Raptors


Book Description

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.




The Raptors of Arizona


Book Description

Thousands of birdwatchers come to Arizona each year seeking rare or intriguing species, and for those watching the skies the additional sighting of a bird of prey is a reward in itself. The Grand Canyon state boasts the most dramatic assortment of raptors in North America: hawks, eagles, falcons, kites, and owls, plus vultures and condors. Here can be found nearly all the raptor species of the continental United States and also established populations of species associated with Mexico, such as the Gray Hawk, Common Black-Hawk, Zone-tailed Hawk, and Whiskered Screech-Owl. Arizona's raptors are found in an unrivaled diversity of habitats, from saguaro cactus forests where tiny Elf Owls nest to the Vermilion Cliffs, where the gigantic California Condor was introduced in 1996. Yet many species live in habitats that are now jeopardized by degradation or development, making an understanding and appreciation of raptors crucial to their survival. The Raptors of Arizona brings together the knowledge and insights of 29 raptor and wildlife authorities who provide original information and syntheses on Arizona's 42 raptor species, with an emphasis on aspects of their natural history in Arizona. A chapter on each bird includes its description, a range map, and information on its distribution, habitat, life history, and status. Additional chapters cover conservation, habitats, where and when to watch raptors, and the sport of falconry. The book is enhanced by 42 full-color illustrations by Richard Sloan, one of the premier wildlife artists in North America, whose paintings were commissioned by the Arizona Wildlife Foundation specifically for this project. Co-published with the Arizona Game and Fish Department.




Hawk Ridge


Book Description

Was Caesar like the eagle because of his aquiline (from aquila, for “eagle” in Latin) nose, or does the eagle seem imperial because of his Caesar-like beak? Does the sharp vision of a “hawk-eyed” observer have any basis in nature? And what the heck is “kettling” to a bird-watcher, or, for that matter, a bird? Raptors have captured the imagination from time immemorial and have an especially rich history in Minnesota. The ancient peoples whose pictographs adorn the rock faces of Lake Superior's North Shore may well have witnessed the first hawk movements along Lake Superior—the same annual migration that today draws as many as twenty thousand people to Duluth's Hawk Ridge. These birds, passing through in astounding numbers, are among the hawks and accipiters, buteos and harriers, eagles and ospreys pictured and profiled in detail in this book. Written by one of Minnesota's best-known bird authorities, with images by one of the state's favorite illustrators, Hawk Ridge is as fun as it is informative. It introduces the state's raptors, from the rare visitor to the most familiar hawk, noting each species' signature traits—osprey wings, for instance, are crooked to help them catch fish; vultures urinate on their legs to cool themselves—and their nesting, breeding, and migrating habits. Did you know that Sharp-shinned Hawks banded at Hawk Ridge have been found throughout Central America and even into South America, and also, in midwinter, in Wisconsin? Laura Erickson offers a broad perspective (a bird's-eye view!), making sense of the raptor's role in the larger ornithological scheme. With descriptions of various species—and helpful distinctions between species, families, and orders—the book gives readers a clear idea of which raptors might be seen in Minnesota, when, where, and how often. It also includes a hawk migration primer that explains the movements that bring these birds in such awe-inspiring numbers to places like Hawk Ridge. Filled with curious facts and practical information for expert and amateur bird-watcher alike, the book is at once a guide to the hawks of Minnesota and a beautifully illustrated album of the most regal members of the avian kingdom.




Raptor's Ridge


Book Description

A professor and private detective is called in by an Oregon lawman for help with a high-profile murder . . . A mild-mannered college professor is an unlikely candidate to hunt down the killer of the town’s richest man and his movie star paramour. But because of a chance encounter years before, Max Blake, a former newspaper reporter-turned-professor and part-time private detective, is called in, and forced to form unusual and sometimes dodgy alliances, as he investigates the vicious killings with the city’s police chief. To make things worse, there’s a complicated history between Max and the chief—and the leading suspects are members of the city’s police force. The trail winds through the incredible mansion called Raptor’s Ridge and the streets and alleyways of Oregon’s state capital, and eventually spills into the beautiful but deadly High Desert near the town of John Day. When the killer is eventually cornered and violence explodes in unexpected ways, Max must use all of his wits and daring, plus a little bit of luck, to remain alive during a deadly night of terror . . . and eventual reckoning. Fans of the author’s Max Blake Westerns series will be delighted to discover this new and thoroughly modern Max—the great-great grandson and namesake of the legendary federal marshal who forms the basis of five previous novels.




Australian High Country Raptors


Book Description

Australian High Country Raptors covers raptor species that regularly breed in the high country above 600 metres, from Goulburn in New South Wales down to the hills outside Melbourne, Victoria. Author Jerry Olsen explores the nature of these striking animals that are classified as Accipitriformes (diurnal hawks, falcons, kites and eagles), Falconiformes and Strigiformes (nocturnal owls). Comparisons between these high country raptors and lower-elevation breeders are also provided, in addition to comparisons with raptors found overseas, especially from North America and Europe. The book begins with a description of habitats and vegetation types in the high country, and which raptors are likely to be seen in each habitat type. It continues with sections on finding and watching raptors, raptor identification, hunting styles, food, breeding and behaviour, and conservation. Appendices provide species accounts for diurnal breeding species in the high country, with basic information about their ecology, distribution and conservation, as well as detailed instructions about handling an injured or orphaned raptor. Illustrated throughout with photographs and drawings, Australian High Country Raptors offers readers a chance to look into the lives of Australia’s fascinating birds of prey.

Current Ornithology


Book Description

This edited series has three principal goals. The first is to provide information in a relatively concise way for researchers needing an over view of specific disciplines. The second is to provide an update on specific schools of thought, bringing together ideas from colleagues whose works often appear in a variety of journals. And the third is to stimulate and suggest directions for new research. Volume 6 continues the tradition established by the previous editor and editorial board in providing new information, updating our understanding of specific dis ciplines, and stimulating new research. In the first chapter, Randall Breitwisch examines mortality patterns and sex ratios in monogamous birds. He argues that there are many more components to measuring parental investment than are often re alized; our knowledge is weak in several areas. Understanding the evo lution of mating systems depends on better distinguishing the different intensities of natural selection that operate on males and females. Greg ory Butcher and Sievert Rohwer develop a framework for assessing the role of colorfulness in birds. They propose several hypotheses to test and advocate evaluating more than one hypothesis at a time. Future work on the evolution of distinctive coloration and of sexual and age dimorphism must take these ideas into account.







Migrating Raptors of the World
