Book Description
From the renowned author of the New York Times best seller The Sibley Guide to Birds, a comprehensive, beautifully illustrated guide to identifying birds in the field. Sibley's Birding Basics is an essential companion for birders of all skill and experience levels. With Sibley as your guide, learn how to interpret what the feathers, the anatomical structure, the sounds of a bird tell you. When you know the clues that show you why there’s no such thing as, for example, “just a duck” birding will be more fun, and more meaningful. An essential addition to the Sibley shelf! The Sibley Guide to Birds and The Sibley Guide to Bird Life and Behavior are both universally acclaimed as the new standard source of species information. And now David Sibley, America’s premier birder and best-known bird artist, turns his attention to the general characteristics that influence the appearance of all birds, unlocking the clues to their identity. In 200 beautifully rendered illustrations and 16 essays, this scientifically precise volume distills the essence of Sibley’s own experience and skills, providing a solid introduction to “naming” the birds. Birding Basics reviews how one can get started as a birder—the equipment necessary, where and when to go birding, and perhaps most important, the essential things to look for when birds appear in the field—as well as the basic concepts of bird identification and the variations that can change the appearance of a bird over time or in different settings. Sibley also provides critical information on the aspects of avian life that differ from species to species: feathers (color, arrangement, shape, molt), behavior and habitat, and sounds.

Book Description
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.

Book Description
As seen on PBS's American Spring Live, one of America's great nature-writers explores the magic and science of feathers Feathers are an evolutionary marvel: aerodynamic, insulating, beguiling. They date back more than 100 million years. Yet their story has never been fully told.In Feathers, biologist Thor Hanson details a sweeping natural history, as feathers have been used to fly, protect, attract, and adorn through time and place. Applying the research of paleontologists, ornithologists, biologists, engineers, and even art historians, Hanson asks: What are feathers? How did they evolve? What do they mean to us? Engineers call feathers the most efficient insulating material ever discovered, and they are at the root of biology's most enduring debate. They silence the flight of owls and keep penguins dry below the ice. They have decorated queens, jesters, and priests. And they have inked documents from the Constitution to the novels of Jane Austen. Feathers is a captivating and beautiful exploration of this most enchanting object.

Book Description
The world's most revered and eloquent interpreter of evolutionary ideas offers here a work of explanatory force unprecedented in our time--a landmark publication, both for its historical sweep and for its scientific vision. With characteristic attention to detail, Stephen Jay Gould first describes the content and discusses the history and origins of the three core commitments of classical Darwinism: that natural selection works on organisms, not genes or species; that it is almost exclusively the mechanism of adaptive evolutionary change; and that these changes are incremental, not drastic. Next, he examines the three critiques that currently challenge this classic Darwinian edifice: that selection operates on multiple levels, from the gene to the group; that evolution proceeds by a variety of mechanisms, not just natural selection; and that causes operating at broader scales, including catastrophes, have figured prominently in the course of evolution. Then, in a stunning tour de force that will likely stimulate discussion and debate for decades, Gould proposes his own system for integrating these classical commitments and contemporary critiques into a new structure of evolutionary thought. In 2001 the Library of Congress named Stephen Jay Gould one of America's eighty-three Living Legends--people who embody the "quintessentially American ideal of individual creativity, conviction, dedication, and exuberance." Each of these qualities finds full expression in this peerless work, the likes of which the scientific world has not seen--and may not see again--for well over a century.
