From the lifelong devotion of the American crow to the dalliances of the eastern bluebird, from the bald eagle’s dazzling aerial display to the male ruby-throated hummingbird’s reputation as a “deadbeat dad” — courtship, mating, and parenting differ dramatically among birds. Ornithologist and author Laura Erickson takes readers on a romance-fueled romp through the love lives of 35 species, exploring the diversity of avian approaches to pairing up. Each species spotlight pairs Erickson’s remarkable depth of scientific knowledge with her talent for drawing humorous and insightful parallels between human and bird. The result is a riveting read for bird-watchers and nature lovers alike.

Urbanization is next to global warming the largest threat to biodiversity. Indeed, it is becoming increasingly evident that many bird species get locally extinct as a result of urban development. However, many bird species benefit from urbanization, especially through the abundance of human-provided resources, and increase in abundance and densities. These birds are intriguing to study in relation to its resilience and adaption to urban environments, but also in relation to its susceptibility and the potential costs of urban life. This Research Topic consisting of 30 articles (one review, two meta-analyzes and 27 original data papers) provides insights into species and population responses to urbanization through diverse lenses, including biogeography, community ecology, behaviour, life history evolution, and physiology.

A stunningly illustrated look at the mating and parenting lives of the world's birds Bird Love looks at the extraordinary range of mating systems in the avian world, exploring all the stages from courtship and nest-building to protecting eggs and raising chicks. It delves into the reasons why some species, such as the wattled jacana, rely on males to do all the childcare, while others, such as cuckoos and honeyguides, dump their eggs in the nests of others to raise. For some birds, reciprocal promiscuity pays off: both male and female dunnocks will rear the most chicks by mating with as many partners as possible. For others, long-term monogamy is the only way to ensure their offspring survive. The book explores the wide variety of ways birds make sure they find a mate in the first place, including how many male birds employ elaborate tactics to show how sexy they are. Gathering in leks to display to females, they dance, pose, or parade to sell their suitability as a mate. Other birds attract a partner with their building skills: female bowerbirds rate brains above beauty, so males construct elaborate bowers with twig avenues and cleared courtyards to impress them. Looking at the differing levels of parenting skills across species around the world, we see why a tenth of bird species, including the fairy-wrens of Australia, have helpers at the nest who forgo their own reproduction to assist the breeding pair; how brood parasites and their hosts have engaged in evolutionary arms races; and how monogamous pairs share—or relinquish—their responsibilities. Illustrated throughout with beautiful photographs, Bird Love is a celebration of the global diversity of avian reproductive strategies.

All animals are equal - but some, as George Orwell said, are more equal than others, and birds, most people would surely agree, are in the very first rank. They can do almost everything that mammals can do - and more. By mastering flight, they have a way of living that encompasses the whole world. In The Secret Life of Birds, Colin Tudge explores the life of birds, all around the globe. From the secrets of migration to their complicated family lives, their differing habitats and survival techniques to the secrets of flight, this is a fascinating account of how birds live, why they matter, and whether they really are dinosaurs. Colin Tudge shows how birds - who are like us in the general sense but very different in the particulars - live and think. For birds have minds: they feel, they are aware, they work things out. And so, by considering the birds, asking how and why it is possible for them to be so different, we gain insight into ourselves. Birds are beautiful, lively, intriguing - and all around us. This rich and endlessly absorbing book opens up their lives to everyone.

The novel tells the story, in the first person, of a young black male ex-student's obsession with a young English woman, Veronica Slater, whom he encounters on the segregated Durban beachfront. It is the heyday of apartheid. Although not a word is exchanged, a strong erotic bond develops between the two of them, culminating in what is later seen as a rape and for which the narrator gets the death sentence. In an absolute tour de force the narrator, only ever referred to as Mr Sibiya, waiting to be executed, writes down his story - reconstructing bit by bit not only his own and a brief history of his family, but also his obsession with the white girl, the court proceedings, and his encounters with Dr Dufre, a Swiss criminologist who has been granted permission of compile a dossier of the case. One of the most remarkable things about the novel is the narrator's ability to be objective, to view himself and the series of events almost dispassionately.

Some birds mate for life, while others have many partners. Why? In this book, fourteen classic studies of bird behaviour are brought together to compare the different partnership patterns from ecological and evolutionary perspectives. Often there is a battle of the sexes, as individual birds behave in the way that serves their best interests. Introductory and concluding chapters review the latest thinking on this fascinating subject. - ;Some birds mate for life, while others have many partners. In this book, fourteen studies are brought together to compare different partnership patterns from ecological and evolutionary perspectives. The subjects have been chosen to include the same species living in different habitats (Sparrowhawks) and at different population densities (Great Tits). There are comparisons between closely related species (Mute Swans and Bewick's Swans). The studies span the globe and the behavioural gradient, from Iceland's strictly monogamous Whooper Swans to Australia's sexually promiscuous Splendid Fairy-wrens. In all cases, sexual and social relationships strongly influence a bird's survival and breeding success. -

Birds show bewildering diversity in their life histories, mating systems and risk of extinction. Why do albatrosses delay reproduction for the first 12 years of their life while zebra finches breed in their first year ? Why are fairy-wrens so sexually promiscuous while swans show lifelongmonogamy? Why are over a quarter of parrot species threatened with global extinction while woodpeckers and cuckoos remain secure? Some of these topics, such as delayed onset of breeding in seabirds, are classic problems in evolutionary ecology, while others have arisen in the last decade, such as genetic mating systems and extinction. Birds offer a unique opportunity for investigating these questions because they areexceptionally well-studied in the wild. By employing phylogenetic comparative methods and a database of up to 3,000 species, the authors identify the ecological and evolutionary basis of many of these intriguing questions. They also highlight remaining puzzles and identify a series of challenges forfuture investigation. This is the most comprehensive reappraisal of avian diversity since David Lack's classic "Ecological Adaptations for Breeding in Birds". It is also the most extensive application of modern comparative methods yet undertaken. This novel approach demonstrates how an evolutionary perspective canreveal the general ecological processes that underpin contemporary avian diversity on a global scale.

With his distinctively witty, anecdotal, and disarming voice, John Yow now journeys to the shore and shares his encounters with some of the most familiar and beloved coastal birds. Out of his travels--from North Carolina's Outer Banks, down the Atlantic coast, and westward along the Gulf of Mexico--come colorful accounts of twenty-eight species, from ubiquitous beach birds like sanderlings and laughing gulls to wonders of nature like roseate spoonbills and the American avocets. Along the way, Yow delves deeply into the birds' habits and behaviors, experiencing and relating the fascination that leads many an amateur naturalist to become the most unusual of species--a birder. Seasonally organized chapters explore the improbable, the wonderful, and the amusing aspects of these birds' lives. Yow embellishes his observations with field notes, anecdotes, and stories from some of America's finest naturalists--including John James Audubon, Arthur Cleveland Bent, Rachel Carson, and Peter Matthiessen. Combining the endless fascination of bird life with the pleasure of good reading, The Armchair Birder Goes Coastal is the perfect companion for any nature lover's next trip to the beach.
