This friendly, relatable book is a celebration of the art, science, and delights of bird-watching.How to Know the Birds introduces a new, holistic approach to bird-watching, by noting how behaviors, settings, and seasonal cycles connect with shape, song, color, gender, age distinctions, and other features traditionally used to identify species. With short essays on 200 observable species, expert author Ted Floyd guides us through a year of becoming a better birder, each species representing another useful lesson: from explaining scientific nomenclature to noting how plumage changes with age, from chronicling migration patterns to noting hatchling habits. Dozens of endearing pencil sketches accompany Floyd's charming prose, making this book a unique blend of narrative and field guide. A pleasure for birders of all ages, this witty book promises solid lessons for the beginner and smiles of recognition for the seasoned nature lover.

    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.

    Go on a journey––back to when dinosaurs ruled the Earth––to discover how dinosaurs achieved feats unparalleled by any other group of animals. Learn the secrets of how paleontologists find fossils, and explore quirky, but profound questions, such as: Is a penguin a dinosaur? And, how are the tiny arms of T. rex the key to its power and ferocity? In this revealing book, Lacovara offers the latest ideas about the shocking and calamitous death of the dinosaurs and ties their vulnerabilities to our own. Why Dinosaurs Matter is compelling and engaging—a great reminder that our place on this planet is both precarious and potentially fleeting. “As we move into an uncertain environmental future, it has never been more important to understand the past.”

    Earthbound, we can only look and listen, enjoying their lightness, freedom and richness of plumage and song.David Attenborough has been watching and learning all his life. His new book, with its accompanying series of films for BBC TV, is a brilliant introduction to bird behaviours around the world: what they do and why they do it. He looks at each step in birds' lives and the problems they have to solve: learning to fly; finding food; communicating; mating and caring for nests, eggs and young; migrating; facing dangers and surviving harsh conditions.Sir David has no equal in helping others to learn and making it exciting. His curiosity and enjoyment are infectious. He shows the lifelong pleasure that birds around us offer, and how much we miss if unaware of them.

    In reality, he writes, “the lobster fisherman is caught up in a thick and complex web of social relationships. Survival in the industry depends as much on the ability to manipulate social relationships as on technical skills.” Acheson replaces our romantic image of the lobsterman with descriptions of the highly territorial and hierarchical “harbor gangs,” daily and annual cycles of lobstering, intricacies of marketing the catch, and the challenge of managing a communal resource.

    It offers superior coverage of all key areas, including descriptive chemistry, MO theory, bonding, and physical inorganic chemistry.

    But they are relative newcomers there. They evolved in North America and retain their greatest diversity in South America, while the only wild dromedaries are in Australia.This is a classic example of the contradictions of 'native' and 'invasive' species, a hot issue right now as the flip-side of biodiversity. Do we need to fear invaders? Can we control them? Do we choose the right targets? And are the natives always good guys?Thompson puts forward a fascinating array of narratives to explore this crucial question.

    Called orca by some, and killer whales by others, these mysterious animals have become part of Ingrid's life. She has got to know many orca by sight and calls them her friends. Her experiences with orca challenge their fearsome reputation: she gets into the water with them, watches them hunt, and communicates in any way she can. Ingrid is the only orca researcher working in the South Pacific. This book details her fascinating discoveries, as well as telling her own personal story and describing her amazing adventures.

    Once one of the continent’s most ubiquitous mammals, they ranged from the Atlantic to the Pacific, and from the Rio Grande to the edge of the northern tundra. Wherever there was wood and water, there were beavers — 60 million (or more) — and wherever there were beavers, there were intricate natural communities that depended on their activities. Then the European fur traders arrived.In Once They Were Hats, Frances Backhouse examines humanity’s 15,000-year relationship with Castor canadensis, and the beaver’s even older relationship with North American landscapes and ecosystems. From the waterlogged environs of the Beaver Capital of Canada to the wilderness cabin that controversial conservationist Grey Owl shared with pet beavers, Backhouse goes on a journey of discovery to find out what happened after we nearly wiped this essential animal off the map, and how we can learn to live with beavers now that they’re returning.

    The down beats of their wings would chill the air beneath and create a thundering roar that would drown out all other sound. Feeding flocks would appear as “a blue wave four or five feet high rolling toward you.”John James Audubon, impressed by their speed and agility, said a lone passenger pigeon streaking through the forest “passes like a thought.” How prophetic-for although a billion pigeons crossed the skies 80 miles from Toronto in May of 1860, little more than fifty years later passenger pigeons were extinct. The last of the species, Martha, died in captivity at the Cincinnati Zoo on September 1, 1914.As naturalist Joel Greenberg relates in gripping detail, the pigeons' propensity to nest, roost, and fly together in vast numbers made them vulnerable to unremitting market and recreational hunting. The spread of railroads and telegraph lines created national markets that allowed the birds to be pursued relentlessly. Passenger pigeons inspired awe in the likes of Audubon, Henry David Thoreau, James Fenimore Cooper, and others, but no serious effort was made to protect the species until it was way too late. Greenberg's beautifully written story of the passenger pigeon provides a cautionary tale of what happens when species and natural resources are not harvested sustainably.

    Across North America, tens of thousands of people gather every spring and fall at more than one thousand known hawk migration sites--from New Jersey's Cape May to California's Golden Gate. Yet, as many discover, a standard field guide, with its emphasis on plumage, is often of little help in identifying those raptors soaring, gliding, or flapping far, far away.Hawks from Every Angle takes hawk identification to new heights. It offers a fresh approach that literally looks at the birds from every angle, compares and contrasts deceptively similar species, and provides the pictures (and words) needed for identification in the field. Jerry Liguori pinpoints innovative, field-tested identification traits for each species from the various angles that they are seen.Featuring 339 striking color photos on 68 color plates and 32 black & white photos, Hawks from Every Angle is unique in presenting a host of meticulously crafted pictures for each of the 19 species it covers in detail--the species most common to migration sites throughout the United States and Canada. All aspects of raptor identification are discussed, including plumage, shape, and flight style traits.For all birders who follow hawk migration and have found themselves wondering if the raptor in the sky matches the one in the guide, Hawks from Every Angle--distilling an expert's years of experience for the first time into a comprehensive array of truly useful photos and other pointers for each species--is quite simply a must.Key Features?
