Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Structure and Classification of Birds It was the intention of my predecessor in the office of Prosector to the Zoological Society, the late Professor Garrod, F.R.S., to write a treatise upon bird anatomy. This intention was so far realised that a nearly complete account of the anatomy of the fowl, with the appropriate illustrations, was actually drawn up; it was proposed that this should be followed by a second part, in which the general anatomical characters of the different groups of birds were to be stated. Of this second part I have beside me some thirty sheets of MS. Professor Garrod's successor in the post of Prosector to the Zoological Society, the late Mr. W. A. Forbes, had every intention of finishing this work commenced; but unfortunately death took place before any actual additions had been made to the MS. left by his predecessor. I have, on the kind encouragement of Mr. Sclater, determined to make an attempt to carry out this plan of my two forerunners, and the present volume is the result. It must be admitted that a handbook upon bird anatomy was more wanted at the time that it was first conceived by Mr. Garrod than it is at the present day. Zoologists had then nothing of a general character save the incomplete fragment of Bronn's Thierreich and the sections devoted to bird anatomy in such comprehensive works as those of Meckel and Cuvier. We have now two treatises of first-rate merit, that of Furbringer and Dr. Gadow's completion of the section 'Aves' in Bronn's 'Thierreich.'

Book excerpt: It may not seem important to specifically define the general term "bird" but in doing so every birder can gain a greater appreciation of the animals they love to watch. By understanding the similarities all birds share, we can better notice, appreciate, and enjoy the individual characteristics that make each bird species unique. When we notice those differences more easily, we become better birders and are well on our way to seeing hundreds or thousands of the world's unique bird species.All birds are classified as members of the Kindom Animalia, Phylum Chordata, and Class Aves. While this may seem to be an arbitrary, artificial classification, this general grouping emphasizes that birds are related through many of the characteristics they share, including: Vertebrates: All birds have a backbone, which places them in the Phylum Chordata. Unlike most other vertebrates, however, birds have a lighter skeletal structure filled with hollows, gaps, and air sacs to keep birds lightweight so they can fly more efficiently. Feathers: All birds have evolved feathers, composed of keratin and other proteins and light-reflecting pigments, to serve as body insulation. Different types of feathers may also be ornamental, such as plumes, crests, or streamers. Other feather types help birds control their flight, while some feathers, such as down, are strictly for insulation. Wings: Wings are one of the most defining characteristics of birds. Even flightless birds have vestigial or adapted wings or flippers they may use for swimming, threat displays, or courtship dances. The size and shape of wings vary between species based on how the bird flies and wing markings are useful to identify bird species. Bill: All birds have a bony, keratin-covered projection forming their mouth. This bill is frequently evolved for specific bird diet types, and many birds also use their bills as tools for carrying, drumming, drilling, preening, and other tasks. Some birds even use their bills as weapons or to help regulate body temperature. Warm-blooded: All birds are endothermic, which means they generate their own internal body heat and do not rely exclusively on their environment to maintain their temperature. While many birds will sun themselves to help regulate their temperature, sunning has more than one purpose and is not solely for body temperature maintenance. High metabolism: Birds have a high, efficient metabolism that quickly turns food into usable energy. They have a four-chambered heart and high respiratory rate as well, which helps them be efficient and agile fliers as well as maintain their high body temperatures. Bipedal: All birds have two legs used for perching, walking, hopping, or running. Different types of birds have evolved different leg shapes and lengths to suit their needs. For example, wading birds have thin, long legs suitable for moving through deeper water, while raptors have thicker, more powerful legs for capturing prey. Furcula: Though not visible to birders, every bird has a furcula, or wishbone, that protects the chest cavity during wing beats. This keeps the bird's chest organs safe from excessive pressure as the wings move and birds change altitude. Egg-laying: All birds lay amniotic eggs as part of their reproductive cycle. The eggs have a hard shell and require incubation to continue development until hatching. Egg size, shape, and markings vary for each species, as does the number of eggs laid, necessary incubation time, and the condition of the chicks at hatching. Communication: Birds have highly developed communication skills, and many bird species communicate vocally through elaborate songs and calls. Nonverbal bird sounds are also part of their communication abilities. For many species, extensive communication is part of courtship behavior, territorial defense, parent-chick recognition, and community cooperation.

Book excerpt: 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.
