Book Description
A gifted biologist's careful and beguiling study of why cuckoos have got away with tricking other birds into hatching and raising their young for thousands of years. The familiar call of the common cuckoo, “cuck-oo,” has been a harbinger of spring ever since our ancestors walked out of Africa many thousands of years ago. However, for naturalist and scientist Nick Davies, the call is an invitation to solve an enduring puzzle: how does the cuckoo get away with laying its eggs in the nests of other birds and tricking them into raising young cuckoos rather than their own offspring? Early observers who noticed a little warbler feeding a monstrously large cuckoo chick concluded the cuckoo's lack of parental care was the result of faulty design by the Creator, and that the hosts chose to help the poor cuckoo. These quaint views of bad design and benevolence were banished after Charles Darwin proposed that the cuckoo tricks the hosts in an evolutionary battle, where hosts evolve better defenses against cuckoos and cuckoos, in turn, evolve better trickery to outwit the hosts. For the last three decades, Davies has employed observation and field experiments to unravel the details of this evolutionary “arms race” between cuckoos and their hosts. Like a detective, Davies and his colleagues studied adult cuckoo behavior, cuckoo egg markings, and cuckoo chick begging calls to discover exactly how cuckoos trick their hosts. For birding and evolution aficionados, The Cuckoo is a lyrical and scientifically satisfying exploration of one of nature's most astonishing and beautiful adaptations.

Book Description
In this white-knuckled true story that is “as exciting as any action novel” (The New York Times Book Review), an astronomer-turned-cyber-detective begins a personal quest to expose a hidden network of spies that threatens national security and leads all the way to the KGB. When Cliff Stoll followed the trail of a 75-cent accounting error at his workplace, the Lawrence Berkeley National Laboratory, it led him to the presence of an unauthorized user on the system. Suddenly, Stoll found himself crossing paths with a hacker named “Hunter” who had managed to break into sensitive United States networks and steal vital information. Stoll made the dangerous decision to begin a one-man hunt of his own: spying on the spy. It was a high-stakes game of deception, broken codes, satellites, and missile bases, one that eventually gained the attention of the CIA. What started as simply observing soon became a game of cat and mouse that ultimately reached all the way to the KGB.

Book Description
The cinematographers and directors who shot film in wilderness areas at the turn of the 19th century are some of the unsung heroes of documentary film-making. Apart from severe weather conditions, these men and women struggled with heavy and cumbersome equipment in some of the most unforgiving locales on the planet. This groundbreaking study examines nature, wildlife and wilderness filming from all angles. Topics covered include the beginnings of film itself, the first attempts at nature and expedition filming, technical developments of the period involving cameras and lenses, and the role film has played in wilderness preservation. The individual contributions of major figures are discussed throughout, and a filmography lists hundreds of nature films from the period.

Book Description
The cuckoos are the most variable birds in social behavior and parental care: a few cuckoos are among the most social of all birds and rear their young in a common nest; most cuckoos are caring parents that rear their own young with some females laying a few eggs in the nests of others; while many cuckoo species are brood parasites who leave their eggs in the nests of other birds to rear, with their young maturing to kill their foster nestmates. In The Cuckoos, Robert B. Payne presents a new evolutionary history of the family based on molecular genetics, and uses the family tree to explore the origins and diversity of their behaviour. He traces details of the cuckoos' biology to their original sources, includes descriptions of previously unpublished field observations, and reveals new comparisons of songs showing previously overlooked cuckoo species. Lavishly illustrated with specially commissioned colour plates and numerous maps, halftones, and line drawings, The Cuckoos provides the most comprehensive and up-to-date account of this family yet available.
