Book Description
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.

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
A “well-written, engaging detective story” (Kirkus Reviews, starred review) about a rogue who trades in rare birds and their eggs—and the wildlife detective determined to stop him. On May 3, 2010, an Irish national named Jeffrey Lendrum was apprehended at Britain’s Birmingham International Airport with a suspicious parcel strapped to his stomach. Inside were fourteen rare peregrine falcon eggs snatched from a remote cliffside in Wales. So begins a “vivid tale of obsession and international derring-do” (Publishers Weekly), following the parallel lives of a globe-trotting smuggler who spent two decades capturing endangered raptors worth millions of dollars as race champions—and Detective Andy McWilliam of the United Kingdom’s National Wildlife Crime Unit, who’s hell bent on protecting the world’s birds of prey. “Masterfully constructed” (The New York Times) and “entertaining and illuminating” (The Washington Post), The Falcon Thief will whisk you away from the volcanoes of Patagonia to Zimbabwe’s Matobo National Park, and from the frigid tundra near the Arctic Circle to luxurious aviaries in the deserts of Dubai, all in pursuit of a man who is reckless, arrogant, and gripped by a destructive compulsion to make the most beautiful creatures in nature his own. It’s a story that’s part true-crime narrative, part epic adventure—and wholly unputdownable until the very last page.
