Birds play a prominent role in attracting visitors, too. The shimmering quetzals, gaudy macaws, and comical toucans only begin to hint at the impressive avian diversity to be found throughout this small country."--from the Introduction This is the one field guide the novice or experienced birder needs to identify birds in the field in the diverse habitats found in Costa Rica. It features descriptions and illustrations of more than 820 resident and neotropical migrant species found in Costa Rica, all in a compact, portable, user-friendly design. The detailed full-color illustrations show identifying features--including plumage differences among males, females, and juveniles--and views of birds in flight wherever pertinent. Additional features of this all-new guide include: o 166 original color plates depicting more than 820 species. o Concise text that describes key field marks for positive identification, as well as habitat, behavior, and vocalizations. o Range maps and texts arranged on opposing pages from illustrations for quick, easy reference. o The most up-to-date bird list for Costa Rica. o A visual guide to the anatomical features of birds with accompanying explanatory text. o Quick reference to vultures and raptors in flight.

    There they began a strenuous and thrilling hundred-day field trip around the edge of the continent. Part travelogue, part epic natural adventure, their richly illustrated record is "the superlatively good product of ideal circumstances" (Chicago Sunday Tribune).

    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.

    They are also astonishingly diverse in their shapes, patterns, textures, and colors—in nature’s fashion show, they are the haute couture of marine life.This collection of more than 250 remarkable images is the result of seven years of painstaking fieldwork across the Pacific Ocean, using photographic techniques that Middleton developed to capture these extremely fragile creatures on camera. She also provides short essays that examine the place these invertebrates occupy on the tree of life, their vast array of forms, and their lives in the ocean. Scientist Bernadette Holthuis contributes profiles describing each species, many of them for the first time. Middleton’s book is a stunning new view of nature that harmoniously combines art and science.

    In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age. Part paleontological adventure and part memoir, Twilight of the Mammoths presents in detail internationally renowned paleoecologist Paul Martin's widely discussed and debated "overkill" hypothesis to explain these mysterious megafauna extinctions. Taking us from Rampart Cave in the Grand Canyon, where he finds himself "chest deep in sloth dung," to other important fossil sites in Arizona and Chile, Martin's engaging book, written for a wide audience, uncovers our rich evolutionary legacy and shows why he has come to believe that the earliest Americans literally hunted these animals to death.As he discusses the discoveries that brought him to this hypothesis, Martin relates many colorful stories and gives a rich overview of the field of paleontology as well as his own fascinating career. He explores the ramifications of the overkill hypothesis for similar extinctions worldwide and examines other explanations for the extinctions, including climate change. Martin's visionary thinking about our missing megafauna offers inspiration and a challenge for today's conservation efforts as he speculates on what we might do to remedy this situation—both in our thinking about what is "natural" and in the natural world itself.

    There were bacteria in volcanic hydrothermal vents on the ocean floor, single-celled algae in Antarctic ice floes, and fungi in the cooling pools of nuclear reactors.But might there be life stranger than the most extreme extremophile? Might there be, somewhere, another kind of life entirely? In fact, scientists have hypothesized life that uses ammonia instead of water, life based not in carbon but in silicon, life driven by nuclear chemistry, and life whose very atoms are unlike those in life we know. In recent years some scientists have begun to look for the tamer versions of such life on rock surfaces in the American Southwest, in a “shadow biosphere” that might impinge on the known biosphere, and even deep within human tissue. They have also hypothesized more radical versions that might survive in Martian permafrost, in the cold ethylene lakes on Saturn’s moon Titan, and in the hydrogen-rich atmospheres of giant planets in other solar systems. And they have imagined it in places off those worlds: the exotic ices in comets, the vast spaces between the stars, and—strangest of all—parallel universes.Distilling complex science in clear and lively prose, David Toomey illuminates the research of the biological avant-garde and describes the workings of weird organisms in riveting detail. His chapters feature an unforgettable cast of brilliant scientists and cover everything from problems with our definitions of life to the possibility of intelligent weird life. With wit and understanding that will delight scientists and lay readers alike, Toomey reveals how our current knowledge of life forms may account for only a tiny fraction of what’s really out there.

    What they don't know is that without algae, none of us would exist. There are as many algae on Earth as stars in the universe, and they have been essential to life on our planet for eons. Algae created the Earth we know today, with its oxygen-rich atmosphere, abundant oceans, and coral reefs. Crude oil is made of dead algae, and algae are the ancestors of all plants. Today, seaweed production is a multi-billion dollar industry, with algae hard at work to make your sushi, chocolate milk, beer, paint, toothpaste, shampoo, and so much more. In Slime we'll meet the algae innovators working toward a sustainable future: from seaweed farmers in South Korea, to scientists using it to clean the dead zones in our waterways, to the entrepreneurs fighting to bring algae fuel and plastics to market. With a multitude of lively, surprising science and history, Ruth Kassinger takes listeners on an around-the-world, behind-the-scenes, and into-the-kitchen tour. Whether you thought algae was just the gunk in your fish tank or you eat seaweed with your oatmeal, Slime will delight and amaze with its stories of the good, the bad, and the up-and-coming.

    Why does the chestnut-sided warbler sing one song before dawn and another after sunrise? Why does the brown thrasher have a repertoire of two thousand songs when the chipping sparrow has only one? And how is the hermit thrush able to sing a duet with itself, producing two sounds simultaneously to create its beautiful, flutelike melody?Stap's lucid prose distills the complexities of the study of birdsong and unveils a remarkable discovery that sheds light on the mystery of mysteries: why young birds in the suborder oscines -- the "true songbirds" -- learn their songs but the closely related suboscines are born with their songs genetically encoded. As the story unfolds, Stap contemplates our enduring fascination with birdsong, from ancient pictographs and early Greek soothsayers, who knew that bird calls represented the voices of the gods, to the story of Mozart's pet starling.In a modern, noisy world, it is increasingly difficult to hear those voices of the gods. Exploring birdsong takes us to that rare place -- in danger of disappearing forever -- where one hears only the planet's oldest music.

    To find a meal, the female bolas spider releases pheromones that mimic a female moth, luring male moths into her sticky lasso web. The Glyptapanteles wasp injects a caterpillar with her young, which feed on the victim, erupt out of it, then mind-control the poor (and somehow still living) schmuck into protecting them from predators.These are among the curious critters of The Wasp That Brainwashed the Caterpillar, a jaunt through evolution’s most unbelievable, most ingenious solutions to the problems of everyday life, from trying to get laid to finding food. Join Wired science writer Matt Simon as he introduces you to the creatures that have it figured out, the ones that joust with their mustaches or choke sharks to death with snot, all in a wild struggle to survive and, of course, find true love.

    At every turn, it seems, living things are trying to eat us, poison us, use our bodies as their homes, or have us spread their eggs. In Mother Nature Is Trying to Kill You, Riskin is our guide through the natural world at its most gloriously ruthless.Using the seven deadly sins as a road map, Riskin offers dozens of jaw-dropping examples that illuminate how brutal nature can truly be. From slothful worms that hide in your body for up to thirty years to wrathful snails with poisonous harpoons that can kill you in less than five minutes to lustful ducks that have orgasms faster than you can blink, these fascinating accounts reveal the candid truth about “gentle” Mother Nature’s true colors.Riskin’s passion for the strange and his enthusiastic expertise bring Earth’s most fascinating flora and fauna into vivid focus. Through his adventures— which include sliding on his back through a thick soup of bat guano just to get face-to-face with a vampire bat, befriending a parasitic maggot that has taken root on his head, and coming to grips with having offspring of his own—Riskin makes unexpected discoveries not just about the world all around us but also about the ways this brutal world has shaped us as humans and what our responsibilities are to this terrible, wonderful planet we call home.

    Explorer and noted bird expert Tim Gallagher is no stranger to the obsession for adventure. In the early 2000s, Gallagher rediscovered the legendary Ivory-billed Woodpecker—which most scientists believed had been extinct for sixty years—causing an international stir.Now, in Imperial Dreams, Gallagher once again hits the trail, with a “natural treasure” map of sightings of the Imperial bestowed on him by a friend on his deathbed. Charged with continuing the quest of a line of distinguished naturalists, including the great Aldo Leopold, to find and protect the Imperial woodpecker in its last habitat, Gallagher ventures deep into isolated territory, the high pine forests of Mexico’s Sierra Madre Occidental. In this mysterious, historically wild area, Geronimo led Apaches in their last stand and William Randolph Hearst inherited a storied ranch, which Pancho Villa looted. Today, drug lords rule the land.Here in the Sierra, the giant Imperial’s pounding drumbeat once echoed like the blows of an ax through the Sierra as it bored into the massive, grub-infested pines, hammering on them powerfully for weeks at a time until they groaned, shuddered, and finally toppled with a thunderous impact that shook the ground. The bird had largely disappeared by the early 1950s, yet rumors of Imperial Woodpeckers flying through remote forests persist.Gallagher’s quest takes a terrifying turn as he encounters armed drug traffickers, burning houses, and fleeing villagers. His passionate mission, now a life-and-death drama, will keep armchair adventurers on the edge of their seats as he chases truth in the most dangerous of habitats.
