"Birds of the Middle San Pedro Valley of Southeast Arizona" offers a fresh and unique view of bird life that is both personal and engaging. Not long after retiring from his practice as a medical doctor, Michael Whitt desired to publish a book on the birds that he and his wife, Barbara, had photographed on their property along the San Pedro River in southeast Arizona. With a sharp eye, excellent observational skills, and a keen intellect characteristic of those in his profession, Whitt gives us an intimate portrait of avian life backed by more than eighty years of wisdom and decades of close, astute observations in the outdoors. The beautifully eloquent lines of poetry that complement the text reveal an author with the insights of a true naturalist and a genuine passion for the birds and the wild lands that they require to survive.

"The multiple, vivid colors of scarlet macaws and their ability to mimic human speech are key reasons they were and are significant to the Native peoples of the southwestern U.S. and northwest New Mexico. Although the birds' natural habitat is the tropical forests of Mexico and Central America, they were present at multiple archaeological sites in the region. Leading experts in southwestern archaeology explore the reasons why"--

Woody wetlands constitute a relatively small but extremely important part of the landscape in the southwestern United States. These riparian habitats support more than one-third of the regionÕs vascular plant species, are home to a variety of wildlife, and provide essential havens for dozens of migratory animals. Because of their limited size and disproportionately high biological value, the goal of protecting wetland environments frequently takes priority over nearly all other habitat types. In The Ribbon of Green, hydrologists Robert H. Webb, and Stanley A. Leake and botanist Raymond M. Turner examine the factors that affect the stability of woody riparian vegetation, one of the largest components of riparian areas. Such factors include the diversion of surface water, flood control, and the excessive use of groundwater. Combining repeat photography with historical context and information on species composition, they document more than 140 years of change. Contrary to the common assumption of widespread losses of this type of ecosystem, the authors show that vegetation has increased on many river reaches as a result of flood control, favorable climatic conditions, and large winter floods that encourage ecosystem disturbance, germination, and the establishment of species in newly generated openings. Bringing well-documented and accessible insights to the ecological study of wetlands, this book will influence our perception of change in riparian ecosystems and how riparian restoration is practiced in the Southwest, and it will serve as an important reference in courses on plant ecology, riparian ecology, and ecosystem management.

The rare treasure of a desert river rises in Sonora, Mexico to flow into the state of Arizona. Known as the San Pedro, its story is phenomenal. The river and its watershed have become a Mecca for birdwatchers from all over the globe. The forests lining the river's banks and the mountains that flank its valleys are home to an astounding array of unique plants and animals. Within these pages, the land and its life are unveiled in a very uncommon way-through the eyes of an acclaimed naturalist whose knowledge has come directly from thousands of miles of walking in the American West and a lifelong study of the natural world. "The Life of the San Pedro" reveals an incredible landscape, a part of North America that is beyond comparison.

Describes over 400 species. Includes background on the natural history of the region, records of sightings, and distribution maps. Many illustrations.

Carved from cliffs and canyons, buried in desert rock and sand are pieces of the ancient past that beckon thousands of visitors every year to the American Southwest. Whether Montezuma Castle or a chunk of pottery, these traces of prehistory also bring archaeologists from all over the world, and their work gives us fresh insight and information on an almost day-to-day basis. Who hasn't dreamed of boarding a time machine for a trip into the past? This book invites us to step into a Hohokam village with its sounds of barking dogs, children's laughter, and the ever-present grinding of mano on metate to produce the daily bread. Here, too, readers will marvel at the skills of Clovis elephant hunters and touch the lives of other ancestral people known as Mogollon, Anasazi, Sinagua, and Salado. Descriptions of long-ago people are balanced with tales about the archaeologists who have devoted their lives to learning more about "those who came before." Trekking through the desert with the famed Emil Haury, readers will stumble upon Ventana Cave, his "answer to a prayer." With amateur archaeologist Richard Wetherill, they will sense the peril of crossing the flooded San Juan River on the way to Chaco Canyon. Others profiled in the book are A. V. Kidder, Andrew Ellicott Douglass, Julian Hayden, Harold S. Gladwin, and many more names synonymous with the continuing saga of southwestern archaeology. This book is an open invitation to general readers to join in solving the great archaeological puzzles of this part of the world. Moreover, it is the only up-to-date summary of a field advancing so rapidly that much of the material is new even to professional archaeologists. Lively and fast paced, the book will appeal to anyone who finds magic in a broken bowl or pueblo wall touched by human hands hundreds of years ago. For all readers, these pages offer a sense of adventure, that "you are there" stir of excitement that comes only with making new discoveries about the distant past.

Examines over 270 species of birds known to breed in Arizona, complete with color photos and nesting and migratory data.
