Book excerpt: An in-depth biological overview of a fascinating group of waterfowl 'Paul A. Johnsgard's first glimpse of a North American ruddy duck--a chestnut-brown bird with a blue bill, black head, and white cheeks--led to decades of observing the eight extant species of stiff-tailed ducks. In Ruddy Ducks and Other Stifftails, he and Montserrat Carbonell introduce general readers and ornithologists to the ruddy's morphology, behavior, ecology, and diverse relatives. This richly illustrated volume highlights these unique species at a critical time, when their wetlands habitats are increasingly at risk.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: "Based on an analysis of 47 years (1967-2014) of Audubon Christmas Bird Counts (CBC), evidence for population changes and shifts in early winter (late December) ranges of nearly 150 species of birds in the Great Plains states is summarized, a region defined as including the Dakotas, Nebraska, Kansas, Oklahoma, and the Texas panhandle. The rationale for this study had its origins in Terry Root's 1988 Atlas of North American Wintering Birds. ... The present analysis includes all of the 40 annual CBC surveys from the 1967-8 to the 2006-7 counts, plus the results of the most recent 2013-14 CBC. The present summary quantitatively describes the early winter abundance for 147 of the most commonly encountered regional species, illustrating their temporal changes in geographic distributions and relative abundance between 1967 and 2014"--Publisher description.

Book excerpt: "Wildfowl and screamers belong to a highly diverse family of birds, confined to watery habitats. They are amongst the most attractive of birds and are very well-known to man, who has domesticated them, used their feathers for warm clothing and ornamentation, admired their flight, courtship and migration, caught them for food, maintained them in captivity for pleasure, and written about their doings in delightful children's stories, from Mother Goose to Jemima Puddleduck and Donald Duck. They occur throughout the world except Antarctica. Some are faithful to the same partner for life, others for only the few minutes of copulation. In some species, male and female make devoted parents, and yet there is one within the group whose female lays her eggs in the nests of others and never incubates. Diving as a method of obtaining food has evolved many times within the family. Most nest in the open but others in the tree-hole nests of woodpeckers and some in the ground burrows of rabbits or aardvarks. They may be highly social or solitary, defending a large territory." -- publisher website.

Book excerpt: George Miksch Sutton is one of the best known and most beloved bird artists of the twentieth century. This marvelous book presents thirty-five paintigs of downy chicks, nestlings, and fledglings painted from life by Sutton. The exquisite watercolrs, housed in the Field Museum of Natural History, span three decades and depict nineteen species of North American birds. Many of the paintings are reproduced here for the first time. Sutton was fond of painting young birds from life and of recording their developmental changes. Marked by delicate bruskwork and subtle color variations, his paintings document characteristic features of the birds’ species as well as capturing the poses and attributes that make each bird seem so unique. Some paintings show not only juvenal plumage but also head portraits of adult plumage. The nineteen species include familiar garden birds such as cardinals, Great Plains inhabitants such as the grassland sparrows, and upland and wetland birds, including bobwhites, moorhens, and sandpipers. In his introduction to the collection, ornithologist Paul Johnsgard discusses Sutton’s contributions to bird art and to ornithology. And is essays accompanying the paintings, Johnsgard describes his and Sutton’s personal encounters with the birds. A tribute to Sutton’s genius as both an artist and an ornithologist, Baby Bird Portraits will be welcomed by ornithologists, bird enthusiasts, and Sutton’s legion of admirers.

Book excerpt: This book profiles 60 of the most abundant, characteristic, and interesting birds that have been regularly reported from the Ucross Ranch and the adjacent Powder River Basin. The 20,000-acre Ucross Ranch lies on the western edge of the Powder River Basin of northeastern Wyoming. Ucross is a textbook example of the prairie grassland/shrubland habitat type referred to as the sagebrush steppe, a landscape that is an icon of Wyoming's vast open spaces.We focus especially on those species that occur year-round or are present as breeders during the summer months, and we place emphasis on a unique group of sagebrush steppe-adapted birds.

Book excerpt: These fourteen essays originally appeared in Prairie Fire, a monthly newspaper that for seven years has carried important messages of social, environmental, and economic issues to residents of Nebraska, Iowa, Colorado, and South Dakota, and subscribers in the rest of the world. They discuss the North American east-west ecological boundaries, spring migration events, bird feeders, feathered survivors of a glacial past, the threatened sharp-tailed grouse, the effects of climate change, some "sacred places"-Aransas National Wildlife Refuge, the Ashfall Fossil Beds, Squaw Creek Refuge, the Hutton Niobrara Ranch Sanctuary, and Yellowstone National Park-, our troubles with mountain lions and grizzly bears, and crane season in Wyoming. There is also an expanded informal autobiography, "My Life in Biology" and a current and comprehensive list of all publications of a writer described as "probably the world's most prolific living author of ornithological and natural history literature."

Available in PDF, EPUB and Kindle. Book excerpt: The young field of invasion biology - initially a branch of ecology and conservation biology - has greatly expanded, particularly in the last two and a half decades or so. As a result, the potential negative effects of introduced species have been widely advertised and sometimes, perhaps, overemphasized. This book attempts to restore some balance to the current debate over the role of non-native species, by offering a broader perspective, and taking a longer term, evolutionary look at these species and their impact in their new environments. The relatively arbitrary nature of terms such as "native" and "non-native", and the rather inconsistent ways in which such terms are applied to biological species, as well as the subjective boundaries of so-called "native ranges" are analyzed. The role of non-native species in their new environments can be considerably more complex than the anti-introduced species information would often suggest. Thus, the more positive and nuanced perspective on introduced species and their impact offered in this book is much needed and long overdue.
