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.

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.

Download or read book Bird Migration written by Eberhard Gwinner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: E. GWINNER! The phenomenon of bird migration with its large scale dimensions has attracted the attention of naturalists for centuries. Worldwide billions of birds leave their breeding grounds every autumn to migrate to areas with seasonally more favor able conditions. Many of these migrants travel only over a few hundred kilo meters but others cover distances equivalent to the circumference of the earth. Among these long-distance migrants are several billion birds that invade Africa every autumn from their West and Central Palaearctic breeding areas. In the Americas and in Asia the scope of bird migration is of a similar magnitude. Just as impressive as the numbers of birds are their achievements. They have to cope with the enormous energetic costs of long-distance flying. particularly while crossing oceans and deserts that do not allow replenishment of depleted fat reserves. They have to appropriately time the onset and end of migrations. both on a daily and annual basis. And finally. they have to orient their migratory movements in space to reach their species- or population-specific wintering and breeding grounds, irrespective of the variable climatic conditions along their migratory routes.

Download or read book Granivorous Birds in Ecosystems written by Jan Pinowski and published by Cambridge University Press. This book was released on 2012-03-29 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was first published in 1977. It deals with the importance of weed seed and grain-eating birds in natural and agricultural environments. These birds are to be found worldwide and are a component of man-made ecosystems where they are associated with man's main food crops. An analysis is made of their evolution and genetics, population dynamics, energy and food requirements, impact on ecosystems and control. Principles, procedures and basic data are presented that can be applied to the evaluation and control of pest species anywhere in the world. In this synthesis volume full use is made of the systems approach, the ecological and evolutionary aspects of the study are integrated. In linking the studies with fundamental work on bioenergetics, new insights are provided into the behavioural and applied aspects of granivory. Studies which encompass archaeological and anthropological investigations form a backcloth for the detailed interpretation of the population biology and bioenergetics of birds.
