Book Description
It is not often that a century of scholarly activity breaks conveniently into halves, but ornithology of the first half of the 20th century is clearly different from that of the second half. The break actually can be marked in 1949, with the appearance of Meyer and Schuz's Ornithologie ais Biologische Wissenschaft. Prior to this, ornithologists had tended to speak mostly to other ornithologists, experiments (the testing of hy potheses) were uncommon, and a concern for birds as birds was the dominant thread in our thinking. Subsequent to 1949, ornithologists have tended to become ever more professional in their pursuits and to incorporate protocols of experimental biology into their work; more importantly perhaps, they have begun to show a concern for birds as agencies for the study of biology. Many of the most satisfying of recent ornithological studies have come from reductionist research ap proaches, and have been accomplished by specialists in such areas as biochemistry, ethology, genetics, and ecology. A great many studies routinely rely on statistical hypothesis testing, allowing us to come to conclusions unmarred by wishful thinking. Some of us are ready to tell the world that we are a "hard" science, and perhaps that time is not so very far off for most of us. Volume 2 examines several solid examples of late 20th-century ornithology.

Book Description
Harriers are a charismatic group of birds of prey with a worldwide distribution that have long fascinated bird watchers and scientists. Here for the first time the biology of the world's harriers is treated within one over, in readily accessible language. There are detailed comparisons of northern and southern species, descriptions of mating systems and population dynamics life histories, and insights into the selection pressures shaping the birds' life histories. The author addresses such questions as how females choose partners against their apparent self- interest, how they adjust to prevailing circumstances to produce the perfect clutch size, and what underlies variations in size dimorphism and copulation patterns. New information resulting from a DNA examination of the group reveals three new harrier species and allows construction of a new phylogeny of the harriers. The author's twin brother brings the book to life by fine original line drawings of these impressive birds. It will be a treat for all raptor biologists, amateur raptophiles, and behavioral ecologists interested in birds of prey.

Book Description
As evidenced by the incredible success of Helen MacDonald's H is for Hawk, and the legions of fans of Pale Male, the incredible red-tailed hawk of 5th avenue, we are full of rapture for raptors. James Macdonald Lockhart, is among the many who have sought out these incredible birds, and in this lyrical work of natural history he seeks out 15 different raptors, in 15 different landscapes across England: a journey in search of raptors, a journey through the birds and into their worlds. Raptors are by nature scarce and extremely elusive. Of Pandionidae (osprey), Accipitridae (broad-winged harrier, eagle, buzzard, red kite) and Falconidae (peregrine, sparrowhawk etc.) only widespread buzzards, kestrels and kites are easily seen. Lockhart follows loosely the trail of 19th-century Scottish naturalist and artist William MacGillivray (1796-1852), As Philip Hoare wrote of it, James MacDonald Lockhart puts the rapture back in the raptor. This is in-the-moment writing, raw in beak and claw. With its gorgeously felt sense of life and place, Raptor rips at its words, turning them into exquisite portraits of the utter wild, shaping soaring, obsessive beauty out of the British landscape and its imperial birds"
