Physiological adaptations for breeding in birds
Physiological Adaptations for Breeding in Birdsis the most current and comprehensive account of research on avian reproduction. It develops two unique themes: the consideration of female avian reproductive physiology and ecology, and an emphasis on individual variation in life-history traits. Tony Williams investigates the physiological, metabolic, energetic, and hormonal mechanisms that underpin individual variation in the key female-specific reproductive traits and the trade-offs between these traits that determine variation in fitness.
The core of the book deals with the avian reproductive cycle, from seasonal gonadal development, through egg laying and incubation, to chick rearing. Reproduction is considered in the context of the annual cycle and through an individual's entire life history. The book focuses on timing of breeding, clutch size, egg size and egg quality, and parental care. It also provides a primer on female reproductive physiology and considers trade-offs and carryover effects between reproduction and other life-history stages. In each chapter, Williams describes individual variation in the trait of interest and the evolutionary context for trait variation. He argues that there is only a rudimentary, and in some cases nonexistent, understanding of the physiological mechanisms that underpin individual variation in the major reproductive life-history traits, and that research efforts should refocus on these key unresolved problems by incorporating detailed physiological studies into existing long-term population studies, generating a new synthesis of physiology, ecology, and evolutionary biology.

Bird day : a story of 24 hours and 24 avian lives
\"From morning to night and from the Antarctic to the equator, birds have busy days. In this short book, ornithologist Mark E. Hauber shows readers exactly how birds spend their time. Each of the book's twenty-four brief chapters covers a single bird and a single hour. At 1:00 in the night, we meet a nearly-blind kiwi, hunting with smell for earthworm prey. Later that morning, at 11:00, we float alongside a common pochard, a duck that can sleep with one eye open to avoid predators and bumping into other birds. At 8:00 that evening, we spot a hawk able to swallow bats whole in mid-flight, gorging on up to fifteen in rapid succession before retreating into the darkness. For each chapter, award-winning artist Tony Angell has depicted these scenes with his signature linocut-style illustrations-which grow increasingly light and then dark as our bird day passes\"-- Provided by publisher.

The atlas of birds : diversity, behavior, and conservation
\"The Atlas of Birds captures the breathtaking diversity of birds, and illuminates their conservation status around the world. Full-color maps show where birds are found, both by country and terrain, and reveal how an astounding variety of behavioral adaptations -- from flight and feeding to nest building and song -- have enabled them to thrive in virtually every habitat on Earth. Maps of individual journeys and global flyways chart the amazing phenomenon of bird migration, while bird classification is explained using maps for each order and many key families. Conservation provides a strong focus throughout, with maps illustrating where and why birds are most under threat, and what is being done to protect them. Separate sections examine key factors influencing their distribution and endangering their survival, from deforestation and climate change to invasive species and the cage-bird trade. Bird groups most affected, such as island endemics, are highlighted, while a fascinating chapter explores the complex historical relationship between birds and humans, with maps and data for everything from poultry farming to birdwatching. The maps are supported by an authoritative text that uses the very latest data and case studies from BirdLife International. Packed with sumptuous photos, original diagrams, and imaginative graphics that bring the numbers to life, this book is a stunning and timely insight into perhaps the most colorful and intriguing group of organisms on our planet\"--Front flap.
