This guide provides species-to-species accounts of the nesting habits of each bird, the types of nests they build, and a summary of their breeding biology (laying months, clutch size, egg size, incubation and nestling periods).
From the brilliantly green and glossy eggs of the Elegant Crested Tinamou—said to be among the most beautiful in the world—to the small brown eggs of the house sparrow that makes its nest in a lamppost and the uniformly brown or white chickens’ eggs found by the dozen in any corner grocery, birds’ eggs have inspired countless biologists, ecologists, and ornithologists, as well as artists, from John James Audubon to the contemporary photographer Rosamond Purcell. For scientists, these vibrant vessels are the source of an array of interesting topics, from the factors responsible for egg coloration to the curious practice of “brood parasitism,” in which the eggs of cuckoos mimic those of other bird species in order to be cunningly concealed among the clutches of unsuspecting foster parents. The Book of Eggs introduces readers to eggs from six hundred species—some endangered or extinct—from around the world and housed mostly at Chicago’s Field Museum of Natural History. Organized by habitat and taxonomy, the entries include newly commissioned photographs that reproduce each egg in full color and at actual size, as well as distribution maps and drawings and descriptions of the birds and their nests where the eggs are kept warm. Birds’ eggs are some of the most colorful and variable natural products in the wild, and each entry is also accompanied by a brief description that includes evolutionary explanations for the wide variety of colors and patterns, from camouflage designed to protect against predation, to thermoregulatory adaptations, to adjustments for the circumstances of a particular habitat or season. Throughout the book are fascinating facts to pique the curiosity of binocular-toting birdwatchers and budding amateurs alike. Female mallards, for instance, invest more energy to produce larger eggs when faced with the genetic windfall of an attractive mate. Some seabirds, like the cliff-dwelling guillemot, have adapted to produce long, pointed eggs, whose uneven weight distribution prevents them from rolling off rocky ledges into the sea. A visually stunning and scientifically engaging guide to six hundred of the most intriguing eggs, from the pea-sized progeny of the smallest of hummingbirds to the eggs of the largest living bird, the ostrich, which can weigh up to five pounds, The Book of Eggs offers readers a rare, up-close look at these remarkable forms of animal life.
The Roberts Bird Guide (2nd Edition) has gone to great trouble to concentrate on, and illustrate, difficult-to-identify species and family groups such as raptors, warblers, cisticolas and waders. Special attention has been given to make sure there is far greater coverage of male-female differences and there are also many more juvenile illustrations. Unlike all previously published southern African bird guides, this new edition will be scattered with informative photographs that are incorporated in the text pages and each plate illustration is augmented with an introduction. Apart from the approximately 240 plate spreads, the guide also has 12 photographic and illustrated double spreads that show head enlargements and other details. Plates are annotated far more definitively than other guides - highlighting key identification features, especially for difficult-to-identify species. Plates are richly illustrated with vignettes, which will make any birding experience more informative.
Revealing fascinating insights into the mysterious lives of birds native to the mother continent, this remarkable guide exhibits the many vibrantly colorful species found in the South African bush. Providing an in-depth discourse on all aspects of bird life--detailing their myriad forms, survival strategies in a harsh landscape, breeding and feeding behaviors, movements, migrations, preferred habitat, unique behavioral patterns, and vocalizations--this comprehensive manual also expertly advises on how to easily and accurately identify each individual species. Populated with more than 900 brilliantly vivid photographs and exhaustively researched to fill the gap in existing literature and field guides, this essential reference will delight nature lovers, tourists, birdwatchers, and bush lovers alike.
Examines the nests that birds build around the world, including illustrations of each nest type's construction, descriptions of the materials and techniques used during the process, and case studies on specific birds' habitats.
With expanded text and even larger colour illustrations, this guide covers every species and every plumage you will see, with detailed information on identification, habitat and voice.
