A Guide to the Identification and Natural History of the Sparrows of the United States and Canada provides comprehensive information on all the features that make possible identification of all 62 species of sparrows that occur in North America. The text gives detailed descriptions of the summer, winter, and juvenile plumages of each species, as well as comparisons with similar species. The species accounts are illustrated with range maps and superb line drawings showing behavioral postures and, where useful, fine features of tail feather patterns. The 27 color plates splendidly illustrate the various plumages of each species with the emphasis on the distinctive appearance of birds of different sex, age, and geographic regions. This beautiful and authoritative book is a must for the library of all keen birders living in and visiting North America. Species accounts include discussions of species': * Identification * Measurements * Voice * Habitat * Ecology * Nesting biology * Distribution * Taxonomy * Geographic variations * Historical and present status

This book is the first comprehensive guide to all the Old World buntings and North American sparrows. Buntings and North American sparrows offer a great identification challenge. Many of the long distance migrants are notable wanderers, with a strong tendency to vagrancy, while others are rare and local. Some of the Asian buntings and tropical sparrows are still poorly known, and the skulking habits of some species add to the challenge. Most male buntings acquire a bright plumage, but the American sparrows acquire this exceptionally, rather than as the rule. Many sparrows and female buntings appear to be rather dull brown birds, but a closer look will reveal intricate and often quite beautiful plumage; with these birds, the field marks that will enable positive identification are to be found in minute feather detail. This book includes 39 plates in full colour depicting all the species and distinct races. In the systematic section each species account is divided into sections: the identification section summarises important field marks; the description section details plumage and bare part characteristics for all ages and sexes; geographical variation covers taxonomy, and other sections give detailed measurements, descriptions of moult and ageing, habits, voice, status and habitat, distribution and movements, and references. A range map is included for each species. This beautifully presented book will for many years to come help solve the identification problems posed by a delightful and sought-after family of birds.

In a comprehensive investigation of macrogeographic variation in the Plain Titmouse (Parus inornatus) complex in western North America, the author assessed population-level patterns of differentiation in morphometric, colorimetric, allozymic, mtDNA, and vocal characters. These suites of traits showed broad geographic concordance, distinguishing Pacific slope from interior populations. These two groups of populations are treated as sibling species.

In Book of Birds: Introduction to Ornithology, John Faaborg, renowned expert on avian ecology and conservation, brings a fresh and accessible sensibility to the study of ornithology. In this beautifully illustrated volume, Faaborg’s approachable writing style will engage students and birders alike while introducing them to the study of the evolution, taxonomy, anatomy, physiology, diversity, and behavior of birds. With its unique focus on ecology, the text emphasizes birds’ relationships with the environment and other species while showing the amazing diversity of avian life. Faaborg pays special attention to the roles that competition, community structure, and reproductive behavior play in the astonishingly varied and interesting lives of birds seen around the world. He discusses variations in anatomy, morphology, and behavior; explains why such vast diversity exists; and explores the ways in which different birds can share the same spaces. Artist Claire Faaborg brings the science behind this diversity to life through her unique, hand-drawn artwork throughout the book. Combining vibrant visuals and knowledgeable insights, Book of Birds offers readers a firm foundation in the field of ornithology and an invaluable resource for understanding birds from an ecological and evolutionary perspective.
