Download or read book The Book of Eggs written by Mark E. Hauber and published by University of Chicago Press. This book was released on 2014-08-01 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Oology and Ralph s Talking Eggs written by Carrol L. Henderson and published by University of Texas Press. This book was released on 2007-10-15 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Most Perfect Thing written by Tim Birkhead and published by Bloomsbury Publishing USA. This book was released on 2016-04-12 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: A bird's egg is a nearly perfect survival capsule--an external womb--and one of natural selection's most wonderful creations. Shortlisted for the Royal Society Insight Investment Science Book Prize 2016.One of Forbes' Best Books About Birds and Birding in 2016. Renowned ornithologist Tim Birkhead opens this gripping story as a female guillemot chick hatches, already carrying her full quota of tiny eggs within her undeveloped ovary. As she grows into adulthood, only a few of her eggs mature, are released into the oviduct, and are fertilized by sperm stored from copulation that took place days or weeks earlier. Within a matter of hours, the fragile yolk is surrounded by albumen and the whole is gradually encased within a turquoise jewel of a shell. Soon the fully formed egg is expelled onto a rocky ledge, where it will be incubated for four weeks before a chick emerges and the life cycle begins again. THE MOST PERFECT THING is about how eggs in general are made, fertilized, developed, and hatched. Birkhead uses birds' eggs as wondrous portals into natural history, enlivened by the stories of naturalists and scientists, including Birkhead and his students, whose discoveries have advanced current scientific knowledge of reproduction.
