This is the definitive natural history of the spectacularly beautiful tropical birds known as the trogons, a family that includes the legendary Resplendent Quetzal, the sacred bird of the ancient Mayans and Aztecs. A collaboration between renowned ornithologist Joseph Forshaw and eminent bird artist Albert Gilbert, Trogons combines science and art to create an unprecedented picture of a threatened bird family. Forshaw's text provides the most authoritative and comprehensive account of the trogons ever written, and Gilbert's stunning paintings are the first to accurately depict all species of trogons in their natural habitats and true colors. The book's detailed synthesis of current knowledge about the trogons is enriched by Forshaw's personal field observations in the tropical rainforests of Southeast Asia, Africa, and the Americas, while Gilbert's meticulous artwork is based on fieldwork in the same areas. With its large format, more than 40 full-color plates, and state-of-the-art five-color printing, this limited-edition book promises to become a classic and a collector's item. Despite their long association with human culture, trogons remain poorly known. Much of the existing ecological information comes from studies of a few neotropical species undertaken in the 1930s and 1940s by Alexander Skutch in Costa Rica and Guatemala, and more recent field studies of the Elegant Trogon at the northern extremity of the range. There have been longstanding uncertainties about the relations and origins of trogons. Kingfishers and their allies have often been nominated as the trogons' closest allies and a New World origin was assumed because most trogon species are now found in the neotropics. However, recent studies have supported placing trogons in a separate order--Trogoniformes--with possible affinities to the African mousebirds, and there is some evidence for an Old World origin. At a time when researchers and fieldworkers are showing increasing interest in the trogons, and when tropical forests, the home of most trogon species, are threatened by logging and land clearing, this book is intended to not only summarize and advance knowledge about trogons but also to draw attention to the urgent need to protect these magnificent birds by safeguarding the habitats so critical to their continued survival. Trogons is an essential volume for libraries, birders, conservationists, ornithologists, eco-tourists, and collectors of fine bird books.

Example in this ebook THE CURASSOW. An interesting race of birds, known as the Curassows, has its range throughout that part of South America, east of the Andes Mountain range and north of Paraguay. All the species are confined to this region except one, which is found in Central America and Mexico. This is the bird of our illustration (Crax globicera). The Curassows belong to the order of Gallinaceous birds and bear the same relation to South America that the pheasants and grouse bear to the Old World. They are in every respect the most important and the most perfect game birds of the district which they inhabit. In all there are twelve species placed under four genera. As the hind toes of the feet are placed on a level with the others they resemble the pigeon and are unlike many of the other gallinaceous birds. The Curassows are very large and rather heavy birds and some of them are larger than our turkey. They have short wings and a strong bill. At the base of the upper mandible and on the upper side there is a large tubercle-like excrescence which is of a yellow color and quite hard. Upon the head there is a gracefully arched crest of feathers which is made of curled feathers, the tips of which are white in some of the species. This crest can be lowered or raised at the will of the bird. The plumage of the species illustrated is a beautiful and velvety black, except the white on the lower portion of the body. It is said that their motions are much more graceful than are those of our common domestic turkey. “They live in small flocks, and are arboreal in their habits, only occasionally descending to the ground, while roosting and building their nests on the branches of trees.” The nests are large and made of twigs and willowy branches held in place by the stems of grasses, which are neatly interwoven between them. The nest is lined with down, feathers and leaves. It is said that they are easily domesticated and that in some parts of South America they may be found in tame flocks around the homes of the planters. One authority states that at about the beginning of the present century a large number of Curassows were taken from Dutch Guiana to Holland, where they became thoroughly domesticated, breeding as readily as any other kind of domestic poultry. Though a tropical bird, it would seem that they might be acclimatized. They would certainly form a valuable addition to the list of our farm fowls, for their flesh is said to be “exceedingly white and delicate.” The female is not as large as the male and is usually reddish in color. Their food consists almost entirely of fruit and insects. About the middle of the eighteenth century Eleazar Albin wrote “A Natural History of Birds,” in which he gives a very interesting account of the Curassow and an excellent illustration of the bird. He says: “I took a pourtray of this bird at Chelmsford in Essex; it was very tame and sociable, eating and drinking with any company. The Cock I had of a man from the West Indies. They are generally brought from Carasow, from whence they take their Name. They are called by the Indians Tecuecholi, Mountain-Bird or American Pheasant.” To be continue in this ebook

When and where did the ancestors of modern birds evolve? What enabled them to survive the meteoric impact that wiped out the dinosaurs? How did these early birds spread across the globe and give rise to the 10,600-plus species we recognise today ― from the largest ratites to the smallest hummingbirds? Based on the latest scientific discoveries and enriched by personal observations, The Ascent of Birds sets out to answer these fundamental questions. The Ascent of Birds is divided into self-contained chapters, or stories, that collectively encompass the evolution of modern birds from their origins in Gondwana, over 100 million years ago, to the present day. The stories are arranged in chronological order, from tinamous to tanagers, and describe the many dispersal and speciation events that underpin the world's 10,600-plus species. Although each chapter is spearheaded by a named bird and focuses on a specific evolutionary mechanism, the narrative will often explore the relevance of such events and processes to evolution in general. The book starts with The Tinamou’s Story, which explains the presence of flightless birds in South America, Africa, and Australasia, and dispels the cherished role of continental drift as an explanation for their biogeography. It also introduces the concept of neoteny, an evolutionary trick that enabled dinosaurs to become birds and humans to conquer the planet. The Vegavis's Story explores the evidence for a Cretaceous origin of modern birds and why they were able to survive the asteroid collision that saw the demise not only of dinosaurs but of up to three-quarters of all species. The Duck's Story switches to sex: why have so few species retained the ancestral copulatory organ? Or, put another way, why do most birds exhibit the paradoxical phenomenon of penis loss, despite all species requiring internal fertilisation? The Hoatzin's Story reveals unexpected oceanic rafting from Africa to South America: a stranger-than-fiction means of dispersal that is now thought to account for the presence of other South American vertebrates, including geckos and monkeys. The latest theories underpinning speciation are also explored. The Manakin’s Story, for example, reveals how South America’s extraordinarily rich avifauna has been shaped by past geological, oceanographic and climatic changes, while The Storm-Petrel’s Story examines how species can evolve from an ancestral population despite inhabiting the same geographical area. The thorny issue of what constitutes a species is discussed in The Albatross's Story, while The Penguin’s Story explores the effects of environment on phenotype ― in the case of the Emperor penguin, the harshest on the planet. Recent genomic advances have given scientists novel approaches to explore the distant past and have revealed many unexpected journeys, including the unique overland dispersal of an early suboscine from Asia to South America (The Sapayoa’s Story) and the blackbird's ancestral sweepstake dispersals across the Atlantic (The Thrush’s Story). Additional vignettes update more familiar concepts that encourage speciation: sexual selection (The Bird-of-Paradise's Story); extended phenotypes (The Bowerbird's Story); hybridisation (The Sparrow's Story); and 'great speciators' (The White-eye's Story). Finally, the book explores the raft of recent publications that help explain the evolution of cognitive skills (The Crow's Story); plumage colouration (The Starling's Story); and birdsong (The Finch's Story)
