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.

    By some estimates, we may already have lost almost half of the songbirds that filled the skies only forty years ago. Renowned biologist Bridget Stutchbury convincingly argues that songbirds truly are the "canaries in the coal mine"--except the coal mine looks a lot like Earth and we are the hapless excavators.Following the birds on their six-thousand-mile migratory journey, Stutchbury leads us on an ecological field trip to explore firsthand the major threats to songbirds: pesticides, still a major concern decades after Rachel Carson first raised the alarm; the destruction of vital habitat, from the boreal forests of Canada to the diminishing continuous forests of the United States to the grasslands of Argentina; coffee plantations, which push birds out of their forest refuges so we can have our morning fix; the bright lights and structures in our cities, which prove a minefield for migrating birds; and global warming. We could well wake up in the near future and hear no songbirds singing. But we won't just be missing their cheery calls, we'll be missing a vital part of our ecosystem. Without songbirds, our forests would face uncontrolled insect infestations, and our trees, flowers, and gardens would lose a crucial element in their reproductive cycle. As Stutchbury shows, saving songbirds means protecting our ecosystem and ultimately ourselves.Some of the threats to songbirds: - The U.S. annually uses 4-5 million pounds of active ingredient acephate, an insecticide that, even in small quantities, throws off the navigation systems of White-throated sparrows and other songbirds, making them unable to tell north from south. - The U.S. Fish and Wildlife Service conservatively estimated that 4-5 million birds are killed by crashing into communication towers each year.- A Michigan study found that 600 domestic cats killed more than 6,000 birds during a typical 10-week breeding season. Wood thrush, Kentucky warbler, the Eastern kingbird--migratory songbirds are disappearing at a frightening rate.

    In Don't Look Behind You, Allison recounts adventures few would live to tell.

    After Congress viewed photos of Yosemite, President Lincoln was moved to sign a bill that paved the way for the U.S. National Park Service, which was founded in 1916 and is now celebrating its centennial. In Treasured Lands: A Photographic Odyssey Through America's National Parks, photographer QT Luong pays tribute to the millions of acres of protected wilderness in our country's 59 national parks. Luong, who is featured in Ken Burns's and Dayton Duncan's documentary The National Parks: America's Best Idea, is one the most prolific photographers working in the national parks and the only one to have made large-format photographs in each of them. In an odyssey that spanned more than 20 years and 300 visits, Luong focused his lenses on iconic landscapes and rarely seen remote views, presenting his journey in this sumptuous array of more than 500 breathtaking images. Accompanying the collection of scenic masterpieces is a guide that includes maps of each park, as well as extended captions that detail where and how the photographs were made. Designed to inspire visitors to connect with the parks and invite photographers to re-create these landscapes, the guide also provides anecdotal observations that give context to the pictures and convey the sheer scope of Luong's extraordinary odyssey. Including an introduction by award-winning author and documentary filmmaker Dayton Duncan, Treasured Lands is a rich visual tour of the U.S. National Parks and an invaluable guide from a photographer who hiked - or paddled, dived, skied, snowshoed, and climbed - each park, shooting in all kinds of terrain, in all seasons, and at all times of day. QT Luong's timeless gallery of the nation's most revered landscapes beckons to nature lovers, armchair travelers, and photography enthusiasts alike, keeping America's natural wonders within reach.
