. Vast in both scope and scale, Birds and People explores and celebrates this relationship and draws upon Mark Cocker’s 40 years of observing and thinking about birds. Part natural history and part cultural study, it describes and maps the entire spectrum of our engagements with birds, drawing in themes of history, literature, art, cuisine, language, lore, politics and the environment. In the end, this is a book as much about us as it is about birds. Birds and People has been stunningly illustrated by one of Europe’s best wildlife photographers, David Tipling, who has travelled in 39 countries on seven continents to produce a breathtaking and unique collection of photographs. The book is as important for its visual riches as it is for its groundbreaking content. Birds and People is also exceptional in that the author has solicited contributions from people worldwide. Personal anecdotes and stories have come from more than 650 individuals in 81 different countries. They range from university academics to Mongolian eagle hunters, and from Amerindian shamans to some of the most celebrated writers of our age. The sheer multitude of voices in this global chorus means that Birds and People is both a source book on why we cherish birds and a powerful testament to their importance for all humanity.

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.
