Book excerpt: There is a marked and most unfortunate dichotomy in the studies of avian eggs and hence in the application of new findings in commerce. Thus over the past twenty years there has been a renewed interest in the contribu tions of various parts of an egg to embryo development. This is best illustrated by those studies that have explored the diffusion of respiratory gases across the shell and at long last have provided a fundamental definition of a previously nebulous term, porosity. The activity in this general area has led in the past four years to the publication of three major books dealing with many aspects of egg structure, function and embryogenesis. When brows ing over these books, two developments are evident. First, the advantages that are to be gained by comparative studies. Thus it is now common to see within a single book articles concerned with the eggs of a range of avian species as well as those of reptiles. Second, it is evident that zoologists and physiologists as well as those employed in large breeding firms are all contributing to an improvement of our knowledge of the egg's role in the breeding biology of birds. Comparative studies are a very uncommon feature of studies concerned with bacterial infection of eggs.

Download or read book The Book of Eggs written by Mark E. Hauber and published by University of Chicago Press. This book was released on 2014-08-01 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the brilliantly green and glossy eggs of the Elegant Crested Tinamou—said to be among the most beautiful in the world—to the small brown eggs of the house sparrow that makes its nest in a lamppost and the uniformly brown or white chickens’ eggs found by the dozen in any corner grocery, birds’ eggs have inspired countless biologists, ecologists, and ornithologists, as well as artists, from John James Audubon to the contemporary photographer Rosamond Purcell. For scientists, these vibrant vessels are the source of an array of interesting topics, from the factors responsible for egg coloration to the curious practice of “brood parasitism,” in which the eggs of cuckoos mimic those of other bird species in order to be cunningly concealed among the clutches of unsuspecting foster parents. The Book of Eggs introduces readers to eggs from six hundred species—some endangered or extinct—from around the world and housed mostly at Chicago’s Field Museum of Natural History. Organized by habitat and taxonomy, the entries include newly commissioned photographs that reproduce each egg in full color and at actual size, as well as distribution maps and drawings and descriptions of the birds and their nests where the eggs are kept warm. Birds’ eggs are some of the most colorful and variable natural products in the wild, and each entry is also accompanied by a brief description that includes evolutionary explanations for the wide variety of colors and patterns, from camouflage designed to protect against predation, to thermoregulatory adaptations, to adjustments for the circumstances of a particular habitat or season. Throughout the book are fascinating facts to pique the curiosity of binocular-toting birdwatchers and budding amateurs alike. Female mallards, for instance, invest more energy to produce larger eggs when faced with the genetic windfall of an attractive mate. Some seabirds, like the cliff-dwelling guillemot, have adapted to produce long, pointed eggs, whose uneven weight distribution prevents them from rolling off rocky ledges into the sea. A visually stunning and scientifically engaging guide to six hundred of the most intriguing eggs, from the pea-sized progeny of the smallest of hummingbirds to the eggs of the largest living bird, the ostrich, which can weigh up to five pounds, The Book of Eggs offers readers a rare, up-close look at these remarkable forms of animal life.

Download or read book Developments of the Avian Embryo written by Freeman and published by Springer. This book was released on 2011-10-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book we have described the major events of embryonic development and considered the underlying mechanisms which result in the production of a viable hatchling. We have, as the subtitle of the book indicates, con centrated on behavioural and physiological topics: it is not our purpose to consider the early embryology of the bird - which is adequately covered by other texts - but we have included morphogenetic information where appropriate. The form of the book was dictated by a belief that interest in this aspect of development is not confined to embryologists, biochemists and physiolo gists. Therefore after describing the conditions in which the egg normally develops we have considered first the whole embryo: what it is like at different stages, what it does, how it gets from one position to another within the shell and how, later, it comes to interact with the wider environ ment of the nest. Only after this have we considered the development of the nervous and sensory mechanisms on which this transformation depends and on the problem of the level of behavioural maturity with which the chick emerges from the egg. With the main lines of development described we have, in the second part of the book, turned to a detailed consideration of the physiology of development: ranging from what may be conveniently described as the 'life-support' systems - gaseous exchange, provision of energy, etc. - to the of hormones in avian development.
Download or read book Avian Brood Parasitism written by Manuel Soler and published by Springer. This book was released on 2018-05-02 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brood parasitism has become one of the most flourishing areas of research in evolutionary ecology and one of the best model systems for investigating coevolution. This subject has undergone remarkable advances during the last two decades, but has not been covered by any book in the 21st century. This book offers a comprehensive and up-to-date overview of the fascinating field of avian brood parasitism. The topics covered include conspecific brood parasitism; evolution and phylogenetic history of avian brood parasites; parasitic behaviour used by brood parasites; adaptations and counter-adaptations of brood parasites and their hosts at every stage of the breeding cycle (before laying, egg, chick and fledgling stages); factors affecting the evolution of host defences and parasitic attacks; the role of phenotypic plasticity in host defences; mechanisms driving egg recognition and rejection; evolution of nest sharing or nest killing by brood parasite chicks; begging behaviour in parasitized nests and food delivery by host adults; and recognition of conspecifics by juvenile brood parasites. This volume provides a comprehensive reference resource for readers and researchers with an interest in birds, behaviour and evolution, as well as a source of hypotheses and predictions for future investigations into this dynamic subject.
Download or read book Avian Reproduction written by Tomohiro Sasanami and published by Springer. This book was released on 2017-10-04 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides everything from basic knowledge to the recent understandings of avian reproductive physiology, covering many unique aspects. It will inspire avian biologists as well as researchers in varied fields and will offer important steps towards better fertilization success in birds.In spite of the recent remarkable developments in modern technology, a comprehensive understanding of the reproductive mechanisms is still far in the future due to the diverse reproductive tactics in vertebrates. Birds have highly refined reproductive strategies and some of those strategies are unique to birds. However, together with ongoing progress of the genome analysis of birds and the crying need for further increase in meat and egg production, research on avian reproduction is now accelerating and becoming more important.With contributions by leading scientists, the book explains avian primordial germ cells; the sex-determining mechanism; reproductive endocrinology and immunology; sperm, egg, and egg coat; sperm–egg interaction; polyspermic fertilization; seasonal reproduction; social triggers; hormonal and behavioral changes; broodiness; oviductal sperm storage; and biotechnology. This book is recommended for all researchers and students who are interested in birds or reproduction.
Download or read book The Most Perfect Thing written by Tim Birkhead and published by Bloomsbury Publishing USA. This book was released on 2016-04-12 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: A bird's egg is a nearly perfect survival capsule--an external womb--and one of natural selection's most wonderful creations. Shortlisted for the Royal Society Insight Investment Science Book Prize 2016.One of Forbes' Best Books About Birds and Birding in 2016. Renowned ornithologist Tim Birkhead opens this gripping story as a female guillemot chick hatches, already carrying her full quota of tiny eggs within her undeveloped ovary. As she grows into adulthood, only a few of her eggs mature, are released into the oviduct, and are fertilized by sperm stored from copulation that took place days or weeks earlier. Within a matter of hours, the fragile yolk is surrounded by albumen and the whole is gradually encased within a turquoise jewel of a shell. Soon the fully formed egg is expelled onto a rocky ledge, where it will be incubated for four weeks before a chick emerges and the life cycle begins again. THE MOST PERFECT THING is about how eggs in general are made, fertilized, developed, and hatched. Birkhead uses birds' eggs as wondrous portals into natural history, enlivened by the stories of naturalists and scientists, including Birkhead and his students, whose discoveries have advanced current scientific knowledge of reproduction.
