This book was released on 2015 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change has been linked to an increasing frequency of inclement weather and winter storms. As such, it is important to understand the effects changing weather patterns have on avian species. I investigated the effects of recurrent inclement winter weather cues on glucocorticoid hormones and behaviour of a native Canadian songbird, white-throated sparrows (Zonotrichia albicollis). I used a hypobaric climatic wind tunnel to simulate storms by altering barometric pressure and temperature accordingly, and measured behavioural responses, body composition, and baseline corticosterone levels in birds exposed, or not exposed, to weekly simulated storms. After environmental manipulations, experimental birds had significantly higher fat and lean masses. Baseline corticosterone levels decreased over time in both groups, and time spent at food cups increased over time in both groups as well. Thus, although manipulations did not have a detectable effect on baseline corticosterone, it did affect body composition. This research provides novel experimental evidence that birds detect changing weather patterns and respond appropriately, and indicates that repeated exposure to inclement weather cues directly affects birds' energy reserves.

Download or read book Animal Migration Orientation and Navigation written by Gauthreaux and published by Elsevier. This book was released on 2012-12-02 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal Migration, Orientation, and Navigation presents the various aspects of animal migration, including the evolution of migration, climatic and meteorological influences, and bioenergetics. This book discusses the physiological control, sensory systems, orientation and navigation, and biological clocks and phenology aspects of animal migration. Organized into five chapters, this book begins with an overview of the migration strategies of animals in the context of a space continuum. This text then explains the influence of short- and long-term climatic cycles on the spectrum of migratory patterns in nature. Other chapters consider the energetic requirements of different migration strategies and the energy stores of the migrants. This book discusses as well the physiological basis of animal migration, with emphasis on endocrinal findings on the timing and energetic aspects of different migration strategies. The final chapter deals with the mechanisms used in direction finding by migrating animals. This book is a valuable resource for biologists and ecologists.

Book excerpt: The voices of birds have always been a source of fascination. Nature's Music brings together some of the world's experts on birdsong, to review the advances that have taken place in our understanding of how and why birds sing, what their songs and calls mean, and how they have evolved. All contributors have strived to speak, not only to fellow experts, but also to the general reader. The result is a book of readable science, richly illustrated with recordings and pictures of the sounds of birds. Bird song is much more than just one behaviour of a single, particular group of organisms. It is a model for the study of a wide variety of animal behaviour systems, ecological, evolutionary and neurobiological. Bird song sits at the intersection of breeding, social and cognitive behaviour and ecology. As such interest in this book will extend far beyond the purely ornithological - to behavioural ecologists psychologists and neurobiologists of all kinds.* The scoop on local dialects in birdsong* How birdsongs are used for fighting and flirting* The writers are all international authorities on their subject

Available in PDF, EPUB and Kindle. Book excerpt: Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.
