Download or read book Orientation in Birds written by P. Berthold and published by Birkhäuser. This book was released on 2013-03-08 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: If it is true that science proceeds from a romantic through a scientific to a technological stage, then research on bird orientation is certainly on its move from its first to its second grade, and recent developments in radiotelemetry and satellite tracking of migrating birds might already indicate the advent of the third stage. At this juncture, Orientation in Birds is a timely account. Even though the study of animal migration in general, and bird navigation in particular, has produced a literature of impressive proportions, the threads provided by the plethora of research papers, review articles and symposiums volumes have not yet been knitted into a theoretical fabric. This is partly due to our still incomplete understanding of fundamen tal topics in avian navigation. The answer to the most intriguing question of how a bird displaced to "unknown" territory finds its way back home is as obscure now as it was a few decades ago. Whether and how birds solve this problem by using far ranging grid-maps or more local familiar-area maps, as has been proposed off and on, is still a matter of heated debates. These debates frequently center around provocative hypotheses - let alone the question about the physical (topographic, magnetic, infrasonic, olfactory) parameters which might constitute such maps.

Download or read book Paleogene Fossil Birds written by Gerald Mayr and published by Springer Science & Business Media. This book was released on 2009-04-21 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present book the Paleogene fossil record of birds is detailed for the first time on a worldwide scale. I have developed the idea for such a project for several years, and think that it is an appropriate moment to present a summary of our c- rent knowledge of the early evolution of modern birds. Meanwhile not only is there a confusing diversity of fossil taxa, but also significant progress has been made concerning an understanding of the higher-level phylogeny of extant birds. Hypotheses which were not considered even a decade ago are now well supported by independent analyses of different data. In several cases these group together morphologically very different avian groups and allow a better understanding of the mosaic character distribution found in Paleogene fossil birds. The book aims at bringing some of this information together, and many of the following data are based on first-hand examination of fossil specimens.

Download or read book Birds in Winter written by Roger F. Pasquier and published by Princeton University Press. This book was released on 2019-08-13 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: How birds have evolved and adapted to survive winter Birds in Winter is the first book devoted to the ecology and behavior of birds during this most challenging season. Birds remaining in regions with cold weather must cope with much shorter days to find food and shelter even as they need to avoid predators and stay warm through the long nights, while migrants to the tropics must fit into very different ecosystems and communities of resident birds. Roger Pasquier explores how winter affects birds’ lives all through the year, starting in late summer, when some begin caching food to retrieve months later and others form social groups lasting into the next spring. During winter some birds are already pairing up for the following breeding season, so health through the winter contributes to nesting success. Today, rapidly advancing technologies are enabling scientists to track individual birds through their daily and annual movements at home and across oceans and hemispheres, revealing new and unexpected information about their lives and interactions. But, as Birds in Winter shows, much is visible to any interested observer. Pasquier describes the season’s distinct conservation challenges for birds that winter where they have bred and for migrants to distant regions. Finally, global warming is altering the nature of winter itself. Whether birds that have evolved over millennia to survive this season can now adjust to a rapidly changing climate is a problem all people who enjoy watching them must consider. Filled with elegant line drawings by artist and illustrator Margaret La Farge, Birds in Winter describes how winter influences the lives of birds from the poles to the equator.

Download or read book Toucans Barbets and Honeyguides written by Lester Short and published by Oxford University Press. This book was released on 2001-11-08 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers in unmatched detail the life history, relationships, biology, and conservation of all the world's toucans, barbets, and honeyguides. These number 133 species, found in tropical regions around the world. The toucans are especially well-known because of their dramatic bills and their association with the Amazon rainforest. The colour plates, painted by well- known US artist Albert Earl Gilbert, are probably the best paintings of these birds ever produced.
