Handbook Of Avian Hybrids Of The World

With more than 5,000 works cited, Handbook of Avian Hybrids of the World is the greatest compendium of information ever published on hybridization in birds. Worldwide in scope, it provides information on all reported avian crosses, not only those occurring in captivity, but also in a natural setting (approximately 4,000 crosses are covered). This book is a basic reference, intended both for the serious birder and the professional biologist. McCarthy's work fills a need for reference material that takes into account the last half century of data. It will be of interest to workers in a wide variety of fields, ranging from animal behavior to genetics, ecology, zoology, and systematics. In fact, it will make fascinating reading for anyone interested in birds and the natural world.

A full-color photographic guide to these captivating and challenging birds This is the essential identification guide to the terns, noddies, and skimmers of North America. Covering every species and featuring hundreds of high-quality color images, this book is the ideal companion for anyone interested in this charismatic but sometimes challenging group of seabirds. Detailed species accounts describe the size of each bird as it appears in the field along with structure, behavior, flight style, vocalizations, subspecies, and North American and worldwide ranges. An incisive introduction lays out a remarkably simple approach to identification that focuses on key elements and addresses how to avoid getting bogged down in the variability of appearance. This state-of-the-art guide also provides additional in-depth coverage of the two most challenging groups of terns, Sterna terns and crested terns, aiding field identification while also highlighting the beauty and elegance of these marvelous seabirds. Features more than 325 stunning color photos, with side-by-side comparisons of similar species throughout Includes detailed captions for each image that describe age and key identification traits Covers 19 species found in North America, including the most frequent vagrants Presents a unique, simplified approach to field identification Explains the fundamentals of molts, plumages, and hybridization Provides in-depth coverage of Sterna terns and crested terns

"A highly illustrated, portable field guide to two families of flycatchers, Myiarchus and Tyrannus, some of the most difficult birds to ID in the field"--

Telenothians: An Inquiry into the Limits of Hybridization is a collection of information bearing on a single primary question: How different can two organisms be if they are to mate and produce offspring together? The focus is on animals belonging to Phylum Vertebrata (animals with a backbone). Gleaned from a wide array of sources, ancient and modern, the evidence is drawn from medical reports, scientific journals, newspapers, magazines, viral videos and dusty tomes. Between the two covers of this book, the impossible becomes fact.

Much of Charles Darwin's groundbreaking work as an evolutionary biologist stemmed from his study of birds. It is universally acknowledged that Darwin's observation of bird groups and species like the Galapagos finches, mockingbirds, and rock doves was critical to the development of his theories on natural selection, evolution, and sexual selection. The significant number of diverse birds that Darwin covered in his published works represents a most substantial ornithological contribution. His major books alone contain reference to and consideration of almost 500 bird species, as well as interesting and pertinent discussion of over 100 ornithological topics. "Charles Darwin's Birds" is a comprehensive treatment of Darwin's work as an ornithologist. Clifford Frith discusses every ornithological topic and bird species that Darwin researched, providing a complete historical survey of his published writing on birds. Through this, we learn how Darwin became an increasingly skilled and eventually exceptional ornithologist, and how his relationships grew with contemporary scientists like John Gould. It examines how Darwin was influenced by birds, and how the major themes of his research developed through his study of them. The book also features 4 appendices, which contain brief accounts of every bird species Darwin wrote about, basic ornithological information about each of the species, and a listing of where the species appears in Darwin's work.

"With detailed information about identification, calls, habitat, breeding, nesting, and behavior, this reference guide has the most up-to-date information about natural history, taxonomy, biology, ecology, migration and conservation status."--Book jacket.
