This collection of maps of distribution of breeding birds in Alberta is arranged by order and family. Each map shows evidence of nesting (confirmed, probable, possible, observed) with description and illustration of the bird. Extensive bibliography, index of bird names in English, Latin and French, and list of migrants.
An illustrated survey of the world's most endangered birds This illustrated book vividly depicts the most endangered birds in the world and provides the latest information on the threats each species faces and the measures being taken to save them. Today, 571 bird species are classified as critically endangered or endangered, and a further four now exist only in captivity. This landmark book features stunning photographs of 500 of these species—the results of a prestigious international photographic competition organized specifically for this book. It also showcases paintings by acclaimed wildlife artist Tomasz Cofta of the 75 species for which no photos are known to exist. The World's Rarest Birds has introductory chapters that explain the threats to birds, the ways threat categories are applied, and the distinction between threat and rarity. The book is divided into seven regional sections—Europe and the Middle East; Africa and Madagascar; Asia; Australasia; Oceanic Islands; North America, Central America, and the Caribbean; and South America. Each section includes an illustrated directory to the bird species under threat there, and gives a concise description of distribution, status, population, key threats, and conservation needs. This one-of-a-kind book also provides coverage of 62 data-deficient species.
"Part I outlines the habitats, ecology, and bird geography of the Rocky Mountains north of the New Mexico-Colorado border, including recent changes in the ecology and avifauna of the region. It provides detailed lists of major birding locations and guidance about where to search for specific Rocky Mountain birds. Part 2 considers all 328 regional species individually, with information on their status, habitats and ecology, suggested viewing locations, and population."--Back cover
Although the 12 species representing three waterfowl tribes described in this volume are not closely related, they fortuitously provide an instructive example of adaptive evolutionary radiation within the much larger waterfowl lineage (the family Anatidae), especially as to their divergent morphologies, life histories, and social behaviors. The whistling-ducks (Dendrocygna), with three known North American species, are notable for their permanent pair-bonds, extended biparental family care, and strong social cohesion. In contrast, males of the five typical pochards of North American diving ducks (Aythya) establish monogamous pair-bonds that are maintained only long enough to assure that the female's eggs are fertilized. The endpoint of this behavioral gradient, promiscuity or polygyny, exists among at least some of the typical stifftails (Oxyura). Such diverse reproductive strategies have exerted powerful evolutionary influences on interspecies variations in sexual dimorphism, sexual behavior, anatomy, ecology, and other traits. This volume includes more than 63,000 words, plus some 200 maps, photos, drawings, and sketches, and nearly 650 literature citations. It is the last of five volumes that describe all 55 waterfowl species that have been historically documented in North America; collectively, the volumes total over 300,000 words, with nearly 3,000 literature citations, and more than 600 maps, photos, drawings, and sketches.
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
Sparrows are as complicated as they are common. This is an essential guide to identifying 76 kinds, along with a fascinating history of human interactions with them. What, exactly, is a sparrow? All birders (and many non‑birders) have essentially the same mental image of a pelican, a duck, or a flamingo, and a guide dedicated to waxwings or kingfishers would need nothing more than a sketch and a single sentence to satisfactorily identify its subject. Sparrows are harder to pin down. This book covers one family (Passerellidae), which includes towhees and juncos, and 76 members of the sparrow clan. Birds have a human history, too, beginning with their significance to native cultures and continuing through their discovery by science, their taxonomic fortunes and misfortunes, and their prospects for survival in a world with ever less space for wild creatures. This book includes not just facts and measurements, but stories--of how birds got their names and how they were discovered--of their entanglement with human history.
