In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum--reviving Darwin's own views--thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons--for the mere pleasure of it--is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

    In an unexpectedly zany adventure that took the author the equivalent of 3.3 times around the world, the result is a tale of theft, wartime atrocities, insane millionaires, intrigue in the Middle East, and skinny dipping.The Labrador Duck is often mentioned in the same breath as the Passenger Pigeon, the Dodo, and the Great Auk—great species that once roamed the planet. The Labrador Duck became extinct somewhere around 1875. It is the most enigmatic bird in North America, partially because it bred so far north that no record exists of its breeding, and partially because it became extinct almsot before we noted it was in decline. The Curse of the Labrador Duck chronicles Chilton's adventures while attempting to examine every stuffed specimen of the species, do genetic analysis of every Labrador Duck egg, and visit every North American site where the duck was shot.When Chilton began his investigation, there were thought to be about fifty specimens scattered amongst the museums of Europe, North America, and the Middle East. However, as his study advanced, it was clear that some specimens had been lost to war and theft, and others were secreted away in far-flung collections overseen by miserly curators. After travelling the equivalent of more than three times around the world, Chilton was able to examine what amounted to fifty-five specimens in total, although one turned out to be a forgery and several others had been tampered with by unscrupulous taxidermists. Regrettably, genetic analysis showed that none of the eggs attributed to the Labrador Duck were genuine, even those that had escaped the bombing of Dresden. On the positive side, the author earned numerous hangovers, swam naked in a glacier-fed stream, dined with Russian gangsters, and was able to narrowly avoid arrest in New York City.

    As in her bestseller Red-Tails in Love, Winn explores a once-hidden world in a series of interlocking narratives about the extraordinary denizens, human and animal, of an iconic American park.

    In Sightings, a collection of essays, bird watching forms the basis for observations spiritual and soulful, witty and wise. He describes his childhood ramblings in the silence of the Tennessee wilderness as feeling distinctly more spiritualthan the hard pews of his grandmother's church. Later in life, the presumed extinction and subsequent rediscovery of the Ivory-billed Woodpecker prompts a meditation on the nature of the sacred. Blessed with moments of beauty and the insight to recognize them as such, Keen translates the marvels of nature into the language of heart and soul.

    Home to one of the largest ornithological collections in the world, the Tring museum was full of rare bird specimens whose gorgeous feathers were worth staggering amounts of money to the men who shared Edwin's obsession: the Victorian art of salmon fly-tying. Once inside the museum, the champion fly-tier grabbed hundreds of bird skins--some collected 150 years earlier by a contemporary of Darwin's, Alfred Russel Wallace, who'd risked everything to gather them--and escaped into the darkness. Two years later, Kirk Wallace Johnson was waist high in a river in northern New Mexico when his fly-fishing guide told him about the heist. He was soon consumed by the strange case of the feather thief. What would possess a person to steal dead birds? Had Edwin paid the price for his crime? What became of the missing skins? In his search for answers, Johnson was catapulted into a years-long, worldwide investigation. The gripping story of a bizarre and shocking crime, and one man's relentless pursuit of justice, The Feather Thief is also a fascinating exploration of obsession, and man's destructive instinct to harvest the beauty of nature.

    For three men in particular, 1998 would become a grueling battle for a new North American birding record. Bouncing from coast to coast on frenetic pilgrimages for once-in-a-lifetime rarities, they brave broiling deserts, bug-infested swamps, and some of the lumpiest motel mattresses known to man. This unprecedented year of beat-the-clock adventures ultimately leads one man to a record so gigantic that it is unlikely ever to be bested. Here, prize-winning journalist Mark Obmascik creates a dazzling, fun narrative of the 275,000-mile odyssey of these three obsessives as they fight to win the greatest -- or maybe worst -- birding contest of all time.

    Being Mortal by Atul Gawande - A 20-minute Summary Inside this Instaread Summary: • Overview of the entire book• Introduction to the important people in the book• Summary and analysis of all the chapters in the book• Key Takeaways of the book• A Reader's Perspective Preview of this summary: Chapter 1 Gawande grew up in Ohio. His parents were immigrants from India and both were doctors. His grandparents stayed in India, and there were few older people in his neighborhood, so he had little experience with aging or death until he met his wife’s grandmother, Alice Hobson. Hobson was seventy-seven and living on her own in Virginia. She was a spirited widow who fixed her own plumbing and volunteered with Meals On Wheels. However, Hobson was losing strength and height steadily each year as her arthritis worsened.Gawande’s father enthusiastically adopted the customs of his new country, but he could not understand the way in which seniors were treated in the US. In India, the elderly were treated with great respect and lived out their lives with family.In the United States, Sitaram Gawande, Gawande’s grandfather, likely would have been sent to a nursing home like most of the elderly who cannot handle the basics of daily living by themselves. However, in India, Sitaram Gawande was able to live in his own home and manage his own affairs, with family constantly around him. He died at the age of one hundred and ten when he fell off a bus during a business trip.Until recently, most elderly people stayed with their families. Even as the nuclear family unit became predominant, replacing the multi-generational family unit, people cared for their elderly relatives. Families were large and one child, usually a daughter, would not marry in order to take care of the parents.This has changed in much of the world, where elderly people end up struggling to live alone, like Hobson, rather than living with dignity amid family, like Sitaram Gawande.One cause of this change can be found in the nature of knowledge. When few people lived to be very old, elders were honored. Their store of knowledge was greatly useful. People often portrayed themselves as older to command respect. Modern society’s emphasis on youth is a complete reversal of this attitude. Technological advances are perceived as the territory of the young, and everyone wants to be younger. High-tech job opportunities are all over the world, and young people do not hesitate to leave their parents behind to pursue them.In developed countries, parents embrace the concept of a retirement filled with leisure activities. Parents are happy to begin living for themselves once children are grown. However, this system only works for young, healthy retirees, but not for those who cannot continue to be independent. Hobson, for example, was falling frequently and suffering memory lapses. Her doctor did tests and wrote prescriptions, but did not know what to do about her deteriorating condition. Neither did her family… About the Author With Instaread Summaries, you can get the summary of a book in 30 minutes or less. We read every chapter, summarize and analyze it for your convenience.

    They have brains that are huge for their body size and exhibit an avian kind of eloquence. They mate for life and associate with relatives and neighbors for years. And because they often live near people—in our gardens, parks, and cities—they are also keenly aware of our peculiarities, staying away from and even scolding anyone who threatens or harms them and quickly learning to recognize and approach those who care for and feed them, even giving them numerous, oddly touching gifts in return. With his extraordinary research on the intelligence and startling abilities of corvids—crows, ravens, and jays—scientist John Marzluff teams up with artist-naturalist Tony Angell to tell amazing stories of these brilliant birds in Gifts of the Crow. With narrative, diagrams, and gorgeous line drawings, they offer an in-depth look at these complex creatures and our shared behaviors. The ongoing connection between humans and crows—a cultural coevolution—has shaped both species for millions of years. And the characteristics of crows that allow this symbiotic relationship are language, delinquency, frolic, passion, wrath, risk-taking, and awareness—seven traits that humans find strangely familiar. Crows gather around their dead, warn of impending doom, recognize people, commit murder of other crows, lure fish and birds to their death, swill coffee, drink beer, turn on lights to stay warm, design and use tools, use cars as nutcrackers, windsurf and sled to play, and work in tandem to spray soft cheese out of a can. Their marvelous brains allow them to think, plan, and reconsider their actions. With its abundance of funny, awe-inspiring, and poignant stories, Gifts of the Crow portrays creatures who are nothing short of amazing. A testament to years of painstaking research and careful observation, this fully illustrated, riveting work is a thrilling look at one of nature’s most wondrous creatures.

    Starting right at the beginning, with the eggs, his journey takes him from the incubator all the way to the airstrip, where he must attempt to teach the geese to fly as part of an ambitious scientific research initiative for the Max Planck Institute for Ornithology, which tracks animal migrations around the world. For the next eleven months, we follow the newly minted dad as he takes the goslings on daily swims in the lake, tracks them down when they go astray, and watches their personalities develop: feisty, churlish, and lovable. Packed with charm and humor, Papa Goose quickly draws us into the adventure as Gloria, Nemo, and the rest of the crew conquer land, water, and air.

    What is going on inside the head of a nightingale as it sings, and how does its brain improvise? How do desert birds detect rain hundreds of kilometers away? How do birds navigate by using an innate magnetic compass?Tracing the history of how our knowledge about birds has grown, particularly through advances in technology over the past fifty years, Bird Sense tells captivating stories about how birds interact with one another and their environment. More advanced testing methods have debunked previously held beliefs, such as female starlings selecting mates based on how symmetrical the male's plumage markings are. (Whereas females can discern the difference between symmetrical and asymmetrical markings, they are not very good at detecting small differences among symmetrically marked males!)Never before has there been a popular book about how intricately bird behavior is shaped by birds' senses. A lifetime spent studying birds has provided Tim Birkhead with a wealth of fieldwork experiences, insights, and a unique understanding of birds, all firmly grounded in science. No one who reads Bird Sense can fail to be dazzled by it.

    For example, I was once pinned down by a young lad who repeatedly asked me why I was hitting myself, when he knew full well that I had temporarily ceded hegemony over my hands and forearms. I tried to explain it to him, but he didn’t seem to comprehend. In retrospect, I can only conclude that my explanation was not articulate enough.To that end, I and Phil Plait have teamed up to create precisely 128 insults designed to weaken the resolve of aggressors, while educating them in their primary field of interest. Whether the person pummeling you is a student of mathematics or belles-lettres, we have the right words for the occasion.Zach WeinersmithPS: In the highly likely situation that the person pummeling you refuses to cease his aggression until he understands the meaning of the insult, we have also provided an appendix in which the insults are explained.
