Original ed. published as: Classifying birds.

Explains the things, such as feathers and beaks, that define birds as birds, using a herring gull as an example.

Develop your high school students' understanding of argumentation and evidence-based reasoning with this comprehensive book. Like three guides in one 'Scientific Argumentation in Biology' combines theory, practice, and biology content.

The average person can name more bird species than they think, but do we really know what a bird “species” is? This open access book takes up several fascinating aspects of bird life to elucidate this basic concept in biology. From genetic and physiological basics to the phenomena of bird song and bird migration, it analyzes various interactions of birds – with their environment and other birds. Lastly, it shows imminent threats to birds in the Anthropocene, the era of global human impact. Although it seemed to be easy to define bird species, the advent of modern methods has challenged species definition and led to a multidisciplinary approach to classifying birds. One outstanding new toolbox comes with the more and more reasonably priced acquisition of whole-genome sequences that allow causative analyses of how bird species diversify. Speciation has reached a final stage when daughter species are reproductively isolated, but this stage is not easily detectable from the phenotype we observe. Culturally transmitted traits such as bird song seem to speed up speciation processes, while another behavioral trait, migration, helps birds to find food resources, and also coincides with higher chances of reaching new, inhabitable areas. In general, distribution is a major key to understanding speciation in birds. Examples of ecological speciation can be found in birds, and the constant interaction of birds with their biotic environment also contributes to evolutionary changes. In the Anthropocene, birds are confronted with rapid changes that are highly threatening for some species. Climate change forces birds to move their ranges, but may also disrupt well-established interactions between climate, vegetation, and food sources. This book brings together various disciplines involved in observing bird species come into existence, modify, and vanish. It is a rich resource for bird enthusiasts who want to understand various processes at the cutting edge of current research in more detail. At the same time it offers students the opportunity to see primarily unconnected, but booming big-data approaches such as genomics and biogeography meet in a topic of broad interest. Lastly, the book enables conservationists to better understand the uncertainties surrounding “species” as entities of protection.

Selected by Forbes.com as one of the 12 best books about birds and birding in 2016 This much-anticipated third edition of the Handbook of Bird Biology is an essential and comprehensive resource for everyone interested in learning more about birds, from casual bird watchers to formal students of ornithology. Wherever you study birds your enjoyment will be enhanced by a better understanding of the incredible diversity of avian lifestyles. Arising from the renowned Cornell Lab of Ornithology and authored by a team of experts from around the world, the Handbook covers all aspects of avian diversity, behaviour, ecology, evolution, physiology, and conservation. Using examples drawn from birds found in every corner of the globe, it explores and distills the many scientific discoveries that have made birds one of our best known - and best loved - parts of the natural world. This edition has been completely revised and is presented with more than 800 full color images. It provides readers with a tool for life-long learning about birds and is suitable for bird watchers and ornithology students, as well as for ecologists, conservationists, and resource managers who work with birds. The Handbook of Bird Biology is the companion volume to the Cornell Lab’s renowned distance learning course, Ornithology: Comprehensive Bird Biology.

This lavishly illustrated trade reference to mammals, birds, reptiles, amphibians, fishes, and invertebrates features hundreds of glorious photos, masterful illustrations, and informative maps.

Delve into the fascinating world of birds through astonishing photography and clear explanations in this absorbing global guide Birds are dinosaurs, with a history going back millions of years. Our fascination with them runs deep in history and our close association is reflected in creation stories, myths, legends, songs, and children's stories. This book explores both the natural history of birds and that deep cultural connection. From their evolution and anatomy to their behavior and diversity, spanning tiny dunnocks hiding in bushes to ostriches strong enough to knock out a lion. Articles cover a group, such as hawks, finches, swans, or birds of paradise, moving the focus away from a predictable species-by-species account and allowing for truly global coverage. Discover the bold nature of European Robins and why they are associated with Christmas; the mythical Alkonost, with the body of a bird of paradise but the head of a woman; and learn about eagles, from their hunting prowess to the myriad stories and symbolism associated with them. Packed with information, and beautiful photography and illustrations, The Bird Book is a must-have for nature enthusiasts.

With expanded text and even larger colour illustrations, this guide covers every species and every plumage you will see, with detailed information on identification, habitat and voice.

Explains what mammals are and how they differ from other animals, with an overview of the life cycle of a variety of mammals, including pouched mammals, sea mammals, flying mammals, and humans.
