Book Description
Skillful hunters beautiful in flight, Prairie Falcons inhabit the rocky cliffs of the American West. These raptors range from southern Canada and northern North Dakota to Baja California, Arizona, New Mexico, western and northern Texas, and southeastern Coahuila, Mexico. This is the first book for a wide audience devoted exclusively to the Prairie Falcon. Stanley Anderson and John Squires cover all aspects of the falcon's life history from mating and rearing young to hunting behaviors and the yearly migration cycle. They provide complete descriptive characteristics for identifying Prairie Falcons and also compare them to other raptors, especially the closely related Peregrine Falcon. In addition, the authors recount the long association of falcons with people, which may extend back as far as 2000 BC. They describe the practice of falconry from the Middle Ages until today. And they assess the threats to Prairie Falcons posed by human activities, from pesticide use and destruction of habitat to disruption of the breeding cycle by careless birdwatchers.

Book Description
Thus begins the tale by Stephen Bodio, a lover of birds and nature, of the incredible connection between man and birds of prey. Falconry can be traced back over four thousand years and, as Bodio says, “it is amazing that the practice did not die out soon afterward when its first adherents starved.” With a new introduction by Helen MacDonald, A Rage For Falcons not only shares the history of falconry, but shows the personal side in a way only Bodio can share. With masterful prose and breathtaking imagery, you not only understand how falconry has lasted, but why. As Bodio so appropriately notes in his introduction: “To understand falconry, you must understand the nature of the relationship between man and bird.” In A Rage For Falcons, Bodio explores this incredible relationship and how it has affected him as a person. Never has such a personal touch been put on a sport that has lasted generations, which many people still do not have a grasp of. That’s what makes Bodio so great. While his words may not convince you to take up the sport, will certainly open your eyes to appreciate a world unlike any other.

Book Description
Until recently, surprisingly little has been known about the biology and behavior of tropical forest raptors, including such basic aspects as diets, breeding biology, habitat requirements, and population ecology, information critical to the development of conservation efforts. The Peregrine Fund conducted a significant eight-year-long research program on the raptor species, including owls, in Tikal National Park in Guatemala to learn more about Neotropical birds of prey. Impressive and unprecedented in scale, this pioneering research also involved the development of new methods for detecting, enumerating, and studying these magnificent but often elusive birds in their forest home. Beautifully illustrated with photographs of previously little-known species, the resulting book is the most important single source for information on the lowland tropical forest raptor species found in Central America.Neotropical Birds of Prey covers twenty specific species in depth, including the Ornate Hawk-Eagle, the Barred Forest-Falcon, the Bat Falcon, and the Mexican Wood Owl, offering thorough synopses of all current knowledge regarding breeding biology and behavior, diet, habitat use, and spatial needs. Contributors to this landmark work also show how the populations fit together as a community with overlapping habitat and prey needs that can put them in competition with reptiles and mammalian carnivores as well, yet differ from one another in their nesting or feeding behaviors and population dynamics. The work's substantive original data offer interesting comparisons between tropical and temperate zone species, and provide a basis for establishing conservation measures based on firsthand research. Making available for the first time new data on the biology, ecology, behavior, and conservation of the majestic owls and raptors of the New World tropics, this book will appeal to a wide ornithological readership, especially the many raptor enthusiasts around the world.

Book Description
This monograph is the result of eight years of bibliographical and field research concerning several behavioural ecology aspects of the Palaearctic falcons. For a while, this book grew along with “The Lanner falcon” published in 2015 and revised in 2017. In both books the main aim was to provide a clear overview of the biology and ecology of these species. In fact in the last 20 years, the number of publications on falcons has grown tremendously and, in parallel, also those belonging to the so-called "grey literature". The number of people involved is also increased by including both academics and nature lovers. Many previously published books emphasized identification, and offered little insights on the behavioural and ecological aspects of the species. Very often, the research on behavioural ecology remains closed within the confines of academic community. By contrast, a multitude of basic data is scattered in countless articles published in local magazines. Many falcon species are easy to observe and study (such as kestrels) but others are more rare and localized. In order to understand the survival strategies adopted by this group of avian predators, it is necessary not to lose sight of the overall picture. This book tries to explain the different survival strategies by examining, through a few essential chapters, some crucial aspects for all species. The first chapter provides information on the genus Falco, its genetics, evolution and morphological peculiarities. The other chapters deal with reproductive strategies, competition, exploitation of resources, dispersal patterns, communication and sociality. One of the main objectives of this book is to produce an accessible but scholarly curated source of reference. By understanding the most common species, it is possible to provide a working framework for rarer, and especially threatened, falcon species.

Book Description
A ten year study began in 1972 in West Greenland to investigate the breeding biology of the peregrine falcon. Data on nesting gyrfalcons were also collected. Thirty-four peregrine nesting sites were examined in the 6050 km2 inland study area near Søndre Strømfjord. Limited research also centered in Disko Bugt and Frederikshåb. Peregrines were found nesting predominantly on high, south-facing cliffs, which overlooked large areas. The mean minimum distance between peregrine eyries was 7.7 km for the inland area (1972 and 1973) and 55 km for the coast (1974). Approximately 60 percent of the inland nesting sites were occupied each year. A ten-year average production of 1.90 young per occupied site and 2.78 young per successful site was determined. Lapland longspurs, snow buntings, wheatears, and redpolls comprised 90 percent of the peregrines diet. Raven nests and prey availability may be the most significant factor affecting falcon density. Addled peregrine eggs, eggshell fragments, and peregrine prey species were collected. Whole eggs averaged 14.3 ppm wet weight (305 ppm lipid weight ) DDE, while eggshell measurements showed a 16 percent thinning compared with pre-1940 eggs from Greenland. Prey species carried low levels of DDE. The peregrine population appears to be at a near critical contamination level, and a small increase in DDE level could contribute to a population decline. No indication of a decline has been observed during the study, and the population appears stable. The project banded 185 peregrines, from which 8 recoveries occurred. The recoveries suggest peregrines migrate south to winter in South America.
