This book documents the paintings and drawings executed by Louis Agassiz Fuertes during the Field Museum of Natural History's seven-month expedition to Ethiopia (Abyssinia) in 1926-27. During that time Fuertes completed 70 field watercolors that illustrate 55 species of birds and four species of mammals. He also executed 34 pencil drawings, which illustrate 13 species of mammals and 11 species of birds, plus numerous miscellaneous sketches and small watercolors. This book identifies and describes the biology of all 69 species of birds and mammals illustrated by Fuertes and includes 32 color reproductions of Fuertes's watercolors that were published as a limited-edition album in 1930 by the Field Museum. The 60,000-word text provides brief summaries of all these species' ecology, behavior, and reproductive biology as well as information about their current populations and conservation status. A review of Fuertes's life, his influence on modern bird and wildlife art, and his participation in and artistic contributions to the Field Museum's Abyssinian Expedition is also included, as well as more than 250 bibliographic citations.

Spies in the Congo is the untold story of one of the most tightly-guarded secrets of the Second World War: America's desperate struggle to secure enough uranium to build its atomic bomb.The Shinkolobwe mine in the Belgian Congo was the most important deposit of uranium yet discovered anywhere on earth, vital to the success of the Manhattan Project. Given that Germany was also working on an atomic bomb, it was an urgent priority for the US to prevent uranium from the Congo being diverted to the enemy - a task entrusted to Washington's elite secret intelligence agents. Sent undercover to colonial Africa to track the ore and to hunt Nazi collaborators, their assignment was made even tougher by the complex political reality and by tensions with Belgian and British officials. A gripping spy-thriller, Spies in the Congo is the true story of unsung heroism, of the handful of good men -- and one woman -- in Africa who were determined to deny Hitler his bomb.

These include descriptions of range and status, field characters, voice, general habits, food, and breeding habits. Full bibliographies, acoustic references, and indexes complete this scholarly work of reference. This fourth volume in the series deals comprehensively with broadbills, pittas, larks, swallows and martins, wagtails, pipits and longclaws, cuckoo-shrikes, bulbuls, waxwings, dippers, wrens, accentors, and chats.

E. GWINNER! The phenomenon of bird migration with its large scale dimensions has attracted the attention of naturalists for centuries. Worldwide billions of birds leave their breeding grounds every autumn to migrate to areas with seasonally more favor able conditions. Many of these migrants travel only over a few hundred kilo meters but others cover distances equivalent to the circumference of the earth. Among these long-distance migrants are several billion birds that invade Africa every autumn from their West and Central Palaearctic breeding areas. In the Americas and in Asia the scope of bird migration is of a similar magnitude. Just as impressive as the numbers of birds are their achievements. They have to cope with the enormous energetic costs of long-distance flying. particularly while crossing oceans and deserts that do not allow replenishment of depleted fat reserves. They have to appropriately time the onset and end of migrations. both on a daily and annual basis. And finally. they have to orient their migratory movements in space to reach their species- or population-specific wintering and breeding grounds, irrespective of the variable climatic conditions along their migratory routes.
