Book Description
The bird book for birders and nonbirders alike that will excite and inspire by providing a new and deeper understanding of what common, mostly backyard, birds are doing—and why: "Can birds smell?"; "Is this the same cardinal that was at my feeder last year?"; "Do robins 'hear' worms?" "The book's beauty mirrors the beauty of birds it describes so marvelously." —NPR In What It's Like to Be a Bird, David Sibley answers the most frequently asked questions about the birds we see most often. This special, large-format volume is geared as much to nonbirders as it is to the out-and-out obsessed, covering more than two hundred species and including more than 330 new illustrations by the author. While its focus is on familiar backyard birds—blue jays, nuthatches, chickadees—it also examines certain species that can be fairly easily observed, such as the seashore-dwelling Atlantic puffin. David Sibley's exacting artwork and wide-ranging expertise bring observed behaviors vividly to life. (For most species, the primary illustration is reproduced life-sized.) And while the text is aimed at adults—including fascinating new scientific research on the myriad ways birds have adapted to environmental changes—it is nontechnical, making it the perfect occasion for parents and grandparents to share their love of birds with young children, who will delight in the big, full-color illustrations of birds in action. Unlike any other book he has written, What It's Like to Be a Bird is poised to bring a whole new audience to David Sibley's world of birds.

BLACKWELL’S FIVE-MINUTE VETERINARY CONSULT: AVIAN Quick reference to essential information on 200 diseases and conditions commonly seen in birds in clinical practice Covering topics ranging from infectious and non-infectious diseases to diseases by organ system, Blackwell’s Five-Minute Veterinary Consult: Avian fills a unique niche by providing comprehensive information on common topics in avian medicine in a highly organized and efficient manner, allowing busy practitioners and students to quickly find much needed information. A companion website provides algorithms, procedure guides, and client education handouts, which can be downloaded, edited, and given to clients. Written by the leading experts in the field, this newly revised Second Edition offers close to 200 identically formatted topics on avian conditions, with updated and expanded information on non-infectious disease topics like neoplasia, beak malocclusion, diseases of the bursa, nails, and tongue, among others, and infectious disease topics such as herpesviruses, helminthiasis, arboviruses and backyard poultry infectious diseases. This latest edition has been expanded by more than 50% and numerous subjects have been restructured and expanded. Other topics covered in Blackwell’s Five-Minute Veterinary Consult: Avian include: Viral Diseases including circovirus, bornavirus, avian influenza, west nile virus, polyomavirus, poxvirus, and herpesviruses Bacterial Diseases including colibacillosis, campylobacteriosis, chlamydiosis, pasteurellosis, clostridiosis, salmonellosis, and mycoplasmosis Fungal Diseases including aspergillosis, candidiasis, and macrorhabdosis Parasites including flagellates, coccidia, myiasis, ectoparasites, helminths, and toxicosis including iatrogenic, ingested, airborne, algal biotoxins, heavy metals, and pesticides Orthopedic and traumatic conditions such as beak injuries, neurologic trauma, fractures, luxations, joint diseases and wounds, with neoplasia by organ system Critical Care including hypotension, respiratory distress, seizures, hemorrhage, pain, and internal medicine including cardiac disease, cloacal diseases, ocular diseases, diabetes insipidus, atherosclerosis and thyroid diseases For veterinary students, busy avian practitioners, practitioners in mixed practice who want quick access to reliable information, and emergency clinicians presented with the occasional bird, Blackwell’s Five-Minute Veterinary Consult: Avian is an invaluable, accessible, and highly practical reference to add to your practice library.

Book Description
This book comprehensively summarizes the biological mechanisms of coloration and pattern formation of animals at molecular and cellular level, offering up-to-date knowledge derived from remarkable progress in the last 10 years. The brilliant coloration, conspicuous patterns and spectacular color changes displayed by some vertebrates and invertebrates are generally their strategies of the utmost importance for survival. Consists of mainly three parts, starts with introductory chapter, such as Pigments and Pigment Organelles, Developmental Genetics of Pigment Cell Formation, Adult Pigment Patterns, and Color Changes, this book introduces new pigment compounds in addition to classically known pigments and organelles, explains how the generation of multiple types of pigment cell is genetically controlled, describes the mechanisms underlying the zebrafish stripe formation as well as other animals and also summarizes the mechanism of physiological and morphological color changes of teleost, amphibian and cephalopod. Written by experts in the field, this book will be essential reading for graduate students and researchers in biological fields who are interested in pigmentation mechanisms of animals.

Book Description
Cabej (biology, U. of Tirana, Albania) explains the epigenetic principles of evolution (as opposed to the theory of evolution as determined by changes in genes) and reconstructs the developmental mechanisms of evolutionary changes in metazoans, based on empirical evidence. He focuses on the mechanisms of the generation of the evolutionary innovations from the influence of environment on heredity rather than the role of natural selection. He discusses control systems and determination of phenotypic traits in metazoans, neural manipulation of gene expression, epigenetic control of reproduction and early development, neural control of postphylotypic development, and the epigenetic system of inheritance. He follows with description of neural-developmental premises of evolutionary adaptation, including evolution and stress responses and behavioral adaptation to changes in environment, ontogeny, and intragenerational developmental plasticity; epigenetics of circumevolutionary phenomena and the mechanism of evolutionary change, including transgenerational developmental plasticity and the evolution of metazoans and their control system; and the origins of evolutionary novelty, evolution by loss or by reverting to ancestral characters, neural crest-determined evolutionary novelties, evolutionary convergences, species and allopatric speciation, and sympatric speciation. He presents the available evidence for his theory, rather than illustrating an established theory, and includes a comparative presentation of the neo-Darwinian view to his epigenetic explanation.

Book Description
Pathology of Pet and Aviary Birds A complete reference for veterinary pathologists, residents, and students interested in avian diseases The revised third edition of Pathology of Pet and Aviary Birds delivers a comprehensive reference to gross and microscopic lesions found in birds, as well as the implications of these diseases. This third edition includes improved coverage of normal anatomy and of advanced diagnostic techniques, including special stains, immunohistochemistry, in situ hybridization, and molecular diagnostics. The authors offer an extensive collection of more than 1200 high-quality, full-color images. New chapters cover the postmortem examination; gross and microscopic anatomy; advanced diagnostics; and cytology. Specific chapters address diseases of passerines, Columbidae, and raptors, and other chapters are intuitively organized by body system. The book also provides: A thorough introduction to the preparation and interpretation of cytological samples Comprehensive tables of infectious diseases and published avian primers and IHC markers Practical discussion of diseases of the liver, urinary system, reproductive system, respiratory system, cardiovascular system, nervous system, alimentary system, integument, special senses, and more. High-quality and annotated macroscopic and microscopic images that bolster the text and benefit the reader Pathology of Pet and Aviary Birds is an essential resource for veterinary pathologists and pathology residents, and will also benefit avian practitioners and veterinary students with an interest in diseases of pet birds and birds in avicultural collections. As many diseases in captive birds also manifest in wild birds, the book will appeal to those interested in the diseases and pathology of wild birds.
