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: "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.

Available in PDF, EPUB and Kindle. Book excerpt: In this beautifully illustrated guide, two practicing wildlife biologists describe the life histories of forty-five species of ducks, geese, and swans that occur in Texas. For common species and those that breed in the state, each account begins with an interesting fact (such as, “Red-breasted Mergansers have been clocked at over 80 mph, the fastest recorded flight speed for a duck . . .”) and provides information on Texas distribution and harvest, population status, diet, range and habitats, reproduction, and appearance. Exquisite photographs, informative distribution maps, and a helpful source list accompany the species descriptions, and the book offers a glossary and full bibliography for those who want to explore the literature further. With the degradation and disappearance of the inland and coastal habitats that these birds depend upon, the natural history of these waterfowl species provides a vital reminder of the interconnectedness and crucial importance of all wetlands. Birders, biologists, landowners, hunters, outdoor enthusiasts, and all those interested in the health and preservation of our coastal and inland wetland resources will enjoy and learn from this book.

Book excerpt: This annotated list of the birds of Nebraska grew gradually out of research associated with my writing of the Birds of the Great Plains: Breeding Species and Their Distribution (Johnsgard, 1979a). It expands and updates an earlier version that was published in 2013 by the University of Nebraska–Lincoln Libraries DigitalCommons’ Zea Books (Johnsgard, 2013a). It has been updated and modified in its current revision to conform with the most recent (2017) major revision of the American Ornithologists’ Society’s Checklist of North American Birds (Chesser et al., 2017). It has also been modified in its current revision to conform very closely to the most recent “Official List of the Birds of Nebraska” by the Nebraska Ornithologists’ Union (Gubanyi, 1997, and later supplements in the Nebraska Bird Review, to 84:138–150). The NOU’s official state list of birds (461 species as of 2017) is based on actual specimen evidence or some other convincing basis of each species’ proven occurrence in the state. That list includes 337 “regular” species, 29 “casual” species, 90 “accidental” species, and 5 extinct or extirpated species. In this edition I have classified 368 of the 461 species of Nebraska birds as ranging in relative frequency of occurrence as “abundant” to “rare.” There are also 61 species considered to be of “accidental” occurrence, having been reliably reported in Nebraska no more than five times, 20 that are considered “extremely rare” or “very rare,” if reported from six to 25 times. There are also three extinct, four extirpated, and five unsuccessfully introduced species. Thirteen hypothetical species of dubious origin or identification are mentioned parenthetically. The text includes more than 123,000 words, nearly 200 literature references, and 19 pages of drawings and maps.

Available in PDF, EPUB and Kindle. Book excerpt: The evolutionary, ecological and behavioral questions posed by obligate brood parasites are among the most intriguing of all contemporary ornithological topics. Avian brood parasites lay their eggs in the nests of other birds and may be a major contributing factor driving several species of songbirds to near extinction. As one of the first books to present a comprehensive overview of this fascinating phenomenon, this work discusses the comparative biology and co-evolutionary adaptations exhibited by the five families of birds that engage in such behavior. Several chapters dealing with the comparative biology of both intraspecific and interspecific brood parasites, are followed by individual accounts of all known species--nearly 100 altogether, primarily cowbirds and cuckoos. Some of the more remarkable behavioral and structural adaptations of these birds include egg mimicry, juvenile mimicry, elimination by starvation or actual attack of other nestlings or host eggs, and even the learning and partial mimicry of host song traits. An extended glossary, a list of Latin names, 400 literature citations and range maps of all parasitic species discussed are also included. Detailed line drawings by the author enhance this synthesis of biological and ecological information.

Available in PDF, EPUB and Kindle. Book excerpt: Whether it's the sudden, plunging dives of Brown Pelicans, the singing and aerial displays of Northern Mockingbirds, or the communal nesting of Purple Martins, innate and learned behaviors are some of the most fascinating things to observe in Texas birds. Even casual birdwatchers eventually ask, "why do they do that?" while serious birders and ornithologists seek to understand all the behaviors involved in feeding, flying, mating, and rearing young. But until now, it has been hard to find this information in one handy source. In this comprehensive, yet easy-to-use book, Kent Rylander distills data from many sources to provide an authoritative guide to the behavior of Texas birds. He begins by explaining the principles of animal behavior and illustrating how they can be applied to interpreting bird behaviors in the field. The majority of the book is devoted to accounts of more than 400 species of birds that are most likely to be encountered by Texas birdwatchers. Each account describes such behaviors as feeding, courtship, parenting, and other behaviors that are significant for that species. References to interesting and important articles from scientific journals are incorporated in the species accounts where appropriate, and line drawings illustrate some of the behaviors described.
