Book Description
“Reveals the strange and wondrous adaptations birds rely on to get by.” —National Audubon Society When we see a bird flying from branch to branch happily chirping, it is easy to imagine they lead a simple life of freedom, flight, and feathers. What we don’t see is the arduous, life-threatening challenges they face at every moment. Beaks, Bones, and Bird Songs guides the reader through the myriad, and often almost miraculous, things that birds do every day to merely stay alive. Like the goldfinch, which manages extreme weather changes by doubling the density of its plumage in winter. Or urban birds, which navigate traffic through a keen understanding of posted speed limits. In engaging and accessible prose, Roger Lederer shares how and why birds use their sensory abilities to see ultraviolet, find food without seeing it, fly thousands of miles without stopping, change their songs in noisy cities, navigate by smell, and much more.

A Wing and a Prayer PDF Author: Anders Gyllenhaal
Publisher: Simon and Schuster
ISBN: 1982184558
Category : Biography & Autobiography
Languages : en
Pages : 320

Book Description
A captivating drama from the frontlines of the race to save birds set against the devastating loss of one third of the avian population. Three years ago, headlines delivered shocking news: nearly three billion birds in North America have vanished over the past fifty years. No species has been spared, from the most delicate jeweled hummingbirds to scrappy black crows, from a rainbow of warblers to common birds such as owls and sparrows. In a desperate race against time, scientists, conservationists, birders, wildlife officers, and philanthropists are scrambling to halt the collapse of species with bold, experimental, and sometimes risky rescue missions. High in the mountains of Hawaii, biologists are about to release clouds of laboratory-bred mosquitos in a last-ditch attempt to save Hawaii’s remaining native forest birds. In Central Florida, researchers have found a way to hatch Florida Grasshopper Sparrows in captivity to rebuild a species down to its last two dozen birds. In the Sierra Nevada Mountains, a team is using artificial intelligence to save the California Spotted Owl. In North Carolina, a scientist is experimenting with genomics borrowed from human medicine to bring the long-extinct Passenger Pigeon back to life. For the past year, veteran journalists Anders and Beverly Gyllenhaal traveled more than 25,000 miles across the Americas, chronicling costly experiments, contentious politics, and new technologies to save our beloved birds from the brink of extinction. Through this compelling drama, A Wing and a Prayer offers hope and an urgent call to action: Birds are dying at an unprecedented pace. But there are encouraging breakthroughs across the hemisphere and still time to change course, if we act quickly.

Book Description
Oxford Studies in Early Modern Philosophy is an annual series, presenting a selection of the best current work in the history of early modern philosophy. It focuses on the seventeenth and eighteenth centuries--the extraordinary period of intellectual flourishing that begins, very roughly, with Descartes and his contemporaries and ends with Kant. It also publishes papers on thinkers or movements outside of that framework, provided they are important in illuminating early modern thought. The articles in OSEMP will be of importance to specialists within the discipline, but the editors also intend that they should appeal to a larger audience of philosophers, intellectual historians, and others who are interested in the development of modern thought.

Gyrfalcon

Gyrfalcon PDF Author: Norman Barichello
Publisher: FriesenPress
ISBN: 1525551043
Category : Nature
Languages : en
Pages : 183

Book Description
Gyrfalcons and humans have shared a remarkable relationship since prehistoric times. These extraordinary arctic falcons have been revered, coveted as an item of commerce, persecuted, and enjoyed as a spectacle of sport for at least ten thousand years. Today, climate change has brought new challenges, with habitat in the far north changing rapidly as natural cycles begin to break down. Drawn from over thirty years of study and observation, this in-depth study provides a comprehensive view of the gyrfalcon’s place in the arctic ecosystem, including their inextricable link to their primary pray, the ptarmigan, and their antagonistic relationship with golden eagles. It explores the connection the bird has had with humanity in both legend and practice, and the challenges it faces as its habitat continues to change. This definitive look at the gyrfalcon shows us both sides of the majestic bird: the master of its domain and a threatened species facing an uncertain future.
