An exposition on feathers- their form, function, varieties, and physiology, accompanied by the author's stunning artwork made from feathers.

This classic work forms a complete reference to avian anatomy, with a particular focus on the ways in which structure relates to biology and function. An international team of expert authors each focus on particular organs or organ systems to produce detailed descriptions of all aspects of the anatomy and physiology of birds.

Feathers are one of the most unique characteristics of modern birds and represent the most complex and colourful type of skin derivate within vertebrates, while also fulfilling various biological roles, including flight, thermal insulation, display, and sensory function. For years it was generally assumed that the origin of flight was the main driving force for the evolution of feathers. However, various discoveries of dinosaur species with filamentous body coverings, made over the past 20 years, have fundamentally challenged this idea and produced new evolutionary scenarios for the origin of feathers. This book is devoted to the origin and evolution of feathers, and highlights the impact of palaeontology on this research field by reviewing a number of spectacular fossil discoveries that document the increasing morphological complexity along the evolutionary path to modern birds. Also featuring chapters on fossil feather colours, feather development and its genetic control, the book offers a timely and comprehensive overview of this popular research topic.

The award-winning National Geographic photographer captures the stunning variety and mystery of bird feathers in this acclaimed monograph. Robert Clark’s fascinating and brilliantly colorful images reveal the beauty and myriad functions of a seemingly simple thing: the bird feather. Each exquisitely detailed close-up is paired with informative text about the utility and evolution of the feather it depicts, making this handsome marriage of art and science the ideal gift for bird lovers, natural history buffs, and photography enthusiasts. “Art meets science in a poetic celebration of Earth’s astonishing diversity. Feathers is an intensely beautiful visual taxonomy and a photographic love letter to this poetic feat of evolution.” —Brain Pickings

There is more to a bird than simply feathers. And just because birds evolved from a single flying ancestor doesn't mean they are structurally the same. With 385 stunning drawings depicting 200 species, The Unfeathered bird is a richly illustrated book on bird anatomy that offers refreshingly original insights into what goes on beneath the feathered surface.

The bird book for birders and nonbirders alike that will excite and inspire by providing a new and deeper understanding of what common, mostly backyard, birds are doing—and why: "Can birds smell?"; "Is this the same cardinal that was at my feeder last year?"; "Do robins 'hear' worms?" "The book's beauty mirrors the beauty of birds it describes so marvelously." —NPR In What It's Like to Be a Bird, David Sibley answers the most frequently asked questions about the birds we see most often. This special, large-format volume is geared as much to nonbirders as it is to the out-and-out obsessed, covering more than two hundred species and including more than 330 new illustrations by the author. While its focus is on familiar backyard birds—blue jays, nuthatches, chickadees—it also examines certain species that can be fairly easily observed, such as the seashore-dwelling Atlantic puffin. David Sibley's exacting artwork and wide-ranging expertise bring observed behaviors vividly to life. (For most species, the primary illustration is reproduced life-sized.) And while the text is aimed at adults—including fascinating new scientific research on the myriad ways birds have adapted to environmental changes—it is nontechnical, making it the perfect occasion for parents and grandparents to share their love of birds with young children, who will delight in the big, full-color illustrations of birds in action. Unlike any other book he has written, What It's Like to Be a Bird is poised to bring a whole new audience to David Sibley's world of birds.

"Here is a volume that has no parallel. . . . A good reference book for those interested in the details of avian anatomy."--Science Books & Films "A gold mine of facts. . . . Every library and biology department, as well as every birder, should have a copy close at hand."--Roger Tory Peterson, from the foreword One of the most heavily illustrated ornithology references ever written, Manual or Ornithology is a visual guide to the structure and anatomy of birds--a basic tool for investigation for anyone curious about the fascinating world of birds. A concise atlas of anatomy, it contains more than 200 specially prepared accurate and clear drawings that include material never illustrated before. The text is as informative as the drawings; written at a level appropriate to undergraduate students and to bird lovers in general, it discusses why birds look and act the way they do. Designed to supplement a basic ornithology textbook, the Manual of Ornithology covers systematics and evolution, topography, feathers and flight, the skeleton and musculature, and the digestive, circulatory, respiratory, excretory, reproductive, sensory, and nervous systems of birds, as well as field techniques for watching and studying birds. Each chapter concludes with a list of key references for the topic covered, with a comprehensive bibliography at the end of the volume.
