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.

Among birds, swans are relatively long-lived species and are also among the most strongly monogamous, having prolonged pair and family bonds that strongly influence their reproductive and general social behavior, which, in combination with their beauty and elegance, contribute to the overall high degree of worldwide human interest in them. This volume of more than 59,000 words describes the distributions, ecology, social behavior, and breeding biologies of the four species of swans that breed or have historically bred in North America, including the native trumpeter and tundra swans, the introduced mute swan, and the marginally occurring whooper swan. Also included are 5 distribution maps, 15 drawings, 27 photographs by the author, and a reference section of nearly 1,000 literature citations.

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.

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.

In Wildlife of Nebraska: A Natural History, Paul A. Johnsgard surveys the variety and biology of more than six hundred Nebraska species. Narrative accounts describe the ecology and biology of the state's birds, its mammals, and its reptiles and amphibians, summarizing the abundance, distributions, and habitats of this wildlife. To provide an introduction to the state's major ecosystems, climate, and topography, Johnsgard examines major public-access natural areas, including national monuments, wildlife refuges and grasslands, state parks and wildlife management areas, and nature preserves. Including more than thirty-five line drawings by the author along with physiographic, ecological, and historical maps, Wildlife of Nebraska is an essential guide to the wildlife of the Cornhusker State.

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.

A Dictionary of Birds enlists contributions from over 280 ornithologists and other specialists from around the world. Major, authoritative articles cover the field of modern ornithology and related subjects, many of them running to several thousand words. In addition there are articles on all the bird families, almost all of which are illustrated by a representative species. There are also numerous short entries defining special terms, application of names, etc. The total gives a text of over 800,000 words, supported by more than 500 photographs, drawings and diagrams. The photographs have been selected under the guidance of Eric Hosking to illustrate different activities of birds, and Robert Gillmor has assembled a collection of over 200 drawings of birds, almost all of which were specially drawn for the Dictionary. Compiled for the British Ornithologists' Union, this new work is in line of succession from Newton's A Dictionary of Birds of 1896 and Landsborough Thomson's A New Dictionary of Birds published in 1964 (2nd impression 1965) and now long out of print. This dictionary, encyclopedic in treatment, is destined to be a major reference in any ornithologist's library; and its editors and contributors, most of whom gave their time and knowledge freely, have earned the thanks and acclaim of users for many years to come.

With more than 10,000 species that vary in size, use diverse habitats that extend across latitudes and altitudes, consume a wide variety of food items, differ in how they fly (or not), communicate, and reproduce, and have different life histories, birds exhibit remarkable variation in form (anatomy) and function (physiology). Our understanding of how natural selection has generated this variation as birds evolved and as different species adapted to their unique circumstances has grown considerably in recent years. In In a Class of Their Own: A Detailed Examination of Avian Forms and Functions, this variation is explained in great detail, beginning with an overview of avian evolution and continuing with information about the structure and function of the avian skeleton, muscles, and the various body systems. Other chapters focus on avian locomotion (including flight), migration, navigation, communication, energy balance and thermoregulation, and various aspects of avian reproduction, such as nests and nest building, clutch sizes, and parental care. In a Class of Their Own: A Detailed Examination of Avian Forms and Functions will be must reading for anyone, professional or non-professional, who needs or wants to learn more about birds.

"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.
