Peterson Reference Guide to Sparrows of North America by Rick Wright Pdf
Sparrows are as complicated as they are common. This is an essential guide to identifying 76 kinds, along with a fascinating history of human interactions with them. What, exactly, is a sparrow? All birders (and many non‑birders) have essentially the same mental image of a pelican, a duck, or a flamingo, and a guide dedicated to waxwings or kingfishers would need nothing more than a sketch and a single sentence to satisfactorily identify its subject. Sparrows are harder to pin down. This book covers one family (Passerellidae), which includes towhees and juncos, and 76 members of the sparrow clan. Birds have a human history, too, beginning with their significance to native cultures and continuing through their discovery by science, their taxonomic fortunes and misfortunes, and their prospects for survival in a world with ever less space for wild creatures. This book includes not just facts and measurements, but stories--of how birds got their names and how they were discovered--of their entanglement with human history.

The North American Quails, Partridges, and Pheasants by Paul Johnsgard Pdf
This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel's, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly popular with naturalists, birders, and other outdoor enthusiasts.

Nourishing Waters, Comforting Sky by Stephen R. Jones Pdf
In the Nebraska Sandhills, ranchers on horseback and in pickup trucks share the range with pronghorn antelope, burrowing owls, and long-billed curlews. The native grasses grow greener as the cattle grow fatter. Throughout the region, river otters and mink swim in streams nourished by springs bubbling up from the High Plains (Ogallala) aquifer. Over years of close observation, Stephen R. Jones has gotten to know the Nebraska Sandhills—the twenty-thousand-square-mile expanse of stunning prairie and thriving wetlands. He has felt the warm breath of a white-tailed doe guarding her spotted fawn, learned to communicate with a family of long-eared owls, and developed an improbable hiking relationship with a wild turkey. He has documented a breeding bird population that is growing more diverse and witnessed the long-awaited return of nesting trumpeter swans. These personal stories, accompanied by words of insight from Native American leaders, Sandhills ranchers, and grassland ecologists, help us envision a quiet relationship with the natural world.

Bluebird Seasons by Mary Taylor Young Pdf
"This wonderful book is faithful both in its witness to the world's beauty and to our need to act now to preserve something of that wonder and grace. It brings the bracing air of the Rockies to us all." —Bill McKibben, author of The End of Nature In this A Sand County Almanac for the twenty-first century, nature writer and zoologist Mary Taylor Young tells the story of the growing effects of climate change on her land in the pine-covered foothills of southern Colorado. Climate change wasn't yet on the public radar when Young and her husband bought their piece of the wild in 1995. They built a cabin, set up a trail of bluebird nest boxes, and began a nature journal of observations, delighting in the ceaseless dramas, joys, and tragedies that are the fabric of life in the wild. But changes greater than the seasonal cycles of nature became evident over time: increasing drought, wildfires, bears delaying hibernation, and the decline of familiar birds and appearance of new species. Their journal of sightings over twenty-five bluebird seasons, she realized, was a record of climate change happening, not in an Indonesian rainforest or on an Antarctic ice sheet but in their own natural neighborhood. Using the journal as a chronicle of change, Young tells a story echoed in everyone's lives and backyards. But it's not time to despair, she writes. It's time to act. Young sees hope in the human ability to overcome great obstacles, in the energy and determination of young people, and in nature's resilience, which the bluebirds show season after season.

The North American Perching and Dabbling Ducks by Paul Johnsgard Pdf
This volume, the fourth in a series of books that collectively update and expand P.A. Johnsgard's 1975 The Waterfowl of North America, summarizes research findings on this economically and ecologically important group of waterfowl. The volume includes the mostly tropical perching duck tribe Cairinini, of which two species, the muscovy duck and the wood duck, are representatives. Both species are adapted for foraging on the water surface, mostly on plant materials, but typically perch in trees and nest in elevated tree cavities or other elevated recesses. This volume also includes the dabbling, or surface-feeding, duck tribe Anatini, a large assemblage of duck species that mainly forage on the water surface but nest on the ground, or only very rarely in elevated locations. Of this tribe, 12 species that regularly breed in North America are included, among them such familiar species as mallards, wigeons, pintails, and teal. Descriptive accounts of the distributions, populations, ecologies, social-sexual behaviors, and breeding biology of all these species are provided, together with distribution maps. Five additional Eurasian and West Indian species have been reported several times in North America; these have been included with more abbreviated accounts, but all 17 species are illustrated by drawings, photographs, or both. The text includes about 84,000 words and contains more than 1,000 references. There are also 12 distribution maps, 21 drawings, 28 photographic plates, and 58 anatomical or behavioral sketches.

The Pinyon Jay by John M. Marzluff,Russel P. Balda Pdf
A flock of Pinyon Jays arrive in a flash of blue, and leave again just as suddenly. This once mysterious bird is now the subject of over 20 years of intensive research involving over one thousand colour-marked jays by Russell Balda, John Marzluff and their colleagues and helpers. This plain blue bird has turned out to be anything but plain in its biology and behaviour. Uniquely dependent on the seeds of the Pinyon Pine for food, they have developed a number of behavioural and morphological adaptations to best utilise this resource, above all caching enough seeds each autumn to supply their needs throughout the winter and fuel their unusual habit of nesting in late winter. Fluctuations in pine-seed supply, both by season and between years, poses special problems for these birds and has led to their extremely flexible and complex social system in which learning and memory play an unusually large part. They store pine seeds and retrieve them with uncanny accuracy; they form lifelong pair bonds and nest colonially, occasionally involving younger birds to help established pairs rear the young; and they use their large vocabulary to coordinate activities within one of the largest known avian societies. This intriguing story will fascinate both the enthusiastic amateur birder and the professional alike. Packed with information, it presents Pinyon Jay biology in a readable form and places them into the wider context of studies on bird ecology and evolution. Fine illustrations by Tony Angell, with additional pictures by Caroline Bauder, complete this attractive addition to any birder's bookshelf.

The North American Whistling-Ducks, Pochards, and Stifftails by Paul Johnsgard Pdf
Although the 12 species representing three waterfowl tribes described in this volume are not closely related, they fortuitously provide an instructive example of adaptive evolutionary radiation within the much larger waterfowl lineage (the family Anatidae), especially as to their divergent morphologies, life histories, and social behaviors. The whistling-ducks (Dendrocygna), with three known North American species, are notable for their permanent pair-bonds, extended biparental family care, and strong social cohesion. In contrast, males of the five typical pochards of North American diving ducks (Aythya) establish monogamous pair-bonds that are maintained only long enough to assure that the female's eggs are fertilized. The endpoint of this behavioral gradient, promiscuity or polygyny, exists among at least some of the typical stifftails (Oxyura). Such diverse reproductive strategies have exerted powerful evolutionary influences on interspecies variations in sexual dimorphism, sexual behavior, anatomy, ecology, and other traits. This volume includes more than 63,000 words, plus some 200 maps, photos, drawings, and sketches, and nearly 650 literature citations. It is the last of five volumes that describe all 55 waterfowl species that have been historically documented in North America; collectively, the volumes total over 300,000 words, with nearly 3,000 literature citations, and more than 600 maps, photos, drawings, and sketches.
