Flight Strategies of Migrating Hawks by Paul Kerlinger Pdf

Hawks fly at very high altitudes, sometimes over water, and thus their flight behavior and migration patterns are extremely difficult to study. Now, based on nearly ten years of research, this book provides the most complete analysis to date of how hawks migrate. Paul Kerlinger has employed both direct observations and radar techniques to obtain a much more accurate understanding of the migratory behavior of hawks and the "decisions" they make in flight. And, he has integrated data on the flight behavior of raptors in general with information about their ecology, physiology, evolution, and nonmigratory behavior. Kerlinger begins with an overview, discussing ecology and geography, research methods, natural history, and evolution, and atmospheric structure. He then addresses specific aspects of flight behavior: aerodynamics, morphology, mechanics, direction, altitude, flocking, water crossing, speed selection, daily distance traveled, and flight strategies. Kerlinger describes each aspect of behavior quantitatively, testing mechanistic hypotheses. In conclusion, he examines how migrants integrate these behavioral components. Throughout the text he draws comparisons between the migratory flight behavior of hawks and that of other taxa. By means of such comparisons, researchers can gain insight into the selective pressures that shape the behavior of migrant species.

Migration Strategies of Birds of Prey in Western Palearctic by Michele Panuccio,Ugo Mellone,Nicolantonio Agostini Pdf

Given their roles in the ecosystem, raptors are widely considered the flagship or umbrella species among birds. Most species undertake a seasonal journey that is impressive because of the length, and the imposing natural barriers such as deserts and seas that they fly over. The migration of birds of prey has unique characteristics in the animal world because of their morphology and flight style. The flying path of Afro-Palearctic migrants between breeding and wintering grounds is determined by several factors such as morphology of the birds, geography, behavioural adaptations. The book analyses the migration patterns of raptors along the Afro-Palearctic migratory system, and summarizes the recent research on these top predator species. Behavioural adaptations such as the importance of social interactions and the modulation of the different flight styles as well as ecological interactions with the encountered environment and weather conditions en route are described in the book. Moreover, the impact of climate change on the migratory behaviour and key conservation issues are discussed. The book provides an overview of the migratory characteristics and flyway patterns of all European raptors species and also some Asian ones. These chapters have been written by some of the most important raptor specialists, giving a complete picture of the different migration strategies on the basis of both traditional methods and new technologies.

Migrating Raptors of the World by Keith L. Bildstein Pdf

"Keith L. Bildstein has studied migrating raptors on four continents and directs the conservation science program at Hawk Mountain Sanctuary, Pennsylvania, the world's first refuge for migratory birds of prey. In this book, he details the stories and successes of twelve of the world's most important raptor-viewing spots, among them Cape May Point, New Jersey; Veracruz, Mexico; Kekoldi, Costa Rica; the Strait of Gibralter, Spain; and Elat, Israel."--BOOK JACKET.

Raptors by Keith L. Bildstein Pdf

Raptors are formally classified into five families and include birds—such as eagles, ospreys, kites, true hawks, buzzards, harriers, vultures, and falcons—that are familiar and recognized by many observers. These diurnal birds of prey are found on every continent except Antarctica and can thrive in seemingly inhospitable spots such as deserts and the tundra. They have powerful talons and hooked beaks for cutting and tearing meat, and keen binocular vision to aid in their hunting prowess. Because of their large size, distinctive feeding habits, and long-distance flight patterns, raptors intrigue humans and have been the subject of much general interest as well as extensive scientific research. Keith L. Bildstein has watched and studied raptors on five continents and is well prepared to explain their critical importance, not only as ecological entities but also as inspirational tokens across natural and human-dominated landscapes. His book offers a comprehensive and accessible account of raptors, including their evolutionary history, their relationships to other groups of birds, their sensory abilities, their general natural history, their breeding ecology and feeding behavior, and threats to their survival in a human-dominated world. Biologically sound but readable, Raptors is a nontechnical overview of this captivating group. It will allow naturalists, birders, hawk-watchers, science educators, schoolchildren, and the general public, along with new students in the field of raptor biology, to understand and appreciate these birds, and in so doing better protect them.

Flight Identification of Raptors of Europe, North Africa and the Middle East by Dick Forsman Pdf

Raptors are notoriously hard to identify, even if seen well, and represent perhaps the toughest of all ID challenges for birders. This book is the ultimate flight-identification guide for the raptors of the Western Palaearctic, covering Europe, North Africa, the Middle East (including Arabia) to Central Asia. It provides identification information for all 60 species that regularly occur in the region, to subspecific level. The text covers every plumage and age in detail, with each species account accompanied by a range of photographs covering all the principal plumages. Based on this stunning photographic coverage, most of which has never been published before, this book represents a landmark in bird identification books and a major work for all raptor enthusiasts.

Gatherings of Angels by Kenneth P. Able Pdf

The migration of birds has forever amazed and confounded onlookers. How do birds find their way to their destinations? How do they withstand the dangers and rigors of long-distance flight? The survival of migrant birds is increasingly threatened by environmental degradation and manmade hazards; their protection is more critical than ever. Gatherings of Angels offers first-hand accounts by leading experts who convey the beauty and excitement of migration while communicating important messages about avian conservation. The book features twenty-four pages of stunning color photographs with additional black-and-white photographs throughout.Two chapters of background information on migration precede chapters that focus on different species or groups of birds and the localities essential to their survival--from the spring flights of songbirds across the Gulf of Mexico to the massing of sandhill cranes on the Platte River. The authors discuss the timing of migrant travel; the routes followed; and the concentration of birds in stop-over sites, locations that must be preserved if they are to have secure resting spots with fresh water and ample food to fuel their journey.
