Book Description
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.

Book Description
Before modern binoculars and cameras made it possible to observe birds closely in the wild, many people collected eggs as a way of learning about birds. Serious collectors called their avocation "oology" and kept meticulous records for each set of eggs: the bird's name, the species reference number, the quantity of eggs in the clutch, the date and location where the eggs were collected, and the collector's name. These documented egg collections, which typically date from the nineteenth and early twentieth centuries, now provide an important baseline from which to measure changes in the numbers, distribution, and nesting patterns of many species of birds. In Oology and Ralph's Talking Eggs, Carrol L. Henderson uses the vast egg collection of Ralph Handsaker, an Iowa farmer, as the starting point for a fascinating account of oology and its role in the origins of modern birdwatching, scientific ornithology, and bird conservation in North America. Henderson describes Handsaker's and other oologists' collecting activities, which included not only gathering bird eggs in the wild but also trading and purchasing eggs from collectors around the world. Henderson then spotlights sixty of the nearly five hundred bird species represented in the Handsaker collection, using them to tell the story of how birds such as the Snowy Egret, Greater Prairie Chicken, Atlantic Puffin, and Wood Duck have fared over the past hundred years or so since their eggs were gathered. Photos of the eggs and historical drawings and photos of the birds illustrate each species account. Henderson also links these bird histories to major milestones in bird conservation and bird protection laws in North America from 1875 to the present.

Book Description
The papers in this volume were presented at an international symposium, held in South Australia on September 8-10, 1983. The purpose of the meeting was to present the comparative physiology of gas exchange, water balance and energet ics of developing vertebrate embryos. contributions were invited from leading research workers in an attempt to represent the forefront of investigation of all vertebrate classes and to promote a broadly comparative approach to the study of embryonic physiology. These proceedings therefore reflect the current level of research activity focus ing on each group of vertebrates. While considerable expansion and specializa tion has occurred in the area of avian embryos over the last decade, work on reptilian embryos is less developed and that on fish and amphibians is still in its infancy. Although a great deal is known about respiration and metabolism in embryos of placental mammals, the physiology associated with the curious mode of development of monotreme and marsupial embryos has not been examined until recently. In this symposium. the well-studied vertebrate classes are repre sented primarily by specific research papers that document original work. These are balanced by more extensive reviews of the lesser known classes.
